DESCRIPTION:The assumption that natural language expressions have a single
 \, discrete and clearly identifiable meaning in a given context\, successf
 ully challenged in lexical semantics by the rise of distributional models\
 , nevertheless still underlies much work in computational linguistics\, in
 cluding work based on distributed representations. In this talk I will fir
 st of all present the evidence that convinced us that the assumption that 
 a single interpretation can always be assigned to anaphoric expression is 
 no more than a convenient idealization. I will then discuss recent work on
  the DALI\nproject that aims to develop a new model of interpretation that
  abandons this assumption for the case of anaphoric interpretaton / corefe
 rence. I will present the recently released Phrase Detectives 2.1 corpus\,
  containing around 2 million crowdsourced judgments for more than 100\,000
  markables\, an average of 20 judgments per markable\;\nthe Mention Pair A
 nnotation (MPA) Bayesian inference model developed to aggregate these judg
 ments\; and the results of a preliminary analysis of disagreements in the 
 corpus suggesting that between 10% and 30% of markables in the corpus appe
 ar to be genuinely ambiguous. \n\nJoint work with Jon Chamberlain\, Silviu
  Paun\, Alexandra Uma\, \nJuntao Yu\, Richard Bartle and Udo Kruschwitz
