Embodiment Construction

[0026] Such as figure 1 , figure 2 As shown in , a semantic annotation method for educational resources extracts resource information from documents, videos, and picture learning resources to build a learning resource library;

[0027] Based on the domain ontology constructed by "Thesaurus of Subject Classification", the ontology construction tool Protégé4.2 is used, and the tag library is constructed using OWL DL language;

[0028] Complete the mapping between the learning resource library and the tags in the tag library by means of mapping, and extract the corresponding tagging information to build the tagging information library; in the tagging information library, the tagging information is the result of resource tagging, and the tagging information is defined as a triplet IA= {R, L, β}, where R stands for learning resources, which are actually resource extraction information; L stands for labels, which are meta-knowledge points extracted from domain ontology; β stands f...

Abstract

The invention discloses an educational resource semantic annotation method. For different learning resources, resource information is extracted and a learning resource base is constructed, mapping of labels inside a learning resource library and a label library is achieved in a mapping mode, corresponding labelling information is extracted to be stored inside a label information base, and accordingly multi-label labelling of the learning resources is achieved. According to the educational resource semantic annotation method, experience of teachers and student grading are comprehensively taken into consideration, the resources and labels are labeled in a one-to-many mode, the corresponding semantic information is increased for the resources, and a user can accurately search the required resources.

Description

technical field [0001] The invention relates to the field of semantic resource labeling methods, in particular to a semantic labeling method for educational resources. Background technique [0002] At present, resource annotation methods based on semantics can only target a specific type of resource, and cannot complete cross-media resource annotation. The commonly used semantic resource labeling method simply puts a label on a certain resource, without considering that there may be more than one label related to the resource. It is also related to the problem of coordinates and graphics movement. Existing labeling methods only give resources a certain label and only complete qualitative analysis, but do not conduct quantitative research on the relationship between resources and labels. [0003] For the massive growth of digital resources, most of the existing search methods do not consider the semantic information and the user's personalized characteristics, but mainly se...
