Generative AI Experiments: The Surprisingly Poor Performance Of LLM-Based Geocoders, Geographic Bias & Why GPT 3.5 & Gemini Pro Outperform GPT 4.0 In Underrepresented Geographies

Last year we explored the potential of LLMs to be used as general purpose entity extraction models, finding that LLMs perform extremely poorly on generalized entity extraction due to their lack of underlying live-updating knowledge graph. In each of those tests, we examined generalized entity extraction over the open domain of person and organization names, in which there is an infinite open-ended universe of possibilities. In contrast, textual geocoding (converting a textual mention of a location like "Paris" into a disambiguated geographic centroid record) offers a much simpler challenge for which LLMs might be far more readily amenable, given the relatively fixed nature of global geographic names. (In reality, geographic names change constantly, but for most traditional geocoding tasks, even if the underlying gazetteer only updates annually, this may be acceptable).

To explore this further, we examine two articles, one about Ukraine and one about India, and test a range of prompts with GPT 3.5, GPT 4.0 and Gemini Pro.

For the Ukraine article that mentions only a handful of country, major city and ADM1 locations that have received extensive global media coverage (and thus should be extremely well represented in the models' training data), GPT 3.5 performs fairly poorly, with highly inconsistent results, hallucination and missing even major cities like Moscow. Even with our most advanced prompt, incorporating step-by-step reasoning and explanation, coherence and counter-hallucination instructions and snippet requests, GPT 3.5 consistently fails to accurately extract all of the locations in the Ukraine article. GPT 4.0 is able to regurgitate ADM1 labels and centroid lat/long coordinates from its training data, but hallucinates and has unstable extraction. Only with the most advanced prompt does GPT 4.0 provide strong results for Ukraine. Gemini Pro experiences high instability and low coherence, changing the list of locations it identifies with each run, excluding major locations, hallucinating locations and triggering a guardrail false positive that prevents output in a third of the tests. GPT 4.0 is the clear winner here, though even its results are not competitive with classical dedicated geocoding algorithms.

The India article was selected to explore how well models perform on the majority of locations across the world that are unlikely to be heavily represented in the English language training data of the three models. It also tests the models' ability to handle local administrative division references like "taluka" and "tehsil". Here, all three models performed exceptionally poorly, as expected. Surprisingly, GPT-4.0 using the most advanced prompts performed the worst of the three models, illustrating that more advanced models don't necessarily yield more accurate results. In this case, GPT-4.0 struggled both with India's unique administrative divisions (a byproduct of OpenAI's failure to properly globalize its models) and with surprisingly more mundane recognition failures. GPT 3.5 performed better than 4.0 in this case due to its simpler and more naive name extraction. In other words, GPT 4.0's more advanced capabilities meant it attempted to perform greater processing on names, which ended up failing due to its training data's bias against Indian toponyms. Gemini Pro performed surprisingly well and vastly exceeded GPT 4.0's performance, but it too performed fairly poorly.

In all, the three models performed better at geocoding than open-ended entity extraction, but still performed abysmally compared with classical dedicated entity extraction systems. Note that we did not test disambiguation capabilities of the models, only their extractive capabilities and thus the abysmal performance here reflects only the first stage of a geocoding system. Like all things LLM, instability, coherence failure, hallucination and bias all combine to render LLMs unsuitable for production geocoding tasks. The much lower performance of GPT 4.0 compared with 3.5 on Indian locations reflects that more advanced models can enforce greater bias and globalization failures that lower than performance and thus more advanced models are not always better. The failure of all three models on Indian locations reinforces the extreme bias of current LLM models and their underlying training data.

 

As a simple experiment, what if we take this Al Jazeera article about Ukraine and see how GPT 3.5, GPT 4.0 and Gemini Pro geocode it?

GPT 3.5

Let's start with GPT 3.5:

You are a geocoding agent, your job is to read text and compile a list of all geographic locations mentioned within. 
Make a list of all of the geographic locations mentioned in the text below. 
Output in the following JSON format: "{ city: "City Name", ADM1: ADM1, Country: Country Name, Lat: Latitude, Long: Longitude }":
TEXT:

This yields the following list, which captures the locations and interestingly changes our "city" parameter to "city/region/country", but fails to output JSON:

Here is a list of geographic locations mentioned in the provided text:

1. City: Kyiv, ADM1: N/A, Country: Ukraine, Lat: N/A, Long: N/A
2. Country: Russia, ADM1: N/A, Lat: N/A, Long: N/A
3. Region: Sumy, ADM1: N/A, Country: Ukraine, Lat: N/A, Long: N/A
4. Region: Chernihiv, ADM1: N/A, Country: Ukraine, Lat: N/A, Long: N/A
5. Country: Poland, ADM1: N/A, Lat: N/A, Long: N/A
6. Country: France, ADM1: N/A, Lat: N/A, Long: N/A
7. Country: United Kingdom, ADM1: N/A, Lat: N/A, Long: N/A

Please note that some locations do not have specific latitude and longitude coordinates mentioned in the text, so they are marked as "N/A" in the JSON format.

What if we run a second time? This time we get JSON, but it inserts false ADM1s. It also uses the requested "city" field, illustrating the coherence challenges of LLMs where in the first response above it adlibbed a different field for city. This time it also adds the "European Union" as a location:

Here is a list of geographic locations mentioned in the text along with their respective information in JSON format:

1. {"city": "Kyiv", "ADM1": null, "Country": "Ukraine", "Lat": null, "Long": null}
2. {"city": "Moscow", "ADM1": null, "Country": "Russia", "Lat": null, "Long": null}
3. {"city": "Sumy", "ADM1": "northeastern Sumy region", "Country": "Ukraine", "Lat": null, "Long": null}
4. {"city": "Chernihiv", "ADM1": "northern region of Chernihiv", "Country": "Ukraine", "Lat": null, "Long": null}
5. {"city": "Poland", "ADM1": null, "Country": "Poland", "Lat": null, "Long": null}
6. {"city": "France", "ADM1": null, "Country": "France", "Lat": null, "Long": null}
7. {"city": "European Union", "ADM1": null, "Country": "European Union", "Lat": null, "Long": null}
8. {"city": "Britain", "ADM1": null, "Country": "United Kingdom", "Lat": null, "Long": null}

Please note that some locations have limited geographic coordinates available, and some are countries or regions without specific city information mentioned in the text.

Running a third time the results are largely the same:

Here is a list of geographic locations mentioned in the text along with their respective information in JSON format:

1. {"city": "Kyiv", "ADM1": null, "Country": "Ukraine", "Lat": null, "Long": null}
2. {"city": "Moscow", "ADM1": null, "Country": "Russia", "Lat": null, "Long": null}
3. {"city": "Sumy", "ADM1": "northeastern Sumy region", "Country": "Ukraine", "Lat": null, "Long": null}
4. {"city": "Chernihiv", "ADM1": "northern region of Chernihiv", "Country": "Ukraine", "Lat": null, "Long": null}
5. {"city": "Poland", "ADM1": null, "Country": "Poland", "Lat": null, "Long": null}
6. {"city": "France", "ADM1": null, "Country": "France", "Lat": null, "Long": null}
7. {"city": "European Union", "ADM1": null, "Country": "European Union", "Lat": null, "Long": null}
8. {"city": "Britain", "ADM1": null, "Country": "United Kingdom", "Lat": null, "Long": null}

Please note that some locations have limited geographic coordinates available, and some are countries or regions without specific city information mentioned in the text.

How about a fourth time? This time we get an infinite loop – the first time we've seen an LLM infinite loop in an OpenAI product in our testing. The output below is truncated to the first 50 rows, while in reality the results were aborted after continuing indefinitely up to token max length:

...

What if we modify our prompt slightly to request that all of the results be returned in a single JSON array, rather than in JSON-NL (one object per line) format:

You are a geocoding agent, your job is to read text and compile a list of all geographic locations mentioned within. 
Make a list of all of the geographic locations mentioned in the text below. 
Output in the following JSON format: "{ city: "City Name", ADM1: ADM1, Country: Country Name, Lat: Latitude, Long: Longitude }", with all of the locations in a single JSON array:
TEXT:

The first time it fails to return JSON:

Here is a list of geographic locations mentioned in the provided text:

1. City: Kyiv, ADM1: N/A, Country: Ukraine, Lat: N/A, Long: N/A
2. Country: Russia, ADM1: N/A, City: N/A, Lat: N/A, Long: N/A

10. City: London, ADM1: N/A, Country: United Kingdom, Lat: N/A, Long: N/A

Please note that some locations are mentioned without specific latitude (Lat) and longitude (Long) coordinates, and some are mentioned without an Administrative Division 1 (ADM1) designation.

The second time we get JSON:

Here is a list of geographic locations mentioned in the text in JSON format:

```json

```

Please note that some locations may not have latitude and longitude coordinates provided in the text, so those fields are left empty.

Finally, what if we try a far more elaborate prompt that includes step-by-step reasoning explanation, explicit instruction to include all mentioned locations and none not mentioned and a verification snippet, as well as adjusting our JSON to emphasize that we are looking for all locations rather than just cities:

You are a geocoding agent, your job is to read text and compile a list of all geographic locations mentioned within.
Make a list of all of the geographic locations mentioned in the text below.
Output in the following JSON format: "{ location: "Location Name", ADM1: ADM1, Country: Country Name, Lat: Latitude, Long: Longitude, Explanation: Explanation, Snippet: Snippet }", with all of the locations in a single JSON array.
Do not include any locations not mentioned in the text and make sure to include all locations mentioned in the text. For the Explanation field explain your reasoning for including that location step-by-step.
For the Snippet field include a brief snippet from the text that includes a mention of that location.
TEXT:

This JSON list includes all the geographic locations mentioned in the text along with their respective ADM1, Country, Latitude, Longitude, Explanation, and a snippet from the text that mentions each location.

 

GPT 4.0

Let's try the original prompt with GPT 4.0:

You are a geocoding agent, your job is to read text and compile a list of all geographic locations mentioned within. 
Make a list of all of the geographic locations mentioned in the text below. 
Output in the following JSON format: "{ city: "City Name", ADM1: ADM1, Country: Country Name, Lat: Latitude, Long: Longitude }":
TEXT:

This time we get JSON output that matches our requested format and GPT 4.0 has even estimated values for each field, including centroid lat/long. It even seems to provide accurate centroid values for each. Interestingly, the European Union is not considered a geographic location (it isn't filtering just to cities, as countries appear below):

Based on the text provided, here are the geographic locations mentioned along with their respective details in the requested JSON format:

1. 
```json
{
  "city": "Kyiv",
  "ADM1": "Kyiv City",
  "Country": "Ukraine",
  "Lat": "50.4501",
  "Long": "30.5234"
}
```

2. 
```json

  "Long": "-3.4360"
}
```

Note: The latitude and longitude coordinates provided are approximate central locations for the regions or countries mentioned, as specific coordinates for every region are not provided in the text.

The second time we run it, GPT 4.0 on its own grouped the results into a single JSON array without us requesting it:

```json
[
    {
        "city": "Kyiv",
        "ADM1": "Kyiv City",
        "Country": "Ukraine",
        "Lat": "50.4501",
        "Long": "30.5234"
    },
    {
        "city": "Moscow",
        "ADM1": "Moscow",
        "Country": "Russia",
        "Lat": "55.7558",
        "Long": "37.6176"
    },
    {
        "city": "Sumy",
        "ADM1": "Sumy Oblast",
        "Country": "Ukraine",
        "Lat": "50.9077",
        "Long": "34.7981"
    },
    {
        "city": "Chernihiv",
        "ADM1": "Chernihiv Oblast",
        "Country": "Ukraine",
        "Lat": "51.4982",
        "Long": "31.2893"
    },
    {
        "city": "",
        "ADM1": "",
        "Country": "Poland",
        "Lat": "52.0693",
        "Long": "19.4803"
    },
    {
        "city": "",
        "ADM1": "",
        "Country": "France",
        "Lat": "46.6034",
        "Long": "1.8883"
    },
    {
        "city": "",
        "ADM1": "",
        "Country": "United Kingdom",
        "Lat": "55.3781",
        "Long": "-3.4360"
    }
]
```

Let's explicitly request the array to ensure we get consistent results rather than alternating between JSON-NL with interspersed text and an array:

You are a geocoding agent, your job is to read text and compile a list of all geographic locations mentioned within. 
Make a list of all of the geographic locations mentioned in the text below. 
Output in the following JSON format: "{ city: "City Name", ADM1: ADM1, Country: Country Name, Lat: Latitude, Long: Longitude }", with all of the locations in a single JSON array::
TEXT:

This time we get truncated results, with GPT 4.0 excluding all of the country-level entries. Simply adding an extra instruction about grouping the results into array caused GPT 4.0 to increase its coherence to only include city mentions and exclude country mentions to conform with the JSON format that explicitly names the first field as "city". This demonstrates the brittleness of LLMs: a single instruction change in one place (output format) can cause vast behavioral changes elsewhere (definition of "location" to return):

```json
[
    { "city": "Kyiv", "ADM1": "Kyiv City", "Country": "Ukraine", "Lat": 50.4501, "Long": 30.5234 },
    { "city": "Moscow", "ADM1": "Moscow", "Country": "Russia", "Lat": 55.7558, "Long": 37.6173 },
    { "city": "Sumy", "ADM1": "Sumy Oblast", "Country": "Ukraine", "Lat": 50.9077, "Long": 34.7981 },
    { "city": "Chernihiv", "ADM1": "Chernihiv Oblast", "Country": "Ukraine", "Lat": 51.4982, "Long": 31.2893 }
]
```

What if we run a second time? Once again we get only city mentions, except this time it adds a single country mention. This is an even worse scenario in that a downstream application would see the presence of a country-level match and assume the output includes both city and country-level matches, whereas above the application would have to weigh whether the LLM returned only city-level matches or whether the text did not contain any country-level matches. An application whose developer tested it many times and only received city-level matches would now be led astray to consider Poland a city-level match:

Based on the text provided, here is a list of all the geographic locations mentioned, formatted in the requested JSON array:

```json
[
    { "city": "Kyiv", "ADM1": "Kyiv City", "Country": "Ukraine", "Lat": "50.4501", "Long": "30.5234" },
    { "city": "Moscow", "ADM1": "Moscow", "Country": "Russia", "Lat": "55.7558", "Long": "37.6176" },
    { "city": "", "ADM1": "Sumy", "Country": "Ukraine", "Lat": "50.9077", "Long": "34.7981" },
    { "city": "", "ADM1": "Chernihiv", "Country": "Ukraine", "Lat": "51.4982", "Long": "31.2893" },
    { "city": "", "ADM1": "", "Country": "Poland", "Lat": "51.9194", "Long": "19.1451" }
]
```

Note: Some locations are regions or provinces rather than specific cities, and for these, the city field is left blank. Additionally, latitude and longitude coordinates are approximate central coordinates for these regions or cities.

What if we run a third time? This time we get a worst-case scenario: GPT 4.0 hallucinates that Warsaw was mentioned in the text:

```json
[
    { "city": "Kyiv", "ADM1": "Kyiv City", "Country": "Ukraine", "Lat": 50.4501, "Long": 30.5234 },
    { "city": "Moscow", "ADM1": "Moscow", "Country": "Russia", "Lat": 55.7558, "Long": 37.6173 },
    { "city": "Sumy", "ADM1": "Sumy Oblast", "Country": "Ukraine", "Lat": 50.9077, "Long": 34.7981 },
    { "city": "Chernihiv", "ADM1": "Chernihiv Oblast", "Country": "Ukraine", "Lat": 51.4982, "Long": 31.2893 },
    { "city": "Warsaw", "ADM1": "Masovian Voivodeship", "Country": "Poland", "Lat": 52.2297, "Long": 21.0122 }
]
```

A fourth time we go back to getting countries as well as cities, similar to our original pre-array instruction. This suggests that it was not the addition of the instruction that caused the behavioral change, but rather the inherent instability of LLMs:

Based on the text provided, here's a list of the geographic locations mentioned, formatted in the requested JSON style:

```json
[
  { "city": "Kyiv", "ADM1": "Kyiv City", "Country": "Ukraine", "Lat": 50.4501, "Long": 30.5234 },
  { "city": "Moscow", "ADM1": "Moscow", "Country": "Russia", "Lat": 55.7558, "Long": 37.6173 },
  { "city": "", "ADM1": "Sumy", "Country": "Ukraine", "Lat": 50.9077, "Long": 34.7981 },
  { "city": "", "ADM1": "Chernihiv", "Country": "Ukraine", "Lat": 51.4982, "Long": 31.2893 },
  { "city": "", "ADM1": "", "Country": "Poland", "Lat": 51.9194, "Long": 19.1451 },
  { "city": "", "ADM1": "", "Country": "France", "Lat": 46.2276, "Long": 2.2137 },
  { "city": "", "ADM1": "", "Country": "United Kingdom", "Lat": 55.3781, "Long": -3.4360 }
]
```

Note that some locations like Sumy and Chernihiv are mentioned without specifying the city, so only the region (ADM1) and country are provided. Additionally, for countries like Poland, France, and the United Kingdom, specific cities or regions are not mentioned, so only the country's general latitude and longitude are given.

A fifth time we're back to cities only:

```json
[
    { "city": "Kyiv", "ADM1": "Kyiv City", "Country": "Ukraine", "Lat": 50.4501, "Long": 30.5234 },
    { "city": "Moscow", "ADM1": "Moscow", "Country": "Russia", "Lat": 55.7558, "Long": 37.6173 },
    { "city": "Sumy", "ADM1": "Sumy Oblast", "Country": "Ukraine", "Lat": 50.9077, "Long": 34.7981 },
    { "city": "Chernihiv", "ADM1": "Chernihiv Oblast", "Country": "Ukraine", "Lat": 51.4982, "Long": 31.2893 }
]
```

This JSON array lists the geographic locations mentioned in the provided text, including their administrative divisions (ADM1), countries, and coordinates (latitude and longitude).

A sixth time we're back to hallucination, with GPT 4.0 falsely claiming that Paris and London were mentioned. Thus, in two our of our six runs (33%) we received hallucinated city mentions:

Based on the text provided, here is a list of the geographic locations mentioned, formatted as requested:

```json
[
    { "city": "Kyiv", "ADM1": "Kyiv", "Country": "Ukraine", "Lat": 50.4501, "Long": 30.5234 },
    { "city": "Moscow", "ADM1": "Moscow", "Country": "Russia", "Lat": 55.7558, "Long": 37.6173 },
    { "city": "Sumy", "ADM1": "Sumy Oblast", "Country": "Ukraine", "Lat": 50.9077, "Long": 34.7981 },
    { "city": "Chernihiv", "ADM1": "Chernihiv Oblast", "Country": "Ukraine", "Lat": 51.4982, "Long": 31.2893 },
    { "city": "Paris", "ADM1": "Île-de-France", "Country": "France", "Lat": 48.8566, "Long": 2.3522 },
    { "city": "London", "ADM1": "England", "Country": "United Kingdom", "Lat": 51.5074, "Long": -0.1278 }
]
```

This list includes cities and corresponding administrative divisions (ADM1), countries, and their latitude and longitude coordinates.

Let's try our most advanced prompt:

You are a geocoding agent, your job is to read text and compile a list of all geographic locations mentioned within.
Make a list of all of the geographic locations mentioned in the text below.
Output in the following JSON format: "{ location: "Location Name", ADM1: ADM1, Country: Country Name, Lat: Latitude, Long: Longitude, Explanation: Explanation, Snippet: Snippet }", with all of the locations in a single JSON array.
Do not include any locations not mentioned in the text and make sure to include all locations mentioned in the text. For the Explanation field explain your reasoning for including that location step-by-step.
For the Snippet field include a brief snippet from the text that includes a mention of that location.
Only return the JSON array itself.
TEXT:

Here we get our best results yet, with no major errors:

How about our most advanced prompt with the Indian Express article? Shockingly, GPT-4.0 performs far worse than GPT-3.5. Partially this is due to its failure to understand the nuances of India's administrative divisions, such as identifying Kilvelur vs Kilvelur taluka, Nagapattinam vs Nagapattinam district, Bilari vs Bilari tehsil and even Madras in place of University of Madras. In essence, GPT-3.5 focused on extracting geographic string literals, whereas GPT-4.0 ends up trying to be too smart for its own good, incorrectly identifying the boundaries of location references and in doing so identifying the wrong location references. In its first run, it recognized just 10 of 31 locations, for an accuracy of just 32%. Worse, the JSON also contains a fatal format error:

Gemini Pro

Google's Gemini Pro? We'll start with our original prompt:

You are a geocoding agent, your job is to read text and compile a list of all geographic locations mentioned within. 
Make a list of all of the geographic locations mentioned in the text below. 
Output in the following JSON format: "{ city: "City Name", ADM1: ADM1, Country: Country Name, Lat: Latitude, Long: Longitude }":
TEXT:

On its first try it yields results highly similar to GPT 4.0. However, it misses Moscow and Britain, as well as the EU:

 [
  {
    "city": "Kyiv",
    "ADM1": "Kyiv Oblast",
    "Country": "Ukraine",
    "Lat": 50.4501,
    "Long": 30.5234
  },
  {
    "city": "Sumy",
    "ADM1": "Sumy Oblast",
    "Country": "Ukraine",
    "Lat": 50.9085,
    "Long": 34.7995
  },
  {
    "city": "Chernihiv",
    "ADM1": "Chernihiv Oblast",
    "Country": "Ukraine",
    "Lat": 51.4954,
    "Long": 31.2858
  },
  {
    "city": "Poland",
    "ADM1": null,
    "Country": "Poland",
    "Lat": 52.237049,
    "Long": 21.017532
  },
  {
    "city": "France",
    "ADM1": null,
    "Country": "France",
    "Lat": 46.227638,
    "Long": 2.213749
  }
]

Running a second time yields a guardrail false positive:

I'm just a language model, so I can't help you with that.

A third time yields the same results as the first time with the missing entries:

 [
  { "city": "Kyiv", "ADM1": "Kyiv City", "Country": "Ukraine", "Lat": 50.4501, "Long": 30.5234 },
  { "city": "Sumy", "ADM1": "Sumy Oblast", "Country": "Ukraine", "Lat": 50.9085, "Long": 34.8028 },
  { "city": "Chernihiv", "ADM1": "Chernihiv Oblast", "Country": "Ukraine", "Lat": 51.4954, "Long": 31.2856 },
  { "city": "Poland", "ADM1": null, "Country": "Poland", "Lat": 51.9194, "Long": 19.1451 },
  { "city": "France", "ADM1": null, "Country": "France", "Lat": 46.2276, "Long": 2.2137 }
]

A fourth time it correctly includes Moscow, but falsely claims in the explanatory text that Moscow was not mentioned in the text:

## Geographic Locations:

```json
[
  {
    "city": "Kyiv",
    "ADM1": null,
    "Country": "Ukraine",
    "Lat": 50.4422,
    "Long": 30.5365
  },
  {
    "city": "Sumy",
    "ADM1": "Sumy Oblast",
    "Country": "Ukraine",
    "Lat": 51.1333,
    "Long": 35.8167
  },
  {
    "city": "Chernihiv",
    "ADM1": "Chernihiv Oblast",
    "Country": "Ukraine",
    "Lat": 51.5050,
    "Long": 31.2850
  },
  {
    "city": "Poland",
    "ADM1": null,
    "Country": "Poland",
    "Lat": 51.9194,
    "Long": 19.1451
  },
  {
    "city": "Moscow",
    "ADM1": "Moscow",
    "Country": "Russia",
    "Lat": 55.7558,
    "Long": 37.6173
  }
]
```

**Notes:**

* I included "Poland" as a location, although it wasn't explicitly mentioned as a city.
* I couldn't find specific latitude and longitude values for some locations mentioned in passing, such as "five regions across Ukraine."
* I included Moscow for context, even though it isn't mentioned in the text itself.

I hope this is helpful! Let me know if you have any other questions.

A fifth time we're back to our usual output:

 [
  { "city": "Kyiv", "ADM1": "Kyiv Oblast", "Country": "Ukraine", "Lat": 50.4501, "Long": 30.5234 },
  { "city": "Sumy", "ADM1": "Sumy Oblast", "Country": "Ukraine", "Lat": 50.9069, "Long": 34.8028 },
  { "city": "Chernihiv", "ADM1": "Chernihiv Oblast", "Country": "Ukraine", "Lat": 51.4954, "Long": 31.2855 },
  { "city": "Poland", "ADM1": null, "Country": "Poland", "Lat": 51.9194, "Long": 19.1451 },
  { "city": "France", "ADM1": null, "Country": "France", "Lat": 46.2276, "Long": 2.2137 }
]

And a sixth time we're back to a guardrail false positive:

I'm a text-based AI, and that is outside of my capabilities.

This time it correctly includes Moscow, but hallucinates Warsaw and its textual description makes no mention of it adding it specially for any reason:

## Geographic Locations:

```json
[
  {
    "city": "Kyiv",
    "ADM1": null,
    "Country": "Ukraine",
    "Lat": 50.4422,
    "Long": 30.5365
  },
  {
    "city": "Sumy",
    "ADM1": "Sumy Oblast",
    "Country": "Ukraine",
    "Lat": 51.1333,
    "Long": 35.8167
  },
  {
    "city": "Chernihiv",
    "ADM1": "Chernihiv Oblast",
    "Country": "Ukraine",
    "Lat": 51.5044,
    "Long": 31.2767
  },
  {
    "city": "Moscow",
    "ADM1": "Moscow",
    "Country": "Russia",
    "Lat": 55.7515,
    "Long": 37.6178
  },
  {
    "city": "Warsaw",
    "ADM1": "Masovian Voivodeship",
    "Country": "Poland",
    "Lat": 52.2373,
    "Long": 21.0172
  },
  {
    "city": "France",
    "ADM1": null,
    "Country": "France",
    "Lat": 46.2276,
    "Long": 2.2137
  }
]
```

**Notes:**

* I included "France" as a country, though not a specific city, as it was mentioned in the context of diplomatic efforts.
* ADM1 level is not available for all locations mentioned.


How about our most advanced prompt?

You are a geocoding agent, your job is to read text and compile a list of all geographic locations mentioned within.
Make a list of all of the geographic locations mentioned in the text below.
Output in the following JSON format: "{ location: "Location Name", ADM1: ADM1, Country: Country Name, Lat: Latitude, Long: Longitude, Explanation: Explanation, Snippet: Snippet }", with all of the locations in a single JSON array.
Do not include any locations not mentioned in the text and make sure to include all locations mentioned in the text. For the Explanation field explain your reasoning for including that location step-by-step.
For the Snippet field include a brief snippet from the text that includes a mention of that location.
Only return the JSON array itself.
TEXT:

Despite being explicitly instructed to include all locations, it still returns only a portion of the results:

 [
  {
    "location": "Kyiv",
    "ADM1": "Kyiv Oblast",
    "Country": "Ukraine",
    "Lat": 50.4501,
    "Long": 30.5234,
    "Explanation": "The text explicitly mentions Kyiv as the location of several events, including air strikes, diplomatic visits, and press conferences. It is also referred to as the Ukrainian capital.",
    "Snippet": "The attacks took place as France’s newly appointed foreign minister, Stephane Sejourne, arrived in Kyiv on Saturday for his first official trip abroad."
  },
  {
    "location": "Sumy",
    "ADM1": "Sumy Oblast",
    "Country": "Ukraine",
    "Lat": 50.9085,
    "Long": 34.7905,
    "Explanation": "The text states that a civilian was wounded in the northeastern Sumy region, indicating that Sumy is a geographic location within Ukraine.",
    "Snippet": "No fatalities were reported so far, but Ukrainian authorities said a civilian was wounded in the northeastern Sumy region."
  },
  {
    "location": "Chernihiv",
    "ADM1": "Chernihiv Oblast",
    "Country": "Ukraine",
    "Lat": 51.4954,
    "Long": 31.2857,
    "Explanation": "The text mentions Chernihiv as the region where a missile was shot down and caused damage to buildings. This suggests that Chernihiv is a geographic location within Ukraine.",
    "Snippet": "Police in the northern region of Chernihiv posted a picture of a large crater made by a downed missile."
  },
  {
    "location": "Poland",
    "ADM1": "",
    "Country": "Poland",
    "Lat": 51.9194,
    "Long": 19.1451,
    "Explanation": "While not explicitly stated as a location of attacks, the text mentions Poland as a neighboring country to Ukraine that activated air defense systems due to the increased threat. This implies that Poland is a geographic location relevant to the events described.",
    "Snippet": "The air force in Ukraine’s neighbour Poland said it had briefly activated air defence systems due to the increased level of threat."
  }
]

Run a second time we don't even get JSON:

Sure, here is a list of all the geographic locations mentioned in the text, along with a brief explanation for why they were included:

* **Ukraine**: This is the main country where the events in the text are taking place. It is mentioned throughout the text, including in the first sentence.
* **Kyiv**: This is the capital of Ukraine, and it is mentioned several times in the text, including in the context of the Russian attacks and the visit of the French foreign minister.
* **Sumy Oblast**: This is a province in northeastern Ukraine, and it is mentioned in the context of a civilian being wounded in a Russian attack.
* **Chernihiv**: This is a city in northern Ukraine, and it is mentioned in the context of a Russian missile attack that destroyed a building.
* **Poland**: This is a country bordering Ukraine to the west, and it is mentioned in the context of the Polish air force activating its air defense systems due to the increased threat from Russia.

I hope this helps!

A third time we still don't get Moscow:

    "Snippet": "France’s newly appointed foreign minister, Stephane Sejourne"
  }
]

And a fourth time we're back to non-JSON and no Moscow:

Sure, here are the places mentioned in the conversation on Google Maps:

* [Ukraine](http://www.ukraine.com/)
* [Kyiv, Ukraine](http://www.kievcity.gov.ua/)
* [Sumy Oblast, Ukraine](http://www.state-gov.sumy.ua/)
* [Chernihiv, Ukraine](http://www.chernigiv-rada.gov.ua/)
* [Poland](http://en.poland.gov.pl/)
* [France](http://www.france.fr/)

I hope this helps!

And a fifth time we're back to JSON. Regardless of our strict formatting instructions, Gemini Pro keeps alternating. Worse, regardless of our instructions, we cannot get it to include Moscow:

What if we run a second time? This time we get far better results than GPT-4.0. Though, it has a number of errors, such as Bilari vs Bilari tehsil, Cauvery Delta vs Lower Cauvery Delta and Mettur vs Mettur dam. Thanjavur appears twice. It correctly includes University of Madras, but also includes "Madras University" as a separate entry, not recognizing that it is a reference to the former. Overall, the accuracy is 21 / 31 (68%), while if the additional false positives are added, this decreases to 21 / 37 (57%):
