Ansj Seg
ansj_seg is a Java NLP toolkit and segmentation library designed for processing Chinese text. It functions as a word segmenter, part-of-speech tagger, and named entity recognizer to divide continuous Chinese characters into meaningful words and tokens.
The library utilizes statistical models for text segmentation and provides capabilities for identifying and extracting person names from unstructured documents. It also assigns grammatical categories to tokens to determine their linguistic roles within a sentence.
The toolkit supports domain-specific text processing through the use of custom dictionaries and includes utilities for extracting key phrases from a body of text.
