Back, Godmar V. | Java operating systems: design and implementation | Language-based extensible systems such as Java use type safety to provide memory safety in a single address space. Memory safety alone, however, is not sufficient to protect different applications from each other. such systems must support a process model that enables the control and management of c... | Java operating systems; Language-based systems | 1998 |

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.

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. Instead of a large quantity ... | Bootstrapping; Text learning algorithms; Seed information | 1999 |

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. Image processing algorithms tend to have poor memory locality because they access their data in a non-se... | Processor speeds; Memory system support; Memory speeds | 1999 |

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.

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.

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 |

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.

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 |
