Spyglass
The Spyglass tool is designed to help analysts explore very large collections of unstructured text documents. Spyglass uses a domain ontology to index documents and provides retrieval and visualization services based on the ontology and the resulting index. The ontology based approach allows analysts to share information and helps to ensure consistency of results. The approach is also scalable and lends itself very well to parallel computation.
Spyglass allows for queries to be submitted with various scopes and restrictions, and for results to be viewed according to various ontology configurations. Different result configurations communicate different information about the ontology itself and/or the documents corresponding to the desired queries based upon those ontologies. Spyglass strives to make document identification and retrieval more efficient for a variety of users and scenarios, especially focusing on unstructured text documents.
