In common language and ontology.Knowledge Management: Strategies, Processes, Metrics and ToolsKnowledge Management: Within and Across Corporations and AgenciesStrategiese.g., Management Plans; Policies;Data sharing vs. PrivacyProcessese.g., best practicesMetricse.g., web usageToolse.g., Semantic WebKnowledge Management ArchitectureKnowledge Creation and Acquisition ManagerKnowledge RepresentationManagerKnowledge ManipulationManagerKnowledge Dissemination and SharingManagerOpen System Concept for Knowledge Management Architecture-When in need of a component:-Use a COTS one if available-Build one with a standard API and share it, reusing design from other components-Build a domain-specific one and share it-Allow component integrators and users to tailor or configure applications from components:-Compose systems from components-Tailor a component in unanticipated ways-Tailor a component in anticipated ways-Build software that can interoperate with other softwareKnowledge Exchange & AnnotationEngine (KEAN)-Resides on any web-accessible knowledge base (any intranet, www)-Increases incentive to share information-Author gets positive and negative feedback about information that is submitted-Feedback system - no more publishing documents that disappear into the ether-Prestige - top rated document views-Quality filters steer user towards best information-Domain specific instances of KEAN are created-Works with Java enabled browserSoftware Components“The KeanBeans Component Framework”-Provides the infrastructure for the creation of an open system for KMA -A pallet of JavaBeans components that facilitate the creation of web tracklets by power users, component integrators and developers-Uses industry standards to prompt reuse. Examples: JavaBeans, enterprise JavaBeans(EJB), infobus and Java Foundation Classes(JFC)The Three Versions of KEAN Architecture-Version 1 “beta version”-No reuse-Two-tiered -Stored procedures-Version 2 “newest version”-GUI reuse via JavaBeans-Two-tiered -JDBC access to database-Version 3 “final version”-Logic reuse via Enterprise JavaBeans (EJB)-Three-tiered-CORBA access to objectsStructure of Version 1 - Beta Version of KEAN “Thin http” client•Html•JavaScript•AppletsStored Procedures(PL/SQL)Database tier•ORACLEORACLE WEBSERVERStructure of Version 2 “Thick” clientDatabase
