Due to the recent availability of large bodies of text and speech in electronic form, data-based research of all kinds has increased dramatically in areas such as computational linguistics and language engineering (especially corpus-based linguistics), speech, humanities computing, psycho-linguistics, and information retrieval. This series is intended to explore the methodologies and technologies that are emerging as a result of this work. In addition, while each of these disciplines has developed methodologies appropriate to its particular problem area, there is emerging a clearly defined set of technologies and methodologies common to all areas of research involving large quantities of electronic data. The series will be particularly concerned with methodologies and technologies with either actual or potantial applicability to other areas.
