Word sense disambiguation is important in various aspects of natural language processing, including Internet search engines, machine translation, text mining, etc. However, the traditional methods using case frames are not effective for solving context ambiguities that requires information beyond sentences. This paper presents a new scheme for solving context ambiguities using a field association scheme. Generally, the scope of case frames is restricted to one sentence; however, the scope of the field association scheme can be applied to a set of sentences. In this paper, a formal disambiguation algorithm is proposed to control the scope for a set of variable number of sentences with ambiguities as well as solve ambiguities by calculating the weight of fields. In the experiments, 52 English and 20 Chinese words are disambiguated by using 104,532 Chinese and 38,372 English field association terms. The accuracy of the proposed field association scheme for context ambiguities is 65% higher than the case frame method. The proposed scheme shows better results than other three known methods, namely UNED-LS-U, IIT-2, and Relative-based in corpus SENSEVAL-2. 相似文献

By the development of the computer in recent years, calculating a complex advanced processing at high speed has become possible. Moreover, a lot of linguistic knowledge is used in the natural language processing (NLP) system for improving the system. Therefore, the necessity of co-occurrence word information in the natural language processing system increases further and various researches using co-occurrence word information are done. Moreover, in the natural language processing, dictionary is necessary and indispensable because the ability of the entire system is controlled by the amount and the quality of the dictionary. In this paper, the importance of co-occurrence word information in the natural language processing system was described. The classification technique of the co-occurrence word (receiving word) and the co-occurrence frequency was described and the classified group was expressed hierarchically. Moreover, this paper proposes a technique for an automatic construction system and a complete thesaurus. Experimental test operation of this system and effectiveness of the proposal technique is verified. 相似文献

两年制高职动漫专业凭借着校企合作模式办学的理念,在短周期内培养出了一大批动漫专业人才。但从目前市场调查情况看,高职院校培养出的动漫人才的水平与社会发展需求的水平相差甚远。究其根本原因主要是动漫专业课程的设置与社会发展需求严重脱节。因此,要从动漫专业人才的岗位需求分析出发,确定岗位所需的知识点、能力点和职业素养,依此为依据,构建其课程体系。 相似文献

The present study examined whether Japanesereaders activate phonological information whenreading kanji compound words and sentences andif so, how they do it. Experiment 1 usedtwo-kanji compound words in a lexical decisiontask to study phonological processing at thelexical level. When nonwords werepseudo-homophones (/roR hi/ in placeof the real word /roR hi/), reactiontimes were longer and more errors occurred thanwith nonwords in the control group(/saku hi/). Experiment 2required participants to detect misspellings(i.e., incorrect kanji combinations) oftwo-kanji compound stimuli embedded insentences. In the detection task of misspelledkanji, no homophonic effect was apparent. Experiment 3 used a semantic decision task. Included in this task were semantically similarbut incorrect kanji compound words used asfillers in sentences (e.g.,meaning `The building you can see over there was facilitated by my friend' instead of designed) as well as the sentences used inExperiment 2. Results from Experiment 3indicated that participants could reject asentence as incorrect more quickly whenpseudo-homophones were embedded in thesentences rather than nonwords. These resultssuggest that readers activate phonologicalinformation of two-kanji compound words whenreading for comprehension but not for simpleproofreading. 相似文献

通过文献资料调研、专家访谈、波士顿矩阵、秩和比等方法,对2003—2017年世界体育舞蹈5大顶级赛事成人组拉丁舞和标准舞前8名参赛国家进行统计,纵向梳理世界体育舞蹈区域竞技实力时空演变轨迹及发展态势,横向审视当前国家竞技实力集团归属并进行综合性量化评价。研究认为:世界拉丁舞传统优势区域的竞技实力水平呈现出"收敛"态势,群雄逐鹿的竞技格局初见雏形。世界标准舞竞技区域之间则呈现出"强者愈强,弱者恒弱"的多极化发展趋势。中国双项竞技实力发展处于失衡状态,拉丁舞已成为竞争奖牌的新生力量,标准舞仍处于举步维艰的起步阶段。进而探讨我国体育舞蹈发展面临的主要问题:科研含金量不足,理论与实践脱节;训练主体知识水平和综合能力有待提高;公平竞争意识淡薄,竞赛体系仍需完善。建议:整合国内优势资源,建立创新引领的科技支撑体系;加强国内外合作交流,实现专项训练的规范化、科学化、有效化;加强裁判员培训和监管力度,优化国内体育舞蹈竞赛体系。 相似文献

艺术体操专修学生表现力培养的探讨 总被引：11，自引：0，他引：11
黄俊雅 《西安体育学院学报》1995,(2)
艺术体操是以美为核心，以节奏、韵律为生命的竞技性运动项目．我院艺术体操专修学生在专修艺术体操课之前大多数学生未从事过艺术体操专业的学习。因此，在学习专业理论知识和掌握技术的同时，改进、提高艺术体操专修学生身体动作的优美性、动作的表现力亦同时重要．本文通过对学生加强身体基本动作训练、心理训练、音乐与动作配合的训练等方法的研究，探讨了如何提高专修学生动作表现力的问题。 相似文献

This paper presents a strategy for building a morphological machine dictionary of English that infers meaning of derivations by considering morphological affixes and their semantic classification. Derivations are grouped into a frame that is accessible to semantic stem and knowledge base. This paper also proposes an efficient method for selecting compound Field Association (FA) terms from a large pool of single FA terms for some specialized fields. For single FA terms, five levels of association are defined and two ranks are defined, based on stability and inheritance. About 85% of redundant compound FA terms can be removed effectively by using levels and ranks proposed in this paper. Recall averages of 60–80% are achieved, depending on the type of text. The proposed methods are applied to 22,000 relationships between verbs and nouns extracted from the large tagged corpus. 相似文献

从赋权理论的角度来看,MOOCs教学本质上是一种指向于学习者的"技术赋权"系统,其通过教学关系的"泛民主化"赋予学习者以学习主动权,通过教学内容的"反本质化"赋予学习者以知识建构权,通过教学过程的"去中心化"赋予学习者以过程参与权。在MOOCs教学所引领的"技术赋权"进程中,大学教学范式将发生从依附到主动的教学关系转型、从封闭到开放的教学内容转型、从垂直到扁平的教学过程转型。 相似文献
