TL;DR: The most developed body of psychological literature showing evidence of significant differences in the reasoning styles of Chinese and "western" participants is that examining holistic vs analytic reasoning styles as mentioned in this paper, which may, hermeneutic scholarship suggests, challenge the universality of cognitive biases posited by the naturalness theory of religion.
Abstract: Is there any experimental evidence indicating there is something different or distinct about the psychology of ethnic Chinese? Might such differences challenge the purported universality of the cognitive biases outlined in succeeding chapters of this volume? The most developed body of psychological literature showing evidence of significant differences in the reasoning styles of Chinese and “Western” participants is that examining holistic vs analytic reasoning styles In this chapter we first introduce this body of research’s key terms and key empirical findings demonstrating Chinese preference for holistic reasoning Then, we connect particular elements of holistic reasoning to cultural logics operant in cornerstones of traditional Chinese thought—yin-yang theory, Doctrine of the Mean (zhong yong), wu wei, past-oriented reasoning (ie, assumptions of cyclical time), and pragmatism—that may, hermeneutic scholarship suggests, challenge the universality of cognitive biases posited by the naturalness theory of religion Finally, in our conclusion we attempt to draw a finer point on particular challenges holistic reasoning may present to particular components of the naturalness theory

TL;DR: In this paper , a novel single image dehazing method using a Type-2 membership function based similarity function matrix has been proposed to estimate the depth map and global atmospheric light of the observed hazy image.
Abstract: This article proposes a novel single image dehazing method using a Type-2 membership function based similarity function matrix. The proposed method estimates the depth map and global atmospheric light of the observed hazy image. The estimated depth map is further subjected to produce true scene transmission. Finally, the observed hazy image is dehazed by the atmospheric scattering model using scene transmission and global atmospheric light. The qualitative and quantitative comparisons of the proposed method have been presented with benchmarked state-of-the-art methods. The experiments have been extensively performed on benchmarked natural hazy images, MiddleBury Stereo dataset, REalistic Single Image DEhazing (RESIDE) dataset, RESIDE-$\beta$ dataset, and Stanford ImageNet dataset. The performance metrics used for comparison are peak signal to noise ratio and structural similarity index as quantitative measures; and lightness order error and naturalness image quality evaluator as qualitative measures. Moreover, the detection results using YOLOv2 on RESIDE-$\beta$ dataset have also been compared in terms of F1-score and area under curve measures. The qualitative and quantitative comparisons show that the proposed method outperforms others and dehazed images are restored effectively maintaining their naturalness.

TL;DR: The notion of naturalness as a component of QoO is formalized and quantitatively measures naturalness for well-known ontologies (UMLS, WordNet, OpenCyc) based on their concepts, IS-A relationships and semantic relationships.
Abstract: Ontologies, terminologies and vocabularies are popular repositories for collecting the terms used in a domain. It may be expected that in the future more such ontologies will be created for domain experts. However, there is increasing interest in making the language of experts understandable to casual users. For example, cancer patients often research their cases on the Web. The authors consider the problem of objectively evaluating the quality of ontologies (QoO). This article formalizes the notion of naturalness as a component of QoO and quantitatively measures naturalness for well-known ontologies (UMLS, WordNet, OpenCyc) based on their concepts, IS-A relationships and semantic relationships. To compute numeric values characterizing the naturalness of an ontology, this article defines appropriate metrics. As absolute numbers in such a pursuit are often meaningless, we concentrate on using relative naturalness metrics. That allows us to say that a certain ontology is relatively more natural than another one.

Finding broader or narrower concepts of a given concept is an important technique, which is recommended as a Web search strategy. According to Kalfoglou & Hu (2006), application ontologies are converging with the Web. Thus the knowledge provided by ontologies should be filtered dynamically by understanding the needs of Web users. There are several well-known ontologies, which many researchers have used and referenced, such as UMLS, WordNet and OpenCyc. Some researchers have presented modified or enriched ontological models by adding new types and trimming some detailed relationships from existing ontologies (Stone et al., 2004). On the other hand, research that investigates these ontologies not only from the view point of experts but also from the perspective of casual users is rare. Assessing difficulties in understanding and using ontologies for emerging user communities on the Semantic Web should be conducted as a stage of implementing the Semantic Web (Finin et al., 2007). In his original work on ontologies, Gruber (1993) stressed that ontologies are about knowledge sharing. We raise the question whether existing ontologies are constructed so that they may succeed at knowledge sharing. Zeng et al. (2005) showed that communication through terminologies can be significantly facilitated if words labeling concepts are comprehensible to users. Finding concepts which are likely to be recognized by users is a trend in ontology engineering, which is different from the traditional approach of building terminologies understandable mainly by experts of a domain. We are focusing on an ontology’s role, that is, knowledge sharing supported by an explicit specification of a conceptualization. The key idea of naturalness is based on the need for making terminologies understandable, as described in previous research (An et al., 2006). Some researchers (Staab and Maedche, 2000) have made efforts in making explicit the meaning of some semantic relationships in the form of axioms. However, this declarative knowledge with universal truths about concepts cannot provide answers for all the forms of knowledge inquiries (Mizoguchi, 2004). It is widely assumed that ontologies represent information in a form that is at least similar to how human knowledge is represented (Smith, 1982). Note that the distinction between primitive and defined concepts (Baneyx et al., 2005) is not employed in this research. It is easy to give precise definitions in mathematically-oriented domains. However, in real world applications this is often not the case. To many researchers, an ontology concept is a meaningless label, unless it is given a definition. However, any definition itself will contain logical symbols and other labels. Logical symbols do not cause a problem because they are domain independent. However, how can the defining labels themselves be defined? This leads to an infinite regression or circular definitions. Thus, we assume that, at some level, labels have to be understandable by being known to the recipient (program or human). As there are labels that are better known, what we call “more natural,” and labels that are less well known to humans, we prefer to use the more natural labels even for programs. We note that the meaning and the naturalness of concepts are orthogonal factors, as will be explained in more detail below. The author of a document usually has very little choice concerning the meaning he needs to get across. However, he can choose the most natural term for a specific meaning. In related work about the quality of ontologies, Ram & Park (2004) have focused on semantic interoperability. To enhance the semantics of ontologies, a methodology and analysis have been presented in (Supekar et al., 2004; Brachman, 1992). The ontologies that these researchers presented are domain-specific, so the sizes of the ontologies used are relatively small. In a broader view, some existing ontologies are described in (Noy & Hafner, 1997), however, numeric values and classifications of the ontologies are discussed without being supported by a mathematical model. 16 more pages are available in the full version of this document, which may be purchased using the \"Add to Cart\" button on the product's webpage: www.igi-global.com/article/formal-approach-evaluatingmedical-ontology/38941?camid=4v1 This title is available in InfoSci-Journals, InfoSci-Journal Disciplines Medicine, Healthcare, and Life Science.

TL;DR: In this paper, a fine-grained style control on the transformer-based text-to-speech synthesis (TransformerTTS) system is proposed by extracting a time sequence of local style tokens (LST) from the reference speech.
Abstract: In this paper, we present a novel architecture to realize fine-grained style control on the transformer-based text-to-speech synthesis (TransformerTTS). Specifically, we model the speaking style by extracting a time sequence of local style tokens (LST) from the reference speech. The existing content encoder in TransformerTTS is then replaced by our designed cross-attention blocks for fusion and alignment between content and style. As the fusion is performed along with the skip connection, our cross-attention block provides a good inductive bias to gradually infuse the phoneme representation with a given style. Additionally, we prevent the style embedding from encoding linguistic content by randomly truncating LST during training and using wav2vec 2.0 features. Experiments show that with fine-grained style control, our system performs better in terms of naturalness, intelligibility, and style transferability. Our code and samples are publicly available.
