Until now we focused on the automatic classification of poems and the suggestion of the ending word for a verse. The classification module is based on poetic concepts that take into account structure and metrics. The prediction module uses several criteria to select the ending word: the structural constraints of the poem, the grammatical category of the words, and the statistical language models obtained from a text corpus. The first version of the system, rather than being selfcontained, is still based on the use of different heterogeneous modules. We are currently working on a second version based on a modular architecture that facilitates the reuse of the linguistic processing modules already developed within the lab.

The implementation of these facilities requires a new flexibility from the technological framework able to cope with the complex distributed cooperative processes crossillg different companies. This paper describes the strategy adopted by the ITS-IBus project to promote a /lew orga/lization for the to/l underlying technologies. able to create the conditions to challenge new, flexible and innovative services. The adoption of a service based framework associated to the definition of a set of open interfaces based on existing standards is discussed.

The lack of standards or differences in implementations when they exist, are important obstacles to the construction of integrated, flexible and agile solutions. The incorporation of systems from different vendors and systems that evolve to answer innovation processes, suggests the advantage for a multi-technology systems strategy. This paper discusses the ITSIBus approach based on, a multi-technology service oriented infrastructure where specialized pluggable systems run services following a peer to peer architecture. The multi-technology approach is based on the discussed System Broker concept. The agility required by a crescent number of collaborative business process requires an advanced flexibility from the ICT technological infrastructure. The ITSIBus approach is also discussed as a grounding platform to support enterprise collaborative networks considering that services in different companies are based on different technologies.

The extension of Via-Verde concept to other services beyond the motorway toll collection has increased the number of independent companies involved. The complex networked scenario resulted on a proposal of an intelligent transport system — interoperability bus (ITS-IBus) (Gomes et. al. 2003) (Osorio, et. al. 2003-a) aiming to promote a generalized interoperability among heterogeneous (multi-vendor) technological subsystems. The ITS-IBus initiative has been developing since then, a reference implementation of a peer-to-peer service based framework with pluggable feature and a set of common agreed interfaces for coupling different technological systems. An important objective is to increase the quality of the offered services by establishing a flexible execution and coordination framework for the collaborative distributed bus...
