Method for online distribution information system

Abstract

The present invention relates to a method for an online distribution information system. The online distribution information system comprises a plurality of distribution clients, a proxy network, a distribution / subscription module, a plurality of subscription clients, and a management cluster. The distribution / subscription module comprises a message memory, a message sectionalizer, a user subscription manager, and a message dispatcher. The method comprises the key process related to the system. According to the method disclosed by the present invention, in order to solve the problem of information resource understanding of the computer, the semantic technology is combined with the distribution and subscription system organically, and the intention of the distribution client and the subscription client can be grasped from the perceptive of the semantic layer, so that the distributed event can be more accurately matched with the requirements of subscribers, the matching quality of subscription and distribution can be improved, and the performance of the entire system can be improved.

Description

technical field

[0001] The invention relates to the field of computer networks, and relates to a method for publishing information systems on the Internet. Background technique

[0002] As the Internet becomes a ubiquitous computing and storage service platform, how to quickly and accurately distribute data generated by data sources to large-scale user groups with different interests is a key technical problem that needs to be solved urgently. Content-based publish / subscribe is becoming the main mode for data distribution because its loosely coupled communication mode is suitable for large-scale distributed systems and provides users with powerful semantic expression capabilities.

[0003] In order to achieve content-based elastic and scalable publish / subscribe services, the current technical challenges mainly include the following two aspects: using events to represent publishing messages and subscribing messages, and event matching technology can effectively filter out sub...
