Analysis of Users’ Opinions about Reasons for Divorce
One of the most important issues related to knowledge discovery is the field of comment mining. Opinion mining is a tool through which the opinions of people who comment about a specific issue can be evaluated in order to achieve some interesting results. This is a subset of data mining. Opinion mining can be improved using the data mining algorithms. One of the important parts of opinion minin...
متن کاملIdentifying Collocations for Recognizing Opinions
Subjectivity in natural language refers to aspects of language used to express opinions and evaluations (Banfield, 1982; Wiebe, 1994). There are numerous applications for which knowledge of subjectivity is relevant, including genre detection, information extraction, and information retrieval. This paper shows promising results for a straightforward method of identifying collocational clues of s...
متن کاملDynamical model for competing opinions.
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 ...
متن کاملComputational Opinions
Existing approaches to knowledge representation and reasoning in the context of open systems either deal with “objective” knowledge or with beliefs. In contrast, there has been almost no research on the formal modelling of opinions, i.e., communicatively asserted ostensible beliefs. This is highly surprising, since opinions are in fact the only publicly visible kind of knowledge in open systems...
متن کاملDiverging Opinions
People often see the same evidence but draw opposite conclusions, becoming increasingly polarized over time. Prior discussions of this puzzle have focused on the failure of Bayesian reasoning or on the possibility of non-common priors. By contrast, we offer a model of diverging opinions in a Bayesian environment with common priors. In our model, people hold different private information and dis...
