Method for classifying Chinese webpages based on keyword frequency analysis

The invention relates to a method for classifying Chinese webpages based on keyword frequency analysis. According to the analyzed keywords of the Chinese webpages and a Chinese classification subject thesaurus, the fuzzy matching of the classification of the Chinese webpages is carried out; and through the obtained HTML source code of the webpage, the webpage is pretreated. Through the testing and analysis, a regular expression filter is utilized to filter noise information; a Chinese text of the webpage is extracted; then, through a word classifier and a keyword frequency analyzer, the extracted Chinese text information is subjected to word classification; through the weighed ranking of the word in the text and fuzzy classification algorithm of the webpage, the class ranking of the class which the webpage keyword belongs to is obtained; and the keywords ranking in the several tops are selected and subjected to calculation of membership rate to obtain the fuzzy matching result of the class which the webpage belongs to. The method is favorable for organizing mass information on the Internet with high efficiency and is used for interestingness analysis of Internet users, catalogue updating of search engines, mining of Web contents, online document management, and digital library construction.

Multimedia integration description scheme, method and system for MPEG-7

The invention provides a system and method for integrating multimedia descriptions in a way that allows humans, software components or devices to easily identify, represent, manage, retrieve, and categorize the multimedia content. In this manner, a user who may be interested in locating a specific piece of multimedia content from a database, Internet, or broadcast media, for example, may search for and find the multimedia content. In this regard, the invention provides a system and method that receives multimedia content and separates the multimedia content into separate components which are assigned to multimedia categories, such as image, video, audio, synthetic and text. Within each of the multimedia categories, the multimedia content is classified and descriptions of the multimedia content are generated. The descriptions are then formatted, integrated, using a multimedia integration description scheme, and the multimedia integration description is generated for the multimedia content. The multimedia description is then stored into a database. As a result, a user may query a search engine which then retrieves the multimedia content from the database whose integration description matches the query criteria specified by the user. The search engine can then provide the user a useful search result based on the multimedia integration description.

Occlusion-eliminating radiation energy density simulation method in tower-type solar thermal power generation system

The invention discloses an occlusion-eliminating radiation energy density simulation method in a tower-type solar thermal power generation system. The method comprises the following steps: (1) an axially-parallel large bounding box for an overall heliostat field is built; (2) the large bounding box is equidistantly divided along a heliostat distribution direction; (3) light poles reflected and incident by the heliostats are modeled; (4) as for each light pole, an intersected grid intersected with the light pole is found out; (5) intersection determination is carried out on the heliostats in the intersected grid and the corresponding light poles; (6) shadow is converted into occlusion; (7) a corresponding relationship between a receiving panel and streamline drawing cache is built; (8) the heliostats and the occlusion thereof are projected on the receiving panel; (9) a sequence of heliostats in the streamline and the occlusion heliostats is organized and depth valuation is carried out; and (10) an occlusion area with reflection light spots is eliminated and is parallelly accumulated to cumulative cache. The quick simulation method of the invention can effectively improve the calculation accuracy and the efficiency, and the simulation result is more authentic and reliable.

Maritime search and rescue system based on BeiDou satellite navigation and positioning

The invention relates to a maritime search and rescue system based on BeiDou satellite navigation and positioning. The maritime search and rescue system comprises an individual device, a command center and a search and rescue device. A BeiDou satellite positioning module and a first wireless communication module are arranged on the individual device and the individual device is used for sending position information and ID information to the command center. The command center comprises a second wireless communication module, a first GIS electronic map and a first judgment module. The position information and the ID information are reflected on the GIS electronic map by the command center, and the command center dispatches the corresponding search and rescue device to conduct rescue. A third wireless communication module, a second GIS electronic map and a second judgment module are arranged on the search and rescue device and the search and rescue device is used for receiving help seeking information sent within the range of 40 kilometers, and reflecting the help seeking information on the second GIS electronic map. By the adoption of the maritime search and rescue system based on BeiDou satellite navigation and positioning, an emergency reaction action to a maritime emergency can be rapidly, orderly and efficiently organized, persons in distress are rescued, extension of the maritime emergency is controlled, loss of life, personal injuries and property loss caused by the maritime emergency are reduced to the maximum extent.
