Title: Method and system to discover and recommend interesting documents

Abstract

Disclosed are several examples of systems that can read millions of news feeds per day about topics (e.g., your customers, competitors, markets, and partners), and provide a small set of the most relevant items to read to keep current with the overwhelming amount of information currently available. Topics of interest can be chosen by the user of the system for use as seeds. The seeds can be vectorized and compared with the target documents to determine their similarity. The similarities can be sorted from highest to lowest so that the most similar seed and target documents are at the top of the list. This output can be produced in XML format so that an RSS Reader can format the XML. This allows for easy Internet access to these recommendations.

  • Disclosed is a method and system for discovering documents using a computer and providing a small set of the most relevant documents to the attention of a human observer. Using the method, the computer obtains a seed document from the user and generates a seed document vector using term frequency-inverse corpus frequency weighting. A keyword index for a plurality of source documents can be compared with the weighted terms of the seed document vector. The comparison is then filtered to reduce the number of documents, which define an initial subset of the source documents. Initial subset vectors are generated andmore » compared to the seed document vector to obtain a similarity value for each comparison. Based on the similarity value, the method then recommends one or more of the source documents.« less
  • A method and apparatus for the detection of leaks in an interconnected pipeline system are disclosed. The method involves recording flow characteristics over a specific, short time period, e.g., one-half hour daily, at control stations distributed throughout the network. By arranging the control stations in this manner, subnetworks are defined and the existence of leaks therein determined in accordance with deviations in measurements which facilitate localization procedures for the leaks. The apparatus is a well for use at the control stations immovably fixed in the network and accessible from the outside.
  • This invention relates to a method of controlling the energy management of a system for catching, accumulating and transferring heat comprising a heat collector and a heat accumulator of the thermally stratified type forming part of a heat recovery circuit adapted to pass a heat transport fluid, said heat accumulator forming furthermore part of a consumer circuit adapted to pass the heat transport fluid. Experiments have now shown that excellent efficiency is obtained by using this method in which the heat capacity flux, that is to say, the mass flux multiplied by the specific heat of the heat transport fluidmore » through the consumer circuit and the mean value thereof during a selectable time interval, is determined or estimated at least by approximation and the heat capacity flux through the heat recovery circuit is adjusted so that the difference between the mean value of the heat capacity flux through the heat recovery circuit during a time interval of the same duration as said selectable time interval and said mean value of the heat capacity current through the consumer circuit is equal to a factor to be selected multiplied by the heat capacity of the heat accumulator, divided by said time interval, said factor lying between 0 and 3. Further the invention relates to a system for carrying out said method.« less
  • The invention pertains to compounds which specifically bind radionuclides, and to methods of making radionuclide complexing compounds. In one aspect, the invention includes a radionuclide delivery system comprising: a) a calix[n]arene-crown-[m]-ether compound, wherein n is an integer greater than 3, and wherein m is an integer greater than 3, the calix[n]arene-crown-[m]-ether compound comprising at least two ionizable groups; and b) an antibody attached to the calix[n]arene-crown-[m]-ether compound. In another aspect, the invention includes a method of making a radium complexing compound, comprising: a) providing a calix[n]arene compound, wherein n is an integer greater than 3, the calix[n]arene compound comprising nmore » phenolic hydroxyl groups; b) providing a crown ether precursor, the crown ether precursor comprising a pair of tosylated ends; c) reacting the pair of tosylated ends with a pair of the phenolic hydroxyl groups to convert said pair of phenolic hydroxyl groups to ether linkages, the ether linkages connecting the crown ether precursor to the calix[n]arene to form a calix[n]arene-crown-[m]-ether compound, wherein m is an integer greater than 3; d) converting remaining phenolic hydroxyl groups to esters; e) converting the esters to acids, the acids being proximate a crown-[m]-ether portion of the calix[n]arene-crown-[m]-ether compound; and f) providing a Ra.sup.2+ ion within the crown-[m]-ether portion of the calix[n]arene-crown-[m]-ether compound.« less
