An Agent Framework for Real-Time Financial Information Searching with Large Language Models

TL;DR

FinSearch is an innovative agent framework that enhances real-time financial information retrieval by integrating large language models with dynamic, context-aware search and synthesis capabilities tailored for financial data sources.

Contribution

The paper introduces FinSearch, a novel multi-component agent system that combines LLMs with adaptive, temporally-aware search strategies for improved financial information retrieval.

Findings

Outperforms traditional search methods in financial data retrieval accuracy.

Effectively adapts to dynamic market conditions through its query rewriter.

Achieves coherent and contextually relevant responses in real-time financial scenarios.

Abstract

Financial decision-making requires processing vast amounts of real-time information while understanding their complex temporal relationships. While traditional search engines excel at providing real-time information access, they often struggle to comprehend sophisticated user intentions and contextual nuances. Conversely, Large Language Models (LLMs) demonstrate reasoning and interaction capabilities but may generate unreliable outputs without access to current data. While recent attempts have been made to combine LLMs with search capabilities, they suffer from (1) restricted access to specialized financial data, (2) static query structures that cannot adapt to dynamic market conditions, and (3) insufficient temporal awareness in result generation. To address these challenges, we present FinSearch, a novel agent-based search framework specifically designed for financial applications that interface with diverse financial data sources including market, stock, and news data. Innovatively, FinSearch comprises four components: (1) an LLM-based multi-step search pre-planner that decomposes user queries into structured sub-queries mapped to specific data sources through a graph representation; (2) a search executor with an LLM-based adaptive query rewriter that executes the searching of each sub-query while dynamically refining the sub-queries in its subsequent node based on intermediate search results; (3) a temporal weighting mechanism that prioritizes information relevance based on the deduced time context from the user's query; (4) an LLM-based response generator that synthesizes results into coherent, contextually appropriate outputs. To evaluate FinSearch, we construct FinSearchBench-24, a benchmark of 1,500 four-choice questions across the stock market, rate changes, monetary policy, and industry developments spanning from June to October 2024.
