Current sentiment analysis techniques are good enough when predicting the opinion of a community of individuals over one item, but they may produce wrong or inaccurate results when several possibly correlated items are under consideration. We propose to exploit and adapt formalisms, methods, and tools from knowledge representation and voting theory to generalize sentiment analysis and obtain an...

The paper analyses the aggregation problem when the micro relations consist of multivariate specifications. We focus on a generalization of the model selection criterion proposed in the previous literature for discriminating between aggregate and disaggregate models. In addition, we extend the model selection problem in forecasting aggregate variables out of sample. Both the stationary and coin...

At least nine neurodegenerative diseases that are caused by the aggregation induced by long tracts of glutamine sequences have been identified. One such polyglutamine-containing protein is huntingtin, which is the primary factor responsible for Huntington's disease. Sedimentation velocity with fluorescence detection is applied to perform a comparative study of the aggregation of the huntingtin ...
