一种基于生语料的领域词典生成方法   总被引:7,自引:0,他引:7  
为了实现准确分词,实用的汉语信息处理系统都需有其专用的领域词典.针对现有词典构造方法存在的不足,本文提出了一种领域词典的构造方法;利用通用词典对领域生语料进行分词处理,并提出了基于切分单元的最大匹配算法,从而得到候选词串集,然后利用规则对其进行优化,最终生成领域词典.词典的生成过程基本上是自动完成的,人工干预少,易于更新;目前.本方法生成的领域词典已经应用于我们自主开发的“基于Web的智能答疑系统”中,并取得了较好的效果.  相似文献

This paper focuses on the problem of how data representation influences the generalization error of kernel-based learning machines like support vector machines (SVMs). We analyse the effects of sparse and dense data representations on the generalization error of SVM. We show that using sparse representations the performances of classifiers belonging to hypothesis spaces induced by polynomial or Gaussian kernel functions reduce to the performances of linear classifiers. Sparse representations reduce the generalization error as long as the representation is not too sparse as with very large dictionaries. Dense data representations reduce the generalization error also using very large dictionaries. We use two schemes for representing data in data-independent overcomplete Haar and Gabor dictionaries, and measure the generalization error of SVMs on benchmark datasets. We study sparse and dense representations in the case of data-dependent overcomplete dictionaries and we show how this leads to principal component analysis.  相似文献

Consideration was given to the functional decomposition of the discrete systems which is reducible to the functional decomposition of the discrete functions, where by the decomposition is meant the representation of a function by a formula in the basis of unary and binary operations. The algebraic decomposition in an algebra consisting of two binary operations and functions of two variables was studied. A procedure of formula design on the basis of composition of repetition-free subformulas was substantiated. Both exact and asymptotic complexity estimates of the designed formulas were given.  相似文献

A new method for studying mathematical models of discrete logical units based on functional equations is proposed. Representing Boolean functions in the class of formulas (circuits of functional elements with or without branching), we obtain the values of complexity indices in the number of characters, subformulas, and in the depth of a superposition formula (the number of functional elements and the circuit depth). The results are applied in the logical-computational approach to the intellectualization of synthesizing logical units on the basis of digital integrated circuits.  相似文献

We investigate the remainder of the approximation formula of a function fC[0,1] by means of a generalized Bernstein operator (1.3), depending on two nonnegative integer parameters, introduced by the author in 1984 in the paper [11]. The remainder is expressed in (2.1)–(2.2) by a formula generalizing the author's earlier representation (1.2) of the remainder in Bernstein's classical approximation formula. In (2.13)–(2.14) an expression is given for the remainder involving a linear functional (2.14) which is a convex combination of second-order divided differences.

Dictionary markup is one of the concerns of the Text Encoding Initiative (TEI), an international project for text encoding. In this paper, we investigate ways to use and extend the TEI encoding scheme for the markup of Korean dictionary entries. Since TEI suggestions for dictionary markup are mainly for western language dictionaries, we need to cope with problems to be encountered in encoding Korean dictionary entries. We try to extend and modify the TEI encoding scheme in the way suggested by the TEI. Also, we restrict the content model so that the encoded dictionary might be viewed as a database as well as a computerized, originally printed, dictionary. This revised version was published online in July 2006 with corrections to the Cover Date.  相似文献

We should follow Mark Olsen's lead and think with maximum ambition of the role of the computer in supporting literary research of the highest order. Thus the computer enables us to answer one of the great questions of literary criticism: how does a given writer contribute to the changing language? We can now chart the influence of given writers by correlating their words and phrasing with computerized dictionaries so as to produce profiles and histories of the way words have entered the language.Dennis Taylor is a professor of English at Boston College and a nineteenth century specialist.
