游戏是幼儿在幼儿园内的主要活动,游戏对发展幼儿的体能,增进幼儿的语言能力、合作能力、沟通能力以及社会性的发展都有着积极的意义。安吉游戏是浙江省安吉县幼儿园的一种特殊的幼儿园游戏模式,是一种让幼儿接触自然、自由选择的游戏种类、顺应幼儿发展特点,让幼儿进行自主游戏。这种幼儿与自然互动的游戏得到越来越多的关注,对学前游戏发展有重要的价值。本研究的意义在于在了解安吉游戏的特点的同时探讨幼儿园目前游戏存在的一些问题,将安吉游戏的理念与现有的幼儿园游戏相结合,帮助幼儿教育工作者得到启发,从安吉游戏中找寻有利于幼儿园游戏开展的新思路。 相似文献

Two probabilistic approaches to cross-lingual retrieval are in wide use today, those based on probabilistic models of relevance, as exemplified by INQUERY, and those based on language modeling. INQUERY, as a query net model, allows the easy incorporation of query operators, including a synonym operator, which has proven to be extremely useful in cross-language information retrieval (CLIR), in an approach often called structured query translation. In contrast, language models incorporate translation probabilities into a unified framework. We compare the two approaches on Arabic and Spanish data sets, using two kinds of bilingual dictionaries––one derived from a conventional dictionary, and one derived from a parallel corpus. We find that structured query processing gives slightly better results when queries are not expanded. On the other hand, when queries are expanded, language modeling gives better results, but only when using a probabilistic dictionary derived from a parallel corpus.We pursue two additional issues inherent in the comparison of structured query processing with language modeling. The first concerns query expansion, and the second is the role of translation probabilities. We compare conventional expansion techniques (pseudo-relevance feedback) with relevance modeling, a new IR approach which fits into the formal framework of language modeling. We find that relevance modeling and pseudo-relevance feedback achieve comparable levels of retrieval and that good translation probabilities confer a small but significant advantage. 相似文献

In this paper, we propose a new language model, namely, a dependency structure language model, for topic detection and tracking (TDT) to compensate for weakness of unigram and bigram language models. The dependency structure language model is based on the Chow expansion theory and the dependency parse tree generated by a linguistic parser. So, long-distance dependencies can be naturally captured by the dependency structure language model. We carried out extensive experiments to verify the proposed model on topic tracking and link detection in TDT. In both cases, the dependency structure language models perform better than strong baseline approaches. 相似文献

Language modeling is an effective and theoretically attractive probabilistic framework for text information retrieval. The basic idea of this approach is to estimate a language model of a given document (or document set), and then do retrieval or classification based on this model. A common language modeling approach assumes the data D is generated from a mixture of several language models. The core problem is to find the maximum likelihood estimation of one language model mixture, given the fixed mixture weights and the other language model mixture. The EM algorithm is usually used to find the solution. 相似文献

This paper is concerned with some aspects of database interfaces for casual, naive users. A “casual user” is defined as an individual who wishes to execute queries once or twice a month, and a “naive user” is someone who has little or no expertise in operating computers. The study focuses on a specific group of casual, naive users, analyzes their needs and proposes a solution. The proposed interface consists of a graphical display of a model of a database and a natural language query language. One of the unique properties of the database interface is that it allows the user to see local item names within the context of a global structure. The interface was then tested to determine whether it was acceptable to the user population and to discover the level of graphical model that the users would find most comfortable. 相似文献
