This week we were to look at how Google, Yahoo and DMOZ, or The Open Directory, three different search engines, determine relevancy rankings. The best thing that I got out of this exercise was the discovery of DMOZ. When I saw the name, Open Directory, it rang a bell, but I had never tried it. I was pleasantly surprised when the search words that I entered for each search engine turned up the best results in DMOZ.
"Ancient +Egypt +grade +7 +resources" yielded 20 educational sites in DMOZ, and in Google and Yahoo my search yielded mainly irrelevant results. Because I used Boolean logic (adding "+") to narrow down my results, the number of websites was considerably lower than if I had simply typed in a question or a key phrase with none of the following symbols: +, -, "".
In the discussion forum this week many of my classmates shared their frustration with the Metadata articles, but they also shared some kid-friendly search engines such as: Kids' Search Tools, Kids Click. I would also like to share SweetSearch as a student-friendly search engine. Joyce Valenza says this about Finding Dulcinea, which operates SweetSearch: "What does FindingDulcinea do right? It organizes. It evaluates. It creates context. It is conscious of design. It gets media."
Try out your next query on SweetSearch and let me know what you think!
If you are in a French Immersion school/library and are looking for a good French language search engine, try out La Toile du Québec. I've gotten good results for my searches with this search engine.
