DESCRIPTION:At this session of the NLIP Reading Group we'll be discussing 
 (part of) the following paper:\n\nAlexander Koller\, Stefan Thater\, and M
 anfred Pinkal. "Scope underspecification with tree descriptions: Theory an
 d practice":http://www.coli.uni-saarland.de/~koller/showpaper.php?id=choru
 s-08. To appear in Siekmann\, J.\, Crocker\, M. (eds.)\, Resource Adaptive
  Cognitive Processes\, Berlin\, Springer.\n\n*Abstract:*\nIn this paper\, 
 we outline the results of the CHORUS project on the topic of semantic unde
 rspecification\, along two major lines of research: We review a series of 
 solvers for dominance constraints and dominance graphs\, two closely relat
 ed underspecification formalisms developed in CHORUS\, and present researc
 h results concerned with semantic construction and the development of wide
 -coverage underspecification methods that can be applied on "real world" c
 orpus data.\n\n*Reading Notes*\nOver the last ten-or-so years\, Koller & T
 hater have published a series of papers on the theoretical and computation
 al properties of semantic representations like MRS w.r.t. the problem of s
 cope underspecification.\n\nThis paper makes for a really nice read for a 
 general-interest NLP audience\, because it summarizes this work concisely.
  The paper is 27 book-sized pages\, if you want to skip stuff\, Richard su
 ggests skipping the following sections: Section 1 (intro)\, Section 2.3 (t
 heoretic subtlety)\, Sections 3.1/3.2 (historical)\, Section 4.1 (if you a
 lready know MRS)\, Section 6 (recap).
