This e-book constitutes the completely refereed post-workshop complaints of the 1st foreign Workshop on wisdom illustration for brokers and Multi-Agent structures, KRAMAS 2008, held in Sydney, Australia, in September 2008 as a satellite tv for pc occasion of KR 2008, the eleventh overseas convention on rules of information illustration and Reasoning. the ten revised complete papers awarded have been rigorously reviewed and chosen from 14 submissions. The papers foster the cross-fertilization among the KR (knowledge illustration and reasoning) and agent groups, through discussing wisdom illustration theories and methods for agent-based platforms

Information theory: structural models for qualitative data

Krippendorff introduces social scientists to info concept and explains its program for structural modeling. He discusses key issues reminiscent of: tips on how to determine a data thought version; its use in exploratory examine; and the way it compares with different methods resembling community research, direction research, chi sq. and research of variance.

Ours To Hack and To Own: The Rise of Platform Cooperativism, a New Vision for the Future of Work and a Fairer Internet

The on-demand economic system is reversing the rights and protections employees fought for hundreds of years to win. usual net clients, in the meantime, continue little keep an eye on over their own information. whereas promising to be the nice equalizers, on-line structures have frequently exacerbated social inequalities. Can the web be owned and ruled another way?

Next, we consider closure under generated subframes (GSF) – the frame-analogue to GSM (cf. Def. 8). We also check if properties reflect GSF. A property φ reflects GSF if whenever for every frame F , it holds that every GSF of F has property φ, then so does F . We also consider closure under taking disjoint unions (DU) of frames, which are defined in the obvious way. Moreover, we look at closure under images of bisimulation systems [11], which are families of partial isomorphisms. Definition 11 (Bisimulation System).

We assume that Cb (α(i)) is finite, that pre-conditions preck , precl are mutually exclusive if k = l, and that each pre-condition has exactly one associated post-condition. We denote the set of all such pre- and post-conditions of all agents’ external actions by C. Now everything is put into place to show how the execution of α(i) in a state with brute facts set σb also univocally changes the normative facts set σn by means of the applicable counts-as rules, and adds the resulting sanctions by means of the applicable sanction rules.

Many of these notions correspond to game- and social choice-theoretical concepts. We specify the expressive power required to express these notions by determining whether they are invariant under certain relevant operations on different classes of Kripke models and frames. A large class of known extended modal languages is specified and we show how the chosen notions can be expressed in fragments of this class. To determine how demanding reasoning about cooperation is in terms of computational complexity, we use known complexity results for extended modal logics and obtain for each local notion an upper bound on the complexity of modal logics expressing it.
