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 systemsknowledge and data engineeringdecision supportactive and dynamic systemsdata sharing and warehousingtemporal and spatial database processingintelligent information retrievallearning and adaptationknowledge discovery and data miningartificial lifemodelling and object orientationsoftware re-engineeringco-operativeness, interoperability and software re-usabilityhuman-computer interactionhypertext, hypermedia and multimediadata and knowledge visualizationUnderlying computational techniquessoft computing (including neural nets, fuzzy logic, probabilistic reasoning, and rough set theory)evolutionary computinghybrid computinguncertainty managementagent architectures and systems (including multi-agent scenarios)Platformshigh performance computing systemsdistributed intelligent systemsmobile systemsApplication to specific problem domainsbiomedical systemsgeographical systemssoftware information systemsemerging 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 pa
