  • This paper focuses on identifying, extracting and evaluating features related to syntactic complexity of spontaneous spoken responses as part of an effort to expand the current feature set of an automated speech scoring system in order to cover additional aspects considered important in the construct of communicative competence.

  • Spontaneously produced speech text often includes disfluencies which make it difficult to analyze underlying structure. Successful reconstruction of this text would transform these errorful utterances into fluent strings and offer an alternate mechanism for analysis. Our investigation of naturally-occurring spontaneous speaker errors aligned to corrected text with manual semanticosyntactic analysis yields new insight into the syntactic and structural semantic differences between spoken and reconstructed language. ...

  • The paper argues that language change can be explained through the stochasticity observed in real-world natural language use. This thesis is demonstrated by modeling language use through language games played in an evolving population of agents. We show that the artificial languages which the agents spontaneously develop based on self-organisation, do not evolve even if the population is changing.

  • In this paper, we present a chunk based partialparsing system for spontaneous, conversational speech in unrestricted domains. W e show that the chunk parses produced by this parsing system can be usefully applied to the task of reranking Nbest lists from a speech recognizer, using a combination of chunk-based n-gram model scores and chunk coverage scores. The input for the system is Nbest lists generated from speech recognizer lattices.

  • Japanese dependency structure is usually represented by relationships between phrasal units called bunsetsus. One of the biggest problems with dependency structure analysis in spontaneous speech is that clause boundaries are ambiguous. This paper describes a method for detecting the boundaries of quotations and inserted clauses and that for improving the dependency accuracy by applying the detected boundaries to dependency structure analysis.

  • This paper presents a speech understanding component for enabling robust situated human-robot communication. The aim is to gain semantic interpretations of utterances that serve as a basis for multi-modal dialog management also in cases where the recognized word-stream is not grammatically correct. For the understanding process, we designed semantic processable units, which are adapted to the domain of situated communication. Our framework supports the specific characteristics of spontaneous speech used in combination with gestures in a real world scenario. ...

  • This paper describes two methods for detecting word segments and their morphological information in a Japanese spontaneous speech corpus, and describes how to tag a large spontaneous speech corpus accurately by using the two methods. The first method is used to detect any type of word segments. The second method is used when there are several definitions for word segments and their POS categories, and when one type of word segments includes another type of word segments.

  • This paper presents an analysis of analogies based on observations of oatural conversations. People's spontaneous use o f analogies provides Inslg~t into their implicit evaluation procedures for analogies. The treatment here, therefore, reveals aspects of analogical processing that is somewhat more difficult to see in an experimental context. The work involves explicit treatment of the discourse context in which analogy occurs. A major focus here is the formalization of the effects of analogy on discourse development.

  • This paper pinpoints some of the problems faced when a computer text production model (COMMENTATOR) is to produce spontaneous speech, in speech. This paper discusses some of the problems in the light of the computer model of verbal production presented £n Sigurd (1982), Fornell (1983). For experimental purposes a simple speech synthesis device (VOTRAX) has been used. The Problem of producing naturally sounding utterances is also met in text-to-speech systems (see e.g. Carlson & Granstr~m, 1978). ...

  • This paper presents a conditional random field-based approach for identifying speaker-produced disfluencies (i.e. if and where they occur) in spontaneous speech transcripts. We emphasize false start regions, which are often missed in current disfluency identification approaches as they lack lexical or structural similarity to the speech immediately following. We find that combining lexical, syntactic, and language model-related features with the output of a state-of-the-art disfluency identification system improves overall word-level identification of these and other errors. ...

  • Ghrelin, a recently isolated hormone, has been reported to have modulatory effects on smooth muscle contractility. In this study, we investigated the effects of ghrelin on spontaneous contractions in the rat uterus in vitro. Myometrium strips were removed from Wistar rats following decapitation and placed in a jacketed tissue bath.

  • This book presents a fluid mechanics perspective to the dynamics of fronts and vortices and their interaction with waves in geophysical flows. It provides a basic physical background for modeling coherent structures in a geophysical context, and it gives essential information on advanced topics such as spontaneous wave emission and wavemomentum transfer in geophysical flows. Based on a set of lectures by leading specialists, this text is targeted at graduate students, researchers and engineers in geophysics and environmental fluid mechanics. ...

  • Consider the spontaneous emission term describing the contribution of the spontaneous emission to the laser oscillation, which appears as the final term on the right-hand side of the rate equation for the photon density (Eq. (6.21)). Since this term represents the component of the spontaneous emission belonging to the same mode as the laser oscillation (angular frequency !m), it is closely related to the gain for the oscillation mode. Consider a laser of index-guiding type, and let E ¼ E(r) ¼ E(x, y)E(z) be the complex electric field of the oscillation mode. ...
