Knowledge and Information Systems (KAIS) provides an international forum for researchers and professionals to share their knowledge and report new advances on all topics related to knowledge systems and advanced information systems.  This monthly peer-reviewed archival journal publishes state-of-the-art research reports on emerging topics in KAIS, reviews of important techniques in related areas, and application papers of interest to a general readership.  The journal focuses on knowledge systems and advanced information systems, including their theoretical foundations, infrastructure and enabling technologies.  We solicit submissions of original research, and experience and vision papers that address this theme.  Suggested topics include, but are not limited to, the following areas: Knowledge and information processing: theory, techniques and systems knowledge and data engineering decision support active and dynamic systems data sharing and warehousing temporal and spatial database processing intelligent information retrieval learning and adaptation knowledge discovery and data mining artificial life modelling and object orientation software re-engineering co-operativeness, interoperability and software re-usability human-computer interaction hypertext, hypermedia and multimedia data and knowledge visualization Underlying computational techniques soft computing (including neural nets, fuzzy logic, probabilistic reasoning, and rough set theory) evolutionary computing hybrid computing uncertainty management agent architectures and systems (including multi-agent scenarios) Platforms high performance computing systems distributed intelligent systems mobile systems Application to specific problem domains biomedical systems geographical systems software information systems emerging applications (such as Internet technologies and digital libraries) We publish critical review papers to discuss the state of the art in particular areas, as well as state-of-the-art research reports.  Accepted papers are grouped for publication so that individual issues focus on a small number of theme areas.  In addition to archival papers, the journal also publishes significant on-going research in the form of Short Papers (limited to 3000 words), and very short papers on "visions and directions" (no more than 1000 words, excluding bibliography).  We conduct reviews in a timely fashion and inform authors of decisions with a target turnaround time of 3 months. Selected papers from relevant conferences are welcome. Good papers with high quality reviews can be accepted after the expansion and revision is verified by an Associate Editor of the Editorial Board. Conference organizers are invited to contact the Editor-in-Chief kais@cs.uvm.edu for further information.
