We consider the use of text processing and analysis methods to create an automatic knowledge control system that evaluates the learning and understanding of educational material based on written answers. This system can be used to assess the effectiveness of educational programs and identify areas where students need additional support. The system can also provide personalized feedback to students, helping them to improve their understanding of the material. By automating the evaluation process, the system can save time and resources for educators, allowing them to focus on more complex tasks. The system can be used in various educational settings, including online courses and traditional classrooms. Overall, the automatic knowledge control system has the potential to revolutionize the way we evaluate student learning and understanding.
