Subclaims¶
Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q2 i? Uto et al. (2020) observed significant performance increases in essay scoring when hand-crafted features were concatenated with neural representations at the pre-output layer. → Xiaoyu Bai · Manfred Stede 2023

q2 · i? · review · r2
The survey reports Uto et al. (2020)'s hybrid essay scoring experiments, in which neural representations from BERT or LSTMs were concatenated with manual feature vectors; "they observed significant performance increases" when features were added. No effect size is printed.
"When hand-crafted features were added, they observed significant performance increases."
