Application of the mivar expert system to evaluate the complexity of texts

Reading and writing texts remains the basis for people's communication and training. A text is used for attracting people and describing various services and products. The number of texts is constantly increasing, which creates the problem of automated assessment of the texts complexity, their quality and the possibility of understanding by the target audience. Determining the complexity of texts is an important procedure that can be automated and used the following well-known methods for evaluating the texts complexity: automatic readability index ARI, Coleman-Liau index, Flesch readability index, DaleChall formula, SMOG test.
The problem of the texts complexity determining is relevant, important and practically significant. To assess the simplicity of the text for the reader's understanding, a mivar expert system for evaluating the complexity of texts has been created. The scientific novelty of the project is as follows: the formalization of decision-making and information processing tasks for assessing the texts complexity has been carried out; a new mathematical model of the mivar bipartite network including five procedures for assessing the texts complexity for the subject area "text complexity assessment" has been developed; a new problemoriented decision-making system for determining the texts complexity was developed.
The created mivar expert system for assessing the texts complexity can be used to work with texts in various fields of activity: compiling automated textbooks, instructions, technical works descriptions, writing texts for SEO in the development of web sites. The evolution of mivar networks allows us to add new ways and methods for evaluating the texts complexity to our project.
