Who said that ‘Heroes’ had anything to do with cheerleading? May 26, 2008

In the previous post, I was talking about the need of ontologies to define the area of interest of the course, so that we could afterwards match it with the metainformation attached to TV programs. So, here we come to the conclusion that TV programs should be semantically annotated, too.
But who performs such annotation?
It would be nice that the same people designing the course also annotated the programs. This, though, is impractical and maybe impossible, and the original idea is to achieve the matching automatically, so that new programs can be added to the course without new revision.
The simplest way would consist in letting the TV channels include this information by themselves. But here we face a potential problem: TV providers might not worry about t-learning, spending little time and effort in doing this correctly – we could find wrong tags, scarce or even no information at all, worse than using syntactical search.
The approach that Rey et al. propose is the use of social tagging, and it is, in fact, the main contribution of the article of discussion for this blog. Being the actual viewers the ones that assign tags to the programs, the most popular tags for a specific one should be highly accurate.
In the next posts we’ll have a look on social tagging, which is called folksonomy, and how it can be applied to t-learning in practice.
