Error-Analysis
Abstract:
One of the main areas of applying CL methods to CALL has been the analysis of learner input. The idea is that the "deep" linguistic analysis of the input allows a precise characterization and adequate feedback of the errors the learner has possibly made. This has been tried on almost all linguistic levels from phonology to semantics. Additionally the deep analysis may allow an advanced type of exercise with almost free formed learner input.
In this chapter the use of statistical methods such as the mentioned LSA for an evaluation of learner input is excluded.

Error-Analysis PhonologyError-recognition in phonology has not been done to a large extend possibly due to the general difficulties recognizing speech. There has been only one large-scale project on this topic.
Error-Analysis MorphologyError-recognition in morphology has even seen less attention than phonology. However the identification of orthographic errors is an important research area.
Error-Analysis SyntaxAs mentioned in the introduction error recognition in morpho-syntax has been the area with the most research. However even though large-scale grammars are available morpho-syntax is still a difficult field.
Error-Analysis SemanticsError-recognition on the semantic level is especially difficult as a system would ideally need a complete representation of the world with inferences possibilities. Therefore the domain is usually restricted in order to be able to model all relevant world properties.
