摘要:

进化聚类算法被认为是最流行和最广泛使用的进化算法,在几乎所有领域的最小优化和实际问题。本文提出了一种新的进化聚类算法星型(ECA *)。此外,进行了一些实验,以评估ECA * 对五个国家的最先进的方法。为此,使用32个异构和多特征数据集,使用内部和外部聚类措施来检查其性能,并以操作框架的形式测量其性能对数据集特征的敏感性。结果表明,ECA * 克服了它的竞争技术方面的能力,找到正确的集群。基于其优越的性能,开发和适应ECA * 的本体学习具有重要的可能性。在从语料库中提取概念层次的过程中,形式背景的生成是一个非常耗时的过程。因此,形式上下文大小的减少导致去除不感兴趣的和错误的对,从而花费更少的时间来提取概念格和概念层次。在这一前提下,这项工作的目的是提出一个框架,以减少模糊的正式背景下,现有的框架,使用自适应版本的ECA *。在这两个框架下,使用维基百科的385个样本语料进行实验,研究了形式背景规模的减少,从而产生概念格和概念层次。使用概念格不变量对所得到的形式背景格进行评估。相应地,这两个格之间的同态保持了89%的质量,从而产生的概念层次结构的基本的,和减少的概念格继承了原来的结构关系。

英文摘要:

Evolutionary clustering algorithms have considered as the most popular and widely used evolutionary algorithms for minimising optimisation and practical problems in nearly all fields. In this thesis, a new evolutionary clustering algorithm star (ECA*) is proposed. Additionally, a number of experiments were conducted to evaluate ECA* against five state-of-the-art approaches. For this, 32 heterogeneous and multi-featured datasets were used to examine their performance using internal and external clustering measures, and to measure the sensitivity of their performance towards dataset features in the form of operational framework. The results indicate that ECA* overcomes its competitive techniques in terms of the ability to find the right clusters. Based on its superior performance, exploiting and adapting ECA* on the ontology learning had a vital possibility. In the process of deriving concept hierarchies from corpora, generating formal context may lead to a time-consuming process. Therefore, formal context size reduction results in removing uninterested and erroneous pairs, taking less time to extract the concept lattice and concept hierarchies accordingly. In this premise, this work aims to propose a framework to reduce the ambiguity of the formal context of the existing framework using an adaptive version of ECA*. In turn, an experiment was conducted by applying 385 sample corpora from Wikipedia on the two frameworks to examine the reduction of formal context size, which leads to yield concept lattice and concept hierarchy. The resulting lattice of formal context was evaluated to the original one using concept lattice-invariants. Accordingly, the homomorphic between the two lattices preserves the quality of resulting concept hierarchies by 89% in contrast to the basic ones, and the reduced concept lattice inherits the structural relation of the original one.
