 | Riloff, Ellen M. | Bootstrapping method for learning semantic lexicons using extraction pattern contexts | This paper describes a bootstrapping algorithm called Basilisk that learns high-quality semantic lexicons for multiple categories. Basilisk begins with an unannotated corpus and seed words for each semantic category, which are then bootstrapped to learn new words for each category. Basilisk hypothe... | Basilisk; Bootstrapping method; Semantic lexicons | 2002 |

 | Balasubramonian, Rajeev | Energy-efficient processor design using multiple clock domains with dynamic voltage and frequency scaling | As clock frequency increases and feature size decreases, clock distribution and wire delays present a growing challenge to the designers of singly-clocked, globally synchronous systems. We describe an alternative approach, which we call a Multiple Clock Domain (MCD) processor in which the chip is d... | Multiple clock domains; Synchronization; Microarchitecture | 2002 |

 | Riloff, Ellen M. | Exploiting strong syntactic heuristics and co-training to learn semantic lexicons | We present a bootstrapping method that uses strong syntactic heuristics to learn semantic lexicons. The three sources of information are appositives, compound nouns, and ISA clauses. We apply heuristics to these syntactic structures, embed them in a bootstrapping architecture, and combine them with... | Syntactic heuristics; Semantic lexicons; Bootstrapping method; Appositives; Compound nouns; ISA clauses; Co-training | 2002 |

 | Freire, Juliana | From XML schema to relations: a cost-based approach to XML storage | As Web applications manipulate an increasing amount of XML, there is a growing interest in storing XML data in relational databases. Due to the mismatch between the complexity of XML's tree structure and the simplicity of flat relational tables, there are many ways to store the same document in an ... | LegoDB; XML Schema | 2002 |

 | Riloff, Ellen M. | Inducing information extraction systems for new languages via cross-language projection | Information extraction (IE) systems are costly to build because they require development texts, parsing tools, and specialized dictionaries for each application domain and each natural language that needs to be processed. We present a novel method for rapidly creating IE systems for new languages by... | Information extraction; IE systems; Cross-language projection; English; French | 2002 |

 | Balasubramonian, Rajeev | Integrating adaptive on-chip storage structures for reduced dynamic power | Energy efficiency in microarchitectures has become a necessity. Significant dynamic energy savings can be realized for adaptive storage structures such as caches, issue queues, and register files by disabling unnecessary storage resources. Prior studies have analyzed individual structures and their... | Microarchitecture | 2002 |

 | Hansen, Charles D. | Semotus visum: a flexible remote visualization framework | By offering more detail and precision, large data sets can provide greater insights to researchers than small data sets. However, these data sets require greater computing resources to view and manage. Remote visualization techniques allow the use of computers that cannot be operated locally. The S... | Remote visualization; Semotus Visum | 2002 |

 | Hansen, Charles D. | Multidimensional transfer functions for interactive volume rendering | Abstract-Most direct volume renderings produced today employ one-dimensional transfer functions which assign color and opacity to the volume based solely on the single scalar quantity which comprises the data set. Though they have not received widespread attention, multidimensional transfer function... | 2002-07 | |

 | Thompson, Cynthia A. | A personalized system for conversational recommendations | Increased computing power and theWeb have made information widely accessible. In turn, this has encouraged the development of recommendation systems that help users find items of interest, such as books or restaurants.

 | Willemsen, Peter; Gooch, Amy A. | An experimental comparison of perceived egocentric distance in real, image-based, and traditional virtual environment using direct walking tasks | In virtual environments, perceived egocentric distances are often underestimated when compared to the same distance judgments in the real world.

 | Thompson, William B.; Willemsen, Peter; Gooch, Amy A.; Creem-Regehr, Sarah Hope | Does the quality of the computer graphics matter when judging distances in visually immersive environments? | In the real world, people are quite accurate judging distances to locations in the environment, at least for targets resting on the ground plane and distances out to about 20m. Distance judgments in visually immersive environments are much less accurate. Several studies have now shown that in vis... | Visually immersive environments | 2002-12-05 |

 | Tasdizen, Tolga; Whitaker, Ross T. | Geometric surface processing via normal maps | The generalization of signal and image processing to surfaces entails filtering the normals of the surface, rather than filtering the positions of points on a mesh. Using a variational framework, smooth surfaces minimize the norm of the derivative of the surface normals? i.e. total curvature. Pen... | Geometric surface processing; Surface models | 2002-01-17 |

 | Regehr, John | Inferring scheduling behavior with hourglass | Although computer programs explicitly represent data values, time values are usually implicit. This makes it difficult to analyze and debug real-time programs whose correctness depends partially on the time at which results are computed.
