# Places Dataset

### Dataset Summary

This dataset contains information of roughly 70,000 places with associated metadata including locations, attribution tags, and some contact details. The data includes geographic coordinates, place descriptions, categorization through attribution tags, and some social media presence information.

### LLM Applications

This dataset is particularly valuable for training and fine-tuning Large Language Models (LLMs) for geospatial understanding:

- **Geospatial Question Answering**: Train LLMs to answer location-based queries like "What coffee shops are near Central Park?" or "Find museums in Paris"
- **Location-Aware Text Generation**: Enable LLMs to generate contextually relevant descriptions that incorporate local geography, landmarks, and spatial relationships
- **Address Parsing and Normalization**: The cleaned address formats provide training data for LLMs to understand and standardize various address formats from different countries
- **Multilingual Geographic Entity Recognition**: With places from multiple countries, LLMs can learn to recognize and disambiguate location names across languages
- **Spatial Reasoning**: Train models to understand spatial relationships, distances, and geographic hierarchies (neighborhood → city → state → country)
- **Travel and Tourism Assistants**: Build LLMs that can provide recommendations based on location, tags, and place descriptions
- **Local Business Understanding**: Help LLMs understand business categories, operating contexts, and location-specific services

### Supported Tasks and Leaderboards

This dataset can be used for various tasks including:
- **Location-based recommendation systems**
- **Geographic information retrieval**
- **Place categorization and tagging**
- **Spatial analysis and clustering**
- **Geospatial NLP and language understanding**
- **Cross-lingual location entity linking**

### Languages

The dataset is primarily in English, with place names and descriptions being in English.

```

### Working with the Data

#### LLM-Specific Examples

##### Training Data Preparation for Geospatial QA
```python
# Prepare training examples for location-based Q&A
def create_qa_examples(dataset):
    examples = []
    for place in dataset:
        # Create various question-answer pairs
        examples.extend([
            {
                "question": f"What is the address of {place['name']}?",
                "answer": place['address_formatted']
            },
            {
                "question": f"Where is {place['name']} located?",
                "answer": f"{place['name']} is located at {place['address']} in {place['locality']}, {place['administrative_area']}, {place['country']}."
            },
            {
                "question": f"What type of place is {place['name']}?",
                "answer": f"{place['name']} is a {place['primary_tag_name']}." if place['primary_tag_name'] else f"Information about the type of {place['name']} is not available."
            }
        ])
        
        if place['description']:
            examples.append({
                "question": f"Tell me about {place['name']}",
                "answer": place['description']
            })
    
    return examples

# Load denormalized data for easy access to all fields
dataset = load_dataset("path/to/places_dataset.py", "denormalized")['train']
qa_examples = create_qa_examples(dataset)
```

##### Spatial Context Generation
```python
# Generate spatial context descriptions for LLM training
def generate_spatial_context(place, nearby_places):
    context = f"{place['name']} is located at {place['address']} in {place['locality']}."
    
    if nearby_places:
        context += f" Nearby places include: "
        nearby_names = [f"{p['name']} ({p['distance_km']:.1f}km)" for p in nearby_places[:5]]
        context += ", ".join(nearby_names) + "."
    
    if place['primary_tag_name']:
        context += f" It is categorized as a {place['primary_tag_name']}."
    
    return context

# Example usage
center_place = dataset[0]
nearby = find_nearby_places(dataset, center_place['latitude'], center_place['longitude'], 2)
spatial_description = generate_spatial_context(center_place, nearby)
```

#### Basic Place Information
```python
# Load places with their basic information
places = load_dataset("path/to/places_dataset.py", "place")['train']

# Access place data
for place in places.select(range(5)):
    print(f"Name: {place['name']}")
    print(f"Address: {place['address_formatted']}")
    print(f"Locality: {place['locality']}, {place['administrative_area']}")
    print("---")
```

#### Using the Denormalized View (Recommended)
```python
# Load denormalized data - includes places, locations, primary tags, and contacts
dataset = load_dataset("path/to/places_dataset.py", "denormalized")['train']

# Now you have everything in one table!
for place in dataset.select(range(5)):
    print(f"Name: {place['name']}")
    print(f"Location: {place['latitude']}, {place['longitude']}")
    print(f"Primary Tag: {place['primary_tag_name']}")
    print(f"Website: {place['website']}")
    print("---")

# Easy filtering with coordinates
import pandas as pd
df = pd.DataFrame(dataset)
# Find verified places with coordinates
verified_with_coords = df[
    (df['verified'] == True) & 
    (df['latitude'].notna()) & 
    (df['longitude'].notna())
]
```

#### Joining Tables (Places with Locations)
```python
import pandas as pd

# Load as pandas DataFrames for easier joining
places_df = pd.DataFrame(places)
locations = load_dataset("path/to/places_dataset.py", "location")['train']
locations_df = pd.DataFrame(locations)

# Join places with their locations
places_with_coords = places_df.merge(
    locations_df, 
    left_on='location_id', 
    right_on='id', 
    suffixes=('', '_loc')
)

# Filter places in a specific area (e.g., within a bounding box)
def filter_by_bbox(df, min_lat, max_lat, min_lon, max_lon):
    return df[
        (df['latitude'] >= min_lat) & 
        (df['latitude'] <= max_lat) &
        (df['longitude'] >= min_lon) & 
        (df['longitude'] <= max_lon)
    ]

# Example: Find places in San Francisco area
sf_places = filter_by_bbox(places_with_coords, 37.7, 37.8, -122.5, -122.4)
```

#### Working with Tags
```python
# Load all necessary tables
places_df = pd.DataFrame(load_dataset("path/to/places_dataset.py", "place")['train'])
tags_df = pd.DataFrame(load_dataset("path/to/places_dataset.py", "tag")['train'])
place_tags_df = pd.DataFrame(load_dataset("path/to/places_dataset.py", "place_tag")['train'])

# Get all tags for a specific place
def get_place_tags(place_id):
    # Find all tag relationships for this place
    tag_ids = place_tags_df[place_tags_df['place_id'] == place_id]['tag_id']
    # Get tag details
    return tags_df[tags_df['id'].isin(tag_ids)]

# Find all places with a specific tag
def find_places_by_tag(tag_name):
    # Find the tag
    tag = tags_df[tags_df['name'] == tag_name]
    if tag.empty:
        return pd.DataFrame()
    
    tag_id = tag.iloc[0]['id']
    # Find all places with this tag
    place_ids = place_tags_df[place_tags_df['tag_id'] == tag_id]['place_id']
    return places_df[places_df['id'].isin(place_ids)]

# Example: Find all coffee shops
coffee_shops = find_places_by_tag('Coffee Shop')
```

### Using the Alternative Loading Function

```python
from places_dataset import load_places_as_dict

# Load all tables as a dictionary
data = load_places_as_dict('/path/to/data/directory')

# Access individual tables
places = data['place']
locations = data['location']
tags = data['tag']
```

### Working with Geospatial Data

#### Coordinate System Information
- **Latitude/Longitude**: WGS84 (EPSG:4326) - Standard GPS coordinates
- **Geom column**: Projected geometry, useful for visualization and area calculations
- **Geog column**: Geography type for accurate distance and spatial calculations

#### Example: Distance Calculations
```python
import math

def haversine_distance(lat1, lon1, lat2, lon2):
    """Calculate distance between two points on Earth in kilometers."""
    R = 6371  # Earth's radius in kilometers
    
    lat1, lon1, lat2, lon2 = map(math.radians, [lat1, lon1, lat2, lon2])
    dlat = lat2 - lat1
    dlon = lon2 - lon1
    
    a = math.sin(dlat/2)**2 + math.cos(lat1) * math.cos(lat2) * math.sin(dlon/2)**2
    c = 2 * math.asin(math.sqrt(a))
    
    return R * c

# Find places near a specific coordinate
def find_nearby_places(places_with_coords, center_lat, center_lon, radius_km):
    nearby = []
    for _, place in places_with_coords.iterrows():
        distance = haversine_distance(
            center_lat, center_lon,
            place['latitude'], place['longitude']
        )
        if distance <= radius_km:
            nearby.append({**place.to_dict(), 'distance_km': distance})
    
    return pd.DataFrame(nearby).sort_values('distance_km')

# Example: Find places within 5km of a location
nearby = find_nearby_places(places_with_coords, 37.7749, -122.4194, 5)
```
