Among various Information Technologies, the Workflow Management System greatly improves the efficiency of business processes. The challenge for Workflow Systems relies on their ability to align ICT and the processes of production and business. They should support the strategic policy of the enterprise and quickly respond to on-demand business and opportunities. Unfortunately, they suffer from some lacks and limitations due to their monolithic architectures. Most Workflow Management Systems are dependent on technology platforms and partially conform to standards. We attempt throughout the present paper to propose the next generation of Workflow architectures. We conceive workflow systems as a set of services, which are generic and platform-independent. Services are self-contained and fully-customized. Workflow services are assembled from computational components (i.e. web services), which are loosely coupled. The new architecture is split into layers to guarantee a high level of abstraction, each of which is managed by a crucial Web Service known as the orchestrator service.10aDesign tools and techniques10aIntegrated environment10aInteroperability10aSoftware architectures10aStandards10aWorkflow management1 aBadr, Y.  uhttp://www.scopus.com/inward/record.url?eid=2-s2.0-56849115934&partnerID=40&md5=00c78de5d2932b1fff3748d5f163697400453nas a2200133   4500008004100000245005200041210005200093260000900145300001400154490000600168100001300174700001500187856011700202       2008                        eng d00aSpecial issue on digital information management0 aSpecial issue on digital information management  c2008  a281 - 2840 v61 aBadr, Y.1 aChbeir, R.  uhttp://www.scopus.com/inward/record.url?eid=2-s2.0-70349983276&partnerID=40&md5=3307d00e9cbb24d7342a1b1218e9ac2001832nas a2200181   4500008004100000245007000041210006900111260000900180300001400189490000600203520122600209653001801435653002901453653001701482653002101499100001301520856011701533       2006                        eng d00aExtracting information from coarser-grained data in XML documents0 aExtracting information from coarsergrained data in XML documents  c2006  a117 - 1230 v43 aXML is fast emerging as the dominant standard for representing data in the applications centric documents. While there has been a great deal of works recently proposing the extraction of relevant data of natural langujge texts, Most of the underlying works confront with the irregular structure hidden in the text. To this end, a large spectrum of wrappers has been conceived lot- web pages. Unfortunately, they cannot deal with semi-structured data and cannot still take into consideration the natural language processing. In this paper, we present a specification language to write expressive and easy extraction patterns. The specification relies on rectular expression fashion in order to write patterns by non expert users. In addition, we introduce the Xtractor wrapper for coarser-grained data (i.e. paragraphs). The Xtractor hinges on linguistic parsing. of paragraphs and applies technical and natural language dictionaries. Then it employs the extraction patterns against the pre-processed paragraphs in order to locate relevant data. The key idea of our approach consists of translating the extraction patterns to Finite State Transducers (FST) and even using the FST to build the domain specific dictionaries.10aData exchange10aFinite state transducers10aXML database10aXtractor wrapper1 aBadr, Y.  uhttp://www.scopus.com/inward/record.url?eid=2-s2.0-44649098973&partnerID=40&md5=e3df331dc7e1172e6d94226eecc4f744
