British and American speakers exhibit different verb number agreement patterns when sentence subjects have collective head nouns. From linguistic and psycholinguistic accounts of how agreement is implemented, three alternative hypotheses can be derived to explain these differences. The hypotheses involve variations in the representation of notional number,… (More)
Recent studies have shown that the presentation of concurrent linguistic context can lead to highly efficient performance in a standard conjunction search task by the induction of an incremental search strategy (Spivey, Tyler, Eberhard, & Tanenhaus, 2001). However, these findings were obtained under anomalously slow speech rate conditions. Accordingly, in… (More)
This paper introduces a novel corpus of natural language dialogues obtained from humans performing a cooperative, remote, search task (CReST) as it occurs naturally in a variety of scenarios (e.g., search and rescue missions in disaster areas). This corpus is unique in that it involves remote collaborations between two interlocutors who each have to perform… (More)
Evidence from recent psycholinguistic experiments suggests that humans resolve reference incrementally in the presence of constraining visual context. In this paper, we present and evaluate a computational model of human reference resolution that directly builds a semantic interpretation of an utterance without the need for a separate syntactic analysis… (More)
Current social robots lack the natural language capacities to be able to interact with humans in natural ways. In this paper, we present results from human experiments intended to isolate spoken interaction types in a search and rescue task and briefly discuss implications for NLP architectures for embodied situated agents.
Evidence from psychology suggests that humans process definite descriptions that refer to objects present in a visual scene incrementally upon hearing them, rather than constructing explicit parse trees after the whole sentence was said, which are then used to determine the referents. In this paper, we describe a real-time distributed robotic architectures… (More)
Situated dialogue corpora are invaluable resources for understanding the complex relationships among language, perception, and action. Accomplishing shared goals in the real world can often only be achieved via dynamic negotiation processes based on the interactants' common ground. In this paper, we investigate ways of systematically capturing structural… (More)
