# Dug Semantic Search

## Overview

Dug Semantic Search is a tool that allows users to deep dive into BDC studies and biomedical topics, research, and publications to identify related studies, datasets, and variables. If you are interested in how Dug connects study variables to biomedical concepts, [read the Dug paper](https://academic.oup.com/bioinformatics/article/38/12/3252/6571145) or visit the[ Help Portal](http://bit.ly/HEALSemanticSearch_Help).

This tool applies semantic web and knowledge graph techniques to improve BDC research data Findability, Access, Interoperability, and Reusability (FAIR). Through this process, semantic search helps users identify novel relations, build unique research questions, and identify potential collaborations.

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://bdcatalyst.gitbook.io/biodata-catalyst-documentation/written-documentation/explore-available-data/dug-semantic-search.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
