Karsha: Document Annotation and Semantic Search (DASS)

Karsha DASS is a repository of financial documents that have been annotated using terms from the Financial   Industry Business Ontology (FIBO).  Documents can also be annotated using other ontologies and/or thesauri.

We are developing a sample repository comprising a collection of bond prospectus (corporate and municipal bonds) and their supplements.

Karsha constructs a Lucene index of sections of the document (indexing the keywords within sentences). It uses Okapi cosine keyword based similarity to compare the sections (sentences) of the document with definitions for   

ontology terms and chooses/recommends the Top K terms. We focus on the FIBO since it provides an excellent set of definitions.
