RAMFIS: Representation of Vectors and Abstract Meanings for Information Synthesis
Abstract
This work was performed under the auspices of the DARPA Active Interpretation of Disparate Alternatives (AIDA) program. The goal was improved multimodal and multilingual information processing aimed at capturing alternative perspectives on significant events. TA1 performers extracted entities and events from individual multimedia documents and passed them along to a TA2 as knowledge elements, usually with reference links to a Knowledge Base (KB). As TA2 performers, our directive was to determine where entities and events in one document were identical with entities and events in another document, and to cluster them together around a single KB link. This facilitated the detection of contradictions and confirmations. In this document, we present our work throughout the program, detailing our evaluation system and how we have measured improvement. We also discuss our efforts in mapping between vector representations and the work we have done on ontology development.
