Challenges for Computer Science and Linguistics LTC 2013 held in Poznan Poland in December

were carefully reviewed and selected from 103 submissions.The papers selected to this volume
belong to various fields of Human Language Technologies and illustrate a large thematic
coverage of the LTC conferences. To make the presentation of the papers possibly transparent we
have structured them into 9 chapters. These are: Speech Processing Morphology Parsing Related
