A bottom-up ontological approach for integrating heterogeneous web services and their incremental usage semantics representation is described. The results of comparative analysis of our proposed ASTRA approach with other related ones in appropriate research fields, are provided. Formal model of proactive information system corresponding to this ASTRA approach, allowing creation of a smart intermediate layer between a set of heterogeneous web services and end-user applications based on them, is presented. This proactive information system is being implemented as middleware, and its multilayer architecture is also decribed. This ASTRA software allows solving the following issues in mobiquitous information systems: services usage situation analysis, detection of useful services patterns (heuristics for solving typical user tasks), and also services search and generation for any given situation. Thus it helps to provide users with services which are more appropriate to concrete usage situations. Finally conclusion and outcome of our ASTRA project along with future research directions are given.
