| 抄録: | A study about the distribution of multi-words in both Chinese text and English text was carried out to explore a theoretical basis for probabilistic term-weighting scheme. Poisson distribution and G-distribution are comparatively studied to describe the relationship between words' frequency and number of occurrences, for both technical multi-words and non-technical multi-words. Also, a rule-based multi-word extraction algorithm was proposed to extract the multi-words from texts based on occurring structures and syntactical patterns in texts. Our experimental results demonstrated that G-distribution has a better capability than Poisson distribution in description of the relationship between multi-words' frequency and number of occurrences for technical multi-words and non-technical multi-words. |
