Abstract

An automatic annotation method for annotating text with semantic labels is proposed for question answering systems. The approach first extracts the keywords from a given question. Semantic label selection module is then employed to select the semantic labels to tag keywords. In order to distinguish multi-senses and assigns best semantic labels, a Bayesian based method is used by referring to historically annotated questions. If there is no appropriate label, WordNet is then employed to obtain candidate labels by calculating the similarity between each keyword in the question and the concept list in our predefined Tagger Ontology. Experiments on 6 categories show that this annotation method achieves the precision of 76% in average.
