Expert Panel Review of OERL’s Instructional Utility
The OERL team has adapted and integrated several evaluation methodologies to examine patterns of usage, customer satisfaction, and the instructional utility of the site. These methods include surveys of target audiences, usability testing, and an expert panel review. This chapter presents the results from the expert review.

Introduction to special issue on sensing-based interaction
Sensing-based interaction is at the core of, or synonymous with, many emerging or fast developing areas of human-computer interaction research, including pervasive, ubiquitous or context aware computing, intelligent environments, augmented reality interfaces, and tangible interfaces.

SRI’s 2004 NIST Speaker Recognition Evaluation System
This paper describes our recent efforts in exploring longer-range features and their statistical modeling techniques for speaker recognition. In particular, we describe a system that uses discriminant features from cepstral coefficients, and systems that use discriminant models from word n-grams and syllable-based NERF n-grams.

Structural Metadata Research in the EARS Program
In this paper we provide a brief overview of research on structural metadata extraction in the DARPA EARS rich transcription program. Tasks include detection of sentence boundaries, filler words, and disfluencies.

Automatic Dialog Act Segmentation and Classification in Multiparty Meetings
We explore the two related tasks of dialog act (DA) segmentation and DA classification for speech from the ICSI Meeting Corpus. We employ simple lexical and prosodic knowledge sources, and compare results for human-transcribed versus automatically recognized words.

Participatory, Example-Based Data Modeling In Padi (Padi Technical Report 4)
We describe a Web-based tool for modeling that creates and manipulates a simple data model without representing it in UML, while promoting collaboration and the use of examples to compare and validate the model.

Improved Phonetic Speaker Recognition Using Lattice Decoding
In this paper, we present results on the Switchboard-2 corpus, where we compare 1-best phone decodings versus lattice phone decodings for the purposes of performing phonetic speaker recognition.

Reference-Free Objective Quality Metrics for MPEG-Coded Video
In this paper, we propose a reference-free video quality metric for MPEG coded videos. It predicts subjective quality ratings using both reference-free MPEG artifact measures and MPEG system parameters (known or estimated).

Fostering Collaboration with a Semantic Index over Textual Contributions
We are exploring new approaches to facilitating effective collaboration that remove or reduce common barriers and that exploit opportunities to encourage more effective collaboration, including transcending the cognitive biases of the participants.
