Intelligent Language Tutoring
An intelligent language tutoring system (ILTS) is an AI based system that provides customized instructions or direct feedback to students while they are practising their language skills. An ILTS generally supports the idea of "learning by doing", and often does not explicitly state the linguistic rules that support a particular pattern. Recently, the AI Lab's language game framework has been applied in the field of language tutoring where students play language games with a tutor, that can monitor their performance and modify the pace of the games accordingly. The FCG meta-layer (see Technique "Meta-layer Reflection") is used here to ensure robust parsing of student input and allows for an open-ended grammar that changes over time.
