Embodiment Construction

[0029] Below we will further describe the technical solution of the present invention in detail through the accompanying drawings and examples.

[0030] A kind of incremental calculation method based on the concept tree of the college course setting of the present invention, now its invention principle and content description are as follows:

[0031] 1. Form background

[0032] A form background can be expressed as K:=(G, M, I), wherein, G represents the collection of all objects in the form background, M represents the collection of all attributes in the form background, Represents the relationship between objects and attributes, and G×M represents the Cartesian product of the set G and the set M.

[0033] Suppose K:=(G, M, I) is a formal background, if Define a pair of operators:

[0034]

[0035]

[0036] In the present invention, in order to distinguish the form background after the newly added object, the newly added object is set as new, and the form backgroun...

Abstract

The invention discloses an incremental concept calculation method for a college course system based on a concept tree. According to the method, firstly, the influence of newly added object nodes in a path tree on a concept is analyzed; secondly, according to the conversion relation of the path tree, the concept and a concept tree, the influence of newly added objects on the concept tree is obtained; finally, updated constraint conditions of the concept tree are given by analyzing the characteristics of the newly added objects, and concept tree updating is directly performed. The algorithm uses an object topology theory as the support, does not need actual operation object topology and has no hard requirement for a form background, and concept updating under dynamic data updating is achieved. By adopting the method, incremental form concept calculation is conducted on the form background composed by different semesters of learning courses and graduation requirement data of college students, different semesters of courses are gradually added into the composed concept tree, concept tree updating is performed to obtain the final updated concept tree, and accordingly knowledge systems of all the courses are obtained.

Description

technical field [0001] The invention relates to the field of formal concept analysis, in particular to an incremental concept calculation method for a concept tree-based college curriculum system based on object topology. Background technique [0002] "knowledge is power". The advancement of knowledge has promoted the development of history and human civilization. No matter what era, society and system all need educated people, people with knowledge, and people with potential. Knowledge is inseparable from education. Education is the foundation of a country. With the rapid increase in the popularity of higher education, as part of the higher education system, various colleges and universities are responsible for "cultivating high-quality talents, developing technology, and serving the society." arduous task. Taking "students" as the center, guided by "training goals" and "graduation requirements", and supporting the achievement of "graduation requirements" through "curric...
