The connection method earned good reputation in the field of automated theorem proving for around three decades, due to its simplicity, clarity, efficiency and parsimonious use of memory. This seems to be a very appealing feature, in particular in the context of Semantic Web, where it is assumed that the knowledge bases might be of arbitrary size. In this paper, I present a connection method es...

Reputation systems provide a form of social control and reveal behaviour patterns in the uncertain and riskladen environment of the open Internet. However, proposed reputation systems typically focus on the effectiveness and accuracy of reputation management, and suffer from a number of common vulnerabilities. As a result, introducing reputation management into the business environment may only...

Reputation systems have become an increasingly important tool for highlighting quality information and filtering spam within online forums. However, the dependence of a user’s reputation on their history of activities seems to preclude any possibility of anonymity. We show that useful reputation information can, in fact, coexist with strong privacy guarantees. We introduce and formalize a novel...

In an unpredictable, heterogeneous world, intelligent agents depend on accurate social information; reputation, among the preeminent artifacts to transmit social evaluations, has been receiving growing attention by social scientists. A realistic description of reputation must include inaccurate information; in this paper, based on the distinction between image (agents’ believed evaluation of a ...

We introduce the opinion-based entity profiling task, understood as the automatic grouping of equivalent or very similar online opinions (both positive and negative) about an entity. This is a highly practical problem that arises in the context of online reputation management, but it has not been directly addressed by any Natural Language Processing evaluation campaign or specific benchmarking ...

Internet auction sites have evolved into markets where commodity goods such as electronics or DVDs are traded. Often several auctions for very similar (if not identical) items run simultaneously, and unit-demand bidders must adopt global multi-auction bidding strategies. Despite the increasing practical importance of such markets, there is relatively little theory on how unit-demand bidders sho...

its author's ability and erudition ; nor is it calculated to disgrace the shelf whereon repose the costly and elaborate publications of Haller and Plocquet. The present Treatise, rather comprehending all that has been written by others on the subject of consumptive diseases, than disclosing, original views of their history, pathology, or treatment, will certainly not detract from, the reputatio...

Reputation plays a major role in human societies, and it has been proposed as an explanation for the evolution of cooperation. While the majority of previous studies equates reputation with a transparent and complete history of players’ past decisions, in real life, reputations are often ambiguous and opaque. Using web-based experiments, we explore the extent to which opaque reputation works in...

The work of science teachers can be viewed from a variety of perspectives. In this article, teaching is seen as an activity in which teachers deliberate in the practical domain to decide on actions and goals. In the first part of the article, it is argued that, because practical reasoning is similar to scientific reasoning, a model of practical conceptual change can be developed that is analogo...

Information asymmetry is an important reason that causes external financing constraints. Because reputation has the function of signal transmission, a better reputation of an entrepreneur can reduce the degree of the firm information asymmetry and alleviate financing constraints of the firm. Based on the grouped sample of 94 listed companies of China from 2007 to 2009, this paper did empirical ...
