Freire, Juliana | Designing information-preserving mapping schemes for XML | An XML-to-relational mapping scheme consists of a procedure for shredding XML documents into relational databases, a procedure for publishing databases back as documents, and a set of constraints the databases must satisfy. In previous work, we discussed two notions of information preservation for m... | Losslessness; Validation; Mapping scheme; Edge++; LILO; Lossless Inlining; Lossless Outlining; XML Schema | 2005 |

Riloff, Ellen M. | Exploiting subjectivity classification to improve information extraction | Information extraction (IE) systems are prone to false hits for a variety of reasons and we observed that many of these false hits occur in sentences that contain subjective language (e.g., opinions, emotions, and sentiments). Motivated by these observations, we explore the idea of using subjecti... | Subjectivity classification; Information extraction; Subjectivity analysis; MUC-4 | 2005 |

Brunvand, Erik L. | HDL modeling for analysis and optimization of asynchronous controllers | We propose a simulation-based technique for analysis and optimization of extended burst-mode (XBM) asynchronous controllers. In asynchronous controllers of this sort, timing information on control signals is significant both for performance enhancement and timing validation. Timing information, ... | | 2005 |

Riloff, Ellen M. | Identifying sources of opinions with conditional random fields and extraction patterns | Recent systems have been developed for sentiment classification, opinion recognition, and opinion analysis (e.g., detecting polarity and strength). We pursue another aspect of opinion analysis: identifying the sources of opinions, emotions, and sentiments. We view this problem as an information ext... | Sentiment classification; Opinion recognition; Opinion analysis; Conditional random fields; AutoSlog; Sources of opinions | 2005 |

Freire, Juliana | IMAX: incremental maintenance of schema-based XML statistics | Current approaches for estimating the cardinality of XML queries are applicable to a static scenario wherein the underlying XML data does not change subsequent to the collection of statistics on the repository. However, in practice, many XML-based applications are dynamic and involve frequent u... | IMAX; Incremental Maintenance of XML statistics; StatiX; Datasets; Statistics | 2005 |

Parker, Steven G.; Hansen, Charles D. | Interactive volume rendering of large datasets using the silicon graphics Onyx4 visualization system | Many recent approaches to interactive volume rendering have focused on leveraging the power of commodity graphics hardware. Though currently limited to relatively small datasets, these approaches have been overwhelmingly successful. As the size of volumetric datasets continues to grow at a rapid pa... | Volume visualization; Onyx4; Interactive volume rendering; Parallel volume rendering; Large datasets; Visualization systems | 2005 |

Balasubramonian, Rajeev | Microarchitectural wire management for performance and power in partitioned architectures | Future high-performance billion-transistor processors are likely to employ partitioned architectures to achieve high clock speeds, high parallelism, low design complexity, and low power. In such architectures, inter-partition communication over global wires has a significant impact on overall proc... | Microarchitecture; Partitioned architectures; Heterogeneous interconnects; Cache access | 2005 |

Riloff, Ellen M. | OpinionFinder: a system for subjectivity analysis | OpinionFinder is a system that performs subjectivity analysis, automatically identifying when opinions, sentiments, speculations and other private states are present in text. Specifically, OpinionFinder aims to identify subjective sentences and to mark various aspects of the subjectivity in the... | OpinionFinder; Subjectivity analysis | 2005 |

Balasubramonian, Rajeev | Power-efficient approaches to reliability | Radiation-induced soft errors (transient faults) in computer systems have increased significantly over the last few years and are expected to increase even more as we move towards smaller transistor sizes and lower supply voltages. Fault detection and recovery can be achieved through redundancy. St... | Radiation-induced; Soft errors; Transient faults; Redundant thread; Trailing thread; Power consumption | 2005 |

Freire, Juliana | Searching for hidden-web databases | Recently, there has been increased interest in the retrieval and integration of hidden-Web data with a view to leverage high-quality information available in online databases. Although previous works have addressed many aspects of the actual integration, including matching form schemata and automat... | Hidden-web databases; Web documents; Large scale information integration; Focused crawler; Form crawler | 2005 |

Brunvand, Erik L. | Self-timed circuits using DCVSL semi-bundled delay wrappers | We present a technique for generating robust self-timed completion signals for general dynamic datapath circuits. The wrapper circuit is based on our previous domino semi-bundled delay (SBD) circuits, but uses DCVSL circuits in the wrapper for higher performance. We describe the basic SBD-DCVSL... | | 2005 |

Hansen, Charles D.; Tasdizen, Tolga | Statistically quantitative volume visualization | Visualization users are increasingly in need of techniques for assessing quantitative uncertainty and error in the images produced. Statistical segmentation algorithms compute these quantitative results, yet volume rendering tools typically produce only qualitative imagery via transfer function-base... | Volume visualization; Uncertainty; Classification; Risk analysis | 2005 |

Freire, Juliana; Silva, Claudio T. | VisTrails: enabling interactive multiple-view visualizations | VisTrails is a new system that enables interactive multiple-view visualizations by simplifying the creation and maintenance of visualization pipelines, and by optimizing their execution. It provides a general infrastructure that can be combined with existing visualization systems and libraries.

Balasubramonian, Rajeev | Wire management for coherence traffic in chip multiprocessors | Improvements in semiconductor technology have made it possible to include multiple processor cores on a single die. Chip Multi-Processors (CMP) are an attractive choice for future billion transistor architectures due to their low design complexity, high clock frequency, and high throughput.
