Automatic question setting method about query type short answer question of English reading comprehension test

The invention discloses an automatic question setting method about a query type short answer question of an English reading comprehension test. The automatic question setting method comprises the four steps of natural language processing, testing centre selecting, interrogative sentence generating and synonymy rewriting. According to the automatic question setting method, natural language processing is conducted on an input article; then a testing center sentence is selected according to word frequency intensity, paragraph length and sentence meaning similarity; a declarative sentence is converted into an interrogative sentence according to the principle of Lexical-Functional Grammar; finally, synonym replacement and pronoun replacement are conducted on the interrogative sentence, and the query type short answer question is formed. According to the automatic question setting method, due to the fact that the testing center selecting and synonymy rewriting are added, the generated interrogative sentence can be applied to the reading comprehension test, due to the fact that the methods of limiting the vocabulary range and the sense range are adopted in the synonymy rewriting part, the bottle neck of low semantic disambiguation precision can be broken through, and synonym replacement with a high accuracy rate is achieved. Due to the fact that an interrogative sentence part refers to syntax and semantic information, interrogative sentences with various types and high quality can be effectively generated.

Method and device for monitoring file change and server

The invention relates to a method and device for monitoring file change and a server and belongs to the field of computers. The method for monitoring file change comprises the steps that a monitoring catalog is obtained and all files contained in the monitoring catalog are scanned; each signature value corresponding to the corresponding scanned file is generated, so that a current file information set comprising file names and the signature values is obtained; the current file information set of the monitoring catalog is compared with a prestored reference file information set of the monitoring catalogue; whether the files contained in the monitoring catalog are changed or not is determined according to a comparison result. According to the method and device for monitoring file change and the server, through comparison between current file information and reference file information, whether the files are changed or not is determined, and the addition condition and the deletion condition of the files can be found in time. In addition, according to the method and device for monitoring file change, a user only needs to guarantee that an operation system can provide the file access function through the operation that all the files contained in the monitoring catalog are scanned and each signature value corresponding to the corresponding file is generated, so that the method and device for monitoring file change and the server are suitable for various operation systems and are wide in application range.

Establishment method and establishment system of label switching path

The invention discloses an establishment method of a label switching path (LSP). The establishment method of the LSP comprises the following steps: a head node of the LSP calculates information of a path through which an LSP to be established needs to pass according to management plane requests and network topology information; the head node of the LSP organizes a first signaling message which carries extended periodic line mark information to be sent to a downstream node in a hop-by-hop mode according to the obtained information of the path until a tail node of the LSP receives the first signaling message and allocates transmitting planes to be crossed successfully; after the tail node of the LSP receives the first signaling message and allocates the transmitting planes to be crossed successfully, a second signaling message is organized to be sent to an upstream node in a hop-by-hop mode until the head node of the LSP receives the second signaling message and allocates the transmitting planes to be crossed successfully. Simultaneously, the invention further discloses an establishment system of the LSP. By adopting the establishment system of the LSP, the periodic line heavy-route attribute is increased, the types of the LSP are enriched, and intelligent protection and recovery effects are achieved.
