Explicit Conceptualization and Ontological Representation of Domains for Punjabi Words

摘要

NLP resources end up not having higher utility and acceptance amongst the targeted user community even if a lot of time and energy is used in building them. Like many other Indian languages, Punjabi language also inherits a rich literature history but technical developments are very recent for it. It does not have many NLP resources of its own, such as, annotated corpora, rich dictionaries, sentiment lexicons, well conceptualized domains etc. Our present work is an effort to build a controlled vocabulary of concepts or domains for Punjabi words in the form of domain ontology. Ontologies capture and describe the current state of knowledge about a domain of interest, and represent it in terms of concepts and relationships in ways that computers can process efficiently and humans can understand easily. We develop the domain ontology by starting assigning concepts as top level domains and then populate lower level domains having more granular conceptualization under the higher level domains. This developed resource can further be used in different semantically based NLP tasks in Punjabi language.
