One method that Internet users utilize to collaborate is annotating web content. Users can share knowledge, ideas, opinions, and skills in this way. Annotation systems can also be used for online learning. This paper proposes applying an annotation system to knowledge enhancement (network topic) by connecting the annotations to information resources and sharing the knowledge with others. Users can extract the most crucial terms from the selected online text using the annotation tool, which loads relevant YouTube videos and quizzes based on selected terms. In addition, users have the option to recommend terms to their friends as a way to spread information. The experimental test reflects promising knowledge-gaining, sharing, and dissemination results.
