Abstract: A contextual analysis engine systematically extracts, analyzes and organizes digital content stored in an electronic file such as a webpage. Content can be extracted using a text extraction module which is capable of separating the content which is to be analyzed from less meaningful content such as format specifications and programming scripts. The resulting unstructured corpus of plain text can then be passed to a text analytics module capable of generating a structured categorization of topics included within the content. This structured categorization can be organized based on a content topic ontology which may have been previously defined or which may be developed in real-time. The systems disclosed herein optionally include an input/output interface capable of managing workflows of the text extraction module and the text analytics module, administering a cache of previously generated results, and interfacing with other applications that leverage the disclosed contextual analysis services.

Abstract: A method for using an undo stack to explore past actions and apply new actions to previous states in a data view. The method includes detecting a change in an application data view. The application then displays an undo stack and stores the data change in the application data view to the undo stack. Upon detecting a selection of the undo stack entry for undo, the application returns the application data view to the state represented by the undo stack entry. The method further includes providing a user interface allowing a user to perform operations on undo stack entries. Responsive to the user utilizing the user interface and making selections, the application then adjusts the application data view state based on the performed actions.

Abstract: A method for constructing a context profile within a system implementing symmetrical object profiles. The method includes establishing one or more contextual boundary parameters defining a context within which transactions occur. A plurality of transactions associated with the context is filtered using the contextual boundary parameters to obtain a pool of filtered transactions. Each of the transactions is conducted between at least two objects in the system including a plurality of objects associated with the symmetrical object profiles. An array of filtered objects including objects involved in at least one filtered transaction is established. Each filtered object is defined by a current version of a corresponding object profile and is associated with a corresponding transaction. The method includes generating a context object profile associated with the context that is based on attribute values of filtered object profiles associated with the array of filtered objects.

An in-memory array holding a column of data can be maintained. One or more pages can be maintained. Each of the one or more pages can have one or more rows for storing the column of data. Random access can be provided to a subset of the one or more rows by at least loading the subset of rows from the one or more pages to the in-memory array without loading all of the rows from the one or more pages. Related apparatus, systems, techniques, and articles are also described.

Abstract: Computer-implemented systems and methods are disclosed for automatically aggregating, analyzing, and presenting probabilities associated with data items. Data items may be associated with probabilities or risks, and the data items may have various characteristics. A grouping of data items may be determined based on these characteristics, and probabilities within groups of data items may be aggregated and analyzed. Aggregated probabilities may be used to determine incremental probabilities for individual data items, to assess cumulative risk associated with a group of data items, and to analyze probabilities associated with a particular data item group. User interfaces may be generated to facilitate selection and grouping of data items, selection of risk models, and analysis of aggregate probabilities.

The method is carried out by an application recommendation node.

Abstract: A privacy-preserving multi-query parking management system and method. An image of a vehicle with respect to a specific part (e.g., license plate) can be captured when the vehicle enters via an entry point. An image signature can be computed by embedding the image into a descriptor space and the image signature can be stored in a database together with relevant metadata. An image of a vehicle with respect to the specific part can be captured when the vehicle exits via at least one exit point and an image signature can be computed. An entry-exit association with respect to the vehicle can be performed by searching for a most similar image signature in the database. Additionally, given a textual query (e.g., a license plate number), a signature can be computed by embedding the text into the same descriptor space.

Abstract: Systems and methods can identify potential entities from facts generated from web-based sources. For example, a method may include generating a source data graph for a potential entity from a text document in which the potential entity is identified. The source data graph represents the potential entity and facts about the potential entity from the text document. The method may also include clustering a plurality of source data graphs, each for a different text document, by entity name and type, wherein at least one cluster includes the potential entity. The method may also include verifying the potential entity using the cluster by corroborating at least a quantity of determinative facts about the potential entity and storing the potential entity and the facts about the potential entity, wherein each stored fact has at least one associated text document.

Abstract: Log records are accessed as part of a database operation in a database. The log records log insert, update, and delete operations in the database and include, for each row, a row position, a fragment identifier (ID), and a row ID. Thereafter, as part of the database operation, rows specified by the log records are located by: using the fragment identifier and the row position within the corresponding record of the log if the fragment with the corresponding fragment identifier is still available, otherwise, using the row identifier within the corresponding record of the log to look up the row position in an index of a corresponding row identifier column. The database operation is then finalized using the located rows. Related apparatus, systems, techniques and articles are also described.

Abstract: The present invention generally relates to a method and system for retrieving search results. More particularly, the present invention relates to a method and system for retrieving search results concurrently from multiple disparate databases, whether such databases be available through the Web, or other proprietary internal networks. In an exemplary embodiment, the system includes a user interface, a control engine, and a number of translators which are used to communicate with a number of corresponding databases. During exemplary operation, a user uses the user interface to enter search term(s) and other pertinent information relating to his/her search and specify which ones of the databases are to be searched. The search term(s) and other pertinent information are then relayed to the control engine which, in turn, forwards them to the appropriate translators which correspond to the specified databases to be searched.

Abstract: Disclosed are methods and apparatus for providing version control for a model. A database (102) is divided into three logical areas corresponding to working model area (120), full model area (122), and permanent model area (124). Data, which may be CIM formatted data, imported into the model is validated against data previously stored in the full model area (122) and version controlled based in part on timestamp data. The version controlled data may then be exported for use by network applications. Imported data may come from a power system utility while the exported data may be used for control of such a utility.

Abstract: Disclosed herein are system, method, and computer program product embodiments for performing garbage collection in a database management system with a multi-version concurrency control. An embodiment operate by qualifying a multi-version concurrency control (MVCC) block for garbage collection, where the MVCC block includes multiple cells, each cell corresponding to a row of a table that was acted on by a transaction. Determining that the MVCC block can be garbage collected based on MVCC information in the MVCC block, where the MVCC information includes information that determines whether changes made to rows in the multiple cells are visible in a database management system. Based on the determining, garbage collecting the MVCC block.
