ODESWS, A Semantic Web Service Development

ODE SWS is a development environment to design Semantic Web Services (SWS) at the knowledge level. ODE SWS describe the service following a problem-solving approach in which the SWS are modeled using tasks, to represent the SWS functional features, and methods, to describe the SWS internal structure. In this paper, we describe the ODE SWS architecture and the capabilities of its graphical interface, which enables users to design SWS independently of the semantic markup language used to represent them

SWSDesigner: The Graphical Interface of ODESWS

ODESWS is a development environment to design Semantic Web Services (SWS) at the knowledge level. ODESWS describe the service following a problem-solving approach in which the SWS are modelled using tasks, to represent the SWS functional features, and methods, to describe the SWS internal structure. In this paper, we describe the ODESWS graphical interface (called SWSDesinger). This interface enables users to design SWS independently of the semantic markup language in which the service will be implemented, and once the design has been export the service to an SWS implementation languag

A Framework for Design and Composition of Semantic Web Services

Semantic Web Services (SWS) are Web Services (WS) whose description is semantically enhanced with markup languages (e.g., OWL-S). This semantic description will enable external agents and programs to discover, compose and invoke SWSs. However, as a previous step to the specification of SWSs in a language, it must be designed at a conceptual level to guarantee its correctness and avoid inconsistencies among its internal components. In this paper, we present a framework for design and (semi) automatic composition of SWSs at a language-independent and knowledge level. This framework is based on a stack of ontologies that (1) describe the different parts of a SWS; and (2) contain a set of axioms that are really design rules to be verified by the ontology instances. Based on these ontologies, design and composition of SWSs can be viewed as the correct instantiation of the ontologies themselves. Once these instances have been created they will be exported to SWS languages such as OWL-S

Spontaneous emergence of contrarian-like behaviour in an opinion spreading model

We introduce stochastic driving in the Sznajd model of opinion spreading. This stochastic effect is meant to mimic a social temperature, so that agents can take random decisions with a varying probability. We show that a stochastic driving has a tremendous impact on the system dynamics as a whole by inducing an order-disorder nonequilibrium phase transition. Interestingly, under certain conditions, this stochastic dynamics can spontaneously lead to agents in the system who are analogous to Galam's contarians.Comment: 4 eps figs, EuroPhys Lett styl

Making the match between content and foreign language: A case study on university students’ opinions towards CLIL

The present article intends to show the positive evaluation of post-graduate university students at a Spanish university after the curricular integration experience and the application of CLIL scaffolding techniques. It also aims to identify areas of methodological improvements and recommendations in the application of CLIL in the referred programme as well as in higher education contexts. The researchers used a cross-sectional study to survey the students’ opinion on ICL after the integration of the syllabus of one foreign language subject and another content subject in a post-graduate degree at a private Spanish university in Madrid (Spain). The results point to a positive view of CLIL from Spanish higher education post-graduate students. The survey results also seem to show the students’ confidence in CLIL for their English-led classes aids them to simultaneously increase their foreign language acquisition and their nonlinguistic contents learning. However, researchers detected certain linguistic scaffolding aspects appear to need further students’ training and teachers’ methodological adjustments, as they can negatively affect learners’ engagement and hence, their learning outcomes. The authors note more research is needed to collect data from a wider population and increase the reliability of the results.DOI: 10.18870/hlrc.v5i1.23

INTELLECTUAL PROPERTY RIGHTS FOR SOFTWARE DATA AND DOD ACQUISITION POLICIES AS THEY PERTAIN TO SMALL BUSINESSES

Intellectual property (IP) rights play an important role in DOD acquisition by providing a framework for competition, innovation, and technological trajectory. Poorly defined data rights can be problematic for the DOD and can strangle innovation that might otherwise be useful to the public. Small businesses that lack adequate resources required to cater to the extensive acquisition requirements of the government may be subjected to unfair competition, slow or no growth opportunities, and prejudiced innovation. Furthermore, small businesses might face challenges in complying with the extensive DOD acquisition parameters, thus disincentivizing them from engaging in business with the government. This research explores the effectiveness of the current DOD acquisition policies and procedures governing intellectual property rights and examines how these data rights policies apply to and affect small businesses. The methodology herein includes an in-depth literature review of existing legislative and policy initiatives and their effectiveness in the Small Business Innovation Research (SBIR) program. The findings determine that the current DOD policies and procedures are disadvantageous to small businesses and create a negative perception of the DOD acquisition process. This research recommends reframing the existing training and continuing education programs of the DOD acquisition workforce in order to improve and encourage successful IP acquisitions with small businesses.Lieutenant, United States NavyCivilian, Harmony Technology Services IncApproved for public release.

Phase transition in the Sznajd model with independence

We propose a model of opinion dynamics which describes two major types of social influence -- conformity and independence. Conformity in our model is described by the so called outflow dynamics (known as Sznajd model). According to sociologists' suggestions, we introduce also a second type of social influence, known in social psychology as independence. Various social experiments have shown that the level of conformity depends on the society. We introduce this level as a parameter of the model and show that there is a continuous phase transition between conformity and independence

An Environment for Development of Semantic Web Services

Semantic Web Services (SWSs) are specified in a semantic markup language to enable other services (and agents) to reason about their capabilities, in order to decide whether a SWS should be invoked or not. In this paper an environment for development and description of SWSs is presented. This environment, called ODE SWSDesigner, consists of a graphical interface, which allows users to carry out the design and characterization of SWSs at a conceptual level, and a set of software modules, which verify the design correctness and perform the translations from the graphical descriptions to the languages used to specify SWSs. ODE SWSDesigner provides support for a layer-based framework that we have proposed with the aim of enabling a language -independent development of SWSs. This framework is based on the use of problemsolving methods that are considered as highlevel specifications from which SWS descriptions can be generated and verified
