  1. Lucas Champollion, Aspect, Quantification and Plurality.
    The goal of this dissertation is twofold. First, we aim to identify the source of distributivity in natural language. Our hypothesis is that throughout the grammar, distributivity can be tracked down to a single operator. Two converging lines of reasoning help us identify this operator. One line emerges as a result of generalizing and unifying previously disparate treatments of distributivity in the domain of nominal quantifiers. The other line comes from analyzing the meaning of durative adverbials, with special attention to (...)

  2. Lucas Champollion, A Unified Account of Nominal Distributivity, for -Adverbials, and Measure Phrases.
    In this talk, I first systematize the analogies and complete the picture in some corners. Then, I formally relate the three constructions, and I derive their properties from a single operator. Previous analyses were not designed to account for all three constructions at the same time. Accordingly, I not only assess how well they generalize beyond their intended purpose, but I also evaluate them in their own right. Even so, this analysis improves on previous accounts in several ways. Although I (...)

  3. Lucas Champollion, For-Adverbials Quantify Over Subintervals, Not Subevents.
    The traditional answer is: they must be atelic. But as we will see, this notion is imprecise. We will improve on it, without rejecting it. (Basically we’ll end up with temporally vs. spatially telic.).

  4. Lucas Champollion, Move and Accommodate: A Solution to Haddock's Puzzle.
    What licenses the use of a definite description? The formal and philosophical literature has approached this question in two ways. The uniqueness approach (Frege, 1892; Russell, 1905; Strawson, 1950) holds that we may use a definite determiner only if the property denoted by its complement holds of exactly one individual in some domain: Sentence (1) and (2) can only be true if there is exactly one king of France, and exactly one American governor, respectively. Since this is not the case (...)

  5. Lucas Champollion, Quantification in Event Semantics.
    • Beaver and Condoravdi (2007): NO “In Davidsonian Event Semantics the analysis of quantification is problematic: either quantifiers are treated externally to the event system and quantified in (cf. Landman, 2000), or else the definitions of the quantifiers must be greatly (and non-uniformly) complicated (cf. Krifka, 1989)”.

  6. Lucas Champollion & Aravind K. Joshi, LTAG-Spinal and the Treebank.
    We introduce LTAG-spinal, a novel variant of traditional Lexicalized Tree Adjoining Grammar (LTAG) with desirable linguistic, computational and statistical properties. Unlike in traditional LTAG, subcategorization frames and the argument-adjunct distinction are left underspecified in LTAG-spinal. LTAG-spinal with adjunction constraints is weakly equivalent to LTAG. The LTAG-spinal formalism is used to extract an LTAG-spinal Treebank from the Penn Treebank with Propbank annotation. Based on Propbank annotation, predicate coordination and LTAG adjunction structures are successfully extracted. The LTAG-spinal Treebank makes explicit semantic relations (...)

  7. Williams Hall & Lucas Champollion, Binding Theory in LTAG.
    This paper provides a unification-based implementation of Binding Theory (BT) for the English language in the framework of feature-based lexicalized tree-adjoining grammar (LTAG). The grammar presented here does not actually coindex any noun phrases, it merely outputs a set of constraints on co- and contraindexation that may later be processed by a separate anaphora resolution module. It improves on previous work by implementing the full BT rather than just Condition A. The main technical innovation consists in allowing lists to appear (...)

  8. Lucas Champollion, A Unified Account of Distributivity, for -Adverbials, and Pseudopartitives.
    This paper presents a diagnostic for identifying distributive constructions and shows that it applies to pseudopartitives and for -adverbials. On this basis, a unified account is proposed for the parallels between the constructions involved. This account explains why for -adverbials reject telic predicates (*run to the store for five hours), why pseudopartitives reject count nouns (*five pounds of book ), and why both reject certain measure functions like temperature and speed (*30 of water, *drive for 5 mph). These restrictions all (...)

  10. Lucas Champollion, On the (Ir)Relevance of Psycholinguistics for Anaphora Resolution.
    Psycholinguistic experiments show that pronouns tend to be resolved differently depending on whether they occur in main or subordinate clauses. If a pronoun in a subordinate clause has more than one potential antecedent in the main clause, then the pronoun tends to refer to the antecedent which has a certain thematic role (depending on the verb and on the subordinating conjunction). In contrast, pronouns in main clauses tend to refer back to the subject of the previous main clause, and this (...)

  11. Lucas Champollion, README File for Tblplus Package Author:.
    This is a description of the collection of scripts which I'm submitting as a term project for the CIS530 course, what their purpose is, and how to use them. Note that at the moment I'm writing this, the tool is installed on alpha.nlp.liniac.upenn.edu in the directory /home/champoll/tblplus. It will most likely not run anywhere else at the moment, though it can be adapted easily if the relevant packages (especially fnTBL) are installed. See below fore more details.

  13. Lucas Champollion (2011). Lexicalized Non-Local MCTAG with Dominance Links is NP-Complete. Journal of Logic, Language and Information 20 (3):343-359.
    An NP-hardness proof for non-local Multicomponent Tree Adjoining Grammar (MCTAG) by Rambow and Satta (1st International Workshop on Tree Adjoining Grammers 1992 ), based on Dahlhaus and Warmuth (in J Comput Syst Sci 33:456–472, 1986 ), is extended to some linguistically relevant restrictions of that formalism. It is found that there are NP-hard grammars among non-local MCTAGs even if any or all of the following restrictions are imposed: (i) lexicalization: every tree in the grammar contains a terminal; (ii) dominance links: (...)
