We argue that content-based recommendation is best suited for an environment where a database of similar user's ratings of the program is not available. Also, it is important to consider both user(More)

In this paper, we present a domain recompilationbased approach towards specifying and handling state-trajectory constraints in Hierarchical Task Network (HTN) planning paradigm. The proposed constraint specification language is inspired by the PDDL3.0 constructs. The domain-recompilation technique is based on automata templates for the PDDL modal operators.(More)
