Developing a context-supported Chinese grammar learning system in mobile environments

This work develops a context-supported Chinese grammar learning system on the Android platform for use by Chinese as a Foreign Language (CFL) learners in mobile environments. Users can interact with the system by selecting a grammar word and a situational context (e.g., person, place, and activity) as a query, and the system will return a list of relevant sentences corresponding to the selected grammar word and context. These sentences would help users learn appropriate usages of the grammar words in the right context. The user interface represents situational contexts using pictures for ease of context selection. The sentences used for retrieval are gathered from some corpora for Chinese learning and revised by a human expert to improve readability in the corresponding context.
