Training a Prosody-Based Dialog Act Tagger from Unlabeled Data
Here we investigate the use of unlabeled data for training HMM-based dialog act taggers. Three techniques are shown to be effective for bootstrapping a tagger from very small amounts of labeled data.

Media Inequality in Conversation: How People Behave Differently When Interacting With Computers and People
The present study presents a laboratory experiment grounded in the principles of Interpersonal Theory, a psychological approach to interpersonal dynamics. Discourse analyses revealed a key difference in participants ’ behavior – when participants believed they were talking to a person, they showed many more of the kinds of behaviors associated with establishing the interpersonal nature…

National Early Intervention Longitudinal Study (NEILS): Program Director Survey
Directors of programs serving the children and families during their first six months in service complete a mail survey on the characteristics of their programs such as the number and types of clients served, the service providers employed, and where services are provided.

The Robustness of an Almost-Parsing Language Model Given Errorful Training Data
An almost-parsing language model has been developed that provides a framework for tightly integrating multiple knowledge sources. Lexical features and syntactic constraints are integrated into a uniform linguistic structure (called a SuperARV) that is associated with words in the lexicon.

National Early Intervention Longitudinal Study (NEILS): Service Record A
For the study, every six months an early intervention professional completed a questionnaire on received services, including information regarding the transition out of early intervention.
-
National Early Intervention Longitudinal Study (NEILS): Service Record B
An early intervention professional completed a questionnaire on the services provided to each NEILS family, including information regarding the transition out of early intervention. Version A of the service record was used for each six-month period the child was in early intervention until version B of the service record was used.

A Prosody-based Approach to End-of-Utterance Detection That Does Not Require Speech Recognition
In this paper we demonstrate that the improvements due to the prosodic knowledge can be realized largely without alignment information, i.e., without requiring a speech recognizer. A prosodic end-of-utterance detector using only speech/nonspeech detection output is still considerably more accurate and has lower latency than a baseline system based on pause-length thresholding.
