Redundancy in Web-scale Information Extraction: Probabilistic Model and Experimental Results

In urban planning, land-use policies are commonly applied to reduce automobile travel and encourage active transport because land use is believed affect behavior. However, a debate about such effects continues in literature. Empirical studies differing context, methodology, geographic scale come different results. Although questioned of self-selection, the accumulated empirical evidence provide...

The dependently-typed lambda calculus (LF) supports use of meta-level binding in reasoning about bindings and hypotheticals in programming languages. That is, lambda expressions in LF can be used to model binders and hypothetical judgments depending on fixed-size contexts. However, because LF does not have a concept of variable-arity functions, a hypothetical judgment depending on a variable-si...

We present an extension of Horn-clause logic which can hypothetically add and delete tuples from a database. Such logics have been discussed in the literature , but their complexities and expressibilities have remained an open question. This paper examines two such logics in the function-free, predicate case. It is shown, in particular, that augmenting Horn-clause logic with hypothetical additi...

In antiquity we encounter a distinction of two types of hypothetical syllogisms. One type are the 'mixed hypothetical syllogisms'. The other type is the one to which the present paper is devoted. These arguments went by the name of 'wholly hypothetical syllogisms'. They were thought to make up a self-contained system of valid arguments. Their paradigm case consists of two conditionals as premis...

Contingent Valuation studies, in which respondents are presented with a hypothetical choice, can be prone to hypothetical bias as respondents could overstate their willingness to pay. The purpose of this paper is to present a method to detect hypothetical bias in the single bound dichotomous choice model. The method borrows the tools from the stochastic frontier model, as in the case of Hofler ...

As well as their role in contributing towards emissions reductions targets, it is increasingly relevant for policymakers to understand the contribution that renewable energy technologies make economy. Various methods have been used quantify impacts, such job counts, surveys and measures based on economic statistics. Economic modelling approaches other hand appear offer an ability both provide m...
