متن کاملStudy of Design Issues on an Automated Semantic Annotation System
The semantic annotation process turns ordinary HTML web pages into machine-understandable semantic web pages. We have proposed a semantic annotation system to automate annotation of web pages by ontologies. In this paper, we present a study of five design issues on this system, which include: (1) the covering of web pages; (2) the general paradigm of annotation process; (3) the measurements of ...
