Abstract: A method to analyze popularity of user defined topics by identifying correlations between grams contained in user identified anchor documents and the grams contained in raw documents includes the following steps: (a) a user input data that includes (i) user identified topics for user identified subject matter, (ii) user identified topical anchor documents, and (iii) a plurality of user identified raw documents internet source with respective source addresses; (b) the raw document sources is accessed using the source addresses to retrieve and store data in a database; (c) grams and gram document dictionaries together with gram values for each topical anchor document and raw document are identified and stored; and (d) the grams in each of the topical anchor documents against the grams in all the raw documents are analyzed to determine a relative popularity of the topical anchor documents.

Abstract: An optical fiber communication system has an optical fiber extending along a communication path between spaced stations. The stations include transmitting and receiving units, or combined transmitter and receiver units at each station. Each transmitter unit is designed to produce information signals on one or more different topics, and is associated with one light source for each topic of information assigned to that station. The light sources produce output light signals modulated by the information signals, and these light signals are coupled to the optical fiber. The light sources are of different frequencies, and each topic of information to be communicated is assigned to a predetermined light frequency, so that all light signals at a certain frequency carry only information on the one topic assigned to that frequency. Each receiver unit includes a filter for filtering out signals at one or more of the frequencies and a decoder for extracting the information from the filtered signal.
