信息检索中的形式概念分析

Formal Concept Analysis for Information Retrieval

Abderrahim El Qadi, Driss Aboutajedine, Yassine Ennouary

摘要:

在本文中,我们描述了一种机制,以提高信息检索(IR)在Web上。该方法是基于形式概念分析(FCA),它是在查询过程中的语义关系,并允许重组,在一个概念格的形状,由搜索引擎提供的答案。提出了一种基于伽罗瓦格的增量式算法。该算法允许对数据源进行正式的聚类,并将其翻转的结果按相关性的顺序进行分类。在聚类过程中利用了相关性的控制,通过在图像处理领域中引入本体来改进聚类结果,并对用户查询进行了重新定义,使得能够给出更多的相关文档。

英文摘要:

In this paper we describe a mechanism to improve Information Retrieval (IR) on the web. The method is based on Formal Concepts Analysis (FCA) that it is makes semantical relations during the queries, and allows a reorganizing, in the shape of a lattice of concepts, the answers provided by a search engine. We proposed for the IR an incremental algorithm based on Galois lattice. This algorithm allows a formal clustering of the data sources, and the results which it turns over are classified by order of relevance. The control of relevance is exploited in clustering, we improved the result by using ontology in field of image processing, and reformulating the user queries which make it possible to give more relevant documents.
