Abstract: Systems and methods are disclosed for efficiently indexing stream data to facilitate full-text search of the stream data. A stream comprises large amount of data, only some of which is deemed useful for full-text search indexing. An administrator can specify an indexing specification for a stream. The indexing specification can specify one or more sub-streams within the stream for indexing, and/or specify one or more time intervals of stream data for indexing. A query against the stream can specify the indexing specification to use to index the stream before returning results for the query. The query can alternatively specify an indexing specification to apply to a previously indexed stream. Full-text search indexes generated using an indexing specification can return results that are more relevant to a user because the results are more narrowly focused than an index of, e.g., the entire stream.

Abstract: Methods, apparatus, systems, computing devices, computing entities, and/or the like for a hybrid question-answering (QA) application are provided. The hybrid QA application includes both a retrieval QA application and a deep QA application, as well as a question classification model that determines whether the retrieval QA application or the deep QA application can generate a better answer to an input question.

Abstract: Systems and methods are disclosed for efficiently indexing stream data to facilitate full-text search of the stream data. A stream comprises a plurality of intervals of log data records. An interval of log data records are indexed. The index and log data records for the interval are written to an indexed stream data file. The index for each interval contains pointers to the terms in the log data records for the interval. After a number of intervals of index and log data records have been written, a merge operation can merge the number of intervals of index into a single merged index. The merged index and intervals of log data records are written to the indexed data stream file. A full-text search index is generated by traversing and merging the interval indexes for the data stream.

Abstract: Techniques disclosed herein describe a client and/or server process for managing Information Technology (IT) assets, such as servers and storage devices. The process dynamically generates customized information objects based on subscription requests. A client generates a request for information. The request specifies information associated with a specific managed entity or IT resource. A server that monitors the specific managed entity does not maintain such information in an existing information object. Information associated with the specific managed entity can be performance information, health information, usage information, and the like. A notification manager receives the request and identifies that existing subscription resources don not contain the requested information. The notification manager generates a new information object that contains the requested information, and notifies the client.

Abstract: Example embodiments of the present invention relate to a method, a system, and a computer program product for data analytics. The method includes receiving a plurality of first data streams from respective managed elements in a network and partitioning data of the plurality of first data streams according to an attribute regarding the data into a partitioned second data stream. The partitioned second data stream then may be streamed toward a data analytics platform for consumption by the data analytics platform. In a preferred embodiment, WebSockets are used.

Abstract: An information processing system comprises a system management tool, a managed system and a classifier. The system management tool receives a result of a situation classification operation from the classifier, and automatically takes a management action relating to the managed system based at least in part on the result of the situation classification operation. The situation classification result may be determined by monitoring operation of the managed system in a situational state space having dimensions that characterize operating conditions of the system, and identifying a current state of the system in the situational state space. The management action automatically taken by the system management tool may comprise, for example, setting at least one policy for the managed system by selecting and deploying a particular one of a plurality of policy sets responsive to the result of the situation classification operation.

Abstract: An apparatus and method for service classification are provided. The apparatus and method make use of canonical service descriptions which designate minimum requirements for a service to be classified into a corresponding classification. Based on the canonical service description, it can be determined whether a service that wishes to be classified into a particular classification of a taxonomy on a service broker meets the minimum requirements for that classification. Furthermore, the use of canonical service descriptions ensures that all services classified into a particular classification have a minimum level of functionality that will allow them to function properly when invoked.
