摘要： Techniques are disclosed for multi-granularity hierarchical aggregate selection based on update, storage and response constraints. For example, for a temporal hierarchy of aggregation statistics associated with a plurality of database records, wherein the temporal hierarchy comprises two or more aggregation statistics levels and each level has a different temporal granularity associated therewith, a method comprises iteratively modifying the temporal hierarchy to at least one of: (a) minimize a storage usage cost while satisfying a temporal hierarchy update constraint and a query response time constraint; (b) reduce a temporal hierarchy update time and a query response time while satisfying a storage usage constraint; and (c) minimize a query response time for frequently applied queries that do not shift in time while satisfying the storage usage constraint, wherein the resulting temporal hierarchy that achieves at least one of (a), (b) and (c) is identified as an optimal temporal hierarchy.

摘要： Systems and methods for conducting attribute-based queries over a plurality of objects using bounded memory locations and minimizing costly input and output operations are provided. A plurality of attributes are associated with each object, and a plurality of data groups, one each for the identified attributes are created. The objects associated with the attributes are placed into the appropriate data groups, and the objects contained within each data group are sorted into blocks such that each block within a given attribute contains that objects having the same attribute value. Results to the query are created by loading blocks into a primary memory location in a middleware system and combining the loaded blocks to create the desire query results. Block combinations are created based upon the fit of the given block combination to the query as expressed in an aggregation function. A second dedicated memory location can also be provided to hold multiple block combinations to optimize the order in which blocks are loaded and combined. Empty block buffers and external storage devices can also be provided to further enhance the generation of query results.

摘要： Linear optimization queries, which usually arise in various decision support and resource planning applications, are queries that retrieve top N data records (where N is an integer greater than zero) which satisfy a specific optimization criterion. The optimization criterion is to either maximize or minimize a linear equation. The coefficients of the linear equation are given at query time. Methods and apparatus are disclosed for constructing, maintaining and utilizing a multidimensional indexing structure of database records to improve the execution speed of linear optimization queries. Database records with numerical attributes are organized into a number of layers and each layer represents a geometric structure called convex hull. Such linear optimization queries are processed by searching from the outer-most layer of this multi-layer indexing structure inwards. At least one record per layer will satisfy the query criterion and the number of layers needed to be searched depends on the spatial distribution of records, the query-issued linear coefficients, and N, the number of records to be returned. When N is small compared to the total size of the database, answering the query typically requires searching only a small fraction of all relevant records, resulting in a tremendous speedup as compared to linearly scanning the entire dataset.

摘要： A method, system, and computer program for enabling parametric searches on source data using text search engine. The invention is generally divided into a build-time process and a run-time process. During the build-time process, a crawler extracts data units from source data. A data translator then translates data units into keyword parametric entries that are submitted to the text search engine. During the run-time process, a query translator translates parametric search queries into keyword search entries. A metatag refiner then filters intermediate search results from the search engine based on the parametric search query.

摘要： Apparatus and methods for auctioning time and desktop space to product and service suppliers are provided. The apparatus and methods obtain bids from various product and service suppliers and determine which of the bids are the highest ranking bids. The particular product and service suppliers from which bids are obtained may be determined based on user preferences stored in a user profile, for example. Based on the ranking of the bids, commercial information from the product and/or service suppliers is presented to the user. Higher ranking bids are provided with larger display space on a user's client device display and are provided with a longer display time before cycling to the next lower ranking bid. In addition, multiple displays of commercial information may be provided at a same time with the size and duration of the displays being determined based on the ranking of the associated bid from the product/service supplier.

The method includes receiving at least one nonstationary data stream with time dependent data. Calculating, for a given instant of sub-space of time, A set of first-moment statistical values is calculated, for a given instant of sub-space of time, for the data. The first moment statistical values include a principal component for the sub-space of time. The data is perturbed with noise along the principal component in proportion to the first-moment of statistical values so that at least part of a set of second-moment statistical values for the data is perturbed by the noise only within a predetermined variance.
