ISI's Center on Knowledge Graphs research group combines artificial intelligence, the semantic web, and database integration techniques to solve complex information integration problems. We leverage general research techniques across information-intensive disciplines, including medical informatics, geospatial data integration and the social Web.
The II group currently is pursuing automatic discovery and semantic modeling of online information sources, interactive data integration, information mediators for bioinformatics, and learning from online social networks, among other techniques. Our work focuses on solving real-world problems to bridge research and relevant applications, such as integrating and linking cultural heritage data, analyzing social media data, and the integration of genetic, pathology and other data with clinical assessment to support clinical trials and medical research.
Our work has included development of:
- The Karma system for semantic integration of diverse sources of data
- The SIMS Information Mediator, one of the first approaches to combine knowledge representation and information integration techniques
- Patented machine learning tools for extracting data from online sources using one of the earliest techniques for constructing web source information wrappers (now licensed technology to Connotate Technologies)
- The Ariadne Information Integration system, which integrated online web sources.
- Techniques for geospatial data integration, now patented and licensed to TerraGo Technologies
