This paper describes the creation and content two corpora, TDT-2 and TDT-3, created for the DARPA sponsored Topic Detection and Tracking project. The research goal in the TDT program is to create the core technology of a news understanding system that can process multilingual news content categorizing individual stories according to the topic(s) they(More)
The paper describes the design, collection, transcription and analysis of 200 hours of HKUST Mandarin Telephone Speech Corpus (HKUST/MTS) from over 2100 Mandarin speakers in mainland China under the DARPA EARS framework. The corpus includes speech data, transcriptions and speaker demographic information. The speech data include 1206 ten-minute natural(More)
Coelenterate neurones produce peptides containing an Arg-Phe-NH2(RF-amide)-like carboxyterminus. RF-amide-like peptides are located in neuronal dense-cored vesicles, indicating that they are released by exocytosis and that they might function as neurotransmitters or neurohormones. Using a radioimmunoassay for the sequence RF-amide, 3 peptides were isolated(More)
This paper describes new language resources designed to support research in speaker recognition. It begins with a brief overview of collections protocols, motivates the shift from the Switchboard protocol to the Mixer protocol, summarizes yields from the earliest phase of Mixer collection and then describes more recent phases, yields and expected yields and(More)
This paper discusses the challenges that arise when large speech corpora receive an ever-broadening range of diverse and distinct annotations. Two case studies of this process are presented: the Switchboard Corpus of telephone conversations and the TDT2 corpus of broadcast news. Switchboard has undergone two independent transcriptions and various types of(More)
A radioimmunoassay has been developed for peptides containing the carboxyl-terminal sequence Arg-Phe-NH2 (RFamide). Using this radioimmunoassay and applying cation-exchange chromatography and HPLC, we have isolated an RFamide peptide from acetic acid extracts of the sea anemone Anthopleura elegantissima. Three different methods established that the(More)
We describe a simple assay for small amounts of protein that is insensitive to sodium dodecyl sulfate (SDS) or many common interfering substances including Tris and reducing sugars. For this reason, it is particularly useful in the analysis of protein content of samples prior to SDS electrophoresis. The assay consists of the following steps: (i) absorption(More)
