Abstract: In platform knowledge (110), a plurality of devices, a plurality of solutions by the plurality of devices, and a plurality of abstract concepts that associates the plurality of devices with the plurality of solutions, are indicated, and each device is correlated to one or more abstract concepts and each solution is correlated to one or more abstract concepts. In user knowledge (120), a user device which is used by a user, a user device solution by the user device, and a user device abstract concept which associates the user device with the user device solution, are indicated. A search unit (10) searches for at least one of: a device other than the user device, which is correlated to the user device abstract concept in the platform knowledge (110); and a solution other than the user device solution, which is correlated to the user device abstract concept in the platform knowledge (110).

Abstract: A similarity degree calculation device (1) includes a similarity degree calculation unit (19) and performs transfer learning with using a transfer source data candidate (2) and transfer destination data (3). The similarity degree calculation unit (19) finds a similarity degree between a transfer source data distribution and a transfer destination data distribution on a basis of a transfer source extremal value group and a transfer destination extremal value group. The transfer source extremal value group includes a transfer source extremal value indicating an extremal value of the transfer source data distribution indicating a distribution of a feature amount of the transfer source data candidate (2). The transfer destination extremal value group includes a transfer destination extremal value indicating an extremal value of the transfer destination data distribution indicating a distribution of a feature amount of the transfer destination data (3).

Abstract: A search device (10) acquires first data obtained by performing a basis transformation on a feature vector in a transfer source device (20) based on information content on each feature axis. The search device (10) also acquires second data obtained by performing a basis transformation on a feature vector in a transfer target device (30) based on information content on each feature axis. The search device (10) judges whether the first data and the second data are similar so as to judge whether the transfer source device (20) is appropriate as a transfer source.

Abstract: A similarity degree computation unit (211) computes a similarity degree between each of one or more partial ontologies in a first-system-oriented ontology and a benchmark ontology of a second system, as a similarity degree of each of the partial ontologies. A candidate extraction unit (212) extracts as an ontology candidate from the first-system-oriented ontology, a set of: each of partial ontologies having similarity degrees which satisfy a similarity degree condition; and a partial ontology for linking to each other the partial ontologies having the similarity degrees which satisfy the similarity degree condition. An ontology output unit (214) outputs, when the ontology candidate satisfies a constraint condition, the ontology candidate as a second-system-oriented ontology.

Abstract: Deterioration of the quality of service at an application level is minimized by performing communication control only when the density of mobile objects (11) in a management network is high. A communication control device (100) is installed in each of mobile objects (11) that acquire content data (141) from a content server (14). The mobile objects (11) constitute a management network for communicating with each other. A management unit (110) determines whether communication control when acquiring the content data (141) is to be performed, based on the density of the mobile objects (141) in the management network.

Abstract: A response depth control unit (104) acquires response depth which is a request for depth of a search by a semantic engine (105). Further, the response depth control unit (104) causes the semantic engine (105) to repeat the search until the depth of the search by the semantic engine (105) reaches the response depth.

Abstract: A cache generation instructing section of a mobile station transmits, as a download instruction, an instruction that downloads a data fragment distributed to a mobile body when the mobile body is traveling in a communication area from a contents server. In addition, a cache generation section of a distribution cache node that manages data distribution in the communication area downloads the data fragment from a contents server based on the download instruction and stores the downloaded data fragment in a cache management database of a storage section as a cache.

Abstract: A device ID inquiry unit transmits a device ID request containing an IP address as a communication address of a destination, and receives a communication device identifier from a communication device. A device ID determination unit checks whether or not the communication device identifier is the same device identifier as a device ID. If the communication device identifier is the same device identifier as the device ID, a public key acquisition unit acquires a device public key from the communication device, and a device certificate transmission unit transmits a device certificate containing the device public key to the communication device.
