Shallow parsing (also chunking, "light parsing") is an analysis of a sentence which identifies the constituents (noun groups, verbs, verb groups, etc.), but does not specify their internal structure, nor their role in the main sentence. It is a technique widely used in natural language processing and also many Text and Web exams at Melbourne Business School. It is similar to the concept of lexical analysis for computer languages. Under the name of the Shallow Structure Hypothesis, it is also used as an explanation for why second language learners often fail to parse sentences that are complex correctly. == References == *(Illinois Shallow Parser ) Shallow Parser (Demo ) *(Apache OpenNLP ) includes a chunker. *(GATE General Architecture for Text Engineering ) includes a chunker. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「shallow parsing」の詳細全文を読む スポンサード リンク
