Annual IEEE/ NASA Goddard Workshop on Software Engineering

作者： Tiziana Margaria Bernhard Steffen Chair of Service and Software Engineering University of Potsdam Potsdam Germany Chair of Programming Systems University of Dortmund Dortmund Germany

We revisit the automatic tool composition feature of the electronic tool integration platform under the perspective of planning. It turns out that in todays terminology, ETIs temporal logic-based synthesis of tool sequences is a form of planning-based automated orchestration. In contrast to Al-based planning approaches, our synthesis approach is not restricted to compute one solution, but it may compute all (shortest/minimal) solutions, with the intent to provide maximum insight into the potential design space.

International Workshop on Automated Specification and Verification of Web systems, WWV

作者： Martin Karusseit Tiziana Margaria Chair of Programming Systems Universität Dortmund Germany Chair of Service and Software Engineering Universität Postdam Germany

Today Web-based applications are very complex and provide several hundred users with access to sensible data. Adequate access control mechanisms that prevent unauthorized access and gives policy-compliant access to users depending on their status are thus central. The online conference service (OCS) is a system of services which collectively provide all necessary workflows and functionalities an online decision support service needs. Here we describe its flexible role-based access control mechanism and introduce the embedded role management service, which is extensible, modifiable and reconfigurable online, during the service operations. We also discuss a first version of the personalized role management service as used in the OJS, the journal member of the product line initiated by the OCS

IEEE/ACS International Conference on Pervasive Services (ICPS)

作者： M. Bajohr T. Margaria Chair of Programming Systems University of Dortmund Germany Service Engineering for Distributed Systems Universität Gottingen Germany

With MaTRICS, we describe an architecture for pervasive management of distributed systems. It allows remotely connected users (e.g., system administrators) to modify the configuration of any service provided by a specific (application) server, like email-, news- or Web-servers. Novel to our approach is that the system can manage configuration processes on heterogeneous software- and hardware- platforms, which are performed from a variety of peripherals unmatched in today's practice. In this sense, we realize a sort of pervasive system management, where devices like mobile phones, faxes, PDAs are enabled to be used by system managers as remote system configuration and management tools.

IEEE International Conference on Engineering of Complex Computer systems

作者： T. Margaria C. Kubczak M. Njoku B. Steffen Chair Servce and Software Engineering University of Potsdam Potsdam Germany Chair of Programming Systems University of Dortmund Dortmund Germany Chair of Service Engineering for Distributed Systems University of Göttingen Gottingen Germany

Our approach to the model-driven collaborative design of workflows for bioinformatic applications uses the jABC for model driven mediation and choreography to complement a Web service-based elementary service provision. jABC is a framework for service development based on lightweight process coordination. Users (product developers and system/software designers) develop services and applications by composing reusable building-blocks into (flow-)graph structures that can be animated, analyzed, simulated, verified, executed, and compiled. This way of handling the collaborative design of complex processes has proven to be effective and adequate for the cooperation of non-programmers (in this case biologists) and technical people, and it is now being rolled out in the operative practice

Dialog-Based Meaning Derivation Service for Technical Language Domains

International Conference on Semantic Computing

作者： Alexander Wachtel Sophie Schulz Walter F. Tichy Chair for Programming Systems Prof Walter F. Tichy Karlsruhe Institute of Technology Karlsruhe Germany

In our previous work, we present on how new algorithms can be recognized and learned from human descriptions. In this case, end users are able to extend the given system by their own functionality. During the evaluation, due to language limits on the system, it could interpret only 59 % of user input correctly. In this paper, we provide an approach on the Dialog-based Meaning Derivation Service (DMDS). In case, user input does not match to the system knowledge, DMDS serves various word networks to find relevant synonyms as candidates for the unknown word. DMDS then tries to verify these candidates to the given knowledge base. Finally, matched candidates are presented to the end user by the dialog system for confirmation of a contextual match. The meaning is learned after the user confirmation and is mapped to the given functionality, and can be used afterwards. Therefore, the model developed in this work can be categorized as supervised learning. Finally, both the performance and the quality recorded by input from a user study were examined. However, DMDS improves the correct interpretation of the system from 59 % to 82 %. Our focus is to improve the interaction between humans and machines and enable the end user to instruct programmable devices, without having to learn a programming language.

Initial Implementation of Natural Language Turn-Based Dialog System

引用

Procedia Computer Science 2016年 84卷 49-56页

作者： Alexander Wachtel Sebastian Weigelt Walter F. Tichy Karlsruhe Institute of Technology Chair for Programming Systems Prof. Walter F. Tichy Am Fasanengarten 5 76131 Karlsruhe Germany

Our prototype implements a natural language dialog system for Excel spreadsheets. The work is motivated by a pilot study which shows that novice users have difficulties with the formula language of Excel and need interactive assistance. JustLingo 1 allows spreadsheet calculations in ordinary, written English. Furthermore, users can extend the system functionality by explaining of the calculations to the prototype. The keyword-based system analyzes the input using natural language processing techniques and translates it into Excel formulas. It asks for missing information such as operands and target cells and provides alternatives if there are ambiguities. It also handles references to previous inputs, allowing step-by-step construction of calculations. An evaluation shows that it properly resolves 82% of references and correctly interprets 79,5% of overall user input. Although far from perfect, the prototype demonstrates that computers may soon begin to take on simple, limited-domain programming tasks based on natural-language input.

IEEE European Test Symposium (ETS)

We show how our integrated test environment can be used for the validation of evolving Internet services, since it captures the (re-)configuration phase preceding the 'classical' steady state usage. This capability is extremely important to test applications and products based on the high-end HICOM switch family: via a specific application they allow the remote, web-browser and Internet-based configuration of services built upon a new-generation, virtual switch. The paper illustrates this capability while focussing on the challenge of dealing with high availability systems.

作者： Christian Kubczak Tiziana Margaria Arno Fritsch Bernhard Steffen Chair of Software Engineering University of Dortmund Germany Chair of Service and Software Engineering University of Potsdam Germany Chair of Mathematical Statistics and Biometric Applications University of Dortmund Germany Chair of Programming Systems University of Dortmund Germany

LC/MS is a successful analysis technique for the statistical analysis used in several branches of biology. It requires an intense screening and combination of the raw data, which is usually done with programs and libraries invoked by scripts in the domain-specific statistics language S or R. We show here how to model and implement this complex workflow in a service-oriented fashion, using the jABC service definition environment and jETI for remote service integration and execution.

International Symposium on Leveraging Applications of Formal Methods, Verification and Validation ( ISoLA)

作者： Tiziana Margaria Christian Kubczak Bernhard Steffen Stefan Naujokat Chair of Service and Software Engineering Universität Postdam Potsdam Germany Chair of Software Engineering Universität Dortmund Dortmund Germany Chair of Programming Systems Universität Dortmund Dortmund Germany

One of the goals of FMICS, the ERCIM Working Group on Formal Methods for Industrial Critical systems (FMICS) [8], is to transfer and promote the use formal methods technology in industry. The ongoing Verified Software Repository Grand Challenge [11] offers a great opportunity to reach this goal, resulting in a more robust and solid software industry in Europe. We demonstrate here the current status of the FMICS-jETIplatform1, a collaborative demonstrator based on the jETI technology2, that provides as repository a collection of verification tools stemming from the activities of the FMICS working group and facilities to orchestrate them in a remote and simple way. At the same time FMICS-jETI itself is a contribution to the VSR repository and thus to the Grand Challenge.
