Enterprise Search with AI for Complex Research Queries

Searching large natural language research repositories and verifying answers against their sources: HMS developed an AI-powered enterprise search solution based on a RAG system for a global chemical company.

Management Summary

The solution makes internal research data, patents, external literature, and other knowledge sources accessible via natural-language queries. The RAG chatbot identifies relevant content from texts, tables, and images. Subject matter experts receive generated responses with references to the underlying sources.

Project Goal

Address complex research questions via natural-language queries on large research datasets

Key Core Functions

  • Natural-language search across internal research data, patents, external literature, and other sources
  • RAG-based identification of relevant content from text, tables, and images
  • Generation of answers with source references to provide a subject-matter context for the results

In this project, retrieval, source attribution, and subject-matter verifiability had to work together. Only then can an LLM be truly useful for research questions.

The Starting Point

The global chemical company had extensive research databases that had grown over the years. Subject matter experts had to find relevant information from internal research data, patents, external literature, and other sources, and contextualize it within their field.

Traditional search approaches were insufficient for many complex research questions. The queries were specific, context-dependent, and often could not be addressed using individual search terms. What was needed was an AI-powered enterprise search solution capable of processing natural language and making large datasets accessible for research.

The HMS Solution

Enterprise Search with AI Based on a RAG System

HMS developed a RAG-based chatbot that allows subject matter experts to search for research information using natural language queries.

Retrieval from Research Sources

The solution uses retrieval-augmented generation to identify relevant content from the connected sources. It was initially based on approximately 500,000 pieces of internal research data.

Processing Different Data Formats

The system was originally designed for text data and later expanded to include tables and images. This allows different forms of information to be included in the search.

Source-Based Answers

Answer generation is designed to be source-based. Subject-matter experts not only receive a generated answer but can also verify the technical basis using referenced content.

Extensible Source Integration

Over the course of the project, the solution was expanded to include the company’s own patents, 20 million documents, external literature, and other internal and external sources. GraphQL and Structured Output support structured integration and further processing.

Customer Benefits

Making research knowledge more accessible.

The RAG-based chatbot helps researchers search large internal and external knowledge bases using natural language, identify relevant content more quickly, and verify answers against sources.

More precise

Relevant excerpts instead of search results

The solution provides relevant document excerpts for complex research questions, rather than simply guiding users through long lists of results.

More understandable

Citation for each answer

Answers are provided with references to the underlying sources. Researchers can verify the factual basis directly.

Integratable

Integration into the existing search function

The generative AI core was integrated into the client’s existing search infrastructure and was able to be expanded to include additional sources, document collections, and data formats.

Our Strengths, Your Benefits

RAG for Research Data

HMS combines AI engineering, data architecture, and implementation experience in complex enterprise environments. In this project, the focus was on making large research datasets accessible via natural language and verifiable by subject matter experts.

What You Can Expect from HMS

HMS helps you assess AI-powered search solutions from a business perspective, implement them technically, and integrate them into existing data and search environments.

  • Implementation of a RAG-based chatbot system for large research datasets
  • Integration of internal and external knowledge sources
