We explore the utility of a computational framework for social authority in dialogue, codified as utterance-level annotations. We first use these annotations at a macro level, compiling aggregate statistics and showing that the resulting features are predictive of group performance in a task-based dialogue. Then, at a micro level, we introduce the notion of an interaction pattern, a formulation...

Forecasting the unit cost of every product type in a factory is an important task. However, it is not easy to deal with the uncertainty of the unit cost. Fuzzy collaborative forecasting is a very effective treatment of the uncertainty in the distributed environment. This paper presents some linear fuzzy collaborative forecasting models to predict the unit cost of a product. In these models, the...

Financial news carry information about economical figures and indicators. However, these texts are mostly unstructured and consequently hard to be processed in an automatic way. In this paper, we present a representation formalism that supports a linguistic composition for machine learning tasks. We show an innovative approach to structuring financial texts by extracting principal indicators. C...

Using a novel semiparametric approach, we estimate household income uncertainties and characterize their dynamics over the last three decades. We find that household income uncertainties have risen significantly and persistently since early 1970s, a phenomenon squarely opposite to “Great Moderation” – the observed sharp decline of volatility in aggregate data. For example, family non-capital in...

SUOWA operators are a new family of aggregation functions that simultaneously generalize weighted means and OWA operators. Semi-uninorms, which are an extension of uninorms by dispensing with the symmetry and associativity properties, play a fundamental role in their definition. In this paper we show several procedures to construct semi-uninorms. The first one allows us to obtain continuous sem...

Research suggests that the costs of international conflict (e.g. casualties) alter public opinion, executive approval and policy positions of elected officials. However, do casualties affect voting in terms of aggregate outcomes and individual vote choices? This article examines how casualties from interstate conflicts affect voter behaviour, specifically incumbent vote share. Using the investm...

Given a set of conflicting arguments, there can exist multiple plausible opinions about which arguments should be accepted, rejected, or deemed undecided. Recent work explored some operators for deciding how multiple such judgments should be aggregated. Here, we generalize this line of study by introducing a family of operators called interval aggregation methods, which contain existing operato...

For the first time we demonstrate skew of less than 0.25ps / m across a 10-wide graded index multimode fiber ribbon. This sub-picosecond skew extends practical applications of multimode fiber ribbon to include synchronous parallel transmission with an aggregate data-rate distance product of greater than 10Gb / s ⋅km .

Seller reputation is an important asset because buyers often choose sellers on the basis of their reputation. This is particularly true when the quality of the good or service transacted is hard to measure and the parties cannot perfectly contract on the outcome of the transaction. As a consequence, the seller will be mindful of building and maintaining a good reputation through the information...
