Theories of counterfactuals agree on appealing to a relation comparative similarity, but disagree the quantificational force counterfactuals. We report two experiments testing predictions three main approaches: universal theories, homogeneity and single-world selection theories (plus supervaluations over functions). The critical cases in our experiment were constructed so as discriminate betwee...

In this paper we propose a novel probabilistic framework for document segmentation exploiting human perceptual recognition of text regions from complicated layouts. particular, conceptualize homogeneity as the Gestalt pattern displayed in regions, characterized by proximately and symmetrically arranged units with similar morphological texture features. We model local region connected component ...
