The invention relates to M2M systems, and specifically, to a method for querying semantics, resolving a problem of unnecessary network overhead in a semantic query owing to acquiring a remote semantic description resource unrelated to the present semantic query. In one embodiment of the invention, the method comprises: receiving a first semantic query request; employing two or more query triples in the first semantic query to query for a first queried object satisfying a first query rule; employing a partial query triple and a resource link query triple to query for a second query object of a remote semantic description resource and linked to an attribute indicated by the partial query triple, and to query for the attribute or a resource indicated by the partial query triple; and transmitting, to an apparatus storing the partial query triple linked to the attribute indicated by the partial query triple, a second semantic query request to determine whether the attribute indicated by the partial query triple satisfies a second query rule. The embodiment of the invention is suitable for a semantic query process.
Description
technical field [0001] The present invention relates to the technical field of Machine-to-Machine Communications (M2M), in particular to a semantic query method and device. Background technique [0002] Machine-to-Machine Communications (M2M) is a networked application and service centered on machine intelligence interaction. M2M technology realizes data communication without human intervention by embedding wireless or wired communication modules and application processing logic inside the machine, so as to meet users' informatization needs for monitoring, command and dispatch, data collection and measurement. At present, M2M technology has been applied in more and more industries and fields, such as intelligent transportation, agricultural irrigation, smart home, power grid, meter reading and other industries. In order to meet the needs of application services in different industries, M2M system operators develop a unified M2M platform to realize some public capabilities, ...
