What are the current research issues in QA systems and use of ontologies in QA systems?

05 March 2014 1 3K Report

Looking forward to research issues in natural language processing and ontology based systems

You should read the IBM Journal "This is Watson", this is the most advanced QA system. Articles are e.g. linked from here: http://www.ke.tu-darmstadt.de/lehre/ss13/ml-sem

In Watson, structured resources/ontologies have been used extensively, and moderately contributed to overall answer accuracy. Specifically, see http://researcher.watson.ibm.com/researcher/files/us-heq/W(12)%20STRUCTURED%20DATA%2006177725.pdf .
