We construct the inverse partition semigroup IPX , isomorphic to the dual symmetric inverse monoid I∗ X , introduced in [6]. We give a convenient geometric illustration for elements of IPX . We describe all maximal subsemigroups of IPX and find a generating set for IPX when X is finite. We prove that all the automorphisms of IPX are inner. We show how to embed the symmetric inverse semigroup in...

Gramsican approaches in International Relations (IR) have sought to outline the relationship between ideas and material forces in the construction of world order. Scholars working within this broad school have sought to emphasise that ideas are material forces, and must be considered as concrete historical structures (Cox, 1987) central to the establishment of particular historical and hegemoni...

Vila na Rede is an Inclusive Social Network (ISN) system developed as a joint effort with Brazilian communities. As a product of e-Cidadania's Project, it has inherited the objective of being accessible for the widest variety of users, including those less familiar with technology or with low literacy levels. In this direction, different features were incorporated into Vila na Rede in order to ...

Modern businesses operate in a rapidly changing environment. Continuous learning is an essential ingredient in order to stay competitive in such environments. The APOSDLE system utilizes semantic web technologies to create a generic system for supporting knowledge workers in different domains to learn@work. Since APOSDLE relies on three interconnected semantic models to achieve this goal, the q...

Our proposal, identifying sentiments in N -grams (ISN), focuses on both word order and phrases, and the interdependency between specific ratings and corresponding sentiments in texts to detect subjective information.

The research of impacts between the Internet stock news (ISN) and the stock price movements emerges with the era of the popular usage of the Internet. In this paper, first, the ISN is empirically related to the stock returns based on the neural networks. Second, the relationship between the significant increases of the ISN volume and the significant changes of stock prices is addressed, also im...

Social Networking Sites (SNS) are one of the most popular business models on the Internet at the moment. At the same time, Social Networking is increasingly interesting as a topic of research in Information Systems. Drawing on existing research in the field, in this paper we propose to distinguish ISN (Internet Social Networking) as a phenomenon from its concrete manifestations in the various S...
