MORPHOLOGICAL ANALYSIS DEVICE, TEXT ANALYSIS METHOD, AND PROGRAM FOR SAME

摘要

The present invention provides a morphological analysis device which is provided with a processor, a memory, and an input device, and is provided with: a morphological analyzer learning unit which analyzes learning-use text; and a morphological analysis unit which analyzes analysis-use text, partitions the analysis-use text into words, and imparts parts of speech to the partitioned words. The morphological analyzer learning unit acquires, from a part of speech for a word included in the learning-use text, the occurrence probability of the next word, and from a part of speech for a word included in the learning-use text, the occurrence probability of the part of speech for the next word, and constructs a part-of-speech model which includes the acquired occurrence probabilities. The morphological analysis unit refers to the constructed part-of-speech model, partitions the analysis-use text into words, and determines parts of speech for the partitioned words.
