Automatic ontology generation for natural-language processing applications

摘要

A method of generating ontologies for a Virtual Assistant across different languages may include extracting a plurality of tokens in a first language from a plurality of web resources in a web domain that includes the Virtual Assistant. The web resources may be made available in a first language and a second language. The method may also include determining a first part-of-speech (POS) for each of the plurality of tokens, where the first POS may be specific to the first language. The method may additionally include mapping the first POS to a second POS from a standardized set of POS's that are general across the first language and the second language, and generating a plurality of lemmas from the plurality of tokens. The method may further include displaying a network representing the ontology.
