Arguments for adjuncts

It is commonly assumed across the language sciences that some semantic participant information is lexically encoded in the representation of verbs and some is not. In this paper, we propose that semantic obligatoriness and verb class specificity are criteria which influence whether semantic information is lexically encoded. We present a comprehensive survey of the English verbal lexicon, a sentence continuation study, and an on-line sentence processing study which confirm that both factors play a role in the lexical encoding of participant information.

SUBLEXICAL MODALITY AND THE STRUCTURE OF LEXICAL SEMANTIC REPRESENTATIONS

This paper argues for a largely unnoted distinction between relational and modal components in the lexical semantics of verbs. Wehypothesize that many verbs encode two kinds of semantic information:a relationship among participants in a situation and a subset ofcircumstances or time indices at which this relationship isevaluated. The latter we term sublexical modality.We show that linking regularities between semantic arguments andsyntactic functions provide corroborating evidence in favor of thissemantic distinction, noting cases in which the semantic groundingof linking through participant-role properties apparently fails. Thissemantic grounding can be preserved, however, once we abstractaway from sublexical modality in lexical semantic representations.Semantically-based linking constraints are insensitive to the sublexicalmodality component of lexical entries and depend only on informationin a predicators “situational core”.

What with? The Anatomy of a (Proto)-Role

This paper describes a comprehensive survey of English verbs that semantically allow or require an Instrument role. It sheds light on the nature of Instrument roles and instrumentality by examining the distribution in semantic space of those verbs. We show first that verbs that semantically require instruments are typically semantically more complex than predicted by current theories of the structural complexity of verb meanings. We also show that verbs that require or allow instruments constrain the end states of situations they describe more than they constrain the agents initial activity. Our survey further suggests that the causal role played by the instrument is more varied than suggested by previous studies and requires the introduction of a new subtype of causal relation, which we dub helping. Finally, our survey demonstrates that verbs that semantically require an instrument cluster together more closely in semantic space and constrain the instruments (causal) role and properties more than verbs that merely allow the presence of an instrument.

Semantic similarity, predictability, and models of sentence processing

The effects of word predictability and shared semantic similarity between a target word and other words that could have taken its place in a sentence on language comprehension are investigated using data from a reading time study, a sentence completion study, and linear mixed-effects regression modeling. We find that processing is facilitated if the different possible words that could occur in a given context are semantically similar to each other, meaning that processing is affected not only by the nature of the words that do occur, but also the relationships between the words that do occur and those that could have occurred. We discuss possible causes of the semantic similarity effect and point to possible limitations of using probability as a model of cognitive effort.

A-definites and the Discourse Status of Implicit Arguments

This paper focuses on the semantics of implicit arguments and compares it with that of explicit indefinites with which they can be truth-conditionally paraphrased. It is shown that once the discourse-potential of expressions is taken into account, the semantics of implicit arguments differs from their indefinite explicit counterparts. They are shown to be semantically identical to a particular kind of non-quantificational NP (a-definites) which are characterized by their inability to serve as antecedents for future reference. A model of this behavior of implicit arguments, it is argued, follows naturally from the underlying assumption of Discourse Representation Theory that semantic representations must include two kinds of information, a set of available discourse markers and a set of predicative conditions. Because implicit arguments satisfy a predicates argument positions without introducing discourse markers into the Discourse Representation Structure of a sentence, they cannot serve as the antecedent of definite pronouns. When they do enter into anaphoric relations it is not through discourse markers equality clauses, but instead is the result of either lexical identification of variables (via semantic detransitivization or meaning postulates) or of an accommodation process which involves bridging and/or factoring interferences.

The Tesserae Project: intertextual analysis of Latin poetry

Tesserae is a web-based tool for automatically detecting allusions in Latin poetry. Although still in the start-up phase, it already is capable of identifying significant numbers of known allusions, as well as similar numbers of allusions previously unnoticed by scholars. In this article, we use the tool to examine allusions to Vergils Aeneid in the first book of Lucans Civil War. Approximately 3,000 lin- guistic parallels returned by the program were compared with a list of known allusions drawn from commentaries. Each was examined individually and graded for its literary significance, in order to benchmark the programs performance. All allusions from the program and commentaries were then pooled in order to examine broad patterns in Lucans allusive techniques which were largely unapproachable without digital methods. Although Lucan draws relatively con- stantly from Vergils generic language in order to maintain the epic idiom, this baseline is punctuated by clusters of pointed allusions, in which Lucan frequently subverts Vergils original meaning. These clusters not only attend the most sig- nificant characters and events but also play a role in structuring scene transitions. Work is under way to incorporate the ability to match on word meaning, phrase context, as well as metrical and phonological features into future versions of the program.

Intertextuality in the digital age

This paper describes a new digital approach to intertextual study involving the creation of a free online tool for the automatic detection of parallel phrases. A test comparison of Vergil’s Aeneid and Lucan’s Civil War shows that the tool can identify a substantial number of meaningful intertexts, both previously recorded and unrecorded. Analysis of these results demonstrates how automatic detection can provide more comprehensive and accessible perspectives on intertextuality as an aggregate phenomenon. Identification of the language features necessary to detect intertexts also provides a path toward improved automatic detection and more precise definitions of intertextuality.

When is schematic participant information encoded? Evidence from eye-monitoring

Abstract Two eye-monitoring studies examined when unexpressed schematic participant information specified by verbs is used during sentence processing. Experiment 1 compared the processing of sentences with passive and intransitive verbs hypothesized to introduce or not introduce, respectively, an agent when their main clauses were preceded by either agent-dependent rationale clauses or adverbial clause controls. While there were no differences in the processing of passive clauses following rationale and control clauses, intransitive verb clauses elicited anomaly effects following agent-dependent rationale clauses. To determine whether the source of this immediately available schematic participant information is lexically specified or instead derived solely from conceptual sources associated with verbs, Experiment 2 compared the processing of clauses with passive and middle verbs following rationale clauses (e.g., To raise money for the charity , the vase was/had sold quickly …). Although both passive and middle verb forms denote situations that logically require an agent, middle verbs, which by hypothesis do not lexically specify an agent, elicited longer processing times than passive verbs in measures of early processing. These results demonstrate that participants access and interpret lexically encoded schematic participant information in the process of recognizing a verb.

French Body-Parts and the Semantics of Binding

This paper discusses the grammar of the French Inalienable Possession Construction (IPC). It is argued that the IPC involves an unexpressed reflexive anaphor. The antecedent of this reflexive anaphor must satisfy a semantic condition which requires consideration of thematic lexical entailments. The model-theoretic nature of this constraint suggests that the range of semantic information relevant to syntactic processes goes beyond the formal configuration of semantic metalanguages. It also shows that the semantic conditions which anaphors can impose on their antecedents are not restricted to thematic ranking or center of perspective restrictions. An analysis of the construction within Head-driven Phrase-Structure Grammar is provided.

Lexical Encoding of Event Participant Information

The typical understanding of a short passive sentence like The ship was sunk is that it was sunk by someone. We investigated whether unexpressed agent information is introduced via semantic argument information associated with the lexical representations of verbs, or instead via conceptually derived inferences. We demonstrate, in self-paced reading and eye-monitoring studies, that implicit agents are derived from lexical rather than conceptual sources and that verb argument structure information is accessed as soon as a verb is recognized.
