Abstract
A corpus is provided of language usage by non-native users of the language. Characteristics of the corpus are measured and used to create a language usage classifier for indicating non-native usage of the language. Once the language usage classifier is created, a natural language input may be entered, and the characteristics thereof measured. These characteristics are then compared with the indicators of non-native usage, thereby detecting non-native usage. The evaluation of non-native usage may be used as a versatile foundation to enhance a wide variety of tools and applications dealing with user interaction in languages other than their native language.
