Húsek, Dušan ; Keyhanipour, A. ; Krömer, P. ; Moshiri, B. ; Owais, S. ; Snášel, V.
An innovative meta-search engine named WebFusion has been presented. The search system learns the expertness of every particular underlying search engine in a certain category based on the users' preferences according to an analysis of click-through behavior. In addition, an intelligent reranking method based on ordered weighted averaging (OWA) was introduced. The re-ranking method was used to fuse the results' scores of the underlying search engines. Independently, a progressive application of evolutionary computing to optimize Boolean search queries in crisp and fuzzy information retrieval systems was investigated, evaluated in laboratory environment and presented. In this paper we describe proposed incorporation of these two innovative recent methods founding an advanced Internet search application.

Implications resulting from finding information in the Internet in regard to relations between search engine and its user
Henych, Filip ; Sklenák, Vilém (advisor) ; Bělohoubková, Lenka (referee)
The aim of this work is to summarize the basic knowledge of ways to search the Internet and its usage. The work focuses on a description of search engines, as well as on description of expanded search options. It thinks out the credibility and recency of the web pages. It focuses on the role of a user as a searcher and the role of search engine as an output of relevant links. In this work, I tried to compare some search engines from the perspective of the relevance of outputs from different queries. Part of the work contains also a question survey focusing on the usage of search engines. It analyzes the problems of communication between the user and the search engine. The work is divided into three parts. In the first part, which contains the first and second chapter, I analyzed the basic ways of internet searching and described the main definitions related to internet searching. In the second part, I focused on the description of some search engines and I tested them by entering different queries.The last part contains the last two chapters. It pays attention to problems with the usage of search engines. It's concerned with credibility and recency of the information appearing on the websites and misusage of content to improve position in search engines. This part ends with a question survey among the users about different ways to use search engines.
