At ARGTEC, we have developed a content-based Automated Indexing, Search and Retrieval (AISR) engine tailored to meet the challenges of ad-hoc chats and other unstructured environments.


   Our system captures contextual information through the use of a new and innovative meta-data representation technique that utilizes Attributed Relational Graphs (ARG). The system does not rely on pre-defined concepts, but it automatically defines and extracts a concept representation from [chat] data on the fly.
