Subjectivity detection is a task of natural language processing that aims to remove ‘factual’ or ‘neutral’ content, i.e., objective text that does not contain any opinion, from online product reviews. Such a pre-processing step is crucial to increase the accuracy of sentiment analysis systems, as these are usually optimized for the binary classification task of distinguishing between positive and negative content. In this paper, we extend the extreme learning machine (ELM) paradigm to a novel framework that exploits the features of both Bayesian networks and fuzzy recurrent neural networks to perform subjectivity detection. In particular, Bayesian networks are used to build a network of connections among the hidden neurons of the conventional ELM configuration in order to capture dependencies in high-dimensional data. Next, a fuzzy recurrent neural network inherits the overall structure generated by the Bayesian networks to model temporal features in the predictor. Experimental results confirmed the ability of the proposed framework to deal with standard subjectivity detection problems and also proved its capacity to address portability across languages in translation tasks. 相似文献

Italian soccer clubs in the first division have individually sold broadcasting rights for their home matches, until new laws imposed pooling and joint-selling those rights through the league and established a mandatory sharing rule to redistribute revenues in order to improve on-the-pitch competitive balance (CB). This article compares the two institutional designs. While reducing revenue inequality, the new regime distorts allocative efficiency and informational rent appropriation, opens up costly ex post renegotiations and antitrust litigations, and does not improve CB. 相似文献

In the present work, an analytical characterization of painted plaster samples coming from ancient buildings dated back to 2nd cent. B.C., located in Licata (Sicily, Southern Italy), has been carried out. The investigation has been performed through different spectroscopic techniques: X-ray fluorescence (XRF) using an handheld energy-dispersive XRF analyzer, scanning electron microscopy equipped with an Energy Dispersive Spectrometry microanalysis detector (SEM-EDS) and Fourier transform infrared absorbance spectroscopy (FT-IR). The main goal is to identify the plaster and pigments material. In particular, the XRF investigation of surfaces is the first step for a preliminary elemental characterization. Then, through SEM-EDS measurements, a quantitative analysis of the chemical composition of the plaster and the pigmenting agents along with eventual components related to deterioration processes has been obtained. Finally, FT-IR absorbance spectra have proven to be a useful tool to investigate the molecular nature of the used materials. 相似文献

Many painted surfaces, not necessarily only those with a contemporary binding media, display high sensitivity to water. The resulting damage, including swelling, leaching out of some components, even partial solubility, may lead to a shrunken, impoverished, de-plasticized, more porous paint film. Different approaches to the cleaning of such surfaces have been developed throughout the years, as awareness of this sensitivity grew worldwide. Some deal with the proper physico-chemical conditions of the aqueous solutions, and others with the proper ways of delivering these solutions to the surface. The strategy proposed in this technical note is concerned with the latter, the application stage, and is based on the combined and simultaneous use of a device capable of delivering a constant, precise amount of the aqueous cleaning solution and a surgical micro-aspirator to immediately remove the soiled solution from the surface and speed up its drying. Also, using a different apparatus, non-polar solvents can be delivered, for cleaning surfaces contaminated by non-polar, more lipophilic soiling materials. 相似文献

Hosting sporting mega-events involve considerable investment in and significant engagement with local communities. This paper contributes to the burgeoning literature about sporting mega event’s socio-geographical impacts on tourism, employment, urban regeneration, and socio-economic and cultural benefits. Within the context of 2014 FIFA World Cup in Brazil, we assess, utilizing interview data from local communities, the impact of the construction of the 2014 World Cup’s opening venue, ‘Arena Corinthians’ soccer stadium, in Itaquera, as well as other infrastructure developments more widely in the East Zone of São Paulo. The results point to the diversity of opinions among the resident community about the real legacies resulting from this sport mega-event. 相似文献

SYNOPSISDoes work-family conflict influence parental behaviors and parenting-related emotional states? Through an experimental research approach, River and colleagues showed that work-family conflict influences both emotions and parental behaviors, but the effect is moderated by the quality of the intimate relationship. In this commentary, we offer an interpretation of the results congruent with the recent theoretical approaches that stress the need for a multisystem psycho-biological approach to studying the factors that regulate parenting behaviors. In this perspective, we provide complementary explanations of the observed results and suggest possible future directions for research on these topics. 相似文献

Over the last years, several studies have suggested a possible link between dyslexia and deficits in low-level visual processing (e.g., excessive crowding). At the same time, specially designed “dyslexia-friendly” fonts appeared on the market. This class of fonts presents two main features: the particular graphic characteristics of the letterform designed to avoid confusion between similarly shaped letters, and wider inter-letter and inter-word spacing to limit crowding. The literature testing the efficacy of “dyslexia-friendly” fonts in improving reading accuracy and increasing reading speed is controversial. We evaluated the impact of letterform (with vs. without dyslexia-friendly graphic features), inter-letter spacing (standard vs. increased), and inter-word spacing (standard vs. increased) on reading accuracy and speed. Two groups of 64 children each, with and without dyslexia, read aloud 8 equivalent texts. The data collected failed to show any effect from the letterform. As regards spacing, the data showed that reading speed is impaired by an increase in inter-letter spacing not combined with an adequate increase in inter-word spacing. 相似文献
