The Co-Constructed Logic Framework for Understanding Children’s Acts and Their Intentions

With the characteristics of the nonmonotonic logic and defeasible inference, abductive reasoning has been formalized in the field of artificial intelligence, dealing with the local pragmatics (e.g., the resolution of coreference, resolving syntactic and lexical ambiguity and interpreting metonymy and metaphor), recognizing discourse structure and even the speaker’s plan and other issues for natural language understanding. However, Hobbs’ analysis of abduction in recognizing the speaker’s plan was conducted only from the point of view of the verbal information processing that the listener does. To demonstrate the collaborative way that conversational partners working together to understand the logic of human acts and their intentions, this article analyzes the two conversations about the parents questioning their children’s intention for their acts with an abductive reasoning method. The results show that children and parents co-construct segments of discourse with coherence relations across several conversational turns, by that way they build together a simplified framework for understanding the logic of human acts and their intention. For example, when the father and his children co-constructed coherent segments of discourse with the result relation between them, they completed the particular intention understanding at the same time. This research helps in enriching the logic structure of artificial intelligence applications such as visual question answering models and enhancing their reasoning abilities.

A puzzle about narrative progression and causal reasoning

This chapter argues that key to an analysis of narrative progression are aspectual constraints imposed by coherence relations. This argument is based on a discourse like “A cat bit into a mouse while it was wiggling its tail. It was dead”. The fact that it’s infelicitous is remarkable given that the following is fine: “A mouse was dead. A cat bit into it while it was wiggling its tail”. The chapter explains these data in two steps. First, it proposes definitions for the coherence relations, RESULT and EXPLANATION, in which the former, but not the latter, rules out stative arguments. Second, it provides axioms in a default logic which predict the conditions under which these and competing coherence relations are typically inferred. It provides independent evidence for the proposed analysis from discourses involving exclamatives, temporal indexicals, and deverbals. It also considers discourses that challenge the analysis involving perspectival expressions.

Intention and Attention in Image-Text Presentations: A Coherence Approach

In image-text presentations from online discourse, pronouns can refer to entities depicted in images, even if these entities are not otherwise referred to in a text caption. While visual salience may be enough to allow a writer to use a pronoun to refer to a prominent entity in the image, coherence theory suggests that pronoun use is more restricted. Specifically, language users may need an appropriate coherence relation between text and imagery to license and resolve pronouns. To explore this hypothesis and better understand the relationship between image context and text interpretation, we annotated an image-text data set with coherence relations and pronoun information. We find that pronoun use reflects a complex interaction between the content of the pronoun, the grammar of the text, and the relation of text and image.

Interpretation of Korean Null Pronouns in subject and object position: Comparing native and non-native speakers

We report an experiment that investigates how native and non-native Korean speakers’ interpretation of null pronouns in subject and object position is influenced by structural and discourse-level factors. We compare native Korean speakers to L2 Korean learners whose L1, Spanish, only has null pronouns in subject position. We find that native Korean speakers’ interpretation of subject and object null pronouns is guided by structural factors as well as discourse-level coherence relations, with subject nulls being more sensitive to coherence relations than object nulls. In contrast, our results suggest that L2 speakers’ interpretation of null pronouns in Korean is less influenced by coherence relations. Our results support claims that interface phenomena are challenging in L2 acquisition and provide new evidence that this occurs with null pronouns in L2 even when the L1 has null pronouns.

Clause Structure and Illocutionary Force in Medieval Gallo-Romance: Clitic Position in Old Occitan and Early Old French Sentential Coordination

This paper analyzes the position of object and adverbial clitic pronouns in coordinated affirmative verb-first declaratives introduced by e(t) “and” in Old Occitan and early Old French, a context in which clitics are variably preverbal or postverbal. An empirical study reveals that this variation is principled and reflects semantico-discursive properties in the same way in these two related and grammatically similar medieval Gallo-Romance varieties. On a theoretical level, I posit that preverbal clitics occur when conjunction occurs at the TP level, and postverbal clitics occur when conjunction occurs at the CP level, and that the choice of clause structure (TP vs. CP) for second conjunct clauses depends on illocutionary force, which in turn depends on discourse coherence relations and the semantics of verba dicendi (verbs of utterance).

Linguistic Representation and Processing of Copredication

This thesis addresses the lexical and psycholinguistic properties of copredication. In particular, it explores its acceptability, frequency, cross-linguistic and electrophysiological features. It proposes a general parsing bias to account for novel acceptability data, through which Complex-Simple predicate orderings are degraded across distinct nominal types relative to the reverse order. This bias, Incremental Semantic Complexity, states that the parser seeks to process linguistic representations in incremental stages of semantic complexity. English and Italian acceptability data are presented which demonstrate that predicate order preferences are based not on sense dominance but rather sense complexity. Initial evidence is presented indicating that pragmatic factors centred on coherence relations can impact copredication acceptability when such copredications host complex (but not simple) predicates. The real-time processing and electrophysiological properties of copredication are also presented, which serve to replicate and ground the acceptability dynamics presented in the thesis.

Discourse expectations: explaining the implicit causality biases of verbs

This article presents a linguistic account explaining particular mechanisms underlying the generation of expectations at the discourse level. We further develop a linguistic theory – the Empty Slot Theory – explaining the phenomenon of implicit verb causality. According to our proposal, implicit causality (IC) verbs introduce lexically determined slots for causal content of specific types. If the required information is not derivable from the current or preceding context, IC verbs generate the expectation that these slots will be filled in the upcoming discourse. The cognitive mechanism underlying the bias is grounded in the general processing strategy of avoiding accommodation. Empirical evidence for the proposed theory is provided in three continuation experiments in German with comprehensive semantic annotation of the continuations provided by the participants. The reported experiments consistently show that IC bias can be manipulated in systematic ways. Experiment 1 demonstrates important ontological constraints on causal content crucial for our theory. Experiments 2 and 3 show how IC biases can be manipulated in predictable ways by filling the hypothesized slots in the prompt. Experiment 2 illustrates that stimulus-experiencer (experiencer-object) verbs in contrast to causative agent-patient verbs can be manipulated with respect to coherence and coreference by employing adverbial modification. Filling the lexically determined slot of psychological verbs resulted in predictable changes in coherence relations and types of explanations, resulting in the predicted effects on coreference. Experiment 3 extends the empirical investigations to so-called “agent-evocator” verbs. Again, filling the semantic slot as part of the prompt resulted in predictable shifts in coherence relations and explanation types with transparent effects on coreference. The reported experiments shed further light on the close correspondence between coherence and coreference as a hallmark of natural language discourse.
