Breaderson, Dean J. | The I3Stick: an inexpensive, immersive, interaction device | Virtual environments require interaction devices that are intuitive and ergonomic, yet capable of many input parameters. Many devices satisfying these requirements can be expensive, difficult to manipulate, and often require the integration of large software libraries with existing applications. We ... | Virtual environments; I3Stick; Interaction devices | 1999 |

Riloff, Ellen M. | Bootstrapping for text learning tasks | When applying text learning algorithms to complex tasks, it is tedious and expensive to hand-label the large amounts of training data necessary for good performance. This paper presents bootstrapping as an alternative approach to learning from large sets of labeled data.

Zhang, Lixin; Carter, John | Memory system support for image processing | Processor speeds are increasing rapidly, but memory speeds are not keeping pace. Image processing is an important application domain that is particularly impacted by this growing performance gap.

Weinstein, David | Lead field basis for FEM source localization | In recent years, significant progress has been made in the area of EEG/MEG source imaging. source imaging on simple spherical models has become increasingly efficient, with consistently reported accuracy of within 5mm. In contrast, source localization on realistic head models remains slow, with sub-... | FEM source localization; Source imaging; EEG; MEG | 1999 |

Freire, Juliana | Personalizing the web using site descriptions | The information overload on the Web has created a great need for efficient filtering mechanisms. Many sites (e.g., CNN and Quicken) address this problem by allowing a user to create personalized pages that contain only information that is of interest to the user. We propose a new approach for p... | XPointer; Data extraction; Site descriptions; Personalized web pages | 1999 |

Wright, Kristin | Using reliable multicast for caching and collaboration within the world wide web | The World Wide Web has become an important medium for information dissemination. One model for synchronized information dissemination within the Web is webcasting in which data are simultaneously distributed to multiple destinations. The Web's traditional unicast client/server communication model su... | caching; collaboration | 1999 |

Weinstein, David | Stream bundles - cohesive advection through flow fields | Streamline advection has proven an effective method for visualizing vector flow field data. Traditional streamlines do not, however, provide for investigating the coarsergrained features of complex datasets, such as the white matter tracts in the brain or the thermal conveyor belts in the ocean. In ... | Stream bundles; advection; Streamline advection; vector flow field data | 1999 |

Riloff, Ellen M. | Information extraction as a stepping stone toward story understanding | Historically story understanding systems have depended on a great deal of handcrafted knowledge. Natural language understanding systems that use conceptual knowledge structures (Schank and Abelson 1977; Cullingford 1978; Wilensky 1978; Carbonell 1979; Lehnert 1981; Kolodner 1983) typically rely on ... | Information extraction; Story understanding | 1999 |

Brunvand, Erik L. | Peephole optimization of asynchronous macromodule networks | Abstract- Most high-level synthesis tools for asynchronous circuits take descriptions in concurrent hardware description languages and generate networks of macromodules or handshake components. In this paper, we propose a peephole optimizer for these networks. Our peephole optimizer first deduces an... | | 1999 |

Zhang, Lixin | Reference manual of impulse system calls | This document describes the Im pulse system calls. The Impulse system calls allow user applications to use remapping functionality provided by the Impulse Adaptive Memory System to remap their data structures. Impulse supports several remapping algorithms. User applications choose the desired remapp... | Impulse system calls; Remapping functionality; Impulse Adaptive Memory System; Remapping algorithms | 1999 |

Carter, John B. | Using khazana to support distributed application development | One of the most important services required by most distributed applications is some form of shared data management, e.g., a directory service manages shared directory entries while groupware manages shared documents.

Johnson, Christopher R.; Parker, Steven G.; Hansen, Charles D. | Interactive simulation and visualization | Most of us perform data analysis and visualization only after everything else is finished, which often means that we don't discover errors invalidating the results of our simulation until postprocessing. A better approach would be to improve the integration of simulation and visualization into the... | Computational steering; Interactive simulation; Isosurfaces | 1999 |

Riloff, Ellen M. | Corpus-based identification of non-anaphoric noun phrases | Coreference resolution involves finding antecedents for anaphoric discourse entities, such as definite noun phrases. But many definite noun phrases are not anaphoric because their meaning can be understood from general world knowledge (e.g., "the White House" or "the news media"). We have develope... | Corpus-based identification; Non-anaphoric noun phrases; Coreference resolution; MUC-4; Discourse entity; DE | 1999 |
