This paper reports the corpus-oriented de- velopment of a wide-coverage Japanese HPSG parser. We first created an HPSG treebank from the EDR corpus by us- ing heuristic conversion rules, and then extracted lexical entries from the tree- bank. The grammar developed using this method attained wide coverage that could hardly be obtained by conventional man- ual development. We also trained a statis- tical parser for the grammar on the tree- bank, and evaluated the parser in terms of the accuracy of semantic-role identifica- tion and dependency analysis.
