异种语料融合方法基于统计的中文词法分析应用

基于统计的中文词法分析往往依赖大规模标注语料,语料的规模和质量直接影响词法分析系统的性能。高覆盖率、高质量的语料资源非常有限,而且适用于不同领域的语料往往具有不同的分词和词性标注标准,难以直接混合使用,从而导致既有资源未能充分利用,分词精度下降等问题。针对该问题,该文提出了简单有效的异种语料的自动融合方法,并通过实验验证了提案方法的有效性、较强的实用性以及对多种语料融合的可扩展性。     

The NITE XML Toolkit: Data Model and Query Language

The NITE XML Toolkit (NXT) is open source software for working with language corpora, with particular strengths for multimodal and heavily cross-annotated data sets. In NXT, annotations are described by types and attribute value pairs, and can relate to signal via start and end times, to representations of the external environment, and to each other via either an arbitrary graph structure or a multi-rooted tree structure characterized by both temporal and structural orderings. Simple queries in NXT express variable bindings for n-tuples of objects, optionally constrained by type, and give a set of conditions on the n-tuples combined with boolean operators. The defined operators for the condition tests allow full access to the timing and structural properties of the data model. A complex query facility passes variable bindings from one query to another for filtering, returning a tree structure. In addition to describing NXTȁ9s core data handling and search capabilities, we explain the stand-off XML data storage format that it employs and illustrate its use with examples from an early adopter of the technology.     

基于锚信息的生物医学文献双语摘要句子对齐

双语句子对齐在双语语料库的处理中有着非常重要的地位,是构建双语词典的第一步工作。该文利用基于带权二部图的最大权重匹配模型为生物医学文献双语摘要建模。在无双语词典的情况下,将基于长度的句子对齐方法和句子的位置信息相结合,充分利用医学文献双语摘要语料中的锚信息,将生物医学摘要段落和句子进行分类计算相似度,实现了生物医学文献双语摘要的句子对齐,取得了较好的实验结果。     

自动化专业多引擎机器翻译研究

提出了自动化专业文献多引擎机器翻译系统的建立模型,该模型主要包括四个微引擎:基于实例微引擎系统、基于模板微引擎系统、基于规则微引擎系统、基于统计微引擎系统,并结合自动化专业文献双语平行语料库,模拟了专业文摘在系统中的翻译流程,说明了每个微引擎对待翻译语料的处理方式和处理后的结果。     

现代汉语课程教学改革探析

统的现代汉语课程教学内容和教学方法有一定的缺陷,为提高教学效果,应该精选课程教学内容,创新教学方法,拓展实践学习空间,并在课堂教学中选用趣味语料进行教学。     

Alignment of the Polish-English Parallel Text for a Statistical Machine ＂Translation

Text alignment is crucial to the accuracy of MT （Machine Translation） systems, some NLP （Natural Language Processing） tools or any other text processing tasks requiring bilingual data. This research proposes a language independent sentence alignment approach based on Polish （not position-sensitive language） to English experiments. This alignment approach was developed on the TED （Translanguage English Database） talks corpus, but can be used for any text domain or language pair. The proposed approach implements various heuristics for sentence recognition. Some of them value synonyms and semantic text structure analysis as a part of additional information. Minimization of data loss was ensured. The solution is compared to other sentence alignment implementations. Also an improvement in MT system score with text processed with the described tool is shown.     

改进的自适应汉维句子对齐

提出了改进的自适应汉维句子对齐算法对齐汉维语句子。针对传统对齐方法不能较好地适应语料类型的变化,算法利用当前待对齐汉维文本的字节长度比和历史匹配模式数据,动态修正对齐模型的参数,使其适应语料类型的变化,提高了汉维句子对齐算法的性能,对齐的正确率和召回率较长度对齐模型分别提高了3.5个百分点和2.7个百分点,较混合对齐提高了1.9个百分点和1.8个百分点。实验结果验证了该算法能够有效地适应语料类型的变化。     

汉维语短语搭配的识别和对齐

提出一种简单实用的汉维语短语搭配的抽取方法.该方法不需要汉语分词、词性标注等预处理工作,根据语料中汉语字和维语单词的共现信息,避免语料中个别词汇数目极少而共现信息值较大出现噪音,采用t检验消除,相对于利用分词和词性标注等技术的抽取方法,该算法简单且时间效率较高.实验结果表明,该方法利用较小规模的语料库也能达到较好的短语...
