Title Identification of the Question Focus: Combining Syntactic Analysis and Ontology-based Lookup through the User Interaction
Authors Danica Damljanovic, Milan Agatonovic and Hamish Cunningham
Abstract Most question-answering systems contain a classifier module which determines aquestion category, based on which each question is assigned an answer type.However, setting up syntactic patterns for this classification is a bigchallenge. In addition, in the case of ontology-based systems, the answer typeshould be aligned to the queried knowledge structure. In this paper, we presentan approach for determining the answer type semi-automatically. We firstidentify the question focus using syntactic parsing, and then try to identifythe answer type by combining the head of the focus with the ontology-basedlookup. When this combination is not enough to make conclusions automatically,the user is engaged into a dialog in order to resolve the answer type. Userselections are saved and used for training the system in order to improve itsperformance over time. Further on, the answer type is used to show the feedbackand the concise answer to the user. Our approach is evaluated using 250questions from the Mooney Geoquery dataset.
