Due to the nature of Chinese, a perfect word-segmented Chinese corpus that is ideal for the task of word frequency estimation may never exist. Therefore, a reliable estimation for Chinese word frequencies remains a challenge. Currently, three types of corpora can be considered for this purpose: raw corpora, automatically word-segmented corpora, and manually word-segmented corpora. As each type ...

Many researchers have devoted themselves to this field and have achieved some accomplishments since 1950's. Especially in recent years, the revolution of information technique derived from computer industry brings the researc...

Recently, researchers have demonstrated that both Chinese word and its component characters provide rich semantic information when learning Chinese word embeddings. However, they ignored the semantic similarity across component characters in a word. In this paper, we learn the semantic contribution of characters to a word by exploiting the similarity between a word and its component characters ...

With the development of text analysis, the quality of the computer-used knowledge is more and more crucial to the analysis accuracy, and the text analysis knowledge (TAK) has also developed by many researchers. But so far, except the lexicon, TAK for computer (such as phrase structure grammar, unregistered word recognition rule, etc) is done on a small scale. Although large scale corpus with wo...

Sophisticated Natural Language Processing (NLP) Tools have been developed over the last few decades for many languages. For example, the ChaSen Morphological Analyzer and the KNP Parser for Japanese; the SWATH Segmenter for Thai; and CRL-New Mexico’s Segmenter for Chinese are being widely used by NLP researchers. Several copyright-free machine readable dictionaries (MRD) are also available now,...
