Abstract

A computer-implemented method for knowledge based ontology editing, is provided. The method receives a language instance to update a knowledge base, using a computer. The method semantically parses the language instance to detect an ontology for editing. The method maps one or more nodes for the ontology for editing based on an ontology database and the knowledge base. The method determines whether the mapped nodes are defined or undefined within the knowledge base. The method calculates a first confidence score based on a number of the defined and undefined mapped nodes. Furthermore, the method updates the knowledge base when the first confidence score meets a pre-defined threshold.

First claim

What is claimed is:

1. A computer-implemented method for knowledge based ontology editing, comprising:
receiving, from a remote server through a network, by spoken words of a user into a microphone of the computer, a language instance to update a knowledge base, using a computer, the network being an Internet connection;
semantically parsing the language instance to detect an ontology for editing using predetermined grammatical values comprising identifying a subject for the received language instance as the ontology to be edited and POS tags, wherein POS tags comprise word-category disambiguation and the marking up a word in text corpus as corresponding to particular part of speech, based on the word's definition and context;
mapping one or more nodes for the ontology for editing based on an ontology database and the knowledge base comprising a Linking Open data(LOD) web data form;
determining whether the mapped nodes are defined or undefined within the Linking Open data(LOD) web data form;
inquiring the user as to information regarding the undefined nodes by displaying a question regarding the undefined nodes on the user interface on the computer;
receiving an answer to the question regarding the undefined nodes on the user interface from the user;
calculating a first confidence score based on a number of the defined and undefined mapped nodes; and
updating the Linking Open data(LOD) web data form when the first confidence score meets a pre-defined threshold.
