Knowledge management problem • Introduce KM in departments • What is KM problem at department? • Many tools and techniques available • How to find and select them? • How to combine them? Problem tasks to achieve enablers KM plan
Goals of KM tasks • Identify needed knowledge needed(K) • Search needed knowledge located(K) • Acquire or develop knowledge acquired(K) • Store knowledge stored(K) • Distribute and share knowledge available_at_end_user(K) • Control knowledge quality(K) • Foster use of knowledge exploited(K)

From the final user viewpoint • Browse and shop • Browsing an ontology • Browsing a library • Search for components • Problem oriented • Goal oriented • Enablers oriented • Manipulate components
Order set of enablers along various criteria Notification of sub goals of a KM task Diagnosis KM problem: culprit task Generate (partial) order plan based on current selection of enablers Generate possible completions of KM plan that satisfy criteria Check consistency of selected set of enablers Suggest alternative enablers for same KM goal Other functionalities
Implementation issues • Programming language: Java2 Platform • Modeling language: UPML • Modeling editor: Protege2000 • User interface • Java Applet • HTML + Javascript
Automating access to information resources in molecular biology • Molecular biologist seek to exchange • Primary data • Software tools that can analyze their data, • Results of processing their data with such tools, • Experience that they have learned from applying the tools.
Molecular biologists have to • Analyze large amounts of data by standard algorithms • Predict 3D structure of molecules given DNA sequence • Choosing the right algorithm is hard • Each algorithm has own characteristics (form) • Not possible to easily try out all
Objective • Assemble library of algorithms for 3D structure • Take away (software engineering) burden to work with algorithms • Capture feedback of use with algorithms
Many web sites for molecular biologists • They offer access to libraries of algorithms for gene-sequence analysis or protein-structure prediction. • Web-based software resources typically do not make explicit essential information, such as • the functions that the Web sites provide • the data that they can produce • the parameters that they require.
How it works • Biologists submit experimental data as web-forms • They receive results concerning matching DNA or amino-acid sequences, protein structural information, or organism identification. • These tools include database search and complex algorithmic processing for matching, prediction or constraint satisfaction.
IBROW approach • Annotate websites (algorithms and DB) with UPML • Website’s functionality is seen as PSM • KB already interoperable with PSM • Accessible to broker
Query Configure Web Monitor Map Agent-based portal for problem-solving Record User community Problem request Problem-solving methods Problem-solving methods Problem-solving methods Data UPML-Data PSM Configuration Brokering agents Result report Data Data Data Data An agent-based Web portal for intelligent problem-solving Typical situation in which a community of users interacts with our service. Users submit problem-solving requests along with sets of data grounded in a shared ontology. The brokering agents search the Web for problem-solving methods capable of processing the submitted data, according to their PSM annotations.
Agents that support a portal by mediating access to PSMs that meet users’ needs • PSM query agent: search and retrieve PSMs based on user’s request features • Domain-PSM mapping agent: map PSM requirements to user’s domain ontology • Experience-recording agent: markup cases of PSM use and mapping, for reuse and suggestion • Configuration agent: combine complementary PSM components together, compare equivalent PSMs • Monitoring agent: invoke and supervise PSM execution, user interaction, runtime data query, etc.
Applications • Addresses U.S. Department of Defense’s pervasive interest in IT to address bio-terrorism • Bio-informatics test bed portal for emergency characterization of bio-terrorist agents
Web Information Mediator • User: medical Professionals • Have several interests • Each interest is realized by a series of tasks • Task: Proactive Information Search&Organize • Automating Runtime Actions • WIM is designed with a series of tasks to further the user’s interests • Learning • about habits, interests, preferences, and resources
WIM • Accessible from a website • User defines Interests • Automatic, dynamic configuration • Interests are defined by tasks and schedules • WIM configures a “special agent” for a task • WIM executes tasks by coordinating the components
WIM services • Broker • User interaction in professional terms • Domain knowledge used by components to rank and select relevant information • For each task • Configures dynamically the components • Library has wrapper components for other resources • Results • Integrated, organized, and visualized for the user
