摘要： A system and method for information searching comprising determination of, in fine granularity, a Community of Interest (COI), further data mining in search results, using at least one of COI and expert preferences to identify important knowledge, formulation and manipulation of results, and summarization of search results into a document like entity with dynamic attributes described. More particularly, the invention relates to a system and method for providing interactive dialogue and iterative search functions to find information on a large network of servers such as the world wide web.

摘要： The classification of a signal on a telephone line can be based on its short term average energy level; nonspeech (data or signalling) as high level; speech as medium level, and noise as low level. A common use for speech detectors occurs with a time assignment speech interpolation (TASI) system. A speech detector extends a trunk activity signal (TAS) for indicating whether energy or noise is detected on a trunk. Responsive to the TAS signal, a processor processes a signal on the trunk. On occasion, it may be desirable to process different energy signals according to different methodologies. For example, during overload, a TASI system may truncate bits of a speech signal and not truncate bits of a nonspeech signal. For classifying energy signals as between speech signals and nonspeech signals, the instant classifier includes an arrangement for extracting at least one feature, or property, such as the short term power of the signal to be classified. Responsive to the extracted property, an estimator provides a coarse estimate as to whether the signal to be classified is a speech signal or a nonspeech signal. Responsive to the estimate, a six-state, sequency machine provides a fine, classifying signal for classifying the energy signal.
摘要翻译：电话线上的信号分类可以基于其短期平均能量水平; 非数据（数据或信令）为高级别; 语音为中等水平，噪音低等级。语音检测器的常见用法是用时间分配语音插值（TASI）系统进行。语音检测器扩展用于指示是否在中继线上检测到能量或噪声的中继线活动信号（TAS）。响应于TAS信号，处理器处理中继线上的信号。有时，可能希望根据不同的方法处理不同的能量信号。例如，在过载期间，TASI系统可以截断语音信号的比特，而不截断非同步信号的比特。为了将能量信号分类为语音信号和非同步信号之间的瞬时分类器，该分类器包括用于提取至少一个特征或属性（诸如要分类的信号的短期功率）的属性的装置。响应于所提取的属性，估计器提供关于被分类的信号是语音信号还是非同步信号的粗略估计。响应于估计，六态时序机提供了一种精细的分类信号，用于分类能量信号。
