内容适配中基于本体的传输上下文模型

Model of delivery context based on ontology for content adaptation

在内容适配的研究中,传输上下文的描述语言得到了广泛的关注,然而现有的描述语言在语义表达能力和用户偏好描述方面存在不足。为此提出了一种基于本体的传输上下文模型,通过将本体引入建模过程,提高了模型的语义表达能力和用户偏好的描述能力,较好地满足了e-learning背景下的内容适配的需求。

To realize universal multimedia access, researches propose content adaptation techniques in which the technique of delivery context description has attracted much more attentions. However, the existed techniques of context description are lack of the ability of semantic presentation and expression of user preference. Facing the music ,this paper proposed a model of delivery context based on ontology. By introducing ontology theory to the modeling process, the model was equipped with good features in respect of semantic presentation and expression of user preference, which would meet the requirement of content adaptation in e-learning environment prettily.
