Deverbal zero-nominalization and verb classes: Insights from a database

We investigate deverbal zero-derived nominals in English (e.g., to walk > a walk) from the perspective of the lexical semantics of their base verbs and the interpretations they may receive (e.g., event, result state, product, agent). By acknowledging that, in the absence of an overt affix, the meaning of zero-nominals is highly dependent on that of the base, the ultimate goal of this study is to identify possible meaning regularities that these nominals may display in relation to the different semantic verb classes. We report on a newly created database of 1,000 zero-derived nominals, which have been collected for various semantic verb classes. We test previous generalizations made in the literature in comparison with suffix-based nominals and in relation to the ontological type of the base verb. While these generalizations may intuitively hold, we find intriguing challenges that bring zero-derived nominals closer to suffix-based nominals than previously claimed.

Event/Result in Morphology

This article revisits Grimshaw's (1990) tripartition of nominalization, which introduced an important correlation between particular types of nominalization and the readings associated with these nominal forms, Event and Referential. The article discusses criteria that may be used to distinguish between the two readings and the limitations of these criteria. It further offers a selective discussion of how different approaches to nominalization implement Event and Referential readings.

Nominalization: General Overview and Theoretical Issues

Nominalization refers both to the process by which complex nouns are created and to the complex nouns that are derived by that process. Nominalizations common in the languages of the world include event/result nouns, personal or participant nouns (agent, patient, location, etc.), as well as collectives and abstracts. It is common for nominalizations to be highly polysemous. Theoretical issues concerning nominalization typically stem from the question of how to account for this pervasive polysemy. Within generative grammar, both syntactic and lexicalist approaches have been proposed. The issue of polysemy in nominalization has also been of interest within cognitive and functional frameworks. The article considers, finally, the extent to which nominalization is subject to competition and blocking.

Cognitive Grammar and English nominalization: Event/result nominals and gerundives

This article develops an analysis of event/result nominals and gerundives from a Cognitive Grammar perspective. By reviewing the previous research, we first point out that these phenomena are much more flexible than the extant research claims. Moreover, widely accepted generalizations concerning the phenomena are, at best, only partially true. We demonstrate that the said flexibility is ascribed to two different types of construals: [1] mass-like construal accompanied by reification and [2] zone-activation or metonymic shift. Event nominals arise, without respect to the types of the nominal affixes, when the relationship profiled by a verb takes an internal perspective. Result nominals arise through zone activation or metonymic shift in addition to the reification of the verbal base. Several grounding strategies apply to both event and result nominals, thereby yielding different realizations of instances such as (in)definite and possessive. We show that our analysis can be systematically extended to gerundives, which permit limited grounding methods. We also demonstrate that V-to-N converted event nominals are accounted for unproblematically in our analysis because the rise of event nominals does not rely on the nominalizing affixes.

Empirical Methods for the Study of Denotation in Nominalizations in Spanish

This article deals with deverbal nominalizations in Spanish; concretely, we focus on the denotative distinction between event and result nominalizations. The goals of this work is twofold: first, to detect the most relevant features for this denotative distinction; and, second, to build an automatic classification system of deverbal nominalizations according to their denotation. We have based our study on theoretical hypotheses dealing with this semantic distinction and we have analyzed them empirically by means of Machine Learning techniques which are the basis of the ADN-Classifier. This is the first tool that aims to automatically classify deverbal nominalizations in event, result, or underspecified denotation types in Spanish. The ADN-Classifier has helped us to quantitatively evaluate the validity of our claims regarding deverbal nominalizations. We set up a series of experiments in order to test the ADN-Classifier with different models and in different realistic scenarios depending on the knowledge resources and natural language processors available. The ADN-Classifier achieved good results (87.20% accuracy).

Adding semantic roles to the Chinese Treebank

We report work on adding semantic role labels to the Chinese Treebank, a corpus already annotated with phrase structures. The work involves locating all verbs and their nominalizations in the corpus, and semi-automatically adding semantic role labels to their arguments, which are constituents in a parse tree. Although the same procedure is followed, different issues arise in the annotation of verbs and nominalized predicates. For verbs, identifying their arguments is generally straightforward given their syntactic structure in the Chinese Treebank as they tend to occupy well-defined syntactic positions. Our discussion focuses on the syntactic variations in the realization of the arguments as well as our approach to annotating dislocated and discontinuous arguments. In comparison, identifying the arguments for nominalized predicates is more challenging and we discuss criteria and procedures for distinguishing arguments from non-arguments. In particular we focus on the role of support verbs as well as the relevance of event/result distinctions in the annotation of the predicate-argument structure of nominalized predicates. We also present our approach to taking advantage of the syntactic structure in the Chinese Treebank to bootstrap the predicate-argument structure annotation of verbs. Finally, we discuss the creation of a lexical database of frame files and its role in guiding predicate-argument annotation. Procedures for ensuring annotation consistency and inter-annotator agreement evaluation results are also presented.
