Starting with the Netflix Prize, which fueled much recent progress in the field of collaborative filtering, recent years have witnessed rapid development of new recommendation algorithms and increasingly more complex systems, which greatly differ from their early content-based and collaborative filtering systems. Modern recommender systems leverage several novel algorithmic approaches: ...

This article analyzes a proprietary log of printed web pages and aims at answering questions regarding the content people print (what), the reasons they print (why), as well as attributes of their print profile (who). We present a classification of pages printed based on their print intent and we describe ...

We increasingly get our news, entertainment, and information via computers, tablets, and phones. The proliferation of digital content in a plurality of forms (including e-news, movies, and online courses), along with the popularity of portable devices has created immense opportunities as well as challenges for systems in order to provide ...

Publisher: IEEE Educational Activities Department
Citation Count: 2

In this paper, we argue that preference-aware query processing needs to be pushed closer to the DBMS. We introduce a preference-aware relational data model that extends database tuples with preferences and an extended algebra that captures the essence of processing queries with preferences. Based on a set of algebraic properties ...

As web and mobile applications become more sensitive to the user context, there is a shift from purely off-line processing of user actions (log analysis) to real-time user analytics that can generate information about the user context to be instantly leveraged by the application. Ubeone is a system that enables ...

In implementing preference-aware query processing, a straightforward option is to build a plug-in on top of the database engine. However, treating the DBMS as a black box affects both the expressivity and performance of queries with preferences. In this paper, we argue that preference-aware query processing needs to be pushed ...
