Matchmaking based on task and capability description

It is the foundation for agent cooperation that understanding between agents in a multi-agent environment. It implies that the service agents should describe their capabilities and the requisition agents or users describe their tasks in a suitable manner and make both of them to be known by the matchmakers and other agents before any advertisement, request or matchmaking took place. In this paper, we discussed the methods to describe task and capability and make match between them with domain ontology. Both task and capability can be described by input and output with parameters and constraints, so we can accomplish matchmaking by two steps, which are parameter implication and constraint satisfaction. The former deals with concept matching and the latter constraints matching. Meanwhile, domain ontology will play an important role.
