Methods and systems for extracting and analyzing user-generated content (UGC) in order to provide opinion-bearing information concerning different categories of a product. Harvested Web pages are examined for keywords to identify categories to which they pertain. Opinion-bearing information regarding those categories is then extracted and analyzed to determine its orientation and, optionally, its strength. The resulting sentiment determinations can be aggregated across multiple product reviews and the like to develop a sentiment summary, which can be reported and used as the basis for advertising, marketing and purchasing decisions, among others.

A system, computer readable storage medium storing instructions, and computer-implemented method for determining sentiment expressed in documents is disclosed. A document is received from a plurality of documents. A sentence in the document that includes at least one sentiment signature within a predetermined distance of at least one keyword from a list of keywords is identified, wherein the list of keywords is extracted from the plurality of documents and is filtered using a phase transition formula, and wherein the at least one sentiment signature corresponds to an expression of at least one sentiment in the sentence. At least one category corresponding to the at least one keyword of the sentence is determined, wherein the at least one category is included in a list of categories that is generated using the list of keywords. At least one sentiment corresponding to the at least one category is determined based on the at least one sentiment signature.

A process of forming an integral hydrophilic membrane from a porous hydrophobic membrane includes exposing a porous hydrophobic polymer membrane to a plasma, wherein the plasma contains reactive carbon dioxide species configured to covalently bond carboxylic functional groups to a surface of the polymer membrane and form the integral hydrophilic membrane.
摘要:
End-to-end packet losses of one or more traffic streams transmitted across a congested network may be reduced by modulating the bandwidths of the corresponding traffic streams applied to node(s) of the network from one or more control points along the network topology. This reduction in packet loss results in a reduction in fluctuations or variability of the controlled traffic streams, an increase in bandwidth utilization and a reduction in times to transmit files. The control points can be either upstream or downstream of one or more congestion points along the network. The modulation of the bandwidths are governed by a nonlinear differential equation that involves feedback of the throughput and buffer occupancy level. The control terms involve a relaxation time, coupling constant, control constant and nonlinear feedback constants.

The present invention provides a system and method for characterizing cardiac fibrillation using wavelet transforms. By characterizing the seriousness of a fibrillation episode, a defibrillation shock may be delivered to the heart with less excess energy than conventional ICDs. A wavelet transform is performed on a digitized ECG using a second derivative weight function and the results are analyzed for missing "peaks" in the data. The more serious the fibrillation, the more peaks will be missing from the data. This information may then used to modify the voltage of the defibrillation shocks as a function of the seriousness of the fibrillation.
摘要:
A system and method for detecting ventricular fibrillation based on chaos theory. A Poincare plot of the amplitude of the ECG signal is generated and used to detect the presence of fibrillation. The plot is monitored for the data points drifting off the plot axes. Upon detecting such drift, the presence of ventricular fibrillation is confirmed. The system and method may be used as a primary detection scheme or as a backup system to reconfirm fibrillation detection using conventional techniques.
