The estimation of the perceived tempo is required in many MIR applications. However, automatic tempo estimation itself is still an open problem due to the insufficient understanding of the inherent mechanisms of the tempo perception. Published methods only use the information of rhythm pattern, so they may meet the half/double tempo error problem. To solve(More)

We consider an interactive information retrieval task in which the user is interested in finding several to many relevant documents with minimal effort. Given an initial document ranking, user interaction with the system produces relevance feedback (RF) which the system then uses to revise the ranking. This interactive process repeats until the user(More)
QODI is an ontology-based data integration system (OBDI) comprising both ontology mapping and query reformulation methods. QODI is distinguished in that the ontology mapping algorithm dynamically determines a partial mapping specific to the reformulation of each query. The mapping algorithm decomposes a query into a set of paths, and compares the sets of(More)
In RoboCup, the problem of quickly and accurately processing visual data continues to pose a significant challenge. The Aldebaran Nao, currently used by the Standard Platform League, has two cameras for visual input, of which only one has been typically used. The integration of both cameras presents a new opportunity but also a challenge. While it is(More)
In 2008, UT Austin Villa entered a team in the first Nao competition of the Standard Platform League of the RoboCup competition. The team had previous experience in RoboCup in the Aibo leagues. Using this past experience, the team developed an entirely new codebase for the Nao. In 2009, UT Austin combined forces with Texas Tech University, to form TT-UT(More)
We propose an approach to automatically generate photo-on-photo compositions using only a consumer's own image collection, without imposing a strong theme constraint dictated by typical background art designs. Our goal is to ensure adequate foreground and background photo sizing, avoid occlusion of important background photo content, and respect simple(More)
Automatic schema matching algorithms are typically only concerned with finding attribute correspondences. However, real world data integration problems often require matchings whose arguments span all three types of elements in relational databases: relation, attribute and data value. This paper introduces the definitions and semantics of three additional(More)
This paper introduces the ontology mapping approach of a system that automatically integrates data sources into an ontology-based data integration system (OBDI). In addition to the target and source ontologies, the mapping algorithm requires a SPARQL query to determine the ontology mapping. Further, the mapping algorithm is dynamic: running each time a(More)
