The ABIS workshops have a long tradition. Since the first workshop in 1993 it has been an annual event. Originally a German workshop, it has gradually evolved into an international workshop since 2002. Latest developments in industry and research are presented in plenary sessions, forums, and tutorials. Researchers, Ph.D. students and Web professionals obtain and exchange novel ideas, expertise and feedback on ongoing research before submitting their work to major conferences such as CHI, UMAP, WWW and SIGIR.
