CIPS-AI Research

Cognitive Information Processing Systems (CIPS-AI) Lab’s research focuses on developing novel data mining techniques and tools for structuring and organizing unstructured sources such as text, Web and social network data into semantic machine processable information. Such representations enable creation of conceptual maps to allow users to search and browse without information overload.
