[0026] figure 1 A schematic flowchart of the test item matching method in the first embodiment of the present application is shown. As shown in the figure, the test item matching method in this embodiment mainly includes:

[0027] Step S11, divide the target text according to preset division rules, and obtain a text block sequence including a plurality of text blocks.

[0028] In one embodiment, the target text can be divided according to the horizontal lines in the target text, and a text area composed of multiple text blocks arranged in sequence (for example, arranged according to the distribution position of each horizontal line in the target text) can be obtained block sequence.

[0029] Optionally, each generated text block may include at least one row in the target text.

[0030] Step S12, performing a partitioning step to generate a data partition covering a text block serving as an initial text block in the sequence of text blocks.

[0031] Optionally, the first te...

[0048] figure 2 A schematic flowchart of the test item matching method according to the second embodiment of the present application is shown. Such as figure 2 As shown, the test item matching method of this embodiment shows figure 1 An exemplary processing flow of step S11, which mainly includes:

[0049] Step S21, preprocessing the source file based on the preprocessing rules to obtain the target text.

[0050] In this embodiment, the source document can be a paper test paper, for example, a Chinese test paper, an English test paper, or a test paper in any other language, which is not limited in this application.

[0051] Furthermore, the source file may be a picture format file or a text format file, wherein, when the source file is a picture format file, it may be converted into a corresponding text format file through an image-to-text conversion technology.

[0052] For example, the source file in picture format can be obtained by photographing the test paper with a...

[0060] image 3 A schematic flow chart of the test item matching method according to the third embodiment of the present invention is shown. As shown in the figure, the test item matching method of this embodiment shows figure 1 An exemplary processing flow from step S12 to step S17, which mainly includes:

[0061] In step S301, the first text block in the text block sequence or the text block satisfying the designation of the preset instruction is used as the initial text block.

[0062] Optionally, the text blocks can be sorted according to their positions in the target text, and the first text block can be used as the initial text block to perform test item matching on the target text from the beginning.

[0063] For example, the text block corresponding to the first row of the target text may be used as the initial text block.

[0064] Optionally, according to the preset instruction, one or more text blocks satisfying the preset instruction in the text block sequence ma...

Abstract

A test question matching and test question splitting method, device and computer storage medium, including dividing the target text to obtain a text block sequence, performing a partitioning step to generate a data partition covering an initial text block in the text block sequence, and partitioning according to the data Determine the text similarity value of the current matching test question and the data partition from a plurality of preset standard test questions, and execute the block matching step to determine the text area to be recognized after the data partition in the text block sequence based on the text similarity value of the data partition Whether the block matches the current matching test question, if it matches, merge the text block to be recognized into the data partition and continue to execute the block matching step, if not, use the text block to be recognized as the initial text block and continue to execute Partition step. The embodiment of the present application matches and splits test questions in a dynamic programming manner, which can improve the accuracy of test question matching and splitting and reduce algorithm complexity to reduce equipment operating load.

Description

technical field [0001] The embodiments of the present invention relate to the field of computer data processing, and in particular to a test item matching and test item splitting method, device and computer storage medium. Background technique [0002] Marking is a kind of repetitive work. In the daily marking process, we only need a set of correct answers to test papers to correct all other papers. At present, the industry usually adopts text detection technology and text recognition technology to realize the automation of marking work, which can not only liberate teachers from a large number of repetitive tasks, but also improve the efficiency of marking work. It affects the accuracy of automatic marking. [0003] At present, when it is necessary to perform a topic-cutting operation on the test paper, it is generally realized by identifying and scanning the target test paper picture through the positioning block coordinates on the original test paper template. However, d...
