W12 Readings

Web Crawling, Page Ranks, Deep Web and metadata harvesting were interesting read for me. I imagined the databases as the oil pumps with the ocean of the data around it. The graphic information were helpful, it allowed me to understand how deep the web is. Millions of the data floating in the cyberspace, to access them all is a challenge. Page ranks certainly makes sure the information and the websites are still there, this also might mean the website have not updated and it shows the limitation- if the word were popular association during certain years. It also depends on the importance of the data to the user. If the user is not satisfied, more time devoted to digging through the search engine.
