Algorithmic Challenges in Web Search Engines
In this paper, we describe six algorithmic problems that arise in web search engines and that are not or only partially solved: (1) Uniformly sampling of web pages; (2) modeling the web graph; (3) finding duplicate hosts; (4) finding top gainers and losers in data streams; (5) finding large dense bipartite graphs; and (6) understanding how eigenvectors partition the web.
متن کاملScalability Challenges in Web Search Engines
Continuous growth of the Web and user bases forces web search engine companies to make costly investments on very large compute infrastructures. The scalability of these infrastructures require careful performance optimizations in every major component of the search engine. Herein, we try to provide a fairly comprehensive coverage of literature on scalability challenges in large-scale web searc...
متن کاملWeb Mining in Search Engines
Given the rate of growth of the Web, scalability of search engines is a key issue, as the amount of hardware and network resources needed is large, and expensive. In addition, search engines are popular tools, so they have heavy constraints on query answer time. So, the efficient use of resources can improve both scalability and answer time. One tool to achieve these goals is Web mining. Web mi...
متن کاملCredibility in Web Search Engines
Web search engines apply a variety of ranking signals to achieve user satisfaction, i.e., results pages that provide the best-possible results to the user. While these ranking signals implicitly consider credibility (e.g., by measuring popularity), explicit measures of credibility are not applied. In this chapter, credibility in Web search engines is discussed in a broad context: credibility as...
متن کاملWorld Wide Web Search Engines
Copyright © 2003, Idea Group Publishing. ABSTRACT The World Wide Web now holds more than 800 million pages covering almost all daily issues. The Webs fast growing size and lack of structural style present a new challenge for information retrieval. Numerous search technologies have been applied to Web search engines; however, the dominant search method has yet to be identified. This chapter pro...
