Abstract

Purpose – Syntax-based text classification (TC) mechanisms have been overtly replaced by semantic-based systems in recent years. Semantic-based TC systems are particularly useful in those scenarios where similarity among documents is computed considering semantic relationships among their terms. Kernel functions have received major attention because of the unprecedented popularity of SVMs in the field of TC. Most of the kernel functions exploit syntactic structures of the text, but quite a few also use a priori semantic information for knowledge extraction. The purpose of this paper is to investigate semantic kernel functions in the context of TC. Design/methodology/approach – This work presents performance and accuracy analysis of seven semantic kernel functions (Semantic Smoothing Kernel, Latent Semantic Kernel, Semantic WordNet-based Kernel, Semantic Smoothing Kernel having Implicit Superconcept Expansions, Compactness-based Disambiguation Kernel Function, Omiotis-based S-VSM semantic kernel function a...
语义核函数的性能和准确性分析
近年来,基于语法的文本分类(TC)机制已经被基于语义的系统所取代。基于语义的TC系统在考虑术语之间的语义关系计算文档之间的相似性的场景中特别有用。由于支持向量机在TC领域的空前普及,核函数受到了广泛的关注。大多数核函数利用文本的句法结构,但也有不少核函数利用先验语义信息进行知识提取。本文的目的是研究语义核函数在语义翻译中的应用。设计/方法/方法-本工作介绍了七个语义核函数的性能和准确性分析(语义平滑核,潜在语义核,基于语义wordnet的核,具有隐式超概念展开的语义平滑核,基于紧凑性的消歧核函数,基于omiotis的S-VSM语义核函数…
