Conference Paper
Full-text available
Monolingual alignment is frequently required for natural language tasks that involve similar or comparable sentences. We present a new model for monolingual alignment in which the score of an alignment decomposes over both the set of aligned phrases as well as a set of aligned dependency arcs. Optimal alignments under this scoring function are deco...
Conference Paper
Full-text available
We present original fieldwork data as evidence that the Tagalog reportative evidential daw projects, like e.g. presuppositions and conventional implicatures (CIs), in the sense that daw can carry an implication that is immune to entailment-modifying operators. Previous work has purported that evidentials in other languages can project, but after ex...
Article
Full-text available
So-called ‘dynamic’ semantic theories such as Kamp’s discourse representation theory and Heim’s file change semantics account for such phenomena as crosssentential anaphora, donkey anaphora, and the novelty condition on indefinites, but compare unfavorably with Montague semantics in some important respects (clarity and simplicity of mathematical fo...
Article
Full-text available
This paper reports on progress towards de-veloping the first broad coverage English surface realizer for Combinatory Catego-rial Grammar (CCG). The paper provides initial automatic evaluation results which are roughly comparable to those reported with other formalisms when using a (non-blind) grammar derived from the develop-ment section of the CCG...
Article
Full-text available
Supplements have often been characterized as inert with respect to other content. But under closer scrutiny, the data shows that supplements can take scope and participate in anaphoric links, undermining multidimensional accounts of them. I argue that the core empirical facts pertaining to supplements, including projection, can in many cases be acc...

Full-text available
A syntax-semantics interface for supplement constructions in a unidimensional framework, requiring only two new lexical entries: one for supplements in utterance-medial position and a second for utterance-final position. The account captures supplement projection, scope, anaphora between supplements and other content, and supplement (non)deniabilit...
Research
Full-text available
Reexamines the nature of supplements, calling into question their supposed scopelesness and not-at-issueness. Gives a formal account that allows them to scope and participate in anaphoric links, but only requires a single extra lexical entry.
Conference Paper
Full-text available
We present a compositional, dynamic categorial grammar for discourse analysis that captures the core insights of dynamic semantics: indefinites do not quantify but introduce discourse referents; definites are anaphoric to previously-mentioned discourse referents; discourse referents have their 'lifespan' limited by certain operators. The categorial...
Conference Paper
Full-text available
The accessibility constraints imposed on anaphora by dynamic theories of discourse are too strong because they rule out many perfectly felicitous cases. Several attempts have been made by previous authors to rectify this situation using various tactics. This paper proposes a more viable approach that involves replacing Heim’s notion of familiarity...
Conference Paper
Full-text available
We present a method of creating disjunctive logical forms (DLFs) from aligned sentences for grammar-based paraphrase generation us-ing the OpenCCG broad coverage surface realizer. The method takes as input word-level alignments of two sentences that are para-phrases and projects these alignments onto the logical forms that result from automatically...
Article
Full-text available
We present a dynamic semantic theory that synthesizes as-pects of de Groote's (2006) continuation-based dynamics and Pollard's (2008a) hyperintensional semantics. In this theory, we rely on an enriched notion of discourse context inspired by the work of Heim (1983a,b) and Roberts (1996, 2004). We show how to use this enriched context to im-prove on...
Article
Full-text available
Corpus conversion and grammar extraction have traditionally been portrayed as tasks that are performed once and never again revisited (Burke et al., 2004). We report the successful implementation of an approach to these tasks that facilitates the improvement of grammar engineering as an evolving process. Taking the standard version of the CCGbank (...

Full-text available
This paper describes an XML annotation scheme for English Language Learner (ELL) spelling errors in learner corpora which can be used to create standardized, annotated ELL er- ror corpora for use by researchers who are de- veloping spelling correction tools for ELLs. We also provide an error taxonomy (with ex- amples of each error type) upon which...

This paper sketches an account of the behavior of French pronominal clitics in CVG, a proof-theoretic categorial grammar formalism. The approach shown here differs from most categorial analyses of French clitics in that it treats clitics as noun phrases rather than as functions that operate on under-saturated verb phrases. Basic French cliticizatio...
