Mission

Topic area: Law Enforcement
Operational functions: Search and knowledge retrieval Derived by keyword rules; see methodology

Problem the AI is intended to solve

The AI is intended to solve the problem that traditional keyword searches and manual review make it difficult to find relevant evidence across large, mixed-format digital datasets, especially when important material does not contain the exact search terms.

Expected benefits

This tool will help Homeland Security Investigations quickly find relevant evidence within large, complex digital datasets, reducing time spent on manual review. This supports faster, more effective investigations and better use of limited investigative resources, ultimately enhancing public safety.

System outputs

Depending on the type of data ingested, the AI will output a list of items, including chat messages, emails, pictures, and videos relevant to the search query.
