Embodiment 1
[0067] 1. Cloze question: A common question type in primary and middle school subjects, more common in English subjects, the number of small questions is usually 15 or 20, and each small question is a multiple-choice question, usually 4 options.
[0068] Such as figure 2 As shown, in the actual demand, in order to structure the original test text, the test text needs to be structured into two parts: "question stem + option". The stem of the question, including 15 or 20 underlined blanks, such as "Pressure mounted on Britain on Monday ttake action on___36___smoking with new research showing second-hand smoke_____37____about one worker each week in the hospitality industry". Among them, the format of the underlined space is "_number_", for this "_number_", it is necessary to call the "regular expression matching mode for filling in the blanks and underscores", so as to identify the underscores for filling in the blanks and obtain the processed question stem.

[0091] 1. Multiple-choice question: a question type in primary and middle school subjects, there are multiple options, and there is only one correct answer.
[0092] Multiple-choice question: A type of question in primary and middle school subjects, with multiple options and one or more correct answers.
[0093] Multiple Choice Multiple Questions (Information Matching Questions): A question type for elementary and middle school subjects, common in English subjects, such as choosing 5 from 7, choosing 4 from 5, etc.
[0094] see image 3 , compared with cloze questions, the structure of the original test text of single-choice questions, multiple-choice questions and multiple-choice multiple questions will be simpler. The regular expression matching pattern is also generic. It should be noted that multiple choice multiple questions also need to be renumbered from 1.
[0095] The following takes multiple-choice questions as an example to illustrate the structural process of th...

Abstract
The invention discloses a method for performing structuring processing on text information. The method comprises the following steps of 1) obtaining contents of the text information; 2) according to the contents of the text information, calling a corresponding regular expression matching mode; and 3) performing the structuring processing on the contents of the text information in the regular expression matching mode to obtain structured text information. By flexibly applying a regular expression, test question texts of single-choice questions, multiple-choice questions, multiple-to-multiple questions (information matching questions), cloze questions (selective fill questions) and the like can be structured, so that quick question input and intelligent typesetting are realized, batch test question importing time is greatly shortened, batch and high-speed test question importing is realized in a real sense, and a large amount of tedious manual operations are avoided.
Description
Technical field [0001] The invention relates to the field of information extraction, in particular to a method for extracting text information by using regular expressions to structure text and realize rapid entry and intelligent typesetting. Background technique [0002] With the advancement of computer and Internet technology, computer-aided teaching has developed rapidly. A very important aspect of computer-aided teaching is the electronic test question bank, which stores a large number of electronic test questions. However, there are a large number of test papers based on text or pictures in schools and enterprises. How to identify a large number of test paper information is a key step in the construction of electronic test question databases and an important research topic in computer-aided teaching. [0003] A major difficulty in identifying test paper information in text format is the unstructured test question file, which makes it impossible to perform structured ent...
