Implementing an internet image search service based on the AJAX web programming techniques

Abstract

Due to the extremely rapid growth of the web, search engines cannot spider all the new pages at the same time or with the same priority. Besides, the search engines index their catalogues with different algorithms, having as a result, different response time in updating their directories. Consequently, the user may lose some useful information resources if he chooses to use only one search service. Thus, the user has to resubmit his queries to more search engines, adding in this way, to a process that is already time-consuming [11]. Using a meta-search engine, additional information is provided, without the need to know the query language for the search services that contribute to the search. However, in this kind of retrieval a large amount of inappropriate and useless information is often returned to the user, especially when requiring images. © 2008 Springer-Verlag Berlin Heidelberg.
