In linguistics the term diathesis alternation or verb alternation[1] refers to the fact that verbs can be used in different subcategorization frames where they slightly change their semantic meaning. It is a hard problem for theoretical linguistics how to encode constraints on the diathesis alternation of a specific verb to a lexicon. It is also claimed that the manner in which verbs undergo diathesis alternation can be used to identify the semantic class they belong to e.g. in a machine learning task.
