Due to insufficient sample sizes in national surveys, strikingly little is known about public opinion at the level of Congressional and state legislative districts in the United States. As a result, there has been virtually no study of whether legislators accurately represent the will of their constituents on individual issues. This paper solves this problem by developing a multi-level regressi...

Key in spatial planning are opinion dynamics (the exchange of opinions between agents and the consecutive updates in opinions by individual agents). A number of possibly relevant factors that are commonly excluded in well-known models of opinion dynamics are peer pressure, localized opinion formation through isolation, and the reputation of the agents involved. We present a model of agents with...

Mining opinions expressed in the user generated content is a challenging yet practically very useful problem. This survey would cover various approaches and methodology used in Sentimen...

In the classical approach to digital topology (see e.g. [12] and [13]), graph theoretic tools are used for structuring Z, namely the well-known binary relations of 4-adjacency and 8-adjacency. But neither 4adjacency nor 8-adjacency itself allows an analogue of the Jordan curve theorem (cf. [9]) and, therefore, one has to use a combination of the two adjacencies. To overcome this disadvantage, a...
