In my country, 80% of social information resources, more than 3,000 databases have mastered in the hands of government departments. According to UNESCO research reports, 80% of social information mastered by government departments is valuable. That is to say, the government who has more than 60% of value information resources is the largest owner of China's information resources, and this part of the valuable information resources are not fully utilized. This is because these valuable information resources are distributed in the form of non-structural or semi-structured forms such as web pages, documents, and the government agency website, government private network, user local machine, etc. Unable to integrate into a unified form and a unified interface for government staff and the masses. The importance of e-government is because government informationization is the bridge of economic informationization and social information, so the sharing of government information directly affects information sharing and in-depth use of information in the process of informationization, and is directly determined. The development depth and application of informationization.

WEB-based system management platform Baidu e-government information sharing solution adopts standard B / S architecture, system administrators can manage and system maintenance through the browser to log in to Web's graphics management industry, anytime, anywhere. Simple and easy, you can quickly get started without professional training. System Architecture Baidu Evasion Information Sharing Solution consists of multi-function module components such as information acquisition module, index module, web snapshot module, classification module, and publishing module. Each module is connected by a standard data interface, but it is relatively independent. The information acquisition module information acquisition module includes Spider components and File components, which are responsible for network information acquisition and file system information collection. Spider component: Spider component is used to import Internet / Intranet information into the information library, which uses a distributed tricyclic architecture, including content capture module (CRACT CENTER, EC), and distribution center Distribution Center, where Crawler and EC support multi-threaded, the distribution center is responsible for distributing content into index modules, cache, publishing modules, or database systems. FILE Components: File components are used to collect multiple document information in the intranet file system, which currently supports multiple file systems based on both MS Windows and Linux operating systems, including FAT32, NTFS, EXT, EXT16, EXT32, etc. The supported document type includes .txt, .rtf, .pdf, .doc, .ppt, and .xls, etc.. The index module information index module is responsible for parsing the various types of information collected by the acquisition module, and establishing an index for the user's quick retrieval query. The first creating an index: extracts the information source by the information acquisition module, transmitting the extracted information to the information index module to quickly index the obtained data information, establish a hard disk index. On the basis of establishing a hard disk index, start the retrieval service, the user can start searching information. Incremental real-time index: Baidu e-government information sharing solution uses a different real-time synchronization mechanism for different information sources, and immediately transmits the change (increasing, deletion, and modification) of the information it captures to the information acquisition subsystem, the system After the format is standardized (XML), submit to the information index for instant memory index, so that once it is collected, it can be retrieved immediately. Memory and hard disk index: Index consists of two parts. Part of the memory index is used to index real-time data. Part of the hard disk index is used to index a large amount of data accumulated in history. The retrieval work is completed by two partial indexes. The information index module selects the appropriate time to complete the merge of the memory index based on the database changes. The response of the user retrieved: When the user submits a retrieval, the retrieval has been retrieved by memory real-time index and hard disk index in the kernel. The search result is submitted to the user by retrieving the response interface. Web Snapshot Module Baidu WST unique web snapshot module can save the web page to be collected, as this page is used as a snapshot with the camera, so it is called a web snapshot. You can improve web access speed through web snapshots, users can quickly browse web content locally by browsing web snapshots. And in the case where the original web page cannot be accessed, web page information can also be learned through web snapshots. Classification Module Baidu E-Government Information Sharing Solution has two classification mechanisms with keyword classification and natural semantic intelligence classification, providing flexible and accurate classification results. Users can use one of the classification mechanisms or use two combinations. Keyword Category: Keyword classification is based on the user setting keyword, can use Boolean logic to establish keyword rules to implement categories. The classification mechanism is fast, high efficiency, flexible use, does not need to perform text training such as machine learning, can be used directly after the keyword setting is completed, and can be modified at any time, and modify the same.
