Problems solved by technology

[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 subscribers who are not interested in events , so as to reduce the data distribution delay; efficient event routing technology is an important factor to ensure the real-time data distribution, however, there is a performance bottleneck in the upload bandwidth in the distribution of large data blocks

Embodiment 1

[0028] Embodiment 1: The online publishing information system is an information interaction system based on network technology. At present, the network-based application architecture basically uses a client / server (C / S) model. In this architecture, two equal and autonomous machines are used. When one party needs the service of the other party, the party requesting the service acts as a client to initiate a request to the server that provides the service, and the server responds to the request and processes it. The result is returned to the client. Even if the execution of this task does not require the result of the previous request as a prerequisite, the client needs to be in a waiting state until it gets the response from the server, and cannot continue to perform other tasks. This C / S model is relatively simple, and can meet most application requirements. It can reduce the coupling degree between different systems that need to work together, and improve the cohesion among ...

Embodiment 2

[0044] In the matching class, the classification attribute is established according to the classification number, the classification attribute is a typical word representing the classification number, and the typical word is a key predicate contained therein, and the described n groups under each classification number For the meta event and the complex event, a plurality of data groups are established, and each of the data groups represents a classification number, including n data groups, and each unit in the data group stores one of the For meta-events or complex events, the first unit of the first data group stores the classification attributes, and for a subscription message, first classifies words according to the filtering conditions specified by the subscription client included in it. Extract the keywords contained in it to find the matching data group, when the meta-event and the complex event in the data group and the subscription message are expressed as meta-events o...

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...
