摘要： A method is disclosed for reproducible sampling of data items of a dataset which is shared across a plurality of nodes of a parallel data processing system.In data mining of large databases, segmentation of the database is often necessary either to obtain a summary of the database or prior to an operation such as link analysis. A sample of data records are taken to create an initial segmentation model. The records of this sample and the initial model created from them can be critical to the results of the data mining process, and the initial model may not be reproducible unless the same sampling of data records is repeatable. Reproducible sampling is enabled without polling of all nodes to locate particular records. Parametric control information with a small number of control parameters is generated which describes the particular partitioning of the dataset. The parametric control information enables computing of the location of a data record. The parametric control information may be distributed to each node and enable computing of the location of data records by each node. The invention is applicable to other sampling methods.

摘要： A parallel processing system having a number of processing nodes (S1 . . . Sn) each of which is provided with a message handling kernel (13 . . . n3) and an associated procedure register (14 . . . n4), the procedure registers being loadable by loading means (4) under the control of an application (3) and the nodes being able to exchange messages over a message interface (2) and to process messages to determine the message handling procedures to be invoked by the associated node in accordance with the contents of the associated procedure register.

摘要： A method and system for generating a taxonomy for documents from tag data are provided. The method includes obtaining tag data in the form of tags on documents with tag weightings for a document and clustering the tags using the tag weightings for documents, wherein each cluster is an identified subject. The documents are associated with each identified subject and the subjects are compared to identifying relationships between subjects to build a taxonomy of subjects. A tag weighting for a document is the number of times the tag is applied to the document with a user rating of the relevance of the tag to the document. The steps are carried out automatically without user intervention.

摘要： An electrochromic display device having first and second electrodes, and a plurality of display electrodes, all immersed in a liquid electrolyte. Drive means act to first generate a potential difference between said first and second electrodes to cause a color species to be deposited on said first electrode and, thereafter, act to generate a potential difference between said first electrode and selected ones of said plurality of display electrodes to cause the color species to be transferred to the selected ones of said plurality of display electrodes. Heptyl viologen dibromide is suggested as one possible electrolyte.
