In this chapter, I will try to give an idea of what semantic underspecification is, what it has been good for, and what the perspective for future application are. I will start with the inspection of specific phenomena and techniques which are usually associated with the notion of underspecification (in Section 1 and 2, respectively). In Sect. 3, I will try to indicate the main motivations for using underspecification techniques. Then, I will point out one important use of the concept in some detail, i.e., direct reasoning with incomplete semantic information, discussing first the appropriate truth-conditional basis (Sect. 4), and second perspectives on efficient reasonig systems (Sect. 5). I will conclude with some remarks about the general status of the semantic underspecification concept, in Sect. 6.Fri Dec 14 02:44:22 CET 2007Events and More in Dynamic SemanticsOrder-Independence and Underspecification1995underspecification Fri Dec 14 02:43:03 CET 2007Proceedings of the 28th conference on Association for Computational Linguistics31--38Structural disambiguation with constraint propagation1990constraint_programming underspecification Fri Dec 14 02:41:42 CET 2007Proc. LLC8Constraint Programming Technology in Computational Linguistics1999underspecification constraint_programming DG Constraint programming is a programming paradigm that was originally invented in computer science to deal with hard combinatorial problems. Recently, constraint programming has evolved into a technology which permits to solve hard industrial scheduling and optimization problems. We argue that existing constraint programming technology can be useful for applications in natural language processing. Some problems whose treatment with traditional methods requires great care to avoid combinatoric explosion of (potential) readings seem to be solvable in an efficient and elegant manner using constraint programming. We illustrate our claim by two recent examples, one from the area of underspecified semantics and one from parsing.Fri Dec 14 02:41:17 CET 2007Proc. 12th Amsterdam ColloquiumFactoring Predicate Argument and Scope Semantics: Underspecified Semantics with {LTAG}1999TAG underspecification This paper proposes a compositional semantics for lexicalized tree-adjoining grammar (LTAG)...Fri Dec 14 02:41:12 CET 2007Tilburg, The NetherlandsProc. {IWCS}-3131-145Compositional Semantics with Lexicalized Tree-Adjoining Grammar ({LTAG}): How Much Underspecification is Necessary?1999TAG underspecification In this paper we address the following question: How can one construct a semantic representation monotonically yet allow for possible nonmonotonicity in the syntactic composition?...Fri Dec 14 02:39:21 CET 2007DublinAvailable at \myurl{http://www.compapp.dcu.ie/CA\_Working\_Papers/wp96.html}F-Structures, {QLF}s and {UDRS}s1996underspecification QLF Fri Dec 14 02:38:29 CET 2007Journal of Semantics37-82Wh-questions in Underspecified Minimal Recursion Semantics151998MRS HPSG underspecification In this paper, I present Underspecified Minimal Recursion Semantics (UMRS), a representation language that represents structural ambiguities in terms of underspecification. It is argued that this kind of approach allows for transparent semantic representations and a straightforward syntax-semantics interface. UMRS is a semantic metalanguage, whose expressions describe expressions of an object language and (possibly underspecified) dependences between them. The potential of UMRS will be illustrated by employing it as the semantic component of an HPSG description of wh-questions.Fri Dec 14 02:38:26 CET 2007MadridProceedings of the ACL 1997Also in \myurl{http://xxx.lanl.gov/abs/cmp-lg/9706028}386-393Efficient Construction of Underspecified Semantics under Massive Ambiguity1997underspecification Fri Dec 14 02:37:40 CET 2007DraftMinimal Recursion Semantics: an Introduction1999MRS HPSG underspecification We describe minimal recursion semantics (MRS), a framework for computational semantics which simplifies the design of algorithms. We have integrated an implementation of MRS with an HPSG grammar for both parsing and generation that enables a simple formulation of the grammatical constraints on lexical and phrasal semantics. We discuss why, in general, a semantic representation with minimal structure is desirable and illustrate how a descriptively adequate representation with a nonrecursive structure may be achieved.Fri Dec 14 02:37:39 CET 2007Stanford, CAMinimal Recursion Semantics: an Introduction1997MRS HPSG underspecification We describe minimal recursion semantics (MRS), a framework for computational semantics which simplifies the design of algorithms.
