Measuring lexical accuracy
The categorization of lexical errors in written L2 English
This study seeks to contribute to the dialogue about the creation and application of lexical error annotation schemes for the purpose of studying learner language. It outlines some of the common issues that the creators of such lexical error annotation schemes face on the theoretical level, as well as the less theoretical issues that annotators encounter in practice. The chapter further illustrates the importance of a clean separation of codes that pertain to error description from those that seek to explain errors. In doing so, the study also highlights the importance of the hierarchical structure of error tag sets and how this (previously under-utilized) concept has implications for the comparability of results across learner corpora and their respective annotation schemes.
