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.
2 Meta Search Engine System
In order for us better understand result integration strategies, we need to take a look the science involved in creating a MSE. These can also be considered strategies which help the MSE return better search results. There are three components to take into consideration when building a MSE these include search engine selection,result extraction and result integration.
2.1 Search Engine Selection
In order for the MSE to chose which search e...

After "asking the question" the next step is to "Identifying the Important Factors". There can be a broad ranges of factors from simplistic to complex. There are an unlimited number of factors that could be used for consideration but some of the common themes to are the following (Salkind, 2012):
Introduction With today’s rate of development in technology, there has also been an immense increase in global information sharing. Innovations in technology and design seem to be emerging in the market almost every month. One of the key aspects of any business is to gather, organize and efficiently apply this information. According to Antonic (2005), economic assets are fast becoming of secondary importance in the market as companies ascribe more importance to intellectual capital. With the right application of knowledge management methods, companies can achieve a competitive advantage by managing the immense amount of information available (Balanced Scorecard Institute, 2002).

"Although fully searchable text could, in theory, be retrieved without much metadata in the future, it is hard to imagine how a complex or multimedia digital object that goes into storage of any kind could ever survive, let alone be discovered and used, if it were not accompanied by good metadata" (Abby Smith). Discuss Smith's assertion in the context of the contemporary information environment

Search engines have many capabilities from using key words or phrases to find what you are looking for to using general statements to browse the web. But what exactly is a search engine? Search engines are huge databases of web page files that have been assembled automatically by machine. There are two types of search engines. One type is the individual search engine. This type of search engine compiles its information on to its own database making it accessible when you use that particular engine. It does not use any other engine?s information to help with your search. Then there are the meta-searchers which do not have their own databases. They use a combination of individual search engine?s information simultaneously, from a single site and using the same interface. Meta-searchers provide a quick way of finding out which engines are retrieving the best results for you in your search. There are two ways that Meta-searchers show their results. Most use a single list which display multiple-engine search results in a single merged list and had removed all the duplicate entries from the list. The second way that they display their results is through multiple lists. These are separate lists in which are displayed as they are received from each engine leaving the duplicate entries on the list.
