Chat with your Device

Technicians on-site at medical and operational equipment often face the challenge of quickly finding relevant information from extensive user manuals. Manually searching through documentation costs time and is error-prone.

The Concept

The concept of this proof of concept: A chat interface through which technicians simply enter the device type and receive relevant information about the device – without manual document search. In addition to internal documentation, a web search is offered to also include external information sources.

Technical Implementation

The technical implementation is based on LangChain as an agent framework. A dataset of approximately 6,000 documents – primarily user manuals – was embedded and stored in a Milvus Vector Database. The agent orchestrates various tools: Semantic Search on the embeddings, web search for supplementary information and database queries.

Source Referencing

A central feature is the consistent source referencing: Every answer contains references that should be verified – for example, links to the user manual including page number or links to external websites. This ensures that technicians can verify the information before taking action.
