Semantics web: fun and semantics aware applications. (6E)

Research on the semantics web:
• http://www.youtube.com/watch?v=OGg8A2zfWKg (this video is mentioned on the horizon report)
Summary: the video gives a brief introduction to the semantics web. I understood the basic meaning of semantics – it is the meaning of the sentences and words.
• The horizon report:
Summary: a good example on the horizon report was when a word that has more than one meaning such as ‘turkey’. When entered into a search engine, (a sentence with this word such as the history of turkey) it could give results on the bird, the country and the food showing the computer has only searched the word, not its meaning.
• http://computer.howstuffworks.com/semantic-web.htm
Summary: explains the difference between human brain processing and computer processing. It is explained that computers cannot understand the semantics of phrases and commands entered into their search engines etc. They search based on syntax and hence irrelevant search results can be obtained.
METADATA is an important word mentioned on this article. It means to know about the data rather than the data itself, and is described as an extension to the World Wide Web.

Another example on this site was when a movie is ordered for on the web. There could be several conditions on this purchase such as you want the lowest price available, don’t want to wait too long for delivery, you want a firsthand product and widescreen. There are two things that can be done here,
1. You could manually look for all these criteria and hope to find a perfect product. This would take a long time and would be a waste of your time.
2. The second option is more feasible. With the Semantic Web, you could enter all these into a computer ‘agent’ which would look for the best option and place your order for you.

Summary: an important point of this article is that the Semantic Web is about two things:
1. The language of the data and how it relates to real world objects.
2. Formats for integration and combination of data that has been drawn from different sources.
Notes on the movie
Netgened: I worked with my team mates in certain discussions and posted some good links to information about the subject.
Grownupdigital: gotten in touch with my team mates.
