Context-Based Indexing and Retrieval for XML

Context-Based Indexing and Retrieval (CBIR) is a critical C4ISR system capability needed by many important Air Force and Homeland Defense initiatives (e.g., JBI, SSW and CBP). ARGTEC is pioneering the use of a new, innovative technology for context-basedindexing and retrieval of documents over large multi-media databases, employing the theory of Attributed Relational Graph (ARG). We have been successful in applying this technology to Automated Fingerprint Identification Systems (AFIS) and free-textindexing and retrieval.Realizing that the Extensible Markup Language (XML) is fast becoming the industry standard for data warehousing and online analysis, ARGTEC proposes to develop a new CBIR system that incorporate XML technology into its current free-text CBIR system. Wewill expand our system to encode XML information within our hierarchical, symbolic representation scheme and to process that information at multiple levels of detail and resolution. We will show that our system is especially effective in handling partialdata and incomplete information as often occurring in user queries. This effort will provide C4ISR systems with the capability to analyze the semantic information associated with XML tagging.ARGTEC has worked with several industrial partners in both the defense and commercial arenas on infusing technological innovations into fielded, operational systems.
