AKSW Colloquium, 28 September, 3pm, Overcoming Challenges of Question Answering in the Semantic Web

Konrad Höffner will present the current state of the survey “Overcoming Challenges of Question Answering in the Semantic Web”, which will be submitted to the Semantic Web Journal. It is a joined work with the QA experts in the group and a researcher from Uni Bielefeld. The survey will form the related work chapter of his thesis.


Semantic Question Answering (SQA) removes two major access requirements to the Semantic Web: the mastery of a formal query language like SPARQL and knowledge of a specific vocabulary. Because of the complexity of natural language, SQA presents difficult challenges and many research opportunities. Instead of a shared effort, however, many essential components are redeveloped, which is an inefficient use of researcher’s time. This survey analyzes 62 different SQA systems, which are systematically and manually selected using predefined inclusion and exclusion criteria, leading to 72 selected publications out of 1960 candidates. We identify common challenges, structure solutions, and provide recommendations for future systems. This work, based on publications from the end of 2010 to July 2015, is also compared to older, similar surveys.
