Abstract: A system for applying an artificial intelligence engine to affect course corrections and influence outcomes of a meeting may include a network interconnecting a facilitator device, a teammate participant device, and a computing system operating a recurrent neural network. The facilitator device may receive parameters of a meeting including one or more of a meeting start time, a meeting location, a meeting duration, a meeting topic, and a list of teammate participant names. The teammate participant device may be a binary meeting score indicating if the meeting was either productive or not productive. The computing system may correlate the meeting score with the meeting parameters to create parameter scores. As scores are stored in the memory of the computing system, over time, the recurrent neural network may transform the parameter scores into parameter suggestions which may be conveyed to a meeting facilitator in real time.

A method includes converting (i) a multi-way theta join query into a multi-way interval join query, and (ii) one or more items of data associated with the multi-way theta join query to one or more items of interval data; executing the multi-way interval join query on the one or more items of interval data via MapReduce to generate an output, wherein the output comprises a set of multiple responses to the multi-way interval join query; and processing the output to generate a solution to the multi-way theta join query, wherein said processing comprises discarding each response from the set that does not satisfy the multi-way theta join query.

Abstract: Methods and arrangements for measuring similarity with respect to moving object trajectories. First and second moving object trajectories are input, each trajectory being defined by at least two spatial dimensions and a temporal dimension. At least one segment is defined with respect to each trajectory, each segment being defined between two defining points. At least one segment from the first trajectory is matched with at least one segment from the second trajectory. A spatial distance and temporal distance are each computed between the at least one segment from the first trajectory and the at least one segment from the second trajectory. The spatial distance and temporal distance are combined to provide a measure of a spatio-temporal distance between the at least one segment from the first trajectory and the at least one segment from the second trajectory. Other variants and embodiments are broadly contemplated herein.

Abstract: Search results are provided for a search query. A search query including an entity and entity type is received. The entity is parsed into semantic components. Variants are generated based on input from auxiliary information and user configuration information for each of the semantic components. The entity is recomposed in different morphological forms from different variants of the semantic components. At least one morphological form for the entity is presented as a search result.

Abstract: Methods and arrangements for segmenting log records. A log file is received. Candidates for a sequential pattern within the log file are automatically discerned, and, for each candidate, a likelihood is estimated that it represents a boundary within the log file.

Abstract: An embodiment provides intermediate data derived in the form of column stores which are in turn based on hierarchical data stores. This intermediate data represents a reduced subset of data matched appropriately to a query (or modified query) such that the amount of data handled in a query processing task on large data is greatly reduced. An embodiment may appropriately choose column data stores and/or modify queries in order leverage parallelization techniques such as map-reduce in order to query large data. The result is the ability to query large data stores in parallel while reducing the amount of data that must be handled.

Abstract: Embodiments of the present invention provide an efficient and scalable scheme for role-based access control to resources. The resources are assigned a protection class. Resources in the same protection class share the same access control policy. Permissions granted to various roles are then defined based on privilege sets and protection classes. Accordingly, the permissions of a role can be dynamically determined at runtime. Furthermore, as new resources are added, they can be assigned to a pre-existing protection class. The new resource may thus automatically inherit the various permissions and roles attached to the protection class.
