Readings for Week 13
1. Web Search Engines:
This article is about the evolution of the search engine and how google, yahoo etc. search through millions of information and data constantly. This article discusses how web search engines are able to search through all of this data. They ignore a lot of low value data and there are a lot of confidential pages on the web that they cannot search. This would weed out a lot of stuff but there is still a lot of information on the web. Crawlers have a lot to decode and sort through so they often crash or burn out
2. Current Developments and Future Trends for the OAI protocol
OAI stands for Open Archives Initiative. It is used to create access for e-print articles but as expanded to other communities. This article was very repetitive. I got that the OAI did something with metadata and data harvesting but beyond that, I really didn't get it. This is another article that dropped a lot of big words but didn't really say much, at least for me.
3. The Deep Web: Surfacing Hidden Value
This article goes into the expansiveness of the web and how search engines very often just skim the surface of what's available. It seems very crazy that there is so much on the web that we never see. I just picture in the dark corners of the web, there's a balrog or two lurking or one of those fishes with lights hanging off of it's head. At first it seems like a really good idea to explore that unknown expanse of information but if it's not important or useful, is it really that imperative that we find it? We have information overload already (I experience this feeling everyday) and I don't really feel like adding to it.

Readings for Week 11...or perhaps it's 12 now..?
An Introduction to XML: XML, from reading the article, seems to be a way to show information on the web and share that information with others. It doesn't use tags like HTML and instead organizes information with elements. The article goes into what XML is used for and how to use it. XML tags are based on the actual format of the document so they are easier to understand. XML is ideal for database use, as mentioned in the article.
A Survey of XML standards part 1
This article is obviously a survey of information about XML. The website provides resources for the different versions of XML and the standards. There are lots of links to software that can help you with using XML. There are tutorials, videos, and references, most of the resources seem to be professional and technical about the actual workings of the software and applications. I didn't really understand a lot of it.
Extending your Markup
This article was a more straightforward discussion of XML. It explained the difference between XML and HTML. HTML is used for web layout while XML relates to the content of the data on the website. XML is also easier to read for humans, as well as computers. The article put it well when it gave the different examples of HTML and XML and showed that the first was more layout oriented while the second dealt more with structure.
XML Schema Tutorial
The last website was similar to the HTML tutorials we looked at in a previous week. The tutorials and explanations were helpful in understanding how XML works. I understand it a little better after looking at this website. XML seems to be more concerned with databases then HTML.
