The organizers of the SemEval-2018 – Task 9 are pleased to announce the shared task on Hypernym Discovery.
Hypernymy, i.e. the capability for generalization, lies at the core of human cognition. It is not surprising, therefore, that identifying hypernymic relations (i.e., is-a relations) has been pursued in NLP for over two decades. This task contributes in fact to the improvement of Question Answering, Textual Entailment and Semantic Search systems. In addition, hypernymic relations are the backbone of almost any ontology, semantic network and taxonomy, being therefore fundamental for downstream tasks, such as web retrieval, website navigation or records management.
In previous editions of SemEval, the identification of hypernymic relations from text corpora has been evaluated within the broader task of Taxonomy Evaluation. Most of other attempts have approached hypernymic relations through the task of Hypernym Detection, i.e. the binary task consisting of, given a pair of words, deciding whether a hypernymic relation holds between them or not. This experimental setting has already led to criticisms regarding its alleged oversimplification. Inspired by recent work, we propose therefore to reformulate the problem as Hypernym Discovery, i.e. given the search space of a domain’s vocabulary, and an input concept, discover its best (set of) hypernyms.
Colleagues are invited to participate by proposing a system for hypernym discovery by the evaluation deadline, on the 29th of January 2018 (test data will be released on the 8th of January). Training Data has just been released and it is accessible in the task’s website. Short papers describing the systems and their evaluation results must be submitted by the 26th of February 2018. All papers that meet the formal review criteria will be published in the workshop proceedings.
