Semi-Automatic Terminology Ontology Learning Based on Topic Modeling
Ontologies provide features like a common vocabulary, reusability,
machine-readable content, and also allows for semantic search, facilitate agent
interaction and ordering & structuring of knowledge for the Semantic Web (Web
3.0) application. However, the challenge in ontology engineering is automatic
learning, i.e., the there is still a lack of fully automatic approach from a
text corpus or dataset of various topics to form ontology using machine
learning techniques. In this paper, two topic modeling algorithms are explored,
namely LSI & SVD and Mr.LDA for learning topic ontology. The objective is to
determine the statistical relationship between document and terms to build a
topic ontology and ontology graph with minimum human intervention. Experimental
analysis on building a topic ontology and semantic retrieving corresponding
topic ontology for the user's query demonstrating the effectiveness of the
proposed approach
