The ICDM 13 Data Mining in Biomedical Informatics and Healthcare workshop aims to provide a forum for data miners, informaticists and clinical researchers to share information on their latest investigations in applying data mining techniques to biomedical and healthcare data. The broader context of the workshop comprehends artificial intelligence, information retrieval, machine learning, and natural language processing. Submissions are invited to address the need for developing new methods to mine, summarize and integrate the huge volume and diverse modalities of the structured and unstructured biomedical and healthcare data that can potentially lead to significant advances in the field.
