2 Jan Šnaider (Zagreb): DErivBase: Derivational Morphology meets Distributional Semantics:
Morphological processing is generally recognized as an important step for many NLP tasks. Most work on computational morphology has focused on inflectional morphology, while derivational morphology, concerned with the formation of new words from existing ones (e.g., read → read+er), has received far less attention. Derivation also introduces a fairly specific semantic shift (+er: agentivization), which makes it very interesting from a lexico-semantic perspective.
In this talk I will present our work on modeling derivational morphology and linking it to distributional semantics. In the first part, I will describe a rule-based framework for inducing so-called derivational families and its application to create a high-coverage German morphological resource called DErivBase. In the second part, I will focus on the lexico-semantic aspects of derivation and present two studies that combine, in different ways, derivational knowledge and distributional semantics. The first study is about "derivational smoothing" of syntax-based vector spaces, in which we use derivational knowledge to improve distributional similarity predictions. The second study goes in the other direction and uses distributional knowledge alongside structural information about derivational rules to perform a "semantic validation" of the DErivBase resource.
