Knowledge provider system and knowledge providing method utilizing plural knowledge provider agents which are linked by communication network and execute message processing using successive pattern matching operations

A knowledge provider system is configured as a plurality of data servers connected via a data communication network, which function as respective knowledge provider agents in response to information request messages sent from users of the network. Each agent holds a script which contains a knowledge base, and data defining predetermined message formats for respective types of messages and predetermined content formats for respective types of message contents which can be handled by that agent. A message received by an agent is pattern-matched against the message formats, if it is thereby found to be an information request message the message content portion is pattern-matched against the predetermined content formats, and if that matching is successful, the subject for which information is requested is pattern-matched against the contents of the knowledge base, to find a set of information corresponding to that subject. If any of the pattern matching operations is not successful, the agent originates messages for successively propagating the content portion of that information request message to other agents via the network. Obtained information is then sent back to the originating agent and hence to the user.

Automatic collecting method of high-resolution satellite remote sensing traffic flow information

The invention discloses an automatic collecting method of high-resolution satellite remote sensing traffic flow information. The automatic collecting method comprises the following steps of: A. pretreatment: registration of panchromatic images and a vector road network as well as panchromatic and multi-spectral images, road region division and double edge filtering strengthen; B. acquiring a vehicle sample characteristic value by visually judging a road region image obtained in the step one, and establishing a vehicle remote sensing image feature library; C. carrying out rough neural network vehicle extraction and fine facing objective vehicle extraction on the panchromatic images obtained in the step two; D. by utilizing a matching method relative to an image frequency domain, searching the vehicle position in fine extraction in the step three in multi-spectral images and carrying out matching; E. calculating a displacement amount of a same vehicle in the panchromatic and multi-spectral images according to the corresponding vehicle position obtained in the step three and the step four, thus estimating traffic flow parameter information; and F. verifying the traffic flow parameter information through precision evaluation. With the adoption of the method, static and dynamic traffic flow information in a large range series can be automatically and rapidly collected, the efficiency is high, and the method is simple and practicable.
