Information Collection Research Which Is Based On Dynamic Field Of Knowledge And Implementation

Dynamic information as a huge resource library, the Internet has become the kinds of institutionsis one important channel for information collection, information gathering topic has become veryimportant. However, the current network-oriented information is based on keyword search technology,collecting the results of fragmented, isolated content, large volumes of data. This paper, based onmission requirements in the project, proposed a system based on dynamic domain knowledgethematic information collection methods, this method is based on the basic areas of knowledge,combined with the discovery of key words, and experts in the field intervention to achieve, in order toachieve thematic information collected dynamic adaptability, to improve the quality of a goodcollection of research significance.This first update of the information collection and information-based theoretical approaches andresearch status of the Introduction, describes the basic principles of Web information gatheringmethods and information updates and related technologies. And thematic content for the Webinformation collection strategy design, mainly the acquisition strategy for the general web design,forum design data collection strategies, domain knowledge of the updated design. With relatedacquisition strategy, the system needs analysis, analysis of existing areas of knowledge applied to thelack of thematic information collected above, then the system analysis and design, including theestablishment of areas of knowledge, systems analysis of functional structure, which core of thesystem’s domain knowledge is pre-semi-automated system for updating and further enhance thethematic information collected to adopt all rates, and finally realize the system, domain specificknowledge of the topic of national defense information collection designed experiment, the proposedprogram design for testing.The main contribution of this paper lies in the traditional topics of information collected based onthe different information sources and areas of knowledge acquisition strategies of semi-automaticupdate algorithm, and applied in the system test, presented to the user in the actual use of therecognition process.
