compass.extraction.wind.parse.StructuredWindPermittedUseDistrictsParser#

class StructuredWindPermittedUseDistrictsParser(llm_service, usage_tracker=None, **kwargs)[source]#

Bases: StructuredWindParser

LLM permitted use districts scraping utility

Purpose:

Extract structured ordinance data from text.

Responsibilities:

  1. Extract ordinance values into structured format by executing a decision-tree-based chain-of-thought prompt on the text for each value to be extracted.

Key Relationships:

Uses a StructuredLLMCaller for LLM queries and multiple AsyncDecisionTree instances to guide the extraction of individual values.

Parameters:

  • llm_service (compass.services.base.Service) – LLM service used for queries.

  • usage_tracker (compass.services.usage.UsageTracker, optional) – Optional tracker instance to monitor token usage during LLM calls. By default, None.

  • **kwargs – Keyword arguments to be passed to the underlying service processing function (i.e. llm_service.call(**kwargs)). Should not contain the following keys:

    • usage_tracker

    • usage_sub_label

    • messages

    These arguments are provided by this caller object.
