The 18th ACM Symposium on Document Engineering (DocEng 2018) seeks original research papers that focus on the design, implementation, development, management, use and evaluation of advanced systems where document and document collections play a key role. DocEng emphasizes innovative approaches to document engineering technology, use of documents and document collections in real-world applications, novel principles, tools and processes that improve our ability to create, manage, maintain, share, and productively use these. In particular, DocEng 2018 seeks works involving large-scale document engineering applications of industrial relevance.
