Enquiries: Dr Malcolm Newey

Scientific workflows are used to connect together different data sources, components and processes to support research. These interacting components and processes are usually developed independently and may not be directly compatible, requiring considerable effort to integrate them. The execution-centric and implementation-focused nature of existing workflow management methodologies forces scientists to work at the low level of workflow orchestration and implementation. This makes it difficult and time-consuming to verify the provenance of and reuse existing workflows in a new context.

Omnispective Analysis and Reasoning lifts the process of scientific workflow management to a higher level of abstraction in order to support the effective capture and reuse of concepts and ideas (intellectual effort). The research tackles workflow context, provenance and agility at the concept, model and execution levels of scientific workflow management.

Improved support for these concerns will make it easier to rapidly form and evaluate research hypotheses. This will greatly enhance the scientist’s ability to understand and intervene in a rapidly changing world.

This seminar is part of the CECS Seminar Series.

Srinivas Chemboli is a PhD student in the Software Intensive Systems Engineering Group at the School of Computer Science.

Seminar: Seeing the World through Indian Foreign Service Eyes – A Blueprint for ‘Diplomatic’ Fieldwork

Greetings from the Coombs Seminar Room A at The Australian National University where India specialist Kate Sullivan is presenting Seeing the World through Indian Foreign Service Eyes — A Blueprint for ‘Diplomatic Fieldwork’ in the study of International Relations (IR).

The talk and topic is particularly interesting to me in that the study readily lends itself to the application of Aspect-Oriented Thinking (a multidisciplinary methodology developed by Dr Shayne Flint) in tackling the integration of the necessary domain knowledge and structure.

In the first part of her talk, Ms Sullivan makes the following interesting points about IR study.

IR is not culturally-neutral: This affects the study of IR theories due to the following factors:

  • Complexity
  • Epistemology
  • Universalist assumptions
  • IR’s ‘debt to the West’

Reforming the discipline of IR study: These issues have been recognized by intellectuals and efforts are underway to reform the discipline, in particular the handling of culture in the context of

  • Foreign Policy Analysis
  • Strategic Studies

IR studies are obviously multi-, inter- and trans-disciplinary in nature, encountering issues which can to a large extent be ameliorated by exploiting interpretive contexts. This work presents interesting cross-cutting concerns with current research across The Australian National University by Ziyad Alshaikh in management of context, suggesting effective use of a Context Dynamics Matrix.

In the second part of her talk, Ms Sullivan visits the debate surrounding the narrative exploration in her research studies, successfully arguing a case for contextualizing the implicit nature of theories and methodologies in asking questions about India’s aspirations to be an institutionally recognized ‘global power’.

Finally, Ms Sullivan outlined the effects various drivers and forces governing Indian foreign policy decisions and their resulting outcomes. She argued that we should look at the context of the narrative concerns at a sufficient level of abstraction and detail and map it to an ethnographic effect. This entails a view of the Indian Foreign Service from a perspective of:

  • Data collection/study/interpretation
  • ‘Emic’ (insider) verus ‘etic’ (outsider) approach
  • Attempt to grasp the making of meaningful social behavior
  • Encourage reflexivity on part of the researcher

These research questions are not too different from the questions I seek to answer in the field of contextual concept workflow management (answering the four canonical questions of who, what, when, why), and the need to explicitize the context-tie-in.

Ms Sullivan also suggested that there is a progressive change in the sensitivity with which India has projected its image abroad and in the international arena. She discussed what makes the study of historical and current ethnographies challenging and how academic research could manage ‘in-the-field’ analysis of individuals who seek to inform public policy in international relations.

Finally, there was some time spent in general discussion and questions on issues affecting studies in International Relations. Points raised recognized the need to resolve cultural forces, challenges in marrying inconsistencies between theoretical and practical approaches and the academic material in the context of this research.

Seminar: Generating Operational Guidelines from ATL Transformations

AOT Logo

Speaker: Rainbow Cai, Lecturer, Department of Computer Science (DCS, ANU)

Date: Thursday, 30 April 2009

Time: 4:00 PM – 5:00 PM
Venue: CSIT Seminar Room, N101, CSIT Building, Building (108), North Road, ANU (campus map)

Enquiries: Dr Shayne Flint

Model transformation, a core part of Model Driven Engineering, transforms models from one format to another. Model Transformation is normally done with transformation languages, such as ATL, XSLT, or programming language (e.g. java). Currently, transformation programs are written to achieve the basic transformation goal, i.e. transforming a model from one format to another.

As model transformation programs are well-structured information and implicitly contain the rationale, the conditions, and the results of an intended transformation, we argue that the potential of transformation programs needs to be explored to provide guidelines for currently isolated operational tasks such as detecting semantic inconsistencies, providing behaviour synchronisation information, and establishing traceability among models. In this paper, we introduce the CRelation model – a generic analysis and design model for model transformation, and use the CRelation model to assist the development of ATL transformation programs. From within the CRelation model, we then use the ATL programs to generate guidelines for the operational tasks related to model transformation. We demonstrate the feasibility of our approach with a case study and present the initial evaluation results.

This seminar is part of the DCS Seminar Series.

Rainbow Cai is a lecturer at the Computer Science Department, ANU. She did her PhD in Software Engineering at the Department of Computer Science, University of Auckland.

She holds undergraduate diploma, postgraduate diploma, and master of science degree (with honors), all in Computer Science, from University of Auckland. Rainbow has active research interests in the areas of software architecture modelling, software architecture performance evaluation, reverse engineering, domain-specific modelling language, automated software engineering, visual languages and environments, meta-tools for multi-view multi-notation design tools, and model transformation and integration. Her main areas of interest pertain to software architecture modelling, performance engineering, and model transformation and integration.
