Description

A search-based question bank system and its establishment and application methods

technical field

The invention relates to a question bank system, in particular to a search-based question bank system and its establishment method and application method.

Background technique

At present, hundreds of millions of trees need to be cut down for the amount of paper used for examinations in the country every year. The disappearance of trees from the earth will have a huge impact on the environment, society, and economy, especially the environment. With the continuous popularization of the network, it will become a trend to develop a question bank system for network examinations, which also plays a key role in environmental protection.

The search-based question bank system has the following research significance for today's teaching examinations, teaching construction, and environmental protection: the question bank system reduces the influence of subjective factors on the questions, and the content of the test questions is innovative. Automatic randomness reduces user workload, improves user productivity, and provides support for other aspects of construction. The online examination feature of the question bank system has greatly reduced the use of paper in schools, which is of great help in preventing excessive deforestation of forests, and has played a somewhat small role in environmental protection that cannot be underestimated.

At present, although there are some question bank systems on the Internet, at present, most of the question bank systems are dedicated to question bank management, and the content of the question bank in these question bank systems is relatively old, the practicability is poor, and the generation of test questions is not random. Yes, the content of the test questions is not novel enough and often does not have the significance of the times.

Contents of the invention

The purpose of the present invention is to provide a search-based question bank system with novel test questions and various contents, its establishment method and application method.

To achieve the above object, the present invention adopts the following technical solutions: a search-based question bank system, said question bank system includes a server, a database module, a database platform and a search engine module, and said database module is built on the basis of the database platform , the database module and the search engine module are respectively connected to the server.

In the present invention, the database module and the search engine module are respectively connected to the server, the database module and the search engine module can be integrated, and the data can be crawled from the website while the test questions are issued, and the content is rich.

The database module includes a memory A and a memory B. The memory A stores keywords and test question tables, and the memory B stores website information tables. The memory A and the memory B are independent of each other, and realize the storage function of different information.

The server is Apache2.2, the database module is MySQL5, and the database platform is PHP5 platform.

The PHP source code is installed in the PHP5 platform.

The PHP source code is written based on the PHP language, because there are many website systems written in the PHP language in actual website development. The functions are relatively complete, mainly to achieve classification management, question bank management, test paper management, test paper review, home page label modification, member management, database backup and other functions. The test papers are displayed to users in the form of web pages.

The present invention is based on the establishment method of the question bank system of search, and it comprises the following steps:

1) Use the server, database module and database platform to build a basic website structure;

2) Install the search engine module, and link more than one website address in the search engine module;

3) Connect the search engine module and the database module to the server respectively;

4) Grab relevant test question information from the URL linked to the search engine module through keywords, and then store the relevant test question information and keywords into memory A of the database respectively.

The keywords are leaf nodes of the classification tree.

The present invention is based on the application method of the question bank system of search, and it comprises the following steps:

1) The search engine module is connected with the database module, and extracts keywords from the memory A of the database module;

2) The search engine module uses keywords as content to search through the websites linked to it;

3) The server matches the information searched by the search engine module with keywords, and saves the matched information;

4) The server compares the information retained in step 3) with the test question data table in the memory A of the database module, and judges whether the test questions are repeated. If it is repeated, delete it, and keep the unrepeated test questions;

5) The server stores the new test questions retained in step 4) into the test question data table in memory A of the database module;

6) The server randomly selects the corresponding test questions in the test question data table in the memory A according to the test question types to form the test paper.

In the present invention, search-based refers to searching for information matching keywords in a certain area (for example, in a certain website) based on a search method. Based on the fact that the search is carried out in a specific area, it is targeted, and at the same time, the diversity of information makes it random and innovative. Based on the search, use keywords to search for information that matches the keywords, automatically and randomly generate test questions, and search for keywords that are in the same category as the keywords as options according to the category of keywords. The traditional method saves the time of the questioner, and the same keyword can search for a lot of information. The content of the generated test questions is varied and colorful, the options are not fixed, and the test questions are all innovative questions. Search the question bank by the type of the test paper, search for the test questions that match the test paper type, and randomly select the test questions.

In the present invention, the meaning of a keyword is: a word or core content used when searching for matching information.

In the present invention, matching refers to using a keyword to search for matching information. If the information contains the keyword, it means that the keyword matches the searched information.

The present invention adopts the above design scheme, connects with the search engine module through the traditional question bank system, uses keyword search and the content of the same type as the keyword as the test paper option, breaks the traditional way of setting questions in the past, and saves the time of the question maker. And the same keyword can search out a lot of latest information in real time through the search engine module, the content of the test questions generated is varied and colorful, the options are not fixed, and the content of the test questions is relatively innovative; in this way, the server searches the database module by the type of test paper , you can search for test questions that match the type of test paper, and randomly select test questions; and the test bank system of the present invention reduces the influence of subjective factors on the question; the network test characteristics of the test bank system greatly reduce the use of paper in schools. It is of great help to prevent excessive deforestation of forests, and it has made a somewhat small contribution to environmental protection that cannot be underestimated.
