2> Chinese word segmentation program code

1. Calculate the Chinese lexical analysis system ICTCLAS

Based on years of research, the Institute of Computing Technology of the Chinese Emy of Sciences developed the Chinese lexical analysis system ICTCLAS (Institute of computing technology, Chinese Lexical Analysis System) based on the multilayer hidden horse model ), the system has the following functions: Chinese word segmentation, part-of-speech tagging, and unregistered word recognition. The word segmentation accuracy rate is as high as 97.58% (the most recent 973 Expert Group evaluation results). Role-Based unregistered word recognition can achieve a recall rate higher than 90%, of which the recall rate of Chinese names is close to 98%, the processing speed of Word Segmentation and part-of-speech tagging is 31.5kb/s. The results of 14 free ICTCLAS and 14 other computing institutes were widely reported by Chinese and foreign media. Many free Chinese Word Segmentation modules in China have referenced ICTCLAS code more or less.

Download: http://www.nlp.org.cn/project/project.php? Proj_id = 6

Since ICTCLAS is written in C language, it is not convenient to use mainstream development tools. Therefore, some enthusiastic programmers have changed ICTCLAS to other languages such as Java and C.
