My research focuses on these questions. During my graduate studies and the early part of my career, I focused on the organization of lexical knowledge. In particular, I developed a model that accounts for the way word structure is similar to, but not identical to, the structure of sentences, i.e., words may have the creativity and productivity of syntax, but they can also be idiosyncratic (see Koenig (1999) for a summary). I also showed that this model accounts for the kinds of regularity that languages display between what words mean and the contexts in which they occur (see Davis and Koenig (2000) and Koenig and Davis (2001)).
