Metatags

We've had a meeting with Lars and had some really long and interesting discussions about the project. One of the things the player is/was lacking, was some sort of continuity when browsing the videos.

We've worked on a solution for that by using the keywords(metatags) from all the videos. The system will now find relevant keywords and list them at the bottom of the results list. It will also look for the keywords in the different videos' descriptions and replace the words with hyperlinks to searches for the word. It works like this:

1. User searches for "lost".
2. A list of 4 results show up.
3. The system collects all the keywords from all the videos and finds out if any of them show up more than once. If a keyword shows up more than once it is associated to more than one of the results and will be considered a relevant keyword.
4. Since David is often lost, "David" will be considered a relevant keyword as it is associated to several of the results for "lost".
5. The system pulls out all info about the results (title, image, description etc).
6. The system will go through all of the descriptions and compare all the words with the keywords.
7. If a word in a description matches a keyword, the word will be replaced with a hyperlink to a search for the keyword.
8. All relevant keywords will be listed in the bottom of the search results page.

The system seems to work very well and actually quite fast despite the tons of data processing. We still have to test it with a lot more videos too see the actual performance.
