In this paper, we introduce a methodology for analyzing judgment opinions. We define a judgment opinion as consisting of a valence, a holder, and a topic. We decompose the task of opinion analysis into four parts: 1) recognizing the opinion; 2) identifying the valence; 3) identifying the holder; and 4) identifying the topic. In this paper, we address the first three parts and evaluate our metho...

Experts are asked to provide their advice in a situation of uncertainty. They adopt the decision maker’s utility function, but each has a potentially different set of prior probabilities, and so does the decision maker. The decision maker and the experts maximize the minimal expected utility with respect to their sets of priors. We show that a natural Pareto condition is equivalent to the exist...

We propose an opinion model based on agents located at the vertices of a regular lattice. Each agent has an independent opinion (among an arbitrary, but fixed, number of choices) and its own degree of conviction. The latter changes every time two agents which have different opinions interact with each other. The dynamics leads to size distributions of clusters (made up of agents which have the ...

Reputation is generally defined as the opinion of a group on an aspect of a thing. This paper presents a reputation model that follows a probabilistic modelling of opinions based on three main concepts: (1) the value of an opinion decays with time, (2) the reputation of the opinion source impacts the reliability of the opinion, and (3) the certainty of the opinion impacts its weight with respec...

This paper deals with the composition of multi-member decision making bodies (committees) on the basis of fuzzy individual preference relations over candidates. The methods discussed are basically extensions of the principles of optimal representation as spelled out by Chamberlin and Courant. Since these principles are defined for nonfuzzy individual preference rankings, we focus primarily on t...

Instead of studying the properties of social relationship from an objective view, in this paper, we focus on individuals’ subjective and asymmetric opinions on their interrelationships. Inspired by the theories from sociolinguistics, we investigate two individuals’ opinions on their interrelationship with their interactive language features. Eliminating the difference of personal language style...

one of the most important issues in the occultation age that has been discussed by islamic jurists is whether the implementation of hudod punishment is allowed during the occultation age of infallible imam or not. the jurists have different opinions about this issue that we could generally categorize such opinions into three groups. the majority of jurists believe in the permissibility of perfo...

Implicit opinions are commonly seen in opinion-oriented documents, such as political editorials. Previous work have utilized opinion inference rules to detect implicit opinions evoked by events that positively/negatively affect entities (goodFor/badFor) to improve sentiment analysis for English text. Since people in different languages may express implicit opinions in different ways, in this wo...

With the Web 2.0 paradigm, a huge volume of Web content is generated by users at online forums, wikis, blogs, and social networks, among others. These user-contributed contents include numerous user opinions regarding products, services, or political issues. Among these user opinions, certain comparison opinions exist, reflecting customer preferences. Mining comparison opinions is useful as the...
