On the emergent Semantic Web and overlooked issues

The emergent Semantic Web, despite being in its infancy, has already received a lotof attention from academia and industry. This resulted in an abundance of prototype systems and discussion most of which are centred around the underlying infrastructure. However, when we critically review the work done to date we realise that there is little discussion with respect to the vision of the Semantic Web. In particular, there is an observed dearth of discussion on how to deliver knowledge sharing in an environment such as the Semantic Web in effective and efficient manners. There are a lot of overlooked issues, associated with agents and trust to hidden assumptions made with respect to knowledge representation and robust reasoning in a distributed environment. These issues could potentially hinder further development if not considered at the early stages of designing Semantic Web systems. In this perspectives paper, we aim to help engineers and practitioners of the Semantic Web by raising awareness of these issues

Optimizing Abstract Abstract Machines

The technique of abstracting abstract machines (AAM) provides a systematic approach for deriving computable approximations of evaluators that are easily proved sound. This article contributes a complementary step-by-step process for subsequently going from a naive analyzer derived under the AAM approach, to an efficient and correct implementation. The end result of the process is a two to three order-of-magnitude improvement over the systematically derived analyzer, making it competitive with hand-optimized implementations that compute fundamentally less precise results.Comment: Proceedings of the International Conference on Functional Programming 2013 (ICFP 2013).

Similarity-based Techniques for Trust Management

A network of people having established trust relations and a model for propagation of related trust scores are fundamental building blocks in many of todayŠs most successful e-commerce and recommendation systems. Many online communities are only successful if sufficient mu-tual trust between their members exists. Users want to know whom to trust and how muc

Analysing Business Models for Cross Border E-Services Provided by the Chambers of Commerce

The term "Business Model" started to gain momentum in the early rise of the new economy and it is currently used both in business practice and scientific research. Under a general point of view BMs are considered as a contact point among technology, organization and strategy used to describe how an organization gets value from technology and uses it as a source of competitive advantage. Recent contributions suggest to use ontologies to define a shareable conceptualization of BM. The aim of this study is to investigate the role of BM Ontologies as a conceptual tool for the cooperation of subjects interested in achieving a common goal and operating in complex and innovative environments. This is the case for example of those contexts characterized by the deployment of e-services from multiple service providers in cross border environments. Through an extensive literature review on BM we selected the most suitable conceptual tool and studied its application to the LD-CAST project during a participatory action research activity in order to analyse the BM design process of a new organisation based on the cooperation of service providers (the Chambers of Commerce from Italy, Romania, Poland and Bulgaria) with different needs, legal constraints and cultural background.The term "Business Model" started to gain momentum in the early rise of the new economy and it is currently used both in business practice and scientific research.

Контроль логических выводов в семантических базах данных

Рассматривается метод решения задачи контроля доступа пользователей к семантическим базам данных, содержащим простые утверждения, состоящие из трех элементов (триплетов). Использование данного метода позволяет не допустить получения данных, на основе которых пользователи могут логически вывести не разрешенную им информацию. Сделана постановка задачи контроля логических выводов на получаемых данных, и предложены алгоритмы ее решения

Personnel performance assessment in information systems outsourcing environments

Paper presented at the 3rd World Summit on the Knowledge Society (WSKS 2010), Corfu, Greece, September 22-24, 2010Purpose – The aim of this paper is to present a tool which uses semantic technologies for personnel performance and workplace learning assessment in outsourced information technology environments. Design/methodology/approach – The paper presents the tool from a technical perspective and introduces a use case that depicts the main features related to human resource management issues. Findings – Semantic technologies enable the monitoring of personnel throughout all of the phases of the management of outsourcing, basing itself on established communication standards used in leading business management tools and recent outsourcing efforts. This monitoring provides to human resource management issues an integrated approach to assess both employee performance and learning outcomes as a result of competence evaluation. Originality/value – The paper shows that semantic technologies can be applied to human resource management tools to bring its intrinsic characteristics to human resource management tasks including personnel and learning assessment
