CIC researchers Ming Liu and Simon Buckingham Shum have continued their longstanding collaboration with Cherie Lucas (UTS School of Pharmacy) and a new collaborator, Efi Mantzourani (U. Cardiff). The team has already accomplished a world first for UTS — providing instant feedback to students on their reflective writing. Building on their grammar-based approach, they have now reported the first steps towards training their text analysis infrastructure to classify student writing purely by analysing examples.
In this paper, several statistical machine learning classifiers were trained on a corpus of 301 reflective statements, using emotional, cognitive and linguistic features from the Linguistic Inquiry and Word Count (LIWC) and reflective rhetorical features from Acawriter developed by CIC. The study results showed that a Random-forest classifier performed well on distinguishing between good and poor reflective writing.
