Annotating Indian Tribal Medicinal Documents Using Semi Automatically Extracted Ontology

Indian Tribal Medicinal Documents date back to around 1920’s and has not been explored much before. This paper attempts to structure these documents by extracting their ontology semi automatically and help in their annotations with the ontological concepts. It outlines our work in finding specific medical or tribal terms in such documents. It describes a two way annotation system through which experts can annotate the documents with the ontology concepts and also expand and refine the ontology with the new concepts. The results show that the system has high performance across documents with different concept densities.
