Abstract: One or more classification algorithms are applied to at least one natural language document in order to extract both attributes and values of a given product. Supervised classification algorithms, semi-supervised classification algorithms, unsupervised classification algorithms or combinations of such classification algorithms may be employed for this purpose. The at least one natural language document may be obtained via a public communication network. Two or more attributes (or two or more values) thus identified may be merged to form one or more attribute phrases or value phrases. Once attributes and values have been extracted in this manner, association or linking operations may be performed to establish attribute-value pairs that are descriptive of the product. In a presently preferred embodiment, an (unsupervised) algorithm is used to generate seed attributes and values which can then support a supervised or semi-supervised classification algorithm.

Abstract: A content provider broadcasts content to subscribers through a content distribution system. The content distribution system operator can capture broadcast content in accordance with policies established by the content provider and make the content available subsequent to the original broadcast in accordance with applicable business policies. Business policies are created by the content provider by modifying template information models which have associated rules. The content distributor stores the business policies and evaluates rules indicated by the business policies against attributes of a content asset to determine availability of the content asset.

Abstract: A method of estimating a channel response of a channel is provided that includes transforming a frequency domain signal received via the channel into a time domain signal and searching the time domain signal for a location of minimum energy. The method also includes padding the time domain signal with zeroes at the location of minimum energy and transforming the padded time domain signal to a second frequency domain signal. The second frequency domain signal is used as an estimated channel response for the channel.

Abstract: A Digital Radio Mondiale (DRM) receiver and demodulation method includes an analog and digital separation filter for filtering and separating a DRM-encoded signal and a non DRM-encoded signal from a composite RF signal received at the receiver. The DRM receiver includes a programmable downsampler and a programmable N-point Fast Fourier Transform (FFT) to recover and demodulate the OFDM symbols in a received DRM-encoded RF signal. The received signal is digitally sampled at a rate operably integer downsampled to achieve a number N samples in the useful portion of the OFDM symbol for input to an N-point FFT, where N equal to a power of two. The downsampling rate and size (N-points) of the FFT depend on the DRM encoding and transmission parameters, notably the robustness mode and spectrum occupancy. The structure and operation of the receiver in this manner simplifies the design and reduces the required filter order of the analog and digital separation filter.

Abstract translation: 数字无线电广播（DRM）接收机和解调方法包括模拟和数字分离滤波器，用于从在接收机处接收的复合RF信号过滤和分离DRM编码信号和非DRM编码信号。 DRM接收机包括可编程下行采样器和可编程N点快速傅里叶变换（FFT），以在接收的DRM编码RF信号中恢复和解调OFDM符号。 接收到的信号以可操作的整数下采样的速率进行数字采样，以在OFDM符号的有用部分中实现N个采样，以输入到N点FFT，其中N等于2的幂。 FFT的下采样率和大小（N点）取决于DRM编码和传输参数，特别是鲁棒性模式和频谱占用。 以这种方式，接收机的结构和操作简化了设计，并减少了模拟和数字分离滤波器所需的滤波器顺序。
