商品描述

Among the search tools currently on the Web, search engines are the most well known thanks to the popularity of major search engines such as Google and Yahoo!. While extremely successful, these major search engines do have serious limitations. This book introduces large-scale metasearch engine technology, which has the potential to overcome the limitations of the major search engines. Essentially, a metasearch engine is a search system that supports unified access to multiple existing search engines by passing the queries it receives to its component search engines and aggregating the returned results into a single ranked list. A large-scale metasearch engine has thousands or more component search engines. While metasearch engines were initially motivated by their ability to combine the search coverage of multiple search engines, there are also other benefits such as the potential to obtain better and fresher results and to reach the Deep Web. The following major components of large-scale metasearch engines will be discussed in detail in this book: search engine selection, search engine incorporation, and result merging. Highly scalable and automated solutions for these components are emphasized. The authors make a strong case for the viability of the large-scale metasearch engine technology as a competitive technology for Web search. Table of Contents: Introduction / Metasearch Engine Architecture / Search Engine Selection / Search Engine Incorporation / Result Merging / Summary and Future Research

商品描述(中文翻譯)

在目前的網路搜尋工具中,搜尋引擎因為 Google 和 Yahoo! 等主要搜尋引擎的普及而最為人所知。儘管這些主要搜尋引擎非常成功,但它們確實存在嚴重的限制。本書介紹了大規模的元搜尋引擎技術,這項技術有潛力克服主要搜尋引擎的限制。基本上,元搜尋引擎是一種搜尋系統,支持通過將接收到的查詢傳遞給其組成的搜尋引擎,並將返回的結果聚合成一個單一的排名列表,來實現對多個現有搜尋引擎的統一訪問。一個大規模的元搜尋引擎擁有數千個或更多的組成搜尋引擎。雖然元搜尋引擎最初是因為能夠結合多個搜尋引擎的搜尋覆蓋範圍而受到關注,但還有其他好處,例如獲得更好和更新的結果以及訪問深層網路(Deep Web)的潛力。本書將詳細討論大規模元搜尋引擎的以下主要組成部分:搜尋引擎選擇、搜尋引擎整合和結果合併。這些組成部分的高度可擴展和自動化解決方案將受到重視。作者強調大規模元搜尋引擎技術作為網路搜尋的競爭技術的可行性。
