Matching Techniques

One of the key tasks in the service oriented architecture that Semantic Web services aim to automate is the discovery of services that can fulfill the applications or user needs. OWL-S is one of the proposals for describing semantic metadata about Web services, which is based on the OWL ontology language. Majority of current approaches for matching OWL-S processes take into account only the inputs/outputs service profile. This chapter argues that, in many situations the service matchmaking should take into account also the process model. We present matching techniques that operate on OWL-S process models and allow retrieving in a given repository, the processes most similar to the query. To do so, the chapter proposes to reduce the problem of process matching to a graph matching problem and to adapt existing algorithms for this purpose. It proposes a similarity measure used to rank the discovered services. This measure captures differences in process structure and semantic differences between input/outputs used in the processes.

Concise Description

One of the key challenges of the Service Oriented Architecture is the discovery of relevant services for a given task. In Semantic Web Services, service discovery is generally achieved by using the service profile ontology of OWL-S. Profile of a service is a derived, concise description and not a functional part of the semantic web service. There is no schema present in the service profile to describe the input, output (IO), and the IOs in the service profile are not always annotated with ontology concepts, whereas the process model has such a schema to describe the IOs which are always annotated with ontology concepts. In this paper, we propose a complementary sophisticated matchmaking approach which uses the concrete process model ontology of OWL-S instead of the concise service profile ontology. Empirical analysis shows that high precision and recall can be achieved by using the process model-based service discovery.

Workflow-based web service compositions (WB-WSCs) is one of the main composition categories in service oriented architecture (SOA). Eflow, polymorphic process model (PPM), and business process execution language (BPEL) are the main techniques of the category of WB-WSCs. Due to maturity of web services, measuring the quality of composite web services being developed by different techniques becomes one of the most important challenges in today’s web environments. Business should try to provide good quality regarding the customers’ requirements to a composed web service. Thus, quality of service (QoS) which refers to nonfunctional parameters is important to be measured since the quality degree of a certain web service composition could be achieved. This paper tried to find a deterministic analytical method for dependability and performance measurement using Colored Petri net (CPN) with explicit routing constructs and application of theory of probability. A computer tool called WSET was also developed for modeling and supporting QoS measurement through simulation.

Much of the prior work in business process modeling is activity-centric. Recently, an information-centric approach has emerged, where a business process is modeled as the interacting lifecycles of business entities. The benefits of this approach are documented in a number of case studies. In this paper, the authors formalize the information-centric approach and derive the relationships between the two approaches. The authors formally define the notion of a business entity, provide an algorithm to transform an activity-centric model into an information-centric process model, and demonstrate the equivalence between these two models. Further, they show the value of transforming from the activity-centric paradigm to the information-centric paradigm in business process componentization and Service-Oriented Architecture design and also provide an empirical evaluation.

This article reports a series of process-based models for the development of e-business using enterprise software applications. Merging management technology in workflow systems is a critical step to provide service-oriented architecture and on-demand business. We propose a value-oriented process technique as a strategic alignment to improve investment value. Our framework focuses on the guidelines for traditional users to identify the structural conflicts in integrating Web services. A comparative study of workflow models for intra-and inter-organizational process control is presented. This article identifies the current progress in the adaptability in the design of process models coupled with structural changes of workflow views. The study provides a resource list of successful implementations for practitioners in organizational management. The research highlights the motivation of market facilitation, expert sharing and collaboration that enable commercial applications to support complex heterogeneous, autonomous and distributed information systems.

Σκοπός της παρούσας διδακτορικής διατριβής ήταν η σχεδίαση-υλοποίηση, προσομοίωση και μοντελοποίηση ασύρματων δικτύων αισθητήρων (ΑΔΑ) που βασίζονται στην αρχιτεκτονική IPv6 over low power wireless personal area networks (6LoWPAN) και υποστηρίζουν υπηρεσίες ιστού (web services) όπως επίσης και η υλοποίηση καινούριων τέτοιων υπηρεσιών καταλληλότερων για εφαρμογή στα προαναφερθέντα ΑΔΑ. Λόγω της έλλειψης που παρατηρείται στην παροχή εργαλείων για την εκπλήρωση του παραπάνω στόχου, αναπτύχθηκε ένα πειραματικό ΑΔΑ και ένα εργαλείο προσομοιωτικών μετρήσεων της επίδρασης των υπηρεσιών ιστού σε 6LoWPAN ΑΔΑ καθώς επίσης και ένα μαθηματικό μοντέλο για την μελέτη του πρωτοκόλλου ελέγχου προσπέλασης στο μέσο μετάδοσης (MAC) αυτών των δικτύων. Το προτεινόμενο MAC πρωτόκολλο για την 6LoWPAN αρχιτεκτονική είναι o χωρίς σχισμή (unslotted) CSMA/CA μηχανισμός του ΙΕΕΕ 802.15.4 προτύπου. Στα πλαίσια της παρούσας διδακτορικής διατριβής υλοποιήθηκε μια καινούρια στοίβα πρωτοκόλλων για υπηρεσίες ιστού η οποία ονομάστηκε Tiny service oriented architecture for wireless sensors (SOAWS). Το Tiny SOAWS προσφέρει μειωμένη κατανάλωση μνήμης, μειωμένο χρόνο εκτέλεσης καθώς επίσης και μειωμένα μεγέθη ανταλλασσόμενων μηνυμάτων σε σχέση με το πρότυπο device profile for web services (DPWS) το οποίο δημιουργήθηκε για την απευθείας ενσωμάτωση των υπηρεσιών ιστού σε συσκευές. Επίσης, το Tiny SOAWS υποστηρίζει την δημιουργία υπηρεσιών ιστού πάνω σε ασύρματους αισθητήρες που έχουν την ίδια σημασιολογία με τις αντίστοιχες υπηρεσίες ιστού του DPWS. Εκτός τούτου, υποστηρίζει μία καινούρια φόρμα μηνυμάτων, η οποία στηρίζεται στην extensible markup language (XML) όπως και η φόρμα μηνυμάτων του DPWS. Τα Tiny SOAWS και DPWS υλοποιήθηκαν πάνω σε πραγματικούς ασύρματους αισθητήρες και συγκρίθηκαν μεταξύ τους χρησιμοποιώντας το αναπτυχθέν πειραματικό ΑΔΑ το οποίο είναι αποτελεί ένα πραγματικό 6LoWPAN ΑΔΑ με τον μέγιστο αριθμό των ασύρματων αισθητήρων του να είναι 12. Με σκοπό την επικύρωση των παραπάνω μετρήσεων, την επέκτασή τους σε μεγαλύτερης κλίμακας ΑΔΑ καθώς επίσης και τη σύγκρισης των 2 προαναφερθέντων στοιβών πρωτοκόλλων με ένα DPWS βασισμένο σε δυαδική κωδικοποίηση (binary-based DPWS), χρησιμοποιήθηκε το αναπτυχθέν εργαλείο προσομοίωσης το οποίο υλοποιήθηκε στον προσομοιωτή network simulator (NS)-2. Επιβεβαιώθηκε η ορθή λειτουργία του πειραματικού ΑΔΑ και του εργαλείου προσομοίωσης συγκρίνοντας τις μετρήσεις του ενός με τις μετρήσεις του άλλου. Το γεγονός αυτό επιτρέπει τη χρήση τους για την αξιολόγηση και σχεδίαση 6LoWPAN ΑΔΑ που υποστηρίζουν υπηρεσίες ιστού. Επιπλέον, η σύγκριση έδειξε ότι το Tiny SOAWS υπερτερεί του DPWS. Ωστόσο, το binary-based DPWS αποτελεί την καλύτερη επιλογή. Παρόλα αυτά, η εφαρμογή του περιορίζεται σε ασύρματους αισθητήρες με συγκεκριμένο λογισμικό καθώς το σύνολο των κανόνων της XML στο οποίο στηρίζονται οι υπηρεσίες ιστού για να προσφέρουν διαλειτουργικότητα στο επίπεδο εφαρμογής δεν χρησιμοποιείται πλέον. Τέλος, οι προβλέψεις του αναπτυχθέντος μαθηματικού μοντέλου για τον unslotted μηχανισμό του MAC υπο-επιπέδου του ΙΕΕΕ 802.15.4 προτύπου συγκρίθηκαν με μετρήσεις από τον NS-2 και βρέθηκε ότι αποκλίνουν ελάχιστα. Ως εκ τούτου, μπορεί να χρησιμοποιηθεί ως εργαλείο αξιολόγησης της σχεδίασης ΑΔΑ τα οποία μπορούν μετέπειτα να υποστηρίξουν την 6LoWPAN αρχιτεκτονική καθώς επίσης και υπηρεσίες ιστού.

Traditional NM (Network Management) techniques can not be applied on WSN (Wireless Sensor Network) due to its features of low computing ability, tiny memory space, and limited energy. A new NMA (Network Management Architecture) for WSN is needed. In this paper, we design a loosely coupled NMA of WSN based on SOA (Service-Oriented Architecture), and have well defined NM interfaces. Finally, we develop a SOA platform for WSN operations according to the NMA. Based on SOA platform, users can compose and use various NM Web Services by internet depending on their requirements. Heavy tasks which need a great deal of computing resources and storage are executed on the SOA platform. Thus, energy consumption and node computation can be decreased. Moreover, external applications use Web Services to integrate SOA platform for WSN. It lowers the difficulty in integrating different sensor platforms and heterogeneous devices.

To provide better service to customers and remain competitive in the business environment, a wide variety of ready-to-use software and technologies are available for one to “grab and go” in order to build up software systems at a rapid pace. Currently, a wide variety of Web services are available and ready to use for this purpose. Current software process models also support commercial-off-the-shelf (COTS)-based development processes. However, although COTS and Web Services are similar, they are different in many perspectives. On one hand, there are various software process models that support Web services development. Yet there is no process model that supports the project that uses services provided by others. This chapter introduces the Incremental Commitment Spiral Model (ICSM), a new generation process model that provides development guidelines, from exploring a Web service alternative to deployment and maintenance with case studies.
