Abstract
his paper describes the USAAR-WLV taxonomy induction system that participated in the
Taxonomy Extraction Evaluation task of SemEval-2015. We extend prior work on using
vector space word embedding models for hypernym-hyponym extraction by simplifying the
means to extract a projection matrix that transforms any hyponym to its hypernym. This is
done by making use of function words, which are usually overlooked in vector space
approaches to NLP. Our system performs best in the chemical domain and has achieved
competitive results in the overall evaluations.
