Many Uses, Many Annotations for Large Speech Corpora: Switchboard and TDT as Case Studies

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 additional annotation, all carried out ...

The Tdt-3 Text and Speech Corpus

The TDT-3 Text and Speech Corpus expands on previous phases of Topic Detection and Tracking data collections, by increasing the number of news sources being sampled, by including Mandarin Chinese as well as English news data, and by introducing new forms of topic annotation. In order to satisfy the specific data and annotation requirements of the TDT-3 Evaluation Plan[1], the LDC refined and su...

The existence of spacetime singularities is irrelevant for the irreversible appearance of black holes. However, confirmation of the latter’s unitary dynamics would require the preparation of a coherent superposition of a tremendous number of appropriate “Everett worlds”.

In [1], we present a method to tackle first order ordinary differential equations whose solutions contain Liouvillian functions (LFOODEs), many of them missed by the usual PS-approach. Here, we demonstrate an important result concerning the generality of that method.
