Abstract: A system and method for migrating file systems is provided. A file system migration operation copies a plurality of files from a first file system to a second file system. A request to access one of the files being migrated during the file system migration operation results in the creation of a pseudo vnode for the file being requested in the second file system. The pseudo vnode is created prior to creating a vnode for the file in the second file system. In addition, the pseudo vnode is associated with a vnode of the file at the first file system. Information identifying the pseudo vnode is then returned to the application.

Abstract: Techniques are described for managing aggregation of data in a distributed manner, such as for a particular client based on specified configuration information. The described techniques may include storing aggregated data values for an OLAP cube or other data structure in a distributed manner, such as in some situations in a distributed hash table. The aggregated data values to be stored may be generated in various manners, such as by performing multi-stage data manipulation operations—for example, a map-reduce architecture may be used, with a first stage involving the use of one or more specified map functions to be performed, and with at least a second stage involving the use of one or more specified reduce functions to be performed.

Abstract: The distributed computing backup and recovery (DCBR) system and method provide backup and recovery for distributed computing models (e.g., NoSQL). The DCBR system extends the protections from server node-level failure and introduces persistence in time so that the evolving data set may be stored and recovered to a past point in time. The DCBR system, instead of performing backup and recovery for an entire dataset, may be configured to apply to a subset of data. Instead of keeping or recovering snapshots of the entire dataset which requires the entire cluster, the DCBR system identifies the particular nodes and/or archive files where the dataset resides so that backup or recovery may be done with a much smaller number of nodes.

Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for storing data according to permissions. In general, one aspect of the subject matter described in this specification can be embodied in methods that include the actions of identifying a version of a data item to be stored; determining permissions associated with the version of the data item; and storing the version of the data item at a storage location that is based on the determined permissions.

Abstract: In a method, system, and computer-readable medium having instructions for semantic matching, a configuration for one or more ontologies is determined with an ontology that has one or more concepts and a representation for the one or more concepts, and the configuration has an assignment of concepts to positions and one or more relationships between concepts in accordance with the representation. The configuration is optimized in accordance with one or more constraints, and a constraint has a relationship defined in a representation for an ontology and a judgment on a similarity of a plurality of concepts from the one or more ontologies, and an estimate is calculated for a similarity between a first concept and a second concept using the configuration.

Abstract: The association of semantic labels with content may be facilitated. In particular, the content in the sentences, labels, headers, text, and/or other context that surround a fact may provide information descriptive for a semantic label that has been applied to the sentence and/or fact. By analyzing some of these implicit semantic associations between semantic labels and facts (numeric or otherwise), suggestions for semantic labels may be made for previously labeled or unlabeled facts. The labels that are suggested may include suggestions for concepts, members, and other structured constructs.

Abstract: A method is provided to evaluate user interaction with a computer user interface (UI) comprising: receiving a property definition that identifies at least one relationship among prescribed string patterns that correspond to one or more UI events; receiving a log file in a computer readable storage device that includes a plurality of respective chunks of information; determining whether the respective chunks of information within the log file includes a respective string pattern that matches at least one of the prescribed string patterns; configuring a processor to produce an indication of whether the property is satisfied based upon the string pattern matching determinations.

Abstract: Systems and methods for verifying membership in one or more sets that are subsets of a global set are provided. The method compromises representing members of the global set by mapping each member to a distinct Boolean variable of length d, wherein 2d is not less than the number of members in the global set; representing each of the given subsets of the global set by a Boolean expression which evaluates to a first value for any of the assignments to the Boolean variables which represent members of the subset, and which evaluates to a second value for any of the assignments to the Boolean variables which represent members of the global set that are not members of the subset.

Abstract: Scaling Asynchronous reclamation of free space in de-duplicate multi-controller storage systems is disclosed. In one example, a set of de-duplicated data segments/blocks organized in a hierarchical data structure is received, the set of de-duplicated data segments/blocks are allocated across a plurality of controllers of the file system, where each de-duplicated data segment is restricted to be co-allocated to the same controller as the reference(s) referencing the de-duplicated data segment/block in the hierarchical data structure. In various embodiments, the file system is traversed, each controller of the file system updates its own local live vector and reclaim storage space that are not marked as alive.

In one embodiment, the software searches a web page for delimiters such as quotes that are in proximity to a link to another web page. The software stores any comments in proximity to the quoted content for use in a comment display system where it may be displayed as comment marginalia.

Abstract: A method and an apparatus for extrapolating diagnostic data relating to one pupil diameter to another pupil diameter. Embodiments according to the invention are more particularly directed to extrapolating wavefront aberration data, for example, in the form of Zernike polynomial data, obtained from a smaller pupil diameter, d1, to a larger pupil diameter, d2. Data relating to the first pupil diameter d1 may be obtained in a diagnostic procedure. In the extrapolation, a conversion matrix M is utilized. The conversion matrix M can be generated from a static matrix and a dynamic matrix, the latter taking the pupil diameter d1 into consideration. Data relating the first pupil diameter d1 and wavefront aberration data can be ordered via a permutation matrix P. If necessary, Extrapolated data can be re-ordered via a transposed permutation matrix PT.

Abstract: Techniques are described for managing aggregation of data in a distributed manner, such as for a particular client based on specified configuration information. The described techniques may include receiving information about multi-stage data manipulation operations that are to be performed as part of the data aggregation, with each stage able to be performed in a distributed manner using multiple computing nodes—for example, a map-reduce architecture may be used, with a first stage involving the use of one or more specified map functions to be performed, and with at least a second stage involving the use of one or more specified reduce functions to be performed. In some situations, a particular set of input data may be used to generate the data for a multi-dimensional OLAP (“online analytical processing”) cube, such as for input data corresponding to a large quantity of transactions of one or more types.

Abstract: Systems and methods are provided that perform data validation in real time. By uploading the source data from spreadsheets or entering the data directly into an application, the required validations can be run and reported in real time. Users can then either extract the data back into spreadsheets for manipulation, and then re-upload it, or correct the data directly within the application. Once the data set has passed all validations, it is then passed to the technical team for upload into the transactional system.

Abstract: Techniques are disclosed for generating data provenance associated with a computing system. For example, a method comprises the following steps. Information associated with the execution of a given process in a given computing environment in accordance with a given process data set is captured. A provenance data set is generated based on the captured information. The generated provenance data set comprises one or more states associated with one or more execution components of the given computing environment that existed during the execution of the given process. At least a portion of the generated provenance data set may be utilized to revert the computing environment back to the one or more states associated with the one or more execution components of the given computing environment that existed during the execution of the given process.

Abstract: A documentation inventory manager which assigns a protection key to each piece of documentation that is received. More specifically, when providing information to a receiving company, a client provides their files to a common FTP server. As a support team of the receiving company accesses the files and stores some or all of the files to a local storage system, the files are modified to include an imbedded header record. In certain embodiments, the imbedded header record includes information regarding an original file name sent by the client, a key value that is assigned to that version of the downloaded file, permissions such as whether the file can be copied, and the inventory manager location. Each time a version of the file is downloaded to a different location within the receiving company, that file name, location, and new unique key is updated in the documentation inventory manager.

Abstract: A duplicate file detection device 100 has a storage unit 101, a calculation unit 102, and a detection unit 103. The storage unit 101 stores calculation information that defines data used in the calculation of the hash values of files in association with the extensions of the files. The calculation unit 102 acquires the calculation information associated with the extension of each file to be examined from the storage unit 101 and uses the acquired calculation information to calculate the hash value of each file to be examined. The detection unit 103 detects duplicated files by comparing the hash values of the files to be examined that are calculated by the calculation unit 102.

Abstract: Disclosed is a database management method which generates an execution plan with respect to a factorized character string generated by factoring an execution value list of a query and stores the factorized character string and an execution plan identifier with respect to the factorized character string, matching each other.

Abstract: An action alignment system for event planning and execution searches out web sites relating to event planning and, based on web site content, constructs a database of various tasks that might be desired for different events (tasks can also be manually added to the database). The tasks have associated tags which allow a task search engine to match a user query representing a proposed event to potential tasks. This list of potential tasks is presented to the user who may then select the tasks as desired to customize the event plan. Vendors can provide pre-packaged deals for the tasks, and this information can be included with the task database, selected by the user, and added to the event plan. A scheduler and alert engine then inserts appropriate entries into the user's calendar, and sends timely alerts to the user which include links that simplify event management.
