In this paper we present a fully lexicalized grammar formalism as a particularly attractive framework for the specification of natural language grammars. We discuss in detail Feature-based, Lexicalized Tree Adjoining Grammars (FB-LTAGs), a representative of the class of lexicalized grammars. We illustrate the advantages of lexicalized grammars in various contexts of natural language processing,...

Languages differ in how they package the components of an event into words to form sentences. For example, while some languages typically encode the manner of motion in the verb (e.g., running), others more often use verbs that encode the path (e.g., ascending). Prior research has demonstrated that children and adults have lexicalization biases; that is, they assume that novel motion verbs will...

In this paper, we attempt to answer the vexing question why it should be the case that only certain types of noun meanings exhibit a mass/count variation in the lexicalization of their semantic properties, while others do not. This question has so far remained unanswered, or been set aside. We will do so by focusing on the role of contextsensitivity (already highlighted in recent theories of th...

We use children's noun learning as a probe into the nature of their syntactic prediction mechanism and statistical knowledge on which that is based. focus verb-based predictions, considering two possibilities: predictions might rely distributional about specific verbs–i.e. they be lexicalized–or general to all verbs. In an intermodal preferential looking experiment, we establish are lexicalized...

We study the impact of big models (in terms of the degree of lexicalization) and big data (in terms of the training corpus size) on dependency grammar induction. We experimented with L-DMV, a lexicalized version of Dependency Model with Valence (Klein and Manning, 2004) and L-NDMV, our lexicalized extension of the Neural Dependency Model with Valence (Jiang et al., 2016). We find that L-DMV onl...

The packaging of meaning in verbs varies widely across languages since are free to encode different aspects an event. At the same time, tend display recurrent preferences lexicalization, e.g. verb-framing vs. satellite-framing motion. It has been noted, however, that lexicalization patterns motion not carried over domain vision, gaze trajectory (‘visual path’) is coded outside main verb even ve...

In spite of its potential for bidirectionality, Extensible Dependency Grammar (XDG) has so far been used almost exclusively for parsing. This paper represents one of the first steps towards an XDG-based integrated generation architecture by tackling what is arguably the most basic among generation tasks: lexicalization. Herein we present a constraint-based account of disjunction in lexicalizati...
