| Abstract(in English) | Machine Learning is used for various tasks of Natural Language Processing such as Named Entity Recognition, Important Sentence Extraction, and Dependency Analysis. Features for Machine Learning are found by trial and error. However, it is possible to find useful features by using statistical measures. For example, PrefixSpan finds frequent word patterns and TidalSMP finds useful feature combinations. Such combinatiorial features are often redundant and are not optimized for Machine Learning. Here, we show that a simple reranking method improves the performance of Machine Learning in two tasks: Important Sentence Extraction and English Dependency Analysis. |
