  • Patent number: 10762144
    Abstract: A mechanism is provided for search engine domain transfer. The mechanism receives an input query to search a specialized domain from a user and performs a general-domain search based on the input query to generate a set of general-domain results. The mechanism generates a feature vector based on the general-domain results and generates a score for each document within the specialized domain based on the feature vector. The mechanism generates a ranked result set of documents based on the scores of the documents in the specialized domain and presents the ranked result set to the user.

  • Publication number: 20200233909
    Abstract: According to one aspect of the present disclosure a method and technique for managing data transfer includes receiving and storing a plurality of different data patterns anticipated to be encountered by a processor unit of a data processing system corresponding to a particular application being processed. Responsive to receiving a read request for data, the requested data is read from a memory subsystem, and the read data is compared by the memory subsystem to the stored data patterns. Responsive to determining that the read data matches at least one of the stored data patterns, the memory subsystem replaces the matching read data with a pattern tag corresponding to the matching data pattern. The pattern tag is transmitted over a communication link in response to the request.

  • Patent number: 10671134
    Abstract: A persistent memory storage system and method of operating. The storage system is embodied as memory module (e.g., a DIMM or PCIe card) in a host server and accessible via a first access path to/from the memory module. After a power failure at the host server, any authorized device, e.g., a second server, is configured to access and extract the retained memory at the failed host server via a secondary network-based access path (e.g., Ethernet connection). Power may be supplied to the memory module of the failed host server via a Power-over-Ethernet switch to support the secondary access path. A Power-over-Ethernet (PoE) switch may provide the necessary power to the memory module when power is unavailable from the host server and when any temporary power source is exhausted. A redundant power source and/or backup battery may supply the PoE switch. Such power sources and/or batteries can thereby provide backup power.

  • Patent number: 10664757
    Abstract: Mechanisms are provided for performing a cognitive operation. The mechanisms receive an original graph data structure comprising nodes and edges between nodes and activity log information for nodes of the original graph data structure. The mechanisms identify a set of nodes in the original graph data structure having a predetermined pattern of activity in the activity log information, and a set of edges between these nodes. The mechanisms calculate an importance weight for each edge in the set of edges and modify the original graph data structure based on the calculated importance weights for the edges in the set of edges, to thereby generate a modified graph data structure. The mechanisms then perform a cognitive operation based on the modified graph data structure. The set of edges may comprise actual edges between the nodes and/or potential edges between the nodes.

  • Publication number: 20200074332
    Abstract: A computer-implemented method includes determining a current state and a current context of an environment in which an automated agent runs to execute a contingent plan. The state indicates that one or more fluents of a plurality of fluents are true, and the plurality of fluents are associated with a contingent problem solved by the contingent plan. The context describes values corresponding to the one or more fluents. An action is performed with respect to at least a subset of the context. A nondeterministic effect of the action on the environment is evaluated, using a computer processor. The state is updated based on the nondeterministic effect. The context is updated based on the nondeterministic effect.

  • Patent number: 10572521
    Abstract: According to an aspect, automatically adding new concepts to a concept graph includes receiving a string of text, searching a corpus of data to locate additional text related to the string of text, and extracting concepts from the additional text. The extracted concepts include a subset of concepts in the concept graph. The adding new concepts also includes determining whether the string of text should be linked to an existing concept in the concept graph, performing the linking based on determining that the string of text should be linked to the existing concept in the concept graph and, based on determining that the string of text should not be linked to an existing concept in the concept graph, adding a new concept to the concept graph. The new concept is associated with the string of text.

  • Publication number: 20200050616
    Abstract: According to an aspect, searching, recommending, and exploring documents through conceptual associations includes a method for receiving a plurality of documents and extracting concepts from each of the documents. A degree of relation between each of the documents and concepts in a knowledge base is calculated. The method also includes, in response to receiving a query, determining one or more concepts from the query. For each of the concepts, a list of documents having a highest degree of relation to the concept is retrieved. The method also includes outputting a list that is responsive to the one or more retrieved lists.

  • Patent number: 10546247
    Abstract: An approach is provided in which an information handling system trains multiple classifiers using a set of training samples. The information handling system selects a leader classifier from the multiple classifiers that generates the most amount of correct decisions corresponding to the set of training samples. Next, the information handling system identifies an endorser classifier from the multiple classifiers that generates the highest proportion of correct decisions among the endorser classifier's decisions matching the leader classifier's decisions, and combines the leader classifier and the endorser classifier into a combined classifier stage. In turn, the information handling system utilizes the combined classifier stage to process inquiries and generate results.
