Abstract. In this article a use case is presented how a semantic network can be used to enrich the existing virtual exhibition “They Shared their Destiny. Women and the Cossacks’ Tragedy in Lienz 1945” about the fate of women during the Cossack tragedy in Lienz. By connecting via CIDOC CRM information about people, events, finds and places the goal was not only to make this information interoperable, but also to integrate the resulting knowledge graph into the exhibition, thus providing a further navigation level and enhancing the visitors’ experience.First, a short introduction to the existing exhibition and the presented project is given. In the second part, the scientific background of CIDOC CRM and its semantically enriched 3D content is outlined. In the third part the implementation and the project as a use case is described with respect to the data modelling and the integration of the semantic network into the 3-dimensional environment as well as the integration of spatial aspects and other internet resources. At the end, there is a summary with an outlook on future planned projects.

This paper describes the application of Semantic Networks for the detection of defects in images of metallic manufactured components in a situation where the number of available samples of defects is small, which is rather common in real practical environments. In order to overcome this shortage of data, the common approach is to use conventional data augmentation techniques. We resort to Generative Adversarial Networks (GANs) that have shown the capability to generate highly convincing samples of a specific class as a result of a game between a discriminator and a generator module. Here, we apply the GANs to generate samples of images of metallic manufactured components with specific defects, in order to improve training of Semantic Networks (specifically DeepLabV3+ and Pyramid Attention Network (PAN) networks) carrying out the defect detection and segmentation. Our process carries out the generation of defect images using the StyleGAN2 with the DiffAugment method, followed by a conventional data augmentation over the entire enriched dataset, achieving a large balanced dataset that allows robust training of the Semantic Network. We demonstrate the approach on a private dataset generated for an industrial client, where images are captured by an ad-hoc photometric-stereo image acquisition system, and a public dataset, the Northeastern University surface defect database (NEU). The proposed approach achieves an improvement of 7% and 6% in an intersection over union (IoU) measure of detection performance on each dataset over the conventional data augmentation.

The House of the Dead was repeatedly compared with the first part of Dante’s The Divine Comedy even in F.M. Dostoevsky’s lifetime. However, his contemporaries usually focused on general analogies, while later scholars paid more attention to the narrative features or individual reminiscences. This research studies the main aspects of the artistic structure of the Dante code, constructing the space of Hell in Dostoevsky’s novel. 1. The organization of space. Alexander Petrovich Goryanchikov, the narrator in The House of the Dead, recreates a three-dimensional image that resembles a gradually narrowing funnel: from a bird’s-eye view, where the prison is seen in its entirety, the focus slowly descends, passing to smaller objects, and finally reaching the “three boards”, which limit Goryanchikov’s personal space. The same principle is employed to construct the space of Hell in Dante’s poem. In The House of the Dead, there is another significant indication of the spatial affinity of Dante’s hell and Dostoevsky’s katorga – active imagery associated with cobwebs and spiders. In the centre of the system of images associated with the designated semantic network is the parade- major, the head of the fortress and the owner of the inmate web. 2. The character system as an element constituting the space of Hell. The character system of The House of the Dead follows the compositional principle of Divine Comedy, where sinners are located in different circles in accordance with their main passion. There are three circles in the prison: the first is formal, according to the court decision; the second is informal, internal, formed by crafts and occupations; the third represents Goryanchikov’s perspective as an exponent of human and humane judgment, which distinguishes another person’s moral state. 3. Torment. The House of the Dead demonstrate a hierarchy in describing the tortures, while freedom becomes a fundamental category to embody the most important motif of physical and moral torment connecting Dostoevsky’s novel with Dante’s experience. The bodily torment ceases to be only the torment of the body to become a pain of the soul, comparable to physical torment, so the soul suffers and burns. Hell as a moral topos was the key for Dostoevsky. In The House of the Dead, he chooses the same way as Dante in The Divine Comedy: vivid corporeality conveys an esoteric metaphor of moral suffering and deep inner movements of the soul.

There are many still unstudied aspects of the cultural history of early Quattrocento Rome, especially if we consider the years before 1443, the date of the more or less permanent re-entry into the civitas aeterna of Pope Eugenius IV. The nexus between the still ephemeral papacy and the emerging intellectual movement of Italian Renaissance humanism is one of these aspects. It is hoped that this study will shed some light on this problem by presenting a document that has hitherto not been completely edited: the original will of Cardinal Giordano Orsini. As we shall see, this important witness to the fifteenth century provides valuable information on many fronts, even on the structure of the old basilica of Saint Peter. The short introduction is in three parts. The first has a discussion of the cardinal's cultural milieu with a focus on the only contemporary treatise specifically about curial culture, Lapo da Castiglionchio's De curiae commodis. The second part addresses the textual history of the will as well as some misconceptions which have surrounded it. The third part contains a discussion of the will itself, along with some preliminary observations about what can be learned from the critical edition of the text here presented for the first time.

Cognitive science invokes semantic networks to explain diverse phenomena from reasoning to memory retrieval and creativity. While diverse approaches are available, researchers commonly assume a single underlying semantic network that is shared across individuals. Yet, semantic networks are considered the product of experience implying that individuals who make different experiences should possess different semantic networks. By studying differences between younger and older adults, we demonstrate that this is the case. Using a network analytic approach and diverse empirical data, we present converging evidence of age-related differences in semantic networks of groups and, for the first time, individuals. Specifically, semantic networks of older adults exhibited larger degrees, less clustering, and longer path lengths. Furthermore, the edge weight distributions of older adults individual networks exhibited significantly more skew and higher entropy across node pairs and, except for unrelated node pairs, less inter-individual agreement, suggesting that older adults networks are generally more distinct than younger adults networks. Our results challenge the common conception of a single semantic network shared by individuals and highlight the importance of individual differences in cognitive modeling. They also present valuable benchmarks to discern between theories of age-related changes in cognitive performance.

This chapter employs semantic network analysis to investigate the online database LexisNexis to study the dynamic co-evolutions of peace frames embedded in the news coverage from the Associated Press (AP--United States), Xinhua News Agency (XH--Mainland China), and South China Morning Post (SCMP—Hong Kong). From 1995 to 2014, while the war and harmony frames were relatively stable in AP and XH respectively, there was a trend toward convergence of the use of war frames between AP and XH. The convergence of semantic networks of coverage of peace in AP and XH may have left more room for SCPM to develop a unique peace frame, and the divergence of semantic networks of coverage of peace in AP and XH may lead SCPM to develop strategies of balancing the frames employed by AP and XH, thus creating a hybrid peace frame.

Norepinephrine and dopamine are both believed to affect signal-to-noise in the cerebral cortex. Dopaminergic agents appear to modulate semantic networks during indirect semantic priming, but do not appear to affect problem solving dependent on access to semantic networks. Noradrenergic agents, though, do affect semantic network dependent problem solving. We wished to examine whether noradrenergic agents affect indirect semantic priming. Subjects attended three sessions: one each after propranolol (40 mg) (noradrenergic antagonist), ephedrine (25 mg) (noradrenergic agonist), and placebo. During each session, closely related, distantly related, and unrelated pairs were presented. Reaction times for a lexical decision task on the target words (second word in the pair) were recorded. No decrease in indirect semantic priming occurred with ephedrine. Furthermore, across all three drugs, a main effect of semantic relatedness was found, but no main effect of drug, and no drug/semantic relatedness interaction effect. These findings suggest that noradrenergic agents, with these drugs and at these doses, do not affect indirect semantic priming with the potency of dopaminergic drugs at the doses previously studied. In the context of this previous work, this suggests that more automatic processes such as priming and more controlled searches of the lexical and semantic networks such as problem solving may be mediated, at least in part, by distinct mechanisms with differing effects of pharmacological modulation.

This article examines Riemann's discussion of the Harmonieschritte within the Skizze, locating that discussion within a nineteenth-century combinatorial tradition shaped by Riemann's conception of key. In this article, Riemann's Harmonieschritte is examined from three neo-Riemann standpoints. The first section offers a short introduction to the Harmonieschritte and examines neo-Riemann theory's embrace of these relationships, emphasizing the conflation of functional relations and root-interval transformations that this embrace has entailed. The second section discusses the development of Riemann's system of Harmonieschritte despite of neo-Riemannian theorists's acknowledgement of the system's susceptibility to interpretation as a group of transformations on the consonant triads. The third section focuses on tonal coherence, with particular interest on Riemann's recognition that Harmonieschritte might portend the sort of harmonic practice embraced by neo-Riemannians if left unchecked. The article concludes with a translation of Riemann's Systematik der Harmonieschritte, the summary of the complete “chromatic” family of triadic relations from the Skizze.

Depending on the demand of structure model in product configuration design, product types that can be configured are described and analyzed. Based on semantic networks as a kind of available knowledge representation form and Extend A/O tree, structural model of configurable product is put forward. The structural relation, assembly relation and configuring option relation are included, semantic relation among assembly parts is also expressed. Finaly, configurable node model is proposed.
