Introduction

Picture this: You go to a library to borrow a book. You look up the book title or author name on the repository, find the code, and go to the relevant section and aisle to retrieve the book. Easy, right?

Now, imagine you are a biomedical scientist on the brink of making a significant scientific discovery. You just need a key piece of information to tie up loose ends, and it is critical that you obtain that information as soon as possible, before the thought process is lost or interrupted. You fire up the computer, wait for your datasets to load, start coding a query to obtain the necessary information, have to invariably take a couple of pitstops to solve a few issues with your code, and by the time you have figured out the code to ask the query, you have forgotten why you were looking for this information in the first place.

In today’s fast-paced world of biomedical research, the sheer volume and complexity of data have reached unprecedented levels. While this data holds tremendous potential for driving breakthroughs, researchers face significant challenges in accessing and analyzing it efficiently. Traditional methods of data retrieval are often cumbersome, requiring specialized expertise and significant time investments.

Enter AI-powered chatbots: a modern solution for researchers to interact with data.

Challenges in Biomedical Data Retrieval

Our client, a leading pharmaceutical company, faced challenges with regards to fast and timely data retrieval. Their objective was clear: streamline data retrieval to enhance researcher productivity. The obstacles facing them were two-pronged: 1) Information overload and 2) lack of coding expertise.

Information Overload

Biomedical research generates vast quantities of data from diverse sources, including public repositories, clinical trials, new research publications, and experimental results. This data explosion can be an overwhelming workspace for researchers to navigate. Key challenges include:

• Fragmentation: Data is stored across multiple platforms in different incompatible formats.
• Lack of Structure: Unstructured and semi-structured data make analysis difficult and time-consuming.
• Volume: The sheer scale of available information demands advanced tools for filtering relevant datasets.

These factors result in time-consuming manual searches, like looking for a single book in a massive, disorganized library without proper codes or search engines. Fragmented biomedical data repositories impede productivity and increase the risk of missing data and delaying insights. For example, a researcher seeking gene expression data from a niche dataset may spend hours manually combing through unstructured repositories. This inefficiency directly impacts productivity and delays the research pipeline.

Lack of Coding Expertise

While bioinformatics has made significant strides in analyzing large datasets, not all researchers possess coding skills. Reliance on bioinformatics teams to write complex queries creates bottlenecks, delaying data access and slowing discovery processes. Researchers need intuitive tools that eliminate the dependency on coding without compromising analytical power.

The gap is particularly apparent in multi-disciplinary teams where biologists, chemists, and clinicians need access to data without technical barriers. The inability to engage with data independently hampers progress and reduces productivity, while also increasing frustration and dissatisfaction among researchers.

The Solution

Concept and Functionality

To address these challenges, we developed an AI-powered chatbot powered by large language models (LLMs), a solution that acts as the equivalent of a knowledgeable librarian who can instantly guide you to the exact book or resource, whenever you need it. This tool allows researchers to retrieve and analyze data using natural language queries. By combining domain-specific data harmonization with retrieval-augmented generation (RAG), the chatbot delivers accurate, contextually relevant results.

The chatbot functions as a virtual assistant customized for biomedical research, allowing users to bypass complex query writing. Instead of struggling with technical syntax and code trouble-shooting, researchers can ask questions like, “What are the top 10 upregulated genes in lung cancer datasets?” and receive precise, usable responses within seconds.

Key Features

• Harmonized Data: We used our proprietary harmonization engine to ensure datasets were AI-ready and structured for effective querying. Multi-modal data, such as data from slide decks, research papers, experiments, and public repositories, were initially harmonized, with consistent notations, symbols, and terminologies. Embedding models were employed to convert these harmonized datasets into numerical vector representations. These embeddings were then stored in vector stores, enabling efficient indexing and retrieval of data. Together, this foundation allowed the chatbot to deliver accurate and contextually relevant responses by using these AI-enhanced datasets.
  
  
• Biological Context Integration: The chatbot included user intent detection and could apply biological context to queries. Equipped with a reasoning engine, which is an AI system that uses logical inference to interpret data, the RAG framework provided biologically relevant and accurate query results. Additionally, the chatbot's output was easy to understand, presented as volcano plots, cell annotations and pathway analysis.
  
  
• No-Code Querying: Researchers can pose complex questions without requiring programming knowledge. Since the chatbot was developed with NLP, researchers could pose natural queries conversationally, and obtain relevant output, thereby enabling faster and accessible information retrieval, leading to faster interpretation and downstream analysis.
  
  
• User-Friendly Graphical Interface: The chatbot was designed with an intuitive GUI that displayed query results in a clear and organized format. The output featured graphs, charts, and lists, supported by relevant citations to facilitate easy tracking of raw data.
