Figure 6
A line graph compares the performance of different models based on Avg Similarity Score, Precision, Recall, and F 1 Score. The horizontal axis represents the models: R A K E, T F I D F, Y A K E, Key B E R T, and Key Dist I T F. The vertical axis represents the scores ranging from 0.750 to 0.900. The Avg Similarity Score line, represented by blue circles, shows an upward trend from R A K E to Key Dist I T F. The Precision line, represented by red squares, also shows an upward trend and is consistently higher than the other scores. The Recall line, represented by green triangles, follows a similar upward trend but is slightly lower than Precision. The F 1 Score line, represented by yellow diamonds, shows a gradual increase and is generally lower than Precision and Recall.Key concept extraction from student answers
