WEB-based mathematical formula editing system and method

Abstract

The invention provides a WEB-based mathematical formula editing system, which comprises an edit module, a conversion module, a communication module, a WEB server and an analysis module, wherein the edition module is used for editing a mathematical formula by inputting mathematical symbols in an edit window of a WEB browser, and the mathematical formula is represented by HTML; the conversion module is used for compressing and converting the mathematical formula into a code in a text format; the communication module is used for sending the code of the mathematic formula generated by the conversion module to the WEB server for storage; the WEB server is used for storing the code of the mathematic formula; and the analysis module is used for analyzing the code of the mathematic formula downloaded and reducing the code into the mathematic formula represented by the HTML. The mathematic formula obtained by the analysis module can be transmitted to the edit module, and is used for formula modification. The invention also provides a WEB-based mathematical formula visual editing method. The editing system is operated in the WEB browser, and a computer terminal is not required to be provided with any plug-in, so that the edition and modification of the mathematic formula are more convenient and simple.

Description

technical field [0001] The invention relates to a computer editing technology for mathematical formulas, in particular to a WEB-based mathematical formula editing system and its realization method. Background technique [0002] With the rapid development of the Internet, obtaining, publishing and sharing information resources through the Internet has become a basic means for people to work, study, research and communicate. Mathematics is the basic language of science, so for the fields of education and scientific research, the input and editing of mathematical formulas is the most important input and editing tool besides the input and editing of ordinary text. However, since the birth of the Internet at the end of the last century, the problem of quickly inputting and editing mathematical formulas online based on the WEB has not been systematically and thoroughly resolved, which seriously restricts the development of online education, academic exchanges and document records....

Problems solved by technology

However, since the birth of the Internet at the end of the last century, the problem of quickly inputting and editing mathematical formulas online based on the WEB has not been systematically and thoroughly resolved, which seriously restricts the development of online education, academic exchanges and document records

However, the modified formula remark information is generally text-based and non-visual, and the formula remark information needs to be learned before it can be understood and used, which is inconvenient for use and promotion

At present, all browsers support the display of common image formats, but there will be some problems when using images. Although high-quality images can be printed clearly, they will affect network transmission, while low-quality images cannot be displayed or printed clearly.

[0005] MathML is an international standard for describing mathematical formulas. At present, some browsers such as Firefox and Opera have begun to support MathML parsing and display, but MSIE, which accounts for 90% of the market, does not support MathML. Users need to install plug-ins to edit and display mathematics formula

Judging from the situation included in the W3C (Internet Consortium) website, the current solution to display and edit mathematical formulas under the mainstream IE browser requires the installation of additional software or plug-ins without exception.
