Language Beyond the Source
Model description
This model is a fine-tuned version of microsoft/deberta-v3-large on a dataset consisting of 4,620 summaries, scored on an analytic rubric by expert raters. This model predicts the raw score for Language Beyond the Source. The rubric is as follows:
LANGUAGE BEYOND THE SOURCE
- 1 Point: Summary shows a very basic understanding of lexical and syntactic structures.
- 2 Points: Summary shows an understanding of lexical and syntactic structures.
- 3 Points: Summary shows an appropriate range of lexical and syntactic structures.
- 4 Points: Summary shows an excellent range of lexical and syntactic structures.
It achieves the following results on the evaluation set:
- Loss: 0.1817
- Mse: 0.1817
- Rmse: 0.4263
On set of summaries of sources that were withheld from the training set, the model achieved the following results:
- Rmse: 0.4220
- R2: 0.6236
Intended uses & limitations
This model is intended to be used to provide feedback to users of iTELL, a framework for generating intelligent educational texts.

Training and evaluation data
Seventy summaries in the training set had Language Beyond the Source scores of <1, which is outside of the rubric. These summaries were removed from the training and test sets.
