Linguistic-Valued Intuitionistic Fuzzy Concept Lattice And Its Application In Intelligent Evaluation Of Educational APP

Artificial intelligence is a hot topic in current academic research field,and intelligent information processing is an important research topic in the field of artificial intelligence.The computer can intelligently deal with the reasoning and decision making problems with natural language in daily life,which is the intelligent embodiment of intelligent information processing.Fuzzy linguistic values can be aimed at the processing of the uncertainty problem with linguistic information.The concept lattice is a mathematical tool of data analysis and knowledge processing.Combining with linguistic-valued intuitionistic fuzzy lattice implication algebra and intuitionistic fuzzy concept lattice,we can effectively excavation data information and acquisition decision knowledge,which is widely used in medical diagnosis,education evaluation,information retrieval and other fields to make the computer more intelligently to deal with information.This paper deeply studies the linguistic-valued intuitionistic fuzzy concept lattice and applies it to the intelligent evaluation of educational applications.The main research results are as follows:In order to solve the decision-making problem with fuzzy linguistic-valued information,this paper proposes the linguistic-valued intuitionistic fuzzy formal context to reduce the data missing based on linguistic-valued intuitionistic fuzzy lattice implication algebra.Then we give the definition and operators of the linguistic-valued intuitionistic fuzzy concepts,and construct the linguistic-valued intuitionistic fuzzy concept lattice(LVIFL).Based on the linguistic-valued intuitionistic fuzzy concepts,the degree of similarity between two linguistic-valued intuitionistic fuzzy concepts is studied.Furthermore,the degree of similarity between the linguistic-valued intuitionistic fuzzy concept lattices is given.And the pattern recognition method based on LVIFL is proposed.The effectiveness and practicability of this method are illustrated by an example of diagnosis and recognition of Chinese medicine diseases.In order to improve the efficiency of knowledge information processing,this paper makes a deeply research on the rule extraction of the linguistic-valued intuitionistic fuzzy decision formal context.Firstly,the linguistic-valued intuitionistic fuzzy decision formal context is proposed,and the construction operator of the linguistic-valued intuitionistic fuzzy decision formal concepts is given.Based on the concept set which from linguistic-valued intuitionistic fuzzy decision formal concepts,we obtain a rule set of the linguistic-valued intuitionistic fuzzy decision formal context.Combining with the confidence and support of linguistic-valued intuitionistic fuzzy decision rules,the method of rule extraction is studied.Finally a practical example concerning the personal finance investment decision is given to illustrate the applicability and advantage of the proposed approach.In view of the wide variety and uneven quality of educational applications at present,this paper constructs an intelligent evaluation system for educational applications evaluation.Due to the incomplete collection of information in real life,the incomplete linguistic-valued intuitionistic fuzzy decision formal context is proposed.According to the different evaluation results of each learner the incomplete linguistic-valued intuitionistic fuzzy decision formal context will be completed.Then,it is applied to the educational applications intelligent evaluation system.Combining with the rule extraction method,the system evaluates educational applications to help learners to make effectively selection of educational applications.
