EIR 5th lessons on practical 4 & 5, we learnt new internet research facilities which is Meta search engines and other subject directories.
Meta Search Engines also known as metacrawlers or multi-search engines. It searches key words simultaneously to several search engines such as yahoo and google as they do not have their own database of web pages.It eliminates and comes up with the prominent key words as well as the larger number of potentially higher quality references.
Subjects directories, also known as subject catalogs.It searches in topical lists arranged in a hierarchical way. It tells the user the key words and availability of the potential website.I feel metacrawlers are much more useful than search directories as more relevant websites to help me with my search queries.
Using wiki is useful as we can exchange views and learn something new with different ideas and views. I feel that through wiki's, it can develop and widen our thinking with useful ideas that are being exchanged.
