Event detector

This module contains the EventDetection class, which is aimed to generate events and their connections based on the application of semantic clustering method (BERTopic) on the texts in the context of an urban spatial model.

The EventDetection class has the following methods:

@method:_get_roads: Get the road network of a city as road links and roads.

@method:_get_buildings: Get the buildings of a city as a GeoDataFrame.

@method:_collect_population: Collect population data for each object (building, street, link).

@method:_preprocess: Preprocess the data.

class soika.src.risks.event_detector.EventDetection

This class is aimed to generate events and their connections. It is based on the application of semantic clustering method (BERTopic) on the texts in the context of urban spatial model

run(target_texts: GeoDataFrame, filepath_to_population: str, city_name: str, city_crs: int, min_event_size: int)

Returns a GeoDataFrame of events, a GeoDataFrame of connections between events, and a GeoDataFrame of messages.
