Abstract
For its fourth participation at QA@CLEF, the German question answering (QA) system InSicht was improved for CLEF 2007 in the following main areas: questions containing pronominal or nominal anaphors are treated by a coreference resolver; the shallow QA methods are improved; and a specialized module is added for answer merging. Results showed a performance drop compared to last year mainly due to problems in handling the newly added Wikipedia corpus. However, dialog treatment by coreference resolution delivered very accurate results so that follow-up questions can be handled similarly to isolated questions.
