Search engines and Web dynamics

Computer Networks, 2002
Abstract In this paper we study several dimensions of Web dynamics in the context of large-scale Internet search engines. Both growth and update dynamics clearly represent big challenges for search engines. We show how the problems arise in all components of a reference search engine model.

Web Mining in Thematic Search Engines

2005
In the present chapter we report on some extensions on the work presented in the first edition of the Encyclopedia of Data Mining. In Caramia and Felici (2005) we have described a method based on clustering and a heuristic search method- based on a genetic algorithm - to extract pages with relevant information for a specific user query in a thematic ...

Untangling Web Search Engines

Journal of Hospitality & Tourism Education, 1999
Search engines provide a basis for identification and retrieval of specific internet resources based on selected key words. In essence, the same software used to index the Internet can also be employed to catalog the content of various web sites. A search engine enables the user to submit queries and interact with databases to determine which, if any ...

A CLIR interface to a web search engine

Proceedings of the 28th annual international ACM SIGIR conference on Research and development in information retrieval, 2005
Medical document retrieval presents a unique combination of challenges for the design and implementation of retrieval engines. We introduce a method to meet these challenges by implementing a multilingual retrieval interface for biomedical content in the World Wide Web. To this end we developed an automated method for interlingual query construction by

Another Face of Search Engine: Web Search API’s

2008
Since search engine development requires building an index which is a tedious and space consuming process. Now-a-days all major search engines provide developers access to their resources through a set of APIs. In this paper we try to answer the following questions. What differences exist between search engines and their associated search APIs?

Approximate Keyword Search in Web Search Engines

2006 1st International Conference on Digital Information Management, 2007
We present a new index method to provide approximate keyword search in search engines. Our approximate keyword matching adopts a new similarity measurement called Listance model, which is a variation of the LCS (longest common subsequence) model. Two keywords are considered approximately matched, if their Listance is no more than a predefined parameter

Mashups for Web Search Engines

2013
Current practice in looking for information on the web states that searchers rely on large-scale web search engines to get assistance. The quality of the search results is analogous to the ability of the searchers to accurately express their information needs as keywords in the search engine’s input box.

The infocious web search engine [PDF]

Special interest tracks and posters of the 14th international conference on World Wide Web - WWW '05, 2005
In this paper we present the Infocious Web search engine [23]. Our goal in creating Infocious is to improve the way people find information on the Web by resolving ambiguities present in natural language text. This is achieved by performing linguistic analysis on the content of the Web pages we index, which is a departure from existing Web search ...
