This book constitutes the refereed proceedings of the 19th International Conference on Applications of Natural Language to Information Systems, NLDB 2014, held in Montpellier, France, in June 2014. The 13 long papers, 8 short papers, 14 poster papers, and 7 demo papers presented together with 2 invited talks in this volume were carefully reviewed and selected from 73 submissions.

Today, there is an intense interest for bio natural language processing (NLP) creating a need among researchers, academicians, and practitioners for a comprehensive publication of articles in this area. ""Information Retrieval in Biomedicine: Natural Language Processing for Knowledge Integration"" provides relevant theoretical frameworks and the latest empirical research findings in this area according to a linguistic granularity. As a critical mass of advanced knowledge, this book presents original applications, going beyond existing publications while opening up the road for a broader use of NLP in biomedicine.
