Background

The SynSem research group at the Oslo Center for Advanced Study (CAS) holds a working meeting on design decisions in broad-coverage meaning representation and inference. The meeting will be held from Monday, May 28, to Wednesday, May 30, 2018, at Quality Hotel Leangkollen just outside Oslo. We expect to start the programme on Monday morning after breakfast, i.e. encourage everyone to travel to Oslo on Sunday already; on Wednesday, we will wrap up the meeting at lunch time (say 13:00), so that for most people it should be possible to still catch flights back home that day.

Logistics

Participants are expected to make their own travel arrangements to Oslo and submit transportation receipts for reimbursement upon completion of the meeting. SynSem has earmarked up to EUR 1200 per participant traveling from outside Europe and up to EUR 400 per participant from within Europe; in case you find it impossible to make travel arrangements to Oslo within these limits, please make contact with Dag and Stephan as soon as possible. Accomodation and meals while in Oslo will be covered by SynSem directly.

Please submit your receipts for travel (airfare and airport transfers) for reimbursement on-line no later than mid-June. After Friday, June 15, 2018, it will be impossible to process reimbursement requests.

Programme

We expect to prepare the programme collectively, with presentation (or maybe demonstration) and discussion slots as obvious building blocks. All participants are invited to (though not required) to present on their ongoing work, possibly in collaborating teams. In a first instance, we welcome suggestions for programme elements (of any type, not limited to the above examples), which we will collect incrementally.

High-Level Questions

Some of the central questions we want to engage with are, across different traditions and frameworks

  • What properties should meaning representations have in order to facilitate inference?
  • What kind of information should lexical resources encode to facilitate inference?
  • What kinds of inferential relations are essential for textual inference?
  • How is ambiguity and underspecification factored in, e.g. of scope, word senses, anaphora?
  • Can we have ‘robust inference’? Does the notion even make sense?

Examples of Textual Inference Patterns

From the so-called SICK dataset, used for Task 1 at SemEval 2014:

  • [T] A woman is slicing an onion.
  • [H] An onion is being sliced by a woman. [entailment]
  • [T] There is no woman slicing an onion.
  • [H] A woman is slicing an onion. [contradiction]
  • [T] The woman is dicing a carrot.
  • [H] A woman is slicing an onion. [neutral]

Collected by Cleo Condoravdi:

  • [T] Romano Prodi will meet the US President George Bush in his capacity as the president of the European commission.
  • [H] George Bush is the president of the European commission.

[NYT of April 1, 2005]

  • [T] ABC News revealed today that Ted Koppel, the host of Nightline for 25 years, would leave the network before his contract expired in December.
  • [H] Ted Koppel left ABC before December 2005.
