Table 2 shows some examples from the corpus illustrating some typical types of ESL writing errors involving: (1) Verb-Noun Collocations (VNC) and (4) Adjective-Noun Collocations (ANC); (2) incorrect use of the transitive verb "attend"; (3) determiner (article) usage problems; and (5) more complex lexical and style problems.
a smaller t 3 can reduce recall, but can increase GP.
