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.
