Recognising realistic emotions and affect in speech: State of the art and lessons learnt from the first challenge

More than a decade has passed since research on automatic recognition of emotion from speech has become a new field of research in line with its 'big brothers' speech and speaker recognition. This article attempts to provide a short overview on where we are today, how we got there and what this can reveal us on where to go next and how we could arrive there. In a first part, we address the basic phenomenon reflecting the last fifteen years, commenting on databases, modelling and annotation, the unit of analysis and prototypicality. We then shift to automatic processing including discussions on features, classification, robustness, evaluation, and implementation and system integration. From there we go to the first comparative challenge on emotion recognition from speech-the INTERSPEECH 2009 Emotion Challenge, organised by (part of) the authors, including the description of the Challenge's database, Sub-Challenges, participants and their approaches, the winners, and the fusion of results to the actual learnt lessons before we finally address the ever-lasting problems and future promising attempts.

Authors', Institutions' and Countries' rankings in regional and urban science : an analysis for nine top international journals from 1991 to 2000

This paper examines the most productive authors, institutions and countries in regional and urban science from 1991 to 2000 using information on published articles (and pages) from a sample of widely recognized journals in this field: ARS, JUE, JRS, IJURR, IRSR, PRS, RSUE, RS and US. We also consider the relation between the country of the institution named in articles and the country in which the journal is published, in order to know if there are a home publication bias in regional and urban science. Analysis was made for the whole decade and by subperiods, this allowed us to make a more dynamic interpretation of the results- El siguiente artículo examina los autores, instituciones y paises más productivos en la ciencia regional y urbana desde 1991 hasta 2000 usando información sobre artículos publicados de una muestra de revistas ampliamente reconocida en este campo: ARS, JUE, JRS, IJURR, IRSR, PRS, RSUE, RS y US. También se analiza la relación existente entre el país de la institución en que el autor desarrolla su investigación y el país de edición de las revistas donde se publican los trabajos con el objetivo de analizar si existe ¿sesgo doméstico¿. El análisis se realiza para toda la década y por subperíodos lo que permite una interpretación dinámica de los resultado
