Semantic Reconstruction for how many-Questions in LTAG
نویسنده
چکیده
In this paper, we show how to formalize reconstruction effects in an LTAG semantics. We derive a lexical entry and semantic specification for how many, which introduces two quantificational elements. We also show how they interact compositionally with other scopal items, e.g. modal and attitude verbs in a question. The use of an underspecified semantics allows the compact representation of scope ambiguities. We demonstrate how this also enables us to obtain the correct readings in embedded questions.

LTAG Semantics for Questions
This papers presents a compositional semantic analysis of interrogatives clauses in LTAG (Lexicalized Tree Adjoining Grammar) that captures the scopal properties of whand nonwh-quantificational elements. It is shown that the present approach derives the correct semantics for examples claimed to be problematic for LTAG semantic approaches based on the derivation tree. The paper further provides ...
متن کاملRepresenting Focus in LTAG
The paper proposes an LTAG semantic analysis to derive semantic representations for different focus constructions in a uniform way. The proposal is shown via examples of different narrow focus constructions, multiple foci and focus in questions.
متن کاملLatent SVMs for Semantic Role Labeling using LTAG Derivation Trees∗
A phrase structure parse tree for a sentence can be generated by many different Lexicalized Tree-Adjoining Grammar (LTAG) derivation trees. In this paper, we use multiple LTAG derivations as latent features for semantic role labeling (SRL). We hypothesize that positive and negative examples of individual semantic roles can be reliably distinguished by possibly different latent LTAG-based featur...
متن کاملComputing Discourse Semantics: The Predicate-Argument Semantics of Discourse Connectives in D-LTAG
Abstract. D-LTAG is a discourse-level extension of Lexicalized Tree-Adjoining Grammar (LTAG), in which discourse syntax is projected by different types of discourse connectives and discourse interpretation is a product of compositional rules, anaphora resolution, and inference. In this paper, we present a D-LTAG extension of ongoing work on an LTAG syntaxsemantic interface. First, we show how p...
متن کاملGlueTag Linear Logic based Semantics Construction for LTAG
In this paper we review existing appoaches to semantics construction in LTAG (Lexicalised Tree Adjoining Grammar) which are all based on the notion of derivation (tree)s. We argue that derivation structures in LTAG are not appropriate to guide semantic composition, due to a non-isomorphism, in LTAG, between the syntactic operation of adjunction on the one hand, and the semantic operations of co...
