傳統(tǒng)的上下文預(yù)測是在單用戶的上下文基礎(chǔ)上進行的，忽視了實際普適計算環(huán)境中由于用戶交互活動導(dǎo)致的上下文變化因素。為了合理、有效地解決上述局限性問題，該文提出基于交互上下文的預(yù)測，給出交互上下文及交互上下文預(yù)測的概念，以及相關(guān)的建模、推
理算法。

【Abstract】Traditional context prediction approach is to predict context based on the single user’s context records, but in real ubiquitous or
pervasive computing environment, the change of user’s context is mostly due to interactive activity of users. In order to solve the problem above, this
paper presents a context prediction approach based on interactive-context, gives the concepts of interactive-context and interactive-context
prediction, and introduces the modeling of interactive-context and the reasoning algorithm of interactive-context prediction.
【Key words】interactive-context; interactive-context model; context prediction.
