Embodiment Construction

[0041] The preferred embodiments of the invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the invention can be more easily understood by those skilled in the art, so as to define the protection scope of the invention more clearly.

[0042] The Word document test paper used in daily teaching in primary and secondary schools does not seem to have any special marks, but in fact the structure is still very clear. From the perspective of structural semantics, it is divided into test paper title, explanatory text, major title, sub-question title, question stem, Answers, analysis, etc., a common test paper structure model such as figure 1 .

[0043] The feature of document editing for primary and secondary school examination papers is that social science subjects are mostly text, but font settings often have various rich text formats, such as: bold, italic, emphasis, phonetic, circled, etc., while natural...

Abstract

The invention discloses a paragraph semantics-based middle and primary school test question segmentation and extraction method and system. The method comprises the following steps: reading charactersof each paragraph in a test paper document, and analyzing structural semantics of each paragraph by adopting a structural semantic regular expression matching rule; recording the paragraph structure of the whole test paper by adopting paragraph structure semantic coding specifications to form a paragraph structure semantic string; performing structure correction and structure division on the paragraph structure semantic string; and according to the record of the structure division, extracting a fixed format from the test paper document to form a formatted document of a single test question. According to the invention, a large number of test paper documents commonly seen in middle and primary schools are classified and concluded according to structural modes; according to the test paper document structure analysis method, a plurality of most common structure models are abstracted, and the document structure analysis method with high adaptability is designed, so that structured splittingand test question information segmentation and extraction of the test paper document are realized, and the test paper document structure analysis method has high expandability and wide test paper model applicability.

Description

technical field [0001] The invention relates to the technical field of question bank processing, and more specifically, relates to a method and system for segmenting and extracting test questions in primary and secondary schools based on paragraph semantics. Background technique [0002] The question bank plays an important role in all kinds of teaching evaluation work, especially in the teaching of primary and secondary schools, it is of great significance to automatically divide a large number of test papers into test questions, and then realize efficient database management. However, there is no uniform standard for editing test paper documents in the daily teaching of primary and secondary schools, and it is difficult to use a fixed pattern of test question splitting strategies to deal with a huge number of test paper documents. [0003] The feature of document editing for primary and secondary school examination papers is that social science subjects are mostly text, bu...
