ERM, I think its time for Practical 4 & 5

Week 4 to 5, UIR assignment 1.

Lets start.

Topic: Discuss the developments of Internet social network services.
Why: Namely because I participate in many of the social networking websites.
What: 3 different search facilities.
Keyword: Friends Networking
Who: Google, Yahoo Directory and Meta Crawler.

Google:

• Massive Database.
• Plenty of results.
• Allows phrase searching to reduce the number of results.
• Many other advance capabilties such as operator usage etc.
• Has proprietary PageRank technology to rank pages.

Meta Crawler:

• Meta Search Engine.
• No own database.
• Searches other search facilities' databases.
• Consolidates results returned before presenting to user.
• As accurate as Google, sometimes return even better results.

Yahoo Directory:

• Subject Directory
• Complied by human.
• Suitable for familiar or a particular topic.
• Mostly accurate but does not return a variety of results like other two.

How:

• 1st; Google - Innovative features and PageRank system help to yields much more comprehensive results.
• 2nd; MetaCrawler - Alternative to Google due to its similarities and multiple sources.
• Last: Yahoo Directory - Just a search of results already categorized in a hierarchy.
