INTRODUCTION The aims of this study were to describe the reports of suspected adverse events due to rotavirus vaccines, and assess the reporting sensitivity for intussusception. MATERIAL AND METHODS Descriptive study performed using the reports of suspected adverse events following rotavirus vaccination in infants aged less than 10 months, as registered in the Pharmacovigilance Centre of the ...

The word error rate (WER), commonly used in ASR assessment, measures the cost of restoring the output word sequence to the original input sequence. However, for most CSR applications apart from dictation machines a more meaningful performance measure would be given by the proportion of information communicated. In this article we introduce two new absolute CSR performance measures: MER (match e...

This paper studies the relationship between word error rate (WER) and keyword error rate (KER) in speech transcripts and their effect on the performance of speech analytics applications. Automatic speech recognition (ASR) systems are increasingly used as input for speech analytics, which raises the question of whether WER or KER is the more suitable performance metric for calibrating the ASR sy...

We report on experiments to measure the effect of speech recognition errors and automatic punctuation insertion errors on the performance of information extraction (entity and relation extraction). The outputs of several recognition systems with a range of word error rates (WER), along with punctuation insertion, were fed into a system that extracts entities and relations from the recognized te...

In this paper, we describe the on-going development of a Japanese Broadcast News Transcription system at BBN Technologies. This is a collaboration between BBN and NHK to use automatic speech recognition technology to provide live closed caption for NHK’s TV news programs in Japan. We describe what the NHK Broadcast News Corpus comprises and how we adopted transcription technology developed for ...

CONTEXT In Mexico, where abortion remains largely illegal and clandestine, reliable data on induced abortion and related morbidity are critical for informing policies and programs. The only available national estimate of abortion is for 1990, and demographic and socioeconomic changes since then have likely affected abortion incidence. METHODS This study used official statistics on women treat...

BACKGROUND Adverse drug reactions (ADRs) are a significant cause of morbidity and mortality, with many being identified post-marketing. Improvement in current ADR reporting, including utility of underused or innovative methods, is crucial to improve patient safety and public health. OBJECTIVES To evaluate methods to improve ADR reporting via a systematic literature review. METHODS Data sour...

This paper reports on our recent research in speech recognition by surface electromyography (EMG), which is the technology of recording the electric activation potentials of the human articulatory muscles by surface electrodes in order to recognize speech. This method can be used to create Silent Speech Interfaces, since the EMG signal is available even when no audible signal is transmitted or ...

We propose an alternative evaluation metric to Word Error Rate (WER) for the decision audit task of meeting recordings, which exemplifies how to evaluate speech recognition within a legitimate application context. Using machine learning on an initial seed of human-subject experimental data, our alternative metric handily outperforms WER, which correlates very poorly with human subjects’ success...

OBJECTIVE Breathing rate (BR) can be estimated by extracting respiratory signals from the electrocardiogram (ECG) or photoplethysmogram (PPG). The extracted respiratory signals may be influenced by several technical and physiological factors. In this study, our aim was to determine how technical and physiological factors influence the quality of respiratory signals. APPROACH Using a variety o...
