    摘要： Among pieces of attribute information contained in a document, user-designated attribute information and other attribute information that may give additional value to the user-designated attribute information are accurately and efficiently presented. An attribute extraction apparatus includes a storage section that stores a document; and a computing section that executes a process for calculating a predetermined index on the basis of the document's structure with respect to a relationship between a plurality of pieces of attribute information described in the document, and a process for calculating an importance degree of each piece of the attribute information other than predetermined attribute information for the predetermined attribute information on the basis of at least one of the index and a predetermined statistical property with respect to a relationship between the predetermined attribute information and the attribute information other than the predetermined attribute information among the plurality of pieces of the attribute information.

    摘要： A technology is disclosed that makes it possible even for an analyst, who has poor knowledge relating to field data, to select and use analysis data in analysis. A data catalog automatic generation system that generates a catalog tag to be used to select analysis data from collected field data is configured such that, based on a set classification rule input, a relationship between an objective variable as an analysis perspective relating to field data and an explanatory variable or a causal relationship between a plurality of the explanatory variables is extracted, and based on a result of the extraction, a catalog tag of the objective variable and a catalog tag of the explanatory function are specified and attached.

    摘要： A converged system and migration method capable of preventing system performance degradation with respect to data transfer is proposed. A first calculation node continues executing I/O processing in response to an I/O request from an application; and, upon execution of the I/O processing, the first calculation node issues an I/O processing event notice indicating a transfer status of data on which the I/O processing has been executed. When receiving a migration command from a migration management unit, a second calculation node judges whether or not data stored in a first I/O node is data which should be transferred, based on the I/O processing event notice; and then transfers the data, which should be transferred, to a third calculation node.

    摘要： In a computer, a logical partition for calculation in which an OS and an application operate and a logical partition for storage for providing a storage function are constructed. In the logical partition for calculation, a device corresponding to a storage device is provided, while the logical partition for storage provides a volume. A memory space that can be shared by the both logical partitions is prepared, and management information describing a sorting destination or a sorting method of an I/O request issued by an application is provided in the memory. If the logical partition for calculation receives an I/O request from the application, the partition refers to the management information and sorts the I/O request to the storage device or the logical partition for storage. The logical partition for storage processes the received I/O request by the storage function and transmits the result to the storage device.

    摘要： A method for determining metadata propagation generated by an Extract, Transfer, Load (ETL) process. The method may include categorizing metadata given to data sources to generalize the metadata and categorizing the ETL process to generalize the ETL process; defining propagation rules for the generalized metadata and generalized ETL process; and generating metadata for ETL-converted data based on the categorization of the generalized metadata and generalized ETL process, and corresponding ones of the propagation rules.

    摘要： A first system receives values with identifiers of the values from one or more clients. The first system enters the values sequentially into a first data store. The first system associates each of the values with a sequence ID indicating a position in entry sequence of the values into the first data store. The first system transmits a first identifier of a first value and a first sequence ID associated with the first value to a second system. The first system transmits the first sequence ID and the first value to the second system after transmitting the first identifier and the first sequence ID. The second system holds the first identifier and the first sequence ID transmitted from the first system in a first queue. The second system enters the first value received after the first identifier from the first system into a second data store.

    摘要： A model creation supporting system executes: learning processing to create an inference model by performing machine learning on pieces of training data so as to specify a feature of each piece of the data, the inference model being designed to infer a label to be set to a piece of input data based on a feature of the piece of input data; and evaluation processing to determine validity of inference of the label in accordance with the inference model by determining a similarity between a feature of a given piece of data specified by inputting the given piece of data to the created inference model and the feature of one of the pieces of training data specified by the machine learning, and to output information indicating a content of the determination.
