Conflict Management for Constraint-based Recommendation

An Overview of Direct Diagnosis and Repair Techniques in the WEEVIS Recommendation Environment∗

Constraint-based recommenders support users in the identification of items (products) fitting their wishes and needs. Example domains are financial services and electronic equipment. In this paper we show how divide-and-conquer based (direct) diagnosis algorithms (no conflict detection is needed) can be exploited in constraint-based recommendation scenarios. In this context, we provide an overv...

iCone: Intelligent Environment for the Development and Maintenance of Configuration Knowledge Bases

Constraint-based recommendation systems are used in many different domains like notebooks, cars, and mobile phones. Such systems describe product domains in sets of product and customer variables, their domains, and constraints which define the relationship between the variables. Maintenance is a crucial task in constraint-based recommendation systems, because it is timeconsuming and error-pron...

Mediated Conflict Recovery by Constraint Relaxation

Dynamic events in a multiagent environment can be a source of conflict. We model the network of inter-agent commitments as a constraint graph. Conflicts arise when an event prevents fulfillment of a commitment, resulting in an infeasible constraint graph. Constraint relaxation directed by a mediating agent is used to reconfigure the commitment graph. We investigate this general approach in the ...

DECLARE Demo: A Constraint-based Workflow Management System

Mainstream workflow management systems are using procedural languages ranging from BPMN and EPCs to BPEL and YAWL. By demonstrating DECLARE, we will show that it is also possible to use a fundamentally different approach based on constraints. DECLARE allows for multiple constraint-based languages whose semantics are grounded in Linear Temporal Logic (LTL). The DECLARE system provides a broad ra...
