Clause-level sentiment classification algorithm is developed and applied to drug reviews on a discussion forum. The algorithm adopts a pure linguistic approach of computing the sentiment of a clause from the prior sentiment scores assigned to individual words, taking into consideration the grammatical dependency structure of the clause using the sentiment analysis rules. MetaMap, a medical reso...

Background As part of the EuroDRG project, researchers from eleven countries (i.e. Austria, England, Estonia, Finland, France, Germany, Ireland, Netherlands, Poland, Sweden, and Spain) compared how their Diagnosis-Related Groups (DRG) systems deal with cholecystectomy patients. The study aims to assist surgeons and national authorities to optimize their DRG systems.   Methods National or region...

JEL classification: C65, D63, D71, D81 Mathematics Subject Classification (2000): 91B16

In this study we analyzed the complete genomic sequences, except intron 1, and 2 regulatory regions of 6 common (ABO*A101, ABO*A201, ABO*B101, ABO*O01, ABO*O02, and ABO*O03) and 18 rare ABO alleles, 3 of which were new. This was done by phylogenetic analysis and correlating sequence data with the ABO phenotypes. The study revealed multiple polymorphisms in noncoding regions. The intron-based ph...

A treebank is an important language resource for supervised statistical parsers. The parser induces the grammatical properties of a language from this language resource and uses the model to parse unseen data automatically. Since developing such a resource is very time-consuming and tedious, one can take advantage of already extant resources by adapting them to a particular application. This re...

This experiment shows that Mathew Rabin’s (1993) fairness equilibrium is more descriptive than the relevant null hypothesis, that people’s generosity levels are innate. Participants treated others as they expected others to treat them. Prospective reciprocation creates path dependency in organizations’ cooperation levels. Organization member’s expectations of others’ willingness to cooperate ma...

This article updates Kelly and Bruestle (2011) by illustrating how publication trends in different subject categories in economics evolved from 2007 to 2013. Using data from RePEc we show that the largest increase in the relative share was for articles published in JEL category Q (“Agricultural and Natural Resource Economics, Environmental and Ecological Economics”) over this period. Furthermor...

We present a novel approach for relation classification, using a recursive neural network (RNN), based on the shortest path between two entities in a dependency graph. Previous works on RNN are based on constituencybased parsing because phrasal nodes in a parse tree can capture compositionality in a sentence. Compared with constituency-based parse trees, dependency graphs can represent relation...

This paper describes a semantic classification of Chinese and compares its performance with CKIP's word-class classification on the task of identifying the attributive dependency relation and the unmarked coordinative dependency relation of word bigrams made up from nouns, verbs, and adjectives.

Fiscal considerations may shift governmental priorities away from environmental concerns: Finance ministers face strong demand for public expenditures such as infrastructure investments but they are constrained by international tax competition. We develop a multi-region model of tax competition and resource extraction to assess the fiscal incentive of imposing a tax on carbon rather than on cap...
