Computational Intelligence Techniques Driven Intelligent Agents for Web Data Mining and Information Retrieval

Abstract

The World Wide Web has added an abundance of data and information to the complexity of information for disseminators and users alike. With this complexity has come the problem of finding useful and relevant information. There is a need for improved and intelligent search and retrieval engines. Current search engines are primarily passive tools. To improve the results returned by searches, intelligent agents and other technology have the potential, when used with existing search and retrieval engines, to provide a more comprehensive search with an improved performance. This research provides the building blocks for integrating intelligent agents with current search engines. It shows how an intelligent system can be constructed to assist in better information filtering, gathering and retrieval. The research is unique in the way the intelligent agents are directed and in how computational intelligence techniques (such as evolutionary computing and fuzzy logic) and intelligent agents are combined to improve information filtering and retrieval. Fuzzy logic is used to access the performance of the system and provide evolutionary computing with the necessary information to carry out its search.

Kavosh: An Intelligent Neuro-Fuzzy Search Engine

“…The first method is a simple statistical algorithm in which the more a word occurs in a document, the higher rank it gets. The latter approach, however, uses a fuzzy approach [21] to evaluate and assign a score to a web page. The inputs to the fuzzy inference system, are the normalized value of term frequency in the document, position of the word, and number of weblinks to the page.…”

Hybrid Technique Based on Clustering for Crime Detection in Data Mining

“…DM refers the discovery of exciting know-how, consisting of patterns, institutions, changes, anomalies and substantial systems from large quantities of records saved in databases and different information repositories. [1] There has been an good sized increase in the crime inside the latest past. Crime deterrence has grow to be an upheaval task.…”

Captação de sinais antecipativos na web utilizando agentes inteligentes

“…A construção de um protótipo de agente inteligente de software será baseada na primeira forma descrita por Mohammadian (2004) para a fase de Inteligência Competitiva que passaremos a utilizar e a denominar de rastreamento.…”

“…Em Mohammadian et al (2004), os mecanismos de busca e recuperação de informação têm aumentado de maneira significativa sua capacidade, mas Jansen (2002( apud MOHAMMADIAN, 2004) afirma que, embora esses mecanismos tenham se tornado bastante sofisticados, eles não podem e não provêem assistência suficiente para os usuários na ação de localizar e filtrar a informação relevante desejada por ele.…”

“…Segundo o autor, o rastreamento é uma operação contínua no tempo que enfatiza a pesquisa ativa de informações em caráter antecipativo. Ela é garantida por pessoas que têm a missão de antecipar as informações de monitoramento estratégico (MOHAMMADIAN, 2004).…”
