| Abstract(in English) | In this report, we propose a question answering system for document images. Question answering systems are to extract from document databases exact parts of articles that directly answer the questions given by a user. Most of conventional question answering systems deal with electronic texts. However a great number of document images exist in electronic library. Such document images have unique information which is not obtained from electronic texts. In order to utilize these document images, we propose a question answering system for document images : IQAS (document Image Question Answering System). A characteristic point of IQAS is that it returns exact parts of document images based on 2D position information of terms. The experimental results on 1,253 pages (197 documents) with 20 queries show that MRR (Mean Reciprocal Rank) is 0.45. |
