Notas do Editor
- We develop ontologies to provide common understanding of information structure. If I have an ontology that contains the terminologies of different websites on fish, I can develop applications that can extract infor from all of these sites. Mian point of SemWeb: Many applications eg require geographical info. If one group of researchers develops such an onto, then others who have a need for it theijr domains can reuse it. Also, if need to builkd a large onto, can use existing ones ot take parts of differeent ones and merge them together as a starting point. Make explicit domain assumptuions: enables people to learn the terms for the domain. FS portal, BSE symptoms query From a practical point of view, it is easier to make changes when knowledge changes. Prion causes mad cow disease. Not sure at the moment but await later confirmation. Too difficult if knowledge is hard coded into a program. Also has to do with reuseability: don’t want to customize an ontology too closely to a specific application. Have an onto on biblio metadata. I could use it in an online bookstore to help with customer shopping, or I could use it for multihost searching of digital libraries.
