Popis: A new complexity model for web queries is presented in this paper. The novelties of this model are: (1) the communication cost is considered; (2) the complexity of a web query is partitioned into the accessing complexity and the constructing complexity; (3) the classical complexity classes of queries are redefined. The upper bound of this model is the class TAC-Computable. A language which captures exactly the class is presented.
