  • Publication number: 20100217761
    Abstract: The present invention provides a system for enhancing the decoding performance of text indexes of an indexed collection of text documents. The posting list includes a plurality of list entries being of variable size depending on the value stored in each posting list entry. The inventive system is based on a statistical analysis of the posting list entries of the plurality of list entries. Prior to decoding, the system can select a decoding procedure being appropriate to decode the most frequent type of posting list entries or of a plurality of various posting list entries. After selecting a particular decoding procedure and executing the decoding procedure for decoding of the entire posting list, a failure check is performed. In the exceptional case that a failure has occurred, a second alternative decoding procedure is selected and executed.

  • Publication number: 20080098254
    Abstract: A method for autonomous dynamic voltage (v) and frequency (f) scaling (DVFS) of a microprocessor, wherein autonomous detection of phases of high microprocessor workload and prediction of their duration is performed (PID). The microprocessor frequency (f) will be temporarily increased (LUT) to an appropriate safe value (even beyond its nominal frequency) consistent with technological and ambient constraints in order to improve performance when the computer system comprising the microprocessor benefits most, while during phases of low microprocessor workload its frequency (f) and voltage (v) will be decreased to save energy. This technique exploits hidden performance capabilities and improves the total performance of a computer system without compromising operational stability. No additional hardware such as service processors is needed for contemporary computer systems supporting performance counters and DFVS already.

  • Publication number: 20080027918
    Abstract: The present invention relates to a method of generating a distributed text index for parallel query processing by a number of nodes. A set of node indices is generated for text indexing a set of documents, each node text index covering a subset of the documents. For each node text index, a local frequency measure for each term of the node text index is calculated on the basis of a frequency of documents containing the term in the subset of the documents of the node. A global frequency measure for each term is calculated on the basis of a frequency of documents containing the term in the set of documents. A quality measure for each node text index is calculated on the basis of the local frequency measures of the terms of the node and the global frequency measure of the terms of the node.

  • Publication number: 20060155530
    Abstract: A method for the generation of large volumes of text documents comprises the steps of collecting a set of unstructured text documents as training documents and choosing a language model (21). New documents are generated by using the language model and its parameters and by using additional words beyond the words contained in the training documents (25). A n-gram model or a probabilistic deterministic context-free grammar (PCFG) model may be used as language model. For the generation of structured documents a language model for modelling the text is combined with a probabilistic deterministic finite automata (PDFA) for modelling the structure of the documents. The combined model is used to generate new documents from the scratch or by using the results of an analysis of a set of training documents.
