Re: web to semantic web : an automated approach

Buts whats the incentive for web site owners to mark up their website with
semantic data. Few days back i was reading some study conducted by Opera
browser team that said that most of the html generated by websites is not
even valid. How can we hope them to create correct semantic data. Also what
happens to lot of other user submitted content(blogs, wikis etc ) ?

Instead why not create a mechanism to automatically convert web data to
semantic data. Opencalais.com is already doing it on small domain, why
can't/shouldn't we do it at web's scale ?


*John *: I realized that you are form BBN. In case you are aware, can you
please tell us from your experience about the state of NLP ? To what extent
the current best NLP systems are capable of extracting infroatmion from
unformatted text ? And what are the hopes for the future to  overcome the
curent shortcomings in NLP systems?
