Various studies have examined the acoustic features in infant directed speech (IDS) and adult directed speech (ADS). However, there are few speech corpora with prominence annotation from multiple listeners or analysis of the acoustic properties of the stressed versus unstressed words, most studies and corpora focusing on syllabic stress. In order to fill this gap, the current study analyzes the...

Most of the anaphoric resolution algorithms developed so far focus on anaphors with NP antecedents, be it inter-sentential or intrasentential. The main focus of this paper is to resolve various other types of anaphors such as discourse deictic anaphors found in computermediated tutorial dialogues on physics. We do this first through a corpus-based study of physics tutoring dialogues. Our approa...

The vast amounts of on-line text now available have led to renewed interest in Information Extraction (IE) systems that analyze unrestricted text, producing a structured representation of selected information from the text. This paper presents a novel approach that uses machine learning to acquire knowledge for some of the higher level IE processing. Wrap-Up is a trainable IE discourse componen...

Biomedical relations are often expressed between entities occurring within the same sentence through syntactic means. However, a significant portion of such relations (in particular, causal relations) are expressed implicitly across sentence boundaries. Inferring these discourse-level relations can be challenging in the absence of syntactic clues. In this paper, we present a study of textual ch...

We report an experiment to evaluate DQGen’s performance in generating three types of distractors for diagnostic multiple-choice cloze (fill-in-theblank) questions to assess children’s reading comprehension processes. Ungrammatical distractors test syntax, nonsensical distractors test semantics, and locally plausible distractors test inter-sentential processing. 27 knowledgeable humans rated can...

Two logics are implicationally equivalent if the axioms and inference rules of each imply the axioms of the other. Characterizing equivalences of various formulations of the sentential calculi is foundational to the study of logic. Using an automated deduction system, I show that Church's P2 sentential calculus can be derived from Łukasiewicz's CN. To prove each of the axioms of P2, the deducti...

This paper describes an advanced spoken language corpus which has been constructed by enhancing an in-car speech database. The corpus has the following characteristic features: (1) Advanced tag: Not only linguistic phenomena tags but also advanced discourse tags such as sentential structures, and utterance intentions, have been provided for the transcribed texts. (2) Large-scale: The sentential...
