摘要： Method and system to utilize the set of navigation paths of web pages as the contextual information for subject relevant web page filtering with high accuracy are provided. The method comprises the steps of: obtaining all web pages in one or more web pages collections; collecting information of the links among the obtained web pages; extracting, based on the collected links, a set of navigation paths of each of the obtained web pages; and filtering the obtained web pages based on the extracted set of navigation paths to obtain desired web pages. In some embodiments, the extraction of the navigation paths is preferably performed on the navigation links of the web pages. Therefore, the method also comprises the process for deleting non-navigation links from all the links of the web pages. Compared with the prior art, the present invention can utilize the contextual information of the web pages for web page filtering in a more sufficient way, thereby improving the accuracy and objectivity of the web page filtering.

摘要： Aspects of the present invention include apparatus and methods for transmitting and receiving signals in communication systems. A multicarrier generator generates a multicarrier signal. An optical demultiplexer separates the multicarrier signal into separate multicarrier signals. At least one QPSK modulator modulates signals from the separate multicarrier signals. An optical multiplexer combines the QPSK modulated signals into a multiplexed signal. The multiplexed signal is then transmitted.
