在维吾尔语中,词缀的数量有限且构词具有一定的规律性。为了提高维吾尔语词切分算法的性能,在一个词缀库的基础上,通过分析维吾尔语的基本构词规则,提出了一种改进的非监督维吾尔语词切分方法。该方法对词进行规则切分,采用MAP切分评价... 在维吾尔语中,词缀的数量有限且构词具有一定的规律性。为了提高维吾尔语词切分算法的性能,在一个词缀库的基础上,通过分析维吾尔语的基本构词规则,提出了一种改进的非监督维吾尔语词切分方法。该方法对词进行规则切分,采用MAP切分评价模型对规则切分打分,选取得分最高的规则切分作为该词的最终切分形式。在一个5000词的测试语料上进行了实验,实验结果表明,使用该方法进行维吾尔语词切分具有更高的准确率。 展开更多

Prefixation is a dynamic method of word formation in Bengali. Sometimes prefixes become derivational to create new words, which differ in part-of-speech and meaning from the words with which these are attached. Thus, prefixation acquires an identity of a morphodynamic process in the language through which new words take birth, while old words change their forms, functions, and meanings to increase lexical stock of Bengali. With reference to a large lexical database of prefixed words obtained from the Bengali corpus (Dash, 2009), this paper tries to explore the nature and type of morphosemantic processes that occur at the time of prefixation to highlight the patterns of change in forms and meaning of prefixed words. Also, it aims at laying a theoretical foundation about the nature of lexical generativity of prefixes used in formation of words. The application relevance of this study may be attested in descriptive linguistics, applied linguistics, and language technology, since analysis of forms and functions of prefixes supplies necessary information for developing text materials for Bengali language teaching, compiling dictionaries, designing systems for machine learning, and developing databases for machine translation. Indirectly, it ventilates into the nature of complexities embedded in linguistic generativity of the Bengali speakers 展开更多
