Abstract: A method and system for tracking a course of a cable using electromagnetic waves. A first transceiver sends to a second transceiver a first signal wirelessly in a linear line. The second transceiver sends back to the first transceiver the first signal in the linear line. A first distance between the first transceiver and the second transceiver is determined by determining a total transmission time for a first wireless signal travelling from the first transceiver to the second transceiver and back to the first transceiver. A second signal, aligned with the first signal, is transmitted from the first transceiver into the cable. The second transceiver receives the second signal wirelessly from the cable. A second distance between the first transceiver and the second transceiver is determined by comparing a phase difference between the first signal received by the second transmitter and the second signal received by the second transmitter.

Abstract: A method, computer system, and computer program product for eliminating a redundant node from a knowledge graph is provided. A structural analysis of a knowledge graph is performed by determining that two nodes have a similar structure. An empirical analysis is performed by determining a search result correlation of potentially redundant nodes, said search result correlation comprising a correlation of search result nodes generated from different search queries to said knowledge graph or a correlation of search results due to selected search result nodes in subtrees of said potentially redundant nodes. Results of said structural analysis and said empirical analysis are combined to generate a redundancy confidence level value for two said nodes. One of said two nodes is determined as redundant. One of said two redundant nodes is removed from the knowledge graph.

Abstract: A computer program product, system, and method for building a knowledge graph may include receiving a plurality of new nodes, receiving a base knowledge graph having existing nodes selectively connected by existing edges, and superimposing the new nodes onto selected ones of the existing nodes of the base knowledge graph. The method may further include connecting the new nodes by creating a new edge with a new weight between at least two of the new nodes if corresponding existing nodes in the underlying base knowledge graph have a connection via zero or a predetermined maximum number of existing edges, wherein the new weight is determined based on the existing weights of the existing edges of connections between the corresponding existing nodes, and detaching the new nodes with the new edges from the base knowledge graph.

Abstract: A method and system for deleting a node of a knowledge graph may be provided. The method comprises receiving knowledge graph data comprising nodes and edges, determining a first relevance degree value for a node and a second relevance degree value for the node, combining the first and the second relevance degree value and marking the node as deletable if the final relevance degree value is above a predefined relevance threshold value. The method comprises further applying queries against the knowledge graph, wherein at least a certain number of such queries invokes accessing of a node, marked as deletable, revising at least one of the first and second relevance degree value based on the accessing of the node marked as deletable, and deleting the node, marked as deletable, if over a predetermined period of time queries against the knowledge graph invoke no access of the node marked as deletable.

Abstract: Methods, computer program products, and systems are presented. The methods include customer specific information exchange and an adjustment of the privacy level of this information. For this purpose an abstraction layer and an obfuscation module are introduced. Using a “fraud vector” a risk assessment is performed on the obfuscated transaction data.

Abstract: A method includes receiving a first query by a computing device and assigning the first query to a plurality of cognitive engines, wherein each of the plurality of cognitive engines include different characteristics for processing data. The method also includes, responsive to receiving a response from each of the plurality of cognitive engines for the first query, comparing the received responses from the plurality of cognitive engines. The method also included responsive to determining a difference between a first response from a first cognitive engine and a second response from a second cognitive engine is above a predetermined threshold value, performing a response mediation process until the difference is below the predetermined threshold value. The method also includes selecting a first final response from the received responses for the first query and the second query and displaying the first final response to a user.

Abstract: A cognitive hierarchical storage-management system receives feedback describing users' satisfaction with the way that prior data-access requests have been serviced. The system uses this feedback to associate each previously requested data element's metadata and storage tier with a level of user satisfaction. As feedback continues to be received, the system uses machine-learning methods to identify how closely specific metadata patterns correlate with certain levels of user satisfaction and with certain storage tiers. The system then uses these associations when determining whether it should migrate data associated with a particular metadata pattern to a different tier.

The image file includes digital image data and a plurality of data fields. A first data field of the plurality of data fields includes a first metadata. A rule set for modifying the first metadata is received. In response to determining that at least one rule of the rule set corresponds to the first metadata, the first metadata is encrypted based to create a second metadata. The second metadata is stored in the image file.

Abstract: Embodiments include a method and associated system and computer program product. A capacity utilization of an application system and a backup system for a first period of time is monitored, resulting in retrieving utilization statistics indicative of the capacity utilization. An application load score for the application system and a backup load score for the backup system are determined for several time slots of a backup schedule. For each time slot, a suitability score is determined, by combining the application load score and the backup load score. The suitability score is indicative of a suitability of the application system and the backup system in combination for execution of a backup during the time slot. A first time slot whose suitability score does not exceed a predefined threshold is selected. The backup is scheduled for the first time slot for the application system and for the backup system.
