Distributed information collection method and system

Abstract

The invention discloses a distribution type collection method and system for information which solves problem that too long collection period can not guarantee timeliness and effectiveness of information collection, promotes information collection and updating speed, reduces collection cost. The method comprises: establishing collection task by configuring collection parameter, dividing task to multiple task packet according to collection parameter; server terminal dispatching distribution type client terminal and sends collection parameter and task packet to request client terminal; client terminal performs collection task and acquires web page according to collection parameter and collects needed information. The inventive method provides a highly effective and stable information collection scheme and task dispatching scheme, fully utilizes network resource and computing resource, effectively promoting information collection efficiency and data updating speed, guarantees effectiveness of collected information by utilizing space information quantity distributed in network and combining information extraction technology and distribution type technology.

Description

technical field [0001] The invention relates to spatial information processing technology, in particular to a distributed collection method and system for spatial information. Background technique [0002] As the most frequently used and widely used information in spatial information, the collection and update technology of POI information is an important issue affecting the application of GIS. The point-of-interest information refers to information related to spatial locations that people are interested in or useful to people, such as restaurants, shopping malls, residential areas, and the like. The purpose of collecting point-of-interest information is to use it in the map making process, and finally reflected in spatial information services such as network map services and navigation services. Map producers will use the POI information to compile maps, and end users can use these POI information through web map services, car navigation systems, or location-based services...
