With the emergence of tools for collaborative ontology engineering, more and more data about the creation process behind collaborative construction of ontologies is becoming available. Today, collaborative ontology engineering tools such as Collaborative Protégé offer rich and structured logs of changes, thereby opening up new challenges and opportunities to study and analyze the creation of collaboratively constructed ontologies. While there exists a plethora of visualization tools for ontologies, they have primarily been built to visualize aspects of the final product (the ontology) and not the collaborative processes behind construction (e.g. the changes made by contributors over time). To the best of the authors’ knowledge, there exists no ontology visualization tool today that focuses primarily on visualizing the history behind collaboratively constructed ontologies. Since the ontology engineering processes can influence the quality of the final ontology, they believe that visualizing process data represents an important stepping-stone towards better understanding of managing the collaborative construction of ontologies in the future. In this application paper, the authors present a tool – PragmatiX – which taps into structured change logs provided by tools such as Collaborative Protégé to visualize various pragmatic aspects of collaborative ontology engineering. The tool is aimed at managers and leaders of collaborative ontology engineering projects to help them in monitoring progress, in exploring issues and problems, and in tracking quality-related issues such as overrides and coordination among contributors. The paper makes the following contributions: (i) They present PragmatiX, a tool for visualizing the creation process behind collaboratively constructed ontologies (ii) the authors illustrate the functionality and generality of the tool by applying it to structured logs of changes of two large collaborative ontology-engineering projects and (iii) they conduct a heuristic evaluation of the tool with domain experts to uncover early design challenges and opportunities for improvement. Finally, the authors hope that this work sparks a new line of research on visualization tools for collaborative ontology engineering projects.

The present work is part of a research paper for which I extend my heartfelt thanks to Assoc. Prof. Dr. Valko Kanev. It examines some specifics of the artistic creation process that lead to the creation of one of the types of written student texts - the narration. Its variations - "narration by imagination" and "narration by set supports" are regulated in the new fifth grade curriculum. The requirements for writing a narration and the exemplary thematic curriculum of optional literature classes in the 7-tgrade have proven to be applicable in the literature education process.

High Frequency Trading (HFT), mainly based on high speed infrastructure, is a significant element of the trading industry. However, trading machines generate enormous quantities of trading messages that are difficult to explore for financial researchers and traders. Visualization tools of financial data usually focus on portfolio management and the analysis of the relationships between risk and return. Beside risk-return relationship, there are other aspects that attract financial researchers like liquidity and moments of flash crashes in the market. HFT researchers can extract these aspects from HFT data since it shows every detail of the market movement. In this paper, we present HFTViz, a visualization tool designed to help financial researchers explore the HFT dataset provided by NASDAQ exchange. HFTViz provides a comprehensive dashboard aimed at facilitate HFT data exploration. HFTViz contains two sections. It first proposes an overview of the market on a specific date. After selecting desired stocks from overview visualization to investigate in detail, HFTViz also provides a detailed view of the trading messages, the trading volumes and the liquidity measures. In a case study gathering five domain experts, we illustrate the usefulness of HFTViz.

In the essay “Conversation about Dante,” Mandelstam described logic, which he defined as the “realm of unexpectedness,” which is unlike any everyday logical construction. Based on the analysis of Mandelstam’s text, it is assumed that we are talking about a tropology that arose in the Middle Ages, the principles of which can be derived from studies of St. Augustine’s treatise De Dialectica and Petrus Сomestor’s Historia Scholastica. It is this triple commonwealth (Augustine – Comestor – Dante, read by Mandelstam) that creates the multilayered logical framework of the work. Augustine created a completely different dialectic than in classical antiquity. Augustine considers dialectics as an art of discussion and describes the real steps that contribute to the emergence of speech, which corresponds to Mandelstam’s concept of conversation. According to Augustine, at the basis of any speech, is a trope-turn. In the article, attention is drawn to the sound nature of creation process. This logic, used in explaining the creation of the world according to the logos/word (tropology), assumes that, at the basis of the speech act, there is no the word as a unit of speech, but the sound itself – the sound, which was considered initially equivocal (ambiguous). In the process of pronounciation, the sound could turn into its opposite and could change the meaning of speech if the context has been changed. Dante expressed the meaning of tropology in practice. Mandelstam wrote that he had chosen Dante for the conversation (between poet and poet) “because he is the greatest and indisputable master of reversible and reversing poetic substance.” Mandelstam saw Dante as the Descartes of metaphor.

Abstract The presented article is dealing with the new methods which are designated for data collection of mammals migrating across traffic networks. Nowadays, road construction and securing of older roads is usually accompanied by finding new solutions. Because of lack of collected data we have new opportunities how we can collect this input. The article below describes the most efficient method which is suitable for the model creation, process of creation and issues which are connected with the creation of simulations.

Statistical learning theory provides the foundation to applied machine learning, and its various successful applications in computer vision, natural language processing and other scientific domains. The theory, however, does not take into account the unique challenges of performing statistical learning in geospatial settings. For instance, it is well known that model errors cannot be assumed to be independent and identically distributed in geospatial (a.k.a. regionalized) variables due to spatial correlation; and trends caused by geophysical processes lead to covariate shifts between the domain where the model was trained and the domain where it will be applied, which in turn harm the use of classical learning methodologies that rely on random samples of the data. In this work, we introduce the geostatistical (transfer) learning problem, and illustrate the challenges of learning from geospatial data by assessing widely-used methods for estimating generalization error of learning models, under covariate shift and spatial correlation. Experiments with synthetic Gaussian process data as well as with real data from geophysical surveys in New Zealand indicate that none of the methods are adequate for model selection in a geospatial context. We provide general guidelines regarding the choice of these methods in practice while new methods are being actively researched.
