A methodology for content filtering based on ontology similarity is presented, which uses Domain Ontology to describe the characteristic of knowledge of a specific domain. By analyzing the context of the Word of Concern (WoC), the justifiability and accuracy of filter is improved. Firstly, a content ontology based on Domain Ontology is defined, including WoCs and their context constrain rules. Secondly,...
In recent years, many researchers have paid attention to using the existing wireless local area network infrastructure to estimate position. There are two kinds of signal-strength-based modeling for WLAN positioning system: propagation modeling and fingerprinting modeling. The propagation modeling can not have high positioning accuracy; and the fingerprinting modeling will take great effort and time...
Respecting an interactive context involving multiple participants, dynamic characteristics of their activities will cause situations not faithfully described in a static method. In particular, the goal that represents the meanings of activities (equally as changes on situations), is far beyond the scope of ontology languages, such as the OWL. Then, we formalize activities as a sequence of context...
