In 1974 an article appeared in Science magazine with the dry-sounding title “Judgment Under Uncertainty: Heuristics and Biases” by a pair of psychologists who were not well known outside their discipline of decision theory. In it Amos Tversky and Daniel Kahneman introduced the world to Prospect Theory, which mapped out how humans actually behave when faced with decisions about gains and losses, in contrast to how economists assumed that people behave. Prospect Theory turned Economics on its head by demonstrating through a series of ingenious experiments that people are much more concerned with losses than they are with gains, and that framing a choice from one perspective or the other will result in decisions that are exactly the opposite of each other, even if the outcomes are monetarily the same. Prospect Theory led cognitive psychology in a new direction that began to uncover other human biases in thinking that are probably not learned but are part of our brain’s wiring.

Tools and Algorithms for the Construction and Analysis of Systems. Proc. TACAS 2009

The Object Management Group's (OMG) Model Driven Architecture (MDA) strategy envisages a world where models play a more direct role in software production, being amenable to manipulation and transformation by machine. Model Driven Engineering (MDE) is wider in scope than MDA. MDE combines process and analysis with architecture. This article sets out a framework for model driven engineering, which can be used as a point of reference for activity in this area. It proposes an organisation of the modelling 'space' and how to locate models in that space. It discusses different kinds of mappings between models. It explains why process and architecture are tightly connected. It discusses the importance and nature of tools. It identifies the need for defining families of languages and transformations, and for developing techniques for generating/configuring tools from such definitions. It concludes with a call to align metamodelling with formal language engineering techniques.

[서평]「Component Software」 - Beyond Object-Oriented Programming -

Service-oriented computing is now acknowledged as a central paradigm for Internet computing, supported by tremendous research and technology development over the last 10 years. However, the evolution of the Internet, and in particular, the latest Future Internet vision, challenges the paradigm. Indeed, service-oriented computing has to face the ultra large scale and heterogeneity of the Future Internet, which are orders of magnitude higher than those of today’s service-oriented systems. This article aims at contributing to this objective by identifying the key research directions to be followed in light of the latest state of the art. This article more specifically focuses on research challenges for service-oriented middleware design, therefore, investigating service description, discovery, access, and composition in the Future Internet of services.

Service-oriented middleware for the Future Internet: state of the art and research directions

Formal methods offer an effective means to assert the correctness of software systems through mathematical reasoning. However, the need to formulate system properties in a purely mathematical fashion can create pragmatic barriers to the application of these techniques. For this reason, Dwyer et al. invented property specification patterns which is a system of recurring solutions to deal with the temporal intricacies that would make the construction of reactive systems very hard otherwise. Today, property specification patterns provide general rules that help practitioners to qualify order and occurrence, to quantify time bounds, and to express probabilities of events. Nevertheless, a comprehensive framework combining qualitative, real-time, and probabilistic property specification patterns has remained elusive. The benefits of such a framework are twofold. First, it would remove the distinction between qualitative and quantitative aspects of events; and second, it would provide a structure to systematically discover new property specification patterns. In this paper, we report on such a framework and present a unified catalogue that combines all known plus 40 newly identified or extended patterns. We also offer a natural language front-end to map patterns to a temporal logic of choice. To demonstrate the virtue of this new framework, we applied it to a variety of industrial requirements, and use PSPWizard , a tool specifically developed to work with our unified pattern catalogue, to automatically render concrete instances of property specification patterns to formulae of an underlying temporal logic of choice.

Temporal logics are commonly used for reasoning about concurrent systems. Model checkers and other finite-state verification techniques allow for automated checking of system model compliance to given temporal properties. These properties are typically specified as linear-time formulae in temporal logics. Unfortunately, the level of inherent sophistication required by these formalisms too often represents an impediment to move these techniques from "research theory" to "industry practice". The objective of this work is to facilitate the nontrivial and error prone task of specifying, correctly and without expertise in temporal logic, temporal properties. 

In order to understand the basis of a simple but expressive formalism for specifying temporal properties we critically analyze commonly used in practice visual notations. Then we present a scenario-based visual language called Property Sequence Chart (PSC) that, in our opinion, fixes the highlighted lacks of these notations by extending a subset of UML 2.0 Interaction Sequence Diagrams. We also provide PSC with both denotational and operational semantics. The operational semantics is obtained via translation into Buchi automata and the translation algorithm is implemented as a plugin of our Charmy tool. Expressiveness of PSC has been validated with respect to well known property specification patterns.

Graphical scenarios for specifying temporal properties: an automated approach

SYNTHESIS is a tool for automatically assembling correct and distributed component-based systems. In our context, a system is correct when it is deadlock-free and performs only specified component interactions. In order to automatically synthesize the correct composition code, SYNTHESIS takes as input an high-level behavioural description for each component that must form the system to be built and a specification of the component interactions that must be enforced in the system. The automatically derived composition code is implemented as a set of distributed component wrappers that cooperatively interact with each other and with their wrapped components in order to prevent possible deadlocks and make the composed system exhibit only the specified interactions. The current version of SYNTHESIS supports two possible development platforms: Microsoft COM/DCOM, and EJB (Enterprise Java Beans).

SYNTHESIS: A Tool for Automatically Assembling Correct and Distributed Component-Based Systems

The near future envisions a pervasive heterogeneous computing infrastructure that makes it possible for mobile users to run software services on a variety of devices, from networks of devices to stand-alone wireless resource-constrained ones. To ensure that users meet their non-functional requirements by experiencing the best Quality of Service according to their needs and specific contexts of use, services need to be context-aware and adaptable. The development and the execution of such services is a big challenge and it is far to be solved. In this paper we present our experience in this direction by describing our approach to context-aware adaptive services within the IST PLASTIC project. The approach makes use of Chameleon , a formal framework for adaptive Java applications.
