In this paper we present a framework that extracts meaningful knowledge from microposts shared in social platforms in order to build user profiles. This process involves different steps for the analysis of such microposts (extraction of keywords, named entities and their matching to ontological concepts) and their weighting. The concept weighting involves different scores, such as sentiment analysis...
Web pages are typical semi-structure data. Some tree-based models have been proposed to describe the semantic content structure of web pages in order to facilitate further content analysis. However, most existing models only present the segmentation hierarchy of content blocks rather than the semantic relationships among them. In this work, we propose a novel web page semantic structure model, called...
The author discusses the development of new Information Communications Technologies (ICT) in the areas of e-Learning, e-Health, e-Government, e-Journalism, etc. The current Web 2.0 combined with the Semantic Web technologies provide support to creation of social networks, content retrieval and analysis, which creates foundation for the future fully automated cyberspace.
The paper presents an ontological approach for enabling personalized searching framework facilitating the user access to desired contents. Through the ontologies the system will express key entities and relationships describing resources in a formal machine-processable representation. An ontology-based knowledge representation could be used for content analysis and concept recognition, for reasoning...
Social networks have recently attracted much attention for their importance to the semantic Web. Several methods exist to extract social networks for people from the Web based on co-occurrence information. This paper proposed a content analysis based method for automatic obtaining social networks among various entities from Chinese event-based news stories. First, the input articles are annotated...
The MultimediaN concert-video browser demonstrates a video interaction environment for efficiently browsing video registrations of pop, rock and other music concerts. The exhibition displays the current state of the project for developing an advanced concert-video browser in 2007. Three demos are provided: 1) a high-level content analysis methodology for modeling the "experience" of the...
