摘要： The present invention provides a semantic information acquisition method and system, and corresponding keyword expansion and search methods and systems, comprising: searching for, then classifying an article; then, performing word segmentation according to the classified article to obtain the words in said category, and setting said category and words to serve as the semantic information of the keyword; also, a method and system using the semantic information acquisition method to expand a keyword, and a method and system using keyword expansion to perform a search. The described semantic information acquisition method effectively avoids the technical problems in the prior art of only being able to obtain semantic information of English vocabulary; and it also being impossible to classify semantic information based on category information. The invention is particularly suitable for searching using a keyword, searching a large number of texts, and organizing large amounts of related data and information.

摘要： A method and system for obtaining a knowledge point implicit relationship are provided; first, establishing a knowledge point explicit relationship map according to knowledge point explicit relationship strengths; second, computing according to said knowledge point explicit relationship map a simple path set of two knowledge points; then, computing the implicit relationship strength values corresponding to each simple path in said simple path set; further, comparing the relationship strength values of the simple paths and setting as the significant implicit relationship strength value the simple path relationship strength having the largest value also greater than a preset threshold value. The described solution effectively avoids the problems of only using the relationship strengths between knowledge points and the ratio of relationship strengths to obtain the implicit relationship of knowledge points, the manner of searching for an implicit relationship being insufficiently accurate, and not performing normalization processing on the relationship strengths.

摘要： A method and system for selecting an encoding format used for reading a target document are provided. The method comprises reading a reference document with at least one reference encoding format and determining all or some disorder code patterns obtained when reading the reference document with the reference encoding format; reading the target document with one encoding format each time; for each encoding format, comparing data generated when reading the target document with this encoding format and the determined disorder code patterns to determine disorder codes generated when reading the target document with this encoding format; counting disorder codes generated when reading the target document with each encoding format, and making a comparison to determine the encoding format used for reading the target document.

摘要： The present invention relates to the technical field of computer application, and more particularly to a method for allowing user access, a client, a server, and a system, for solving the problem that when a user accesses a server, it cannot be determined whether the user is allowed to continue accessing the server. The method comprises: a server receiving a type identifier and/or server identifier and user identity information sent from a client, for each application accessed by a login user, the client generating a type identifier and/or server identifier corresponding to the application; the server determining the number of type identifiers and/or server identifiers received for the user according to the user identity information, and determining whether to allow access of the user. The method can solve the problem that when a user accesses a server, it is determined whether the user is allowed to continue accessing the server.
