It’s been empirically observed by the authors that inserting tags that have been used to describe the two major search engines’ results enhances the total results, but what’s also interesting to observe is which engine gives which set of tag results.
A visual separation of the tags assigned to different engine’s results helps making such a comparison. The user can use this option by enabling a distinguishing colored circle around each tag denoting the tag’s origin.
Notable differences in google’s and yahoo’s resulting tags can be attributed primarily to their different retrieval methods and secondly to the differences of their users who may collect their del.icio.us bookmarks from either of them.
Moreover, since tictag supports comparative searches it’s interesting to take a look into the differences of results of synonymous words. It’s been said that the meaning of a word is formed in its use. So what do the different resulting tag clouds look like and how much do they divert?
