Managing contextual preferences
To handle the overwhelming amount of information currently available, personalization systems allow users to specify through preferences which pieces of data interest them. Most often, users have different preferences depending on context. In this paper, we introduce a model for expressing such contextual preferences. Context is modeled using a set of hierarchical attributes, thus allowing cont...
متن کاملContextual Preferences
The validity of semantic inferences depends on the contexts in which they are applied. We propose a generic framework for handling contextual considerations within applied inference, termed Contextual Preferences. This framework defines the various context-aware components needed for inference and their relationships. Contextual preferences extend and generalize previous notions, such as select...
متن کاملContextual Database Preferences
As both the volume of data and the diversity of users accessing them increase, user preferences offer a useful means towards improving the relevance of the query results to the information needs of the specific user posing the query. In this article, we focus on enhancing preferences with context. Context may express conditions on situations external to the database or related to the data store...

User preferences play an important role in database query personalization since they can be used for sorting and selecting the objects which most ful ll the user wishes. In most situations user preferences are not static and may vary according to a multitude of user contexts. Automatic tools for extracting contextual preferences without bothering the user are desirable. In this paper, we propos...
متن کاملClassification-based Contextual Preferences
This paper addresses context matching in textual inference. We formulate the task under the Contextual Preferences framework which broadly captures contextual aspects of inference. We propose a generic classificationbased scheme under this framework which coherently attends to context matching in inference and may be employed in any inferencebased task. As a test bed for our scheme we use the N...
