Preference-Based Query Personalization
نویسندگان
چکیده
In the context of database queries, computational methods for handling preferences can be broadly divided into two categories. Query personalization methods consider that user preferences are provided as a user profile separately from the query and dynamically determine how this profile will affect the query results. On the other hand, preferential query answering methods consider that preferences are explicitly expressed within queries. The focus of this chapter is on query personalization methods. We will first describe how preferences can be represented and stored in user profiles. Then, we will discuss how preferences are selected from a user profile and applied to a query.

Personalization of Queries based on User Preferences
Query Personalization is the process of dynamically enhancing a query with related user preferences stored in a user profile with the aim of providing personalized answers. The underlying idea is that different users may find different things relevant to a search due to different preferences. Essential ingredients of query personalization are: (a) a model for representing and storing preference...
متن کاملOptimizing Preference Queries for Personalized Web Services
Personalization of Web services requires a powerful preference model that smoothly and efficiently integrates with standard database query languages. We make the case for preferences as strict partial orders, supported in Preference SQL and Preference XPATH. Performance of Web services will crucially depend on various architectural design decisions. We pointed out that a central server architec...

متن کاملTop-k Ranking of Preference Query Results for XML Based on Similarity of Contextual States ⋆
The ranking method of XML preference query results is an important issue. For user’s preference query request, the query results are often user’s interested information. In order to satisfy the user’s personalized query requirements, this paper proposes the XML contextual preference model. When a user submits a query request, the user’s preference query results depend on the contextual conditio...
متن کاملAlgebraic Optimization of Relational Preference Queries
The design and implementation of advanced personalized database applications requires a preference-driven approach. Representing preferences as strict partial orders is a good choice in most practical cases. Therefore the efficient integration of preference querying into standard database technology is an important issue. We present a novel approach to relational preference query optimization b...
