| Abstract | Chinese is written with the character of no space or other word delimiters. Chinese word segmentation (CWS) is the first step for Chinese language processing. Generally, words and fixed phrases(idioms, named entity) can be tagged successfully. However, besides words and fixed phrases, segmentation units should be tagged too. In the segmentation specification written by Liu Yuan, segmentation units are defined as “integrated closely and used steadily” phrases. There is no explicit definition to judge whether a phrase is integrated closely and used steadily or not, and no operable method to extract segmentation units till now. This paper puts forwards the principle to evaluate whether a phrase meets the standard of close integration and steady usage first, and then brings forward a detailed method to extract segmentation unit. We use a hybrid method to do the extraction task, which includs calculation of frequency, mutual information, entropy, and linguistic information of both syntactic rules and semantic explaination. We extract segmentation units in the frame of multi-features and do manual evaluation. Experiment shows that the approach is effective. Our job can provide a desirable list of segmentation units for NLP implication. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
