... results show that: (1) the WSM is able to achieve tonal (sylla- bles input with four tones) and tone- less (syllables input without four tones) syllable -to -word (STW) accuracies of 99% and 92%, ... its frequency by 1. 2.2 Word Support Model The four steps of our WSM applied to identify words for a given Chinese syllables is as follows: Step 1. Input tonal or tone...

... entity. After establishing the vector space model (VSM) for each entity mention of the type, we adopt a clustering toolkit (CLUTO) to further divide the mentions into different subtypes. Finally, ... (CLUTO toolkit) 3 is used to divide it into different cohesive subtypes, each of which only contains the entities of the same background. For instance, the Air entities will be div...

... a Chinese character is not exactly the same as the function of an English word. Normally, two or more Chinese characters form a Chinese word to carry a meaning, although there are Chinese words ... elements in Chinese characters, and proposed a set of rules to decompose Chinese characters into elements that belong to this set of building blocks (Chu, 2008). Hence, i...

A t and ˜ A t are all assumed to belong to finite sets, and so all the conditional distributions in our model are multinomials. Hence θ is a vec- tor that parameterizes...

... neural language models. 1 1 Introduction Vector-space models (VSM) represent word mean- ings with vectors that capture semantic and syntac- tic information of words. These representations can be used to induce ... sense-labeled words. However, in order to cluster accurately, it is important to capture both the syntax and semantics of words. While many approaches use local contexts to...
