Having such knowledge avail able at all times would enable them to continually adjust their systems’ structure and reduce the buildup of technical debt. In the usual case\, t his (actual) architecture is unavailable: architecture recovery provides a way to recover an architectural view of the system. Many different method s and tools exist to provide such a view.\n\nThis talk will touch on the a rchitectural recovery methods proposed by researchers but focus on concern -oriented approaches. The design choices forming the bases of most existin g recovery methods mean that none of them have a complete set of desirable qualities for the purposes of development/enhancement or maintenance. Tai loring a recovery to a system is either not possible or only through itera tive experiments with numeric parameters. Furthermore\, limitations in the ir scalability make it prohibitive to apply the existing techniques to lar ge systems. Finally\, since several current recovery methods employ non-de terministic sampling\, their inconsistent results do not lend themselves w ell to tracking a systems course over several versions.\n\nAfter looking a t a few case studies of common methods\, we introduce RELAX (RELiable Arch itecture EXtraction)\, our new concern-based recovery method that uses tex t classification\, addresses these issues efficiently by (1) assembling th e overall recovery result from smaller\, independent parts\, (2) basing it on an algorithm with linear time complexity and (3) being tailorable to t he recovery of a single system or a sequence thereof through the selection of meaningfully named\, semantic topics. An intuitive\, informative archi tectural visualization rounds out RELAX's contributions. RELAX is illustra ted on a number of existing open-source systems and compared to other reco very methods.
