Abstract: A Technology Program Management Model (TPMM) for management of technology development. The TPMM is an activities-based model that is subdivided along technology readiness level (TRL) boundaries into phases of technology development that logically progress from concept to operational capability and readiness for transition to the customer/end user. The TPMM provides a standardized approach to technology development that incorporates systems engineering and programmatic principles and practices with transition management in a stage-gated process for TRL-based maturity assessment. The TPMM includes a relational database that relates the activities to one another, to entry and exit criteria for each phase, and to documentation that demonstrates that the activity meets the requirements of each phase.

Abstract: There is disclosed a system and method for executing multiple distinct aggregate queries. In an embodiment, the method comprises: providing at least one Counting Bloom Filter for each distinct column of an input data stream; reviewing count values in the at least one Counting Bloom Filter for the existence of duplicates in each distinct column; and if necessary, using a distinct hash operator to remove duplicates from each distinct column of the input data stream, thereby removing the need for replicating the input data stream and minimizing distinct hash operator processing. Also, the use of Counting Bloom Filters for monitoring data streams allow an early duplicate removal of the input stream of data, resulting in savings in computation time and memory resources.

Abstract: A community search system may utilize the results of previous queries from community members and user feedback associated with those results to provide results for subsequent, similar queries from within the same community. Thus, by modifying and combining query results based, in part, on user feedback regarding previous results for similar queries, the trial and error of the many may improve the results for an individual. Users may be grouped into communities whose members are associated by common interests or characteristics. Feedback from one community member may be used to modify the query results for other community members. By analyzing user feedback with the community regarding query results, negative, incorrect or unnecessary results may be omitted or removed from subsequent results for similar queries.

Abstract: Systems and methods for injecting noise into secure function evaluation to protect the privacy of the participants and for computing a collective noisy result by combining results and noise generated based on input from the participants. When implemented using distributed computing devices, each device may have access to a subset of data. A query may be distributed to the devices, and each device applies the query to its own subset of data to obtain a subset result. Each device then divides its subset result into one or more shares, and the shares are combined to form a collective result. The devices may also generate random bits. The random bits may be combined and used to generate noise. The collective result can be combined with the noise to obtain a collective noisy result.

Abstract: There is disclosed methods, systems and computer program products for purging stored data in a repository. Users attach relative importance to all data samples across all timeseries in a repository. The importance attached to a data sample is the ‘utility value’ of the data sample. An algorithm uses the utility of data samples and allocates the storage space of the repository in such a way that the total loss of information due to purging is minimized while preserving samples with a high utility value.

The computer systems are collectively programmed to model the workflow activities worklets distinct from assistlets to recognize work people perform and to suitably represent such work, generate queries through a meta-querying template that utilize the modeled worklets received from a first processing unit, retrieve information relevant to the work task in response to the queries from a plurality of data sources, and aggregate the retrieved information for presentation to the user.

Abstract: An object tracking module establishes relationships between different types of data objects associated with application programs while a particular activity occurs. Contextual information associated with the data objects and the activity is collected to establish the relationship. The contextual information may include data objects that are accessed or created while the activity is in progress, or any other information associated with the activity. When an event related to the activity occurs, the object tracking module locates data relevant to the event based on the established relationships. The relevant data is presented in the same information space where the event occurs. A user may easily access the relevant information without manually searching for the data. The object tracking module may determine the degree of relevance between the data objects and the event such that only the most relevant objects are displayed.

Abstract: A repository contains objects including facts about entities. Some objects might be associated with the same entity. An object merge engine identifies a set of merge candidate objects. A grouping module groups the merge candidate objects based on the values of facts included in the objects. An object comparison module compares pairs of objects in each group to identify evidence for and/or against merging the pair. Evidence for merging the pair exists if, e.g., the objects have a type in common or share an uncommon fact. Evidence against merging the pair exists if, e.g., the objects have differing singleton attributes. A graph generation module generates graphs describing the evidence for and/or against merging the pair. A merging module analyzes the graphs and merges objects associated with the same entity. The merged objects are stored in the repository.

Abstract: A method and an apparatus for processing a document of a tagged internal structure made up of a plurality of elements. A plurality of documents received by a receiving unit are stored in a RAM of a storage unit provided in a main body portion of the apparatus. The characteristic information representing the characteristics of a document is extracted in accordance with the sequence of operations recorded on a ROM under control by controller. Each document is classified into classification items making up a classification model, depending on the degree of interrelation between the characteristic information of the document extracted by a characteristic information extraction unit and the classification-item-based information to realize automatic document classification in such a manner as to reflect the interest of a user.

Abstract: Techniques are provided for managing caches in a system with multiple caches that may contain different copies of the same data item. Specifically, techniques are provided for coordinating the write-to-disk operations performed on such data items to ensure that older versions of the data item are not written over newer versions, and to reduce the amount of processing required to recover after a failure. Various approaches are provided in which a master is used to coordinate with the multiple caches to cause a data item to be written to persistent storage. Techniques are also provided for managing checkpoints associated with the caches, where the checkpoints are used to determine the position at which to begin processing recovery logs in the event of a failure.
