It is a pleasure to invite you to the workshop SLT-1: Semantics of the Long Tail. The workshop is co-located with the IJCNLP 2017 conference, which is organized by The Asian Federation of Natural Language Processing. IJCNLP 2017 will take place in Taipei, Taiwan from the 27th of November to the 1st of December 2017.
The use of language expressions and their meanings follow a Zipfian distribution, featuring a small amount of very frequent observations and a very long tail of low frequent observations. As a result of this, the data we use for learning and testing systems also exhibit overfitting to the head of the distribution. It is thus not surprising that statistical approaches automatically exploit the distributional preference and dominance of the most ‘popular’ interpretations for disambiguation and reference tasks in NLP: most of the test interpretations in a task correspond to the majority interpretations of the training instances. But what about the long–tail cases? How well are systems capable of semantically interpreting less and low-frequent cases? Surprisingly, humans do not experience significant problems determining that a long–tail interpretation applies in a specific text. But how can semantic NLP systems intelligently deal with sparse cases? Little attention has been devoted to how systems should solve interpretation tasks for local and perhaps unknown event and entity instances, which are described in sparse documents, but might not be observed in any training set or knowledge base. Potentially, this would require new representations and deeper processing than the ones that work well on the head, which involves reading between the lines, e.g. textual entailment and robust (common sense) reasoning.
It is the goal of this workshop to bring researchers together to share their experiences and results in dealing with long tail semantics: i.e. interpretation of low-frequent or rare events, entities and relations for which there is little training data. We welcome papers that describe: (error) analyses of semantic tasks with respect to head and long–tail distributions, evaluation of different methods on head and long–tail cases, new methods to interpret long–tail phenomena, and the role of context to prime long–tail cases over head interpretations. We are interested in how knowledge and data can be acquired to counterbalance popular data and interpretations and how to make semantic tasks sustainable over time when the world and the interpretation space changes.
