Abstract
Semantic Compositionality, or rather the lack of it, has received some attention in recent years because of the impact it has on semantic interpretation and thus any NLP system that relies on this. I will survey previous methods for detecting compositionality and describe the various approaches to evaluation. I will discuss the extent to which the techniques for both extraction and evaluation are actually addressing compositionality rather than institutionalisation. I will also describe some of the work done by myself and colleagues at Sussex University in this area and compare results on datasets used by others in the field.
