Although paraphrasing and nominalization are established as independent research fields, there exists a close connection between them: nominalizations can be understood as a kind of paraphrase. We believe there is a need to bring together linguists and computer scientists, and we invite unpublished contributions related to issues in these fields with a special emphasis on –though not limited to:
