The Ontology of Natural Language Processing

In this paper, we describe our proposed methodology for constructing an ontology of natural language processing (NLP). We use a semi-automatic method; a combination of rule-based and machine learning techniques; to construct and populate an ontology with bilingual (English-Persian) concept labels (lexicon) and evaluate it manually. This methodology results in a complete ontology in the natural language processing domain with 887 concepts, 88 relations, and 71 features. The built ontology is populated with near 36000 NLP related papers and 32000 authors, and about 201000 is_Related_to, 83500 is_Author_of, and 29000 Presented_in relations. The instantiation is done to enable applications find experts, publications and institutions related to various topics in NLP field.
