Abstract: A “Music Mapper” automatically constructs a set coordinate vectors for use in inferring similarity between various pieces of music. In particular, given a music similarity graph expressed as links between various artists, albums, songs, etc., the Music Mapper applies a recursive embedding process to embed each of the graphs music entries into a multi-dimensional space. This recursive embedding process also embeds new music items added to the music similarity graph without reembedding existing entries so long a convergent embedding solution is achieved. Given this embedding, coordinate vectors are then computed for each of the embedded musical items. The similarity between any two musical items is then determined as either a function of the distance between the two corresponding vectors. In various embodiments, this similarity is then used in constructing music playlists given one or more random or user selected seed songs or in a statistical music clustering process.

Abstract: A base table is scanned with a delete marker and an insert marker. The delete marker identifies a last change committed to the base table as part of a transaction prior to execution of a statement, and the insert marker identifies a last change committed to base table as part of the transaction during execution of the statement. The results of the delete marker scan are filtered with deletions stored in a delta table, and a delete table is populated with the filtered rows. The results of the insert scan are filtered with insertions stored in the delta table, and an insert table is populated with the filtered rows.

Abstract: A comprehensive Memory-Resident Database Management System architecture and implementation is disclosed where a) all data storage in database is in memory, b) all database management functionality is in memory except backup and recovery storage based on hard disk, c) all database objects including tables, views, triggers, procedures, functions . . . are in memory, d) all data security is at memory level, e) all data indexed, sorted and searched based on the selected search algorithms are in memory, f) all logging functionality to refresh in-between transactions reside in memory. Therefore, the processing speed of database query will take advantage of speed of RAM (Random Access Memory) without sacrifice any speed losing on Hard disk I/O. Not only the whole database is running in RAM, but also all or pre-selected database table columns are default to be indexed. All internal processing of database query is based on indexed columns.

Abstract: A method, apparatus and computer instructions are disclosed for maintaining the compatibility of a multiple nodes in a distributed systems management environment with multiple configuration settings, by transforming the configuration data stored in the master repository (one possible realization is where XML documents contain the configuration data) from one version of the product to a previous version of the product. For multiple versions of the systems management environment, a transformation pipeline process (one possible realization of such a process may utilize XSLT) can be used by a “master” node to transform the configuration data multiple times for each version of the environment, until the configuration data has the format of the intended recipient “slave” node.

Abstract: Methods, systems, and articles of manufacture for propagating annotations created for data objects appearing in a variety of different application types are provided. Some embodiments present users collaborating on a project with an indication of data objects in a current document that have been annotated, or that related data objects have been annotated, in other documents. Users may then review the annotations and selectively associate the annotations with the related data object in the current document, thereby spreading the tacit knowledge reflected in the annotation about related data objects across many documents in an enterprise network. Further, an annotation management system may maintain a thesaurus of related terms and corresponding annotation points to find annotations for data objects that exist in other documents without having to inspect the data object(s) associated with each existing annotation.

Abstract: A method and computer system for web-interface mediated software testing is disclosed. The computer system includes an application server that provides a web interface for organizing and managing test cases by organizing test cases by the Requirements and Sub-Requirements of a Project. Users can schedule test cases to run on one or more host machines that have loaded thereon a copy of the software being tested, or some part thereof, and an automation tool.

Techniques are also provided to allow users to store data for a number of custom object types without adding any new tables to the repository. According to one technique, information identifying the attributes of a custom object type is stored in a catalog table, and the data for the attributes is stored in tables corresponding to the attributes' data types. Techniques are further provided that allow retrieval of data for custom object types and custom attributes stored in the repository tables.

Abstract: Returning rows having column values masked is disclosed. In response to receiving a database command, a modified database command is created that specifies whether to mask a value by returning a mask of the value instead of the value. In an embodiment, the condition expression is included in a policy function that is referenced by a policy. In an embodiment, the policy determines how the condition expressions are used. The condition expression may be used to determine which column values to mask. The condition expression may also be used to filter which rows are returned.

Abstract: A method and system for providing customized filters to restrict datasets retrieved from a database are described. In one embodiment, the method includes receiving a template data access query from a first user, identifying multiple data elements from database tables that are to be accessed according to the template data access query, creating a set of preliminary filters based on the multiple data elements, presenting to a second user the layout of a data presentation and some or all of the preliminary filters, and creating final filters using filter parameters specified by the second user for the preliminary filters. The final filters restrict the content to be retrieved from a database for the data presentation. The method further includes building for the second user the data presentation with the content that is retrieved from the database using the final filters.

Abstract: A multi-version database system controls visibility of data during transaction processing. A transaction includes a transaction identifier that identifies the transaction and an invisibility list of transactions whose effects are invisible to the transaction. Changes made by other transactions are visible to the transaction based on the isolation level of the transaction. Records are visible to a transaction based on a creator identifier stored in the record that identifies the transaction that created the record.

Abstract: A computer system and method is disclosed that transforms data for use in other applications. Several client workstations and servers are coupled together over a network. A client computer contains a user interface for performing the mapping and transformation. Data elements are mapped from a data source to a multi-dimensional cube. The multi-dimensional cube is transformed into a test recordset to determine if the data elements are mapped correctly. The mapping information is saved to a template. A server includes business logic for using the saved template to create a final recordset from the data source using the template. The server sends at least part of the recordset to a browser user interface on a client computer for display.

Abstract: A method and system of subsetting a group of server systems configures a server system with a group name and a group port, and with at least one subset name and subset port. The server system, when activated, reads its configuration and registers with a system routing entity as being part of the group name and the group port, and as being part of the subset name and the subset port. In this manner, server systems can be targeted via its subset name and subset port, while also accessible via the common name and port for the group. If the group includes a workload balancer, the server system also registers with the workload balancer using the group name and the subset name, such that workload balancing is provided for the subset.

Abstract: Outlier detection methods and apparatus have light computational resources requirement, especially on the storage requirement, and yet achieve a state-of-the-art predictive performance. The outlier detection problem is first reduced to that of a classification learning problem, and then selective sampling based on uncertainty of prediction is applied to further reduce the amount of data required for data analysis, resulting in enhanced predictive performance. The reduction to classification essentially consists in using the unlabeled normal data as positive examples, and randomly generated synthesized examples as negative examples. Application of selective sampling makes use of an underlying, arbitrary classification learning algorithm, the data labeled by the above procedure, and proceeds iteratively.

Abstract: Desired transformations such as compression, encryption and/or encoding are applied to data such that the number of duplicate chunks in the transformed data is increased and the chunks are predominantly of a predetermined size. Additionally, the unique and duplicate chunks of transformed data are identified. A variable-sized window is passed over the set of data to generate a working chunk of transformed data that is of the predetermined size. When the working chunk is a duplicate chunk of data, a next group of untransformed data is selected from the set of data, transformed and then evaluated. When the working chunk is not a duplicate chunk of data, a next group of data is selected by sliding the window over the set of data to generate another working chunk that is evaluated.

Abstract: Indexed documents are arranged in the index according to a static ranking and partitioned according to static ranking. Index queries reference the first partition and move to a subsequent partition when a static rank for the subsequent partition is higher than a weighted portion of the target score added to a weighted portion of a dynamic rank corresponding to the relevance of the results set generated thus far. By changing the weight of the target score and dynamic ranks in the subsequent partition score, searches can be stopped when no more relevant results will be found in the next partition.
