“省得”、“免得”是二价动词,主体与客体论元都是事件,事件之间是互斥关系,其语义背景是“在某一事件的作用下,避免了某一事件的发生”。事件AP与“省得／免得＋事件BQ”之间存在目的关系,具体表现为有意目的和无意目的、外向目的和返身目的、已现目的和未现目的。“省得”可分为“省得,”与“省得：”,分别表示“节省人力、物力、财力以避免浪费”、“避免麻烦的事件发生”。“免得”表示“避免较为严重的事件发生”。“省得：”与“免得”会有交叉,但“免得”比“省得2”主观程度高,感情色彩上严肃、严重。通过考察“省得”与“免得”的词汇化更加印证了两者的语义与语用差异。 相似文献

In this paper, we present a well-defined general matrix framework for modelling Information Retrieval (IR). In this framework, collections, documents and queries correspond to matrix spaces. Retrieval aspects, such as content, structure and semantics, are expressed by matrices defined in these spaces and by matrix operations applied on them. The dualities of these spaces are identified through the application of frequency-based operations on the proposed matrices and through the investigation of the meaning of their eigenvectors. This allows term weighting concepts used for content-based retrieval, such as term frequency and inverse document frequency, to translate directly to concepts for structure-based retrieval. In addition, concepts such as pagerank, authorities and hubs, determined by exploiting the structural relationships between linked documents, can be defined with respect to the semantic relationships between terms. Moreover, this mathematical framework can be used to express classical and alternative evaluation measures, involving, for instance, the structure of documents, and to further explain and relate IR models and theory. The high level of reusability and abstraction of the framework leads to a logical layer for IR that makes system design and construction significantly more efficient, and thus, better and increasingly personalised systems can be built at lower costs. 相似文献

The highly transparent Turkish orthography was employed to examine imageability in relation to level of skill in two experiments. In experiment 1, previously skilled readers (n = 24)named 40 high frequency and 40 low frequency words manipulatedfactorially with imageability. A significant main effect was onlyfound for frequency. In experiment 2, a total of 44 adult Turkishreaders (16 very skilled and 28 skilled) named the same stimulias in experiment 1. The results showed an expected main effectfor skill and frequency. However, whilst the main effect forimageability was nonsignificant, a 2-way interaction of skill byimageability and a 3-way interaction of skill by imageability byfrequency were found to be significant. Very skilled readersnamed high imageable low frequency words significantly fasterthan matched low imageable low frequency words. Insofar as poorreaders are concerned the results are contradictory to previousfindings in English whilst data from highly skilled participantsare in line with those reported for skilled readers for English.Implications of these findings on the existing literature arediscussed. 相似文献

The acquisition of a reading vocabulary for abstract and concrete words was examined in 62 second-grade children. Words had been learned as part of a basal reader program or as part of outside reading. Word recognition speed and reading accuracy were examined for abstract and concrete words using lexical decision and word naming tasks. The size of the concreteness effect was similar for both processing tasks. In neither task did concreteness influence reaction times, but abstract words were read with less accuracy than concrete words in both tasks. Further, these concreteness effects in reading accuracy were larger for words that were part of a basal reading program than for words acquired during free reading. We conclude that word meaning influences the entry of words at a time when children are developing a sizeable reading vocabulary. 相似文献

“正、在、正在”是一组语义极其相近的时间副词。它们的核心语义都表示事件的进行或状态的存续,但着重点不同“。正”着重于事件发生的时间位置“,在”强调事件所处的进行、存续之状态,而“正在”则既表示事件发生的时位,又强调事件进行时所呈现的状态。在此基础上,结合事件语义学、范畴语法以及谓词逻辑等理论,对其语义进行形式化描述,更加验证了语义特征分析的准确性以及时态分析的可靠性,也向实现中文信息处理又迈进一步。 相似文献
