1 Introduction
Standard Web search services are quite useful in their own right, but are
far from ideal. Search engines retrieve web pages which contain information
relative to the subject which the user queries. Meta search unlike standard
search, utilizes many di erent search systems to provide results. The Meta
Search Engine (MSE) is a system that enables a meta search[3].
Meta search engines are Web services that receive user queries and dispatch
them to multiple crawl-based search engines (also called component
engines)[1]. Once all the results are returned from the component search engines,
they are merged into a single ranked list. The advantage of MSEs are
their ability to combine coverage across multiple search engines thus allowing
them to reach the Deep Web. MSEs therefore work at a much higher level
than the standard web search engine.
There are two distinct steps in creating a MSE. Firstly searching through
the deep web to collect results and secondly to both merge and rank those
results. Thus the algorithm used in the ranking and merging process is
critical because it has a direct impact on the e ectiveness of the MSE. This
report will focus on discussing di erent strategies to integrate the results
received from multiple search engines for use in a MSE.
