Mamma.com is created in 1996 as a master thesis. This site owned and operated by Copernic.Inc. Its provide a variety of engines ,directorie
s, and content sites, compiles their results invirtual database ,eliminates duplicates and display the result in a uniform manner according to relevance. Mamma .com's ability to give a best result that available from search sources because it searches a series of other engine of other search. It likes using many search engines in the same time (including other search engine like yahoo, Google).Mamma.com also searches about jobs, videos, shops, travel, yellow pages and white pages.
Yahoo.com is search engine like mamma.com .Yahoo! search not only web article but its helps user to find an information from the content like news, images, mail (provides free email, picture sharing, spam protection and etc.), maps, travel, music, games, and sport. With Yahoo! Answers, users can find answer from around the web.
Google scholar is an example of a search engine that searches specifically for scholarly literature. It is fast and easy to use and can lead us to hundred of relevance articles. This search engine also same like the others because it is also provides all information about academic. Google scholar can search about article, peer-reviewed journal, and academic books, also academic publishers.
Eric Digest is provides one way to access the ERIC DIGEST that produce by Eric clearing house system. Eric digest are:-a) Short report (1,000 - 1,500) on topics that related to education field. There are variety of topics was covered. For instance, teaching, learning, libraries, charter school, special education, higher education, home schooling and etc.
b) This site is targeted specifically for teachers, administers, policymakers, and other practitioners and also useful for educational community.
Similarities
From what I'm see, each of these sites have a similarity between each other. Yahoo! Search, Google Scholar and Mamma.com are search engine web. Users can use these four web sites as the search engine to find their information that they need. Other than that, Yahoo! and Google have a same content such as both provide an email account for users. So, users can use this services to exchange their information with other friends spread the world. Last but not least, these entire search engine become an informative tools for user especially student to get their information.
Differences
There are some differences between this four of search engines. For instance, Mamma.com and Eric Digest provided an article that related to the topic only. Both of this search engines have less hit list then Google and Yahoo because they only search information that really-really related to topic and make our work become easier. But for me, Mamma.com is good because it give us a lot of information in the same way. By using metasearch on Mamma.com, it will search a series of search engines from other search in the same times. So, it's faster than other search engines. Mamma.com, Google scholar and eric digest is more on academic search such as journal, literature book and many more .However, Yahoo! Search apply variety services on their pages and not only focused on academic things.
