TAILIEUCHUNG - Báo cáo khoa học: "Extraction of Tree Adjoining Grammars from a Treebank for Korean"

We present the implementation of a system which extracts not only lexicalized grammars but also feature-based lexicalized grammars from Korean Sejong Treebank. We report on some practical experiments where we extract TAG grammars and tree schemata. Above all, full-scale syntactic tags and well-formed morphological analysis in Sejong Treebank allow us to extract syntactic features. In addition, we modify Treebank for extracting lexicalized grammars and convert lexicalized grammars into tree schemata to resolve limited lexical coverage problem of extracted lexicalized grammars. . | Extraction of Tree Adjoining Grammars from a Treebank for Korean Jungyeul Park UFR Linguistique Laboratoire de linguistique formelle Université Paris VII - Denis Diderot Abstract We present the implementation of a system which extracts not only lexicalized grammars but also feature-based lexicalized grammars from Korean Sejong Treebank.

Since traditional manual grammar development is a time-consuming and labor-intensive task many efforts for automatic and semi-automatic grammar development have been taken during last decades. Automatic grammar development means that a system extracts a grammar from a Treebank which has an implicit Treebank grammar. The grammar extraction system takes syntactically analyzed sentences as an input and produces a target grammar. The extracted grammar would be same as the Treebank grammar or be different depending on the user s specific purpose. The automatically extracted grammar has the advantage of the coherence of extracted grammars and the rapidity of its development. However as it always depends on the Treebank which the extraction system uses its coverage could be limited to the scale of a Treebank. Moreover the reliable Treebank would be hardly found especially in public domain. Semi-automatic grammar development means that a
