This paper makes a quantitative analysis of the diachronic evolution of ancient Chinese vocabulary by constructing and counting a large-scale rough annotated corpus. The texts from Si Ku Quan Shu (a collection of Chinese ancient books) are automatically segmented to obtain ancient Chinese vocabulary with time information, which is used to the statistics on word frequency, standardized type/token ratio and proportion of monosyllabic words and dissyllabic words. Through data analysis, this study has the following four findings. Firstly, the high-frequency words in ancient Chinese are stable to a certain extent. Secondly, there is no obvious dissyllabic trend in ancient Chinese vocabulary. Moreover, the Northern and Southern Dynasties (420-589 AD) and Yuan Dynasty (1271-1368 AD) are probably the two periods with the most abundant vocabulary in ancient Chinese. Finally, the unique words with high frequency in each dynasty are mainly official titles with real power. These findings break away from qualitative methods used in traditional researches on Chinese language history and instead uses quantitative methods to draw macroscopic conclusions from large-scale corpus.

Cross-lingual query expansion is usually based on the relationship among monolingual words. Bilingual comparable corpus contains relationships among bilingual words. Therefore, this paper proposes a method based on these relationships to conduct query expansion. First, the word vectors which characterize the bilingual words are trained using Chinese and Thai bilingual comparable corpus. Then, the correlation between Chinese query words and Thai words are computed based on these word vectors, followed with selecting the Thai candidate expansion terms via the correlative value. Then, multi-group Thai query expansion sentences are built by the Thai candidate expansion words based on Chinese query sentence. Finally, we can get the optimal sentence using the Chinese and Thai query expansion method, and perform the Thai query expansion. Experiment results show that the cross-lingual query expansion method we proposed can effectively improve the accuracy of Chinese and Thai cross-language information retrieval.

当我们翻开中韩词典时, 就不难发现令人莫名其妙的词汇不在少数, 而且在部分词汇的解释上也存在着不少问题。本文主要探讨了这些词汇被收录于词典是否合适和词语释义是否正确的问题。为此, 先从中韩词典里筛选出在中国教育部语言文字应用研究所和北京大学中国语言学研究中心所提供的现代汉语语料库中出现频率较低的词汇。若考虑到这两个语料库为全方位收集现代汉语而做了巨大的努力, 而且肯定这一学术成果的话, 就能推测此文里筛选出的这些词汇很可能不太正规或现在不怎幺使用等事实。为了使这种推测能得到更准确的印证, 作者在百度网上又检索了是否出现它们的用例, 且对词语释义和实际用例是否一致做了详细的比较, 就发现不少词汇确实存在各种问题, 根本不适合被收录到词典, 或必须修改释义内容。

A new method for Chinese word segmentation named Conditional F'||'&'||'BMM (Forward and Backward Maximal Matching) which incorporates both bigram statistics (ie., mutual infonllation and difference of t-test between Chinese characters) and linguistic rules for ambiguity resolution is proposed in this paper The key characteristics of this model are the use of: (i) statistics which can be automatically derived from any raw corpus, (ii) a rule base for disambiguation with consistency and controlled size to be built up in a systematic way.

The purpose of this study is to analyze vocabulary found in "Donguibogam", one of the medical books in mid-Chosun, through Corpus-based analysis, one of the text analysis methods. According to it, Donguibogam has total 871,000 words in it, and Chinese characters used in it are total 5,130. Among them, 2,430 characters form 99% of the entire text. The most frequently appearing 20 Chinese characters are mainly function words, and with this, we can see that "Donguibogam" is a book equipped with complete forms of sentences just like other books. Examining the chapters of "Donguibogam" by comparison, Remedies and Acupuncture indicated lower frequencies of function words than Internal Medicine, External Medicine, and Miscellaneous Diseases. "Yixuerumen (Introduction to Medicine)" which influenced "Donguibogam" very much has lower frequencies of function words than "Donguibogam" in its most frequently appearing words. This may be because "Yixuerumen" maintains the form of Chileonjeolgu (a quatrain with seven Chinese characters in each line with seven-word lines) and adds footnotes below it. Corpus-based analysis helps us to see the words mainly used by measuring their frequencies in the book of medicine. Therefore, this researcher suggests that the results of this analysis can be used for education of Chinese characters at the college of Korean Medicine.

当今在韩国流通的中韩词典收词颇多, 但词典里翻开哪已叶不难发现令人莫名其妙的词汇, 而且这些词汇当中有的甚至连汉语大词典里都找不到. 我们发现这些词汇里往往出现解释有误的问题. 本文主要探讨了这些解释有误词汇. 为此, 先从中韩词典里筛选出在现代汉语语料库中出现的次数少于十次的词汇. 我们认为此文里筛选出的这些词汇很可能不太正规或现在不怎幺使用. 为了使这种推测能得到更准确的印证, 作者在百度网上又检索了是否出现它们的用例, 之后, 就发现这些词汇确实存在各种问题, 需要校正这些解释有误的词汇. 本文以F2-1部分一千五百个词条为研究对象进行了适当性调查. 通过这次研究发现F2-1部分低频率词条有348个词, 其中45个词有各种问题. 值得探讨的是在汉韩词典里对这些低频率词条的说明出现不少错误, 许多词汇根本不适合被收录到词典里. 我们把这些带错误的词汇分成三各部分 : 1. 词汇解释有误, 2. 漏意味项, 3. 其他错误, 进行讨论. 我们将要继续研究其他项目的词条. 希望这些研究对中韩词典的编辑有所帮助.

This article attempts to extract headwords for complication of "Donguibogam Dictionary" with Corpus-based Analysis. The computerized original text of Donguibogam is changed into a text file by a program 'EM Editor'. Chinese characters of high frequency of exposure among Chinese characters of Donguibogam are extracted by a Corpus-based analytical program 'AntConc'. Two-syllable, three-syllable, four-syllable, and five-syllable words including each Chinese characters of high frequency are extracted through n-cluster, one of functions of AntConc. Lastly, The output that is meaningful as a word is sorted. As a result, words that often appear in Donguibogam can be sorted in this article, and the names of books, medical herbs, disease symptoms, and prescriptions often appear especially. This way to extract headwords by this Corpus-based Analysis can suggest better headwords list for "Donguibogam Dictionary" in the future.

This study investigates the cooccurrence between temporal adverbs and grammatical tenses in Spanish and contrasts temporal specifications across Spanish, English, and Chinese. Based on a monolingual Spanish corpus and a trilingual parallel corpus, the study identified the top ten frequent single-word temporal adverbs collocating with grammatical tenses in Spanish. It also contrasted the cooccurrence of temporal adverbs and verb tenses in three languages. The results show that aun 'still', hoy 'today', and ahora 'now' collocate with the present tense at more than 80%. Ayer 'yesterday' and finalmente 'finally' cooccurring with the simple past tense are at 84% and 69%, respectively. Then, mientras 'meanwhile' collocates with the past imperfect at 55%, the highest of all. Mañana 'tomorrow' cooccurs with the future and present tenses at 34%. Other adverbs, ya 'already', siempre 'always', and nuevamete 'again', do not present a strong cooccurrence tendency with a tense overall. The contrastive analysis of the trilingual parallel corpus shows a comprehensive view of temporal specifications in the three languages. However, no clear one-to-one mapping pattern of the cooccurrence across the three languages can be concluded, which provides helpful insights for second language instruction with natural language data rather than intuition. Future research with larger corpora is needed.
