Most recommendation methods are "hard-wired" into the system and support only fixed recommendations. The purpose of this demo is to show the expressivity of flexible recommendation workflows, how flexible recommendations can be processed over relational data, and to show flexible recommendations in action through a real system used for course planning.
We study the following problem: A data distributor has given sensitive data to a set of supposedly trusted agents (third parties). Some of the data is leaked and found in an unauthorized place (e.g., on the Web or somebody's laptop). The distributor must assess the likelihood that the leaked data came from one or more agents, as opposed to having been independently gathered by other means. We propose...
Privacy, preservation and performance ("3 P's") are central design objectives for distributed data management systems. However, these objectives tend to compete with one another. This paper presents a model for describing distributed data management systems, along with a framework for measuring the privacy, preservation and performance offered by such systems. The framework enables a system...
Objects are often organized in a hierarchy to help in managing or browsing them. For example, products in a store can be divided by type (electronics, clothes, books, ...) and then by brand (Sony, Epson, Dockers, ...). Web pages at a site can also be placed in a hierarchy. For instance, a French tourist site may have categories cities, history, hotels, tours; within the cities category we have pages...
Entity resolution (ER) matches and merges records that refer to the same real-world entities, and is typically a compute-intensive process due to complex matching functions and high data volumes. We present a family of algorithms, D-Swoosh, for distributing the ER workload across multiple processors. The algorithms use generic match and merge functions, and ensure that new merged records are distributed...
In recent years, social Web sites have become important components of the Web. With their success, however, has come a growing influx of spam. If left unchecked, spam threatens to undermine resource sharing, interactivity, and openness. This article surveys three categories of potential countermeasures - those based on detection, demotion, and prevention. Although many of these countermeasures have...
Large-scale competitive P2P networks are threatened by the non-cooperation problem, where peers do not forward queries to potential competitors. Non-cooperation will be a growing problem in such applications as pay-per-transaction file-sharing, P2P auctions, and P2P service discovery networks, where peers are in competition with each other to provide services. Here, the authors showed how non-cooperation...
Our system suggests likely identity labels for photographs in a personal photo collection. Instead of using face recognition techniques, the system leverages automatically available context, like the time and location where the photos were taken. Based on time and location, the system automatically computes event and location groupings of photos. As the user annotates some of the identities of people...
