Abstract:
In the field of aging design, obtaining elderly advantage data is a challenge. In this study, we developed a visualization tool using knowledge graph technology to assist designers in studying elderly advantages, promoting their application in design practice. First, brainstorming sessions and workshops were held to analyze the challenges of applying elderly advantages in design. Based on these challenges, the concept and functional design of an elderly advantages knowledge graph were proposed. Next, the elderly advantages knowledge graph was constructed by following these steps: (1) The KJ-AHP method was used to process raw data, making them structured and quantitative. (2) The ontology of the knowledge graph was reverse-engineered based on the functional requirements of the graph, allowing the construction of the knowledge graph model layer. (3) The processed data were applied to the knowledge graph ontology through AHP-ontology mapping rules, allowing the knowledge content construction. (4) The programming language Cypher was used for the functional verification of the elderly advantages knowledge graph, and a satisfaction survey was conducted through questionnaires to assess the verification process. The elderly advantages knowledge graph constructed in this study initially fulfilled the expected functions and was met with high satisfaction. The application of knowledge graph technology provides a new reference for advantage mining in the design field. Based on the innovative combination of KJ-AHP and knowledge graph technology, this study enhances the structuring and quantification of graph data, significantly facilitating designers’ understanding of data structures, clarifying data relationships, and expanding design thinking.

Abstract:
The subject of this study is the use of algebraic-logical modeling to develop adaptive distance learning systems. The proposed model is based on knowledge graphs, where each node represents a learning topic, and edges define logical and semantic relationships between subject areas. This approach enables the automation of determining the sequence of material acquisition and adapting the learning trajectory to the student's knowledge level. The objective of this work is to create a formal mathematical model of an adaptive learning process that ensures a personalized selection of learning topics and automatic adjustment of the learning trajectory based on student performance. The proposed model employs an ontological approach to structuring learning content and predicate algebra to define transition rules between topics. To achieve this goal, the following tasks were completed: an analysis of modern adaptive learning systems was conducted, a knowledge graph was developed to automate learning trajectories, an adaptive testing mechanism was implemented, and a software system for graph visualization was created. An essential aspect of the implementation is the use of WPF and QuickGraph for the interactive construction and processing of the educational trajectory. The methods considered include finite predicate algebra, graph theory, and object-oriented programming. Special attention is given to automated knowledge graph visualization and methods for adapting the learning process using logical equations. Results. An adaptive learning process model was obtained, allowing for a formal description of the structure of educational dependencies and ensuring the automatic selection of subsequent topics based on the student’s knowledge level. A software system for constructing and visualizing a knowledge graph in .NET (WPF) was implemented. The proposed approach provides learning process personalization, automated testing, and student progress analysis. The conclusions highlight the advantages of the developed model, including its integration into modern distance learning platforms and its potential to improve learning efficiency through dynamic testing and educational trajectory analysis.

Abstract:
Within a business environment, where the fast and reliable access to knowledge is a key success factor, an efficient handling of the organizational knowledge is crucial. Therefore the need for methods and techniques, which allow to structure and maintain complex knowledge bases according to the requirements emerging from the daily work have a high priority. This article provides a business process oriented approach to structure organizational knowledge and information bases. The approach was developed within applied research in the industrial, service and administrative sector. Following this approach, three different types of knowledge structures and their visualization have been developed by the Fraunhofer IPK and are currently applied and tested in organizations. Beside the approach itself, these three types of knowledge structure and the cases of application shall be introduced here.

Abstract:
Objectives to determine the main types of structuring information of navigation systems in medical organizations of the Russian Federation and evaluate their compliance with the principles of lean production.
 Material and methods. A structural analysis of the types of information presentation in navigation systems was based on the publications selected from the E-library, Medline, Scopus, PubMed and the Cochrane Library databases. The research process included the use of research methods for law, historical, descriptive-analytical methods, content analysis.
 Results. The structuring of navigation information can be done according to numerological, architectural, routing, alphabetical, structural, functional and combined principles. The optimal choice of the principle of organizing information should depend on how detailed the navigation system is, on the analysis of the architectural solutions used for a medical organization and on the calculation of navigation objects. It is possible to increase the efficiency of structuring navigational information using an appropriate color scheme, infographic and compositional solutions. When improving the navigation systems of medical institutions as a part of lean hospital management, it is necessary to audit all available navigation elements to determine the principle of structuring the information.
 Conclusion. The effective visualization of a medical institution is the provision of clear and understandable navigational information. One of the most effective methods to systematize the navigation information is its structuring.

Abstract:
The article discusses the problem of visualization of complex multiparameter systems, defined by datasets on their structure, functional structure, and activity in the form of complex graphs and transition of traditional representation of the data acquired by graph mining to a compact image built by pictographic methods. In these situations, we propose using the Unified Graphic Visualization of Activity (UGVA) method for data concentration and structuring. The UGVA method allows coding in an anthropomorphic image of elements of graphs with data on structural and functional features of systems and overlaying these images with the data on the system’s activity using coloring and artifacts. The image can be composed in different ways: it can include the zone of integral evaluation parameters, segmented data axes of five types, and four types of symmetry. We describe the method of creating UGVA images, which consists of 13 stages: the parametric model is represented as a structural image that is converted to a basic image that is then detailed into the particular image by defining geometric parameters of the primitives and to the individualized image with the data about a particular object. We show how the individualized image can be overlaid with the operative data as color coding and artifacts and describe the principles of interpreting UGVA images. This allows solving tasks of evaluation, comparison, and monitoring of complex multiparameter systems by showing the decision-maker an anthropomorphic image instead of the graph. We describe a case study of using the UGVA method for visualization of data about an educational process: curricula and graduate students, including the data mined from the university’s learning management system at the Siberian Federal University for students majoring in “informatics and computing”. The case study demonstrates all stages of image synthesis and examples of their interpretation for situation assessment, monitoring, and comparison of students and curricula. It allowed for finding problematic moments in learning for individual students and their entire group by analyzing the development of their competence profiles and formulating recommendations for further learning. The effectiveness of the resulting images is compared to the other approaches: elastic maps and Chernoff faces. We discuss using graph mining to generate learning problems in order to lessen the workload of gathering raw data for the UGVA method and provide general recommendations for using the UGVA method based on our experience of supporting decision making.

Abstract:
The accelerating evolution of scientific terms connected with 4P-medicine terminology and a need to track this process has led to the development of new methods of analysis and visualization of unstructured information. We built a collection of terms especially extracted from the PubMed database. Statistical analysis showed the temporal dynamics of the formation of derivatives and significant collocations of medical terms. We proposed special linguistic constructs such as megatokens for combining cross-lingual terms into a common semantic field. To build a cyberspace of terms, we used modern visualization technologies. The proposed approaches can help solve the problem of structuring multilingual heterogeneous information. The purpose of the article is to identify trends in the development of terminology in 4P-medicine.

Abstract:
Visualization is often defined as the act or process of making something visible. MacEachren and Ganter (1990) have argued for an expanded definition of cartographic visualization that emphasizes the role of the map-reader’s cognitive processes and schemata when creating visual representations. Cartographic visualization in this sense requires both the designer and the user to structure information and identify salient patterns. Processes of pattern identification and structuring are what help to provide insight in exploratory analysis. Pattern identification and information structuring need not, however, be limited to the visual realm. The use of haptic (both tactual and kinesthetic) information for representing geographic phenomena has been given limited attention as a method for exploring data, due to the difficulty of implementing such methods. However, advances in virtual reality technologies may soon make it possible to implement these variables in a system that creates exploratory geographic virtual environments. This paper explores those haptic variables that might be used to create such representations, and develops a haptic variable syntax for the representation of geographic information based on a logical analysis of the physiological properties of haptic sensation.

Abstract:
This article explores the idea of knowledge modeling as defined at the Florida Institute for Human and Machine Cognition. The notion of knowledge modeling is described to illustrate a particular method by which concept maps might be employed to create a useful structure and organization of other information and knowledge resources. Knowledge model structuring and navigational schemes afforded by the approach are described and illustrated. An example of a knowledge model pertaining to weather forecasting on the Gulf coast of the United States is presented to illustrate these ideas. Examples of how information visualization techniques have been and might be applied to the knowledge modeling scheme are discussed. Ideas pertaining to how knowledge models might serve as learning resources are briefly presented throughout. The article concludes with additional discourse regarding specific ways in which the knowledge modeling approach might be employed to create, present, and organize effective electronic learning resources.

Abstract:
Drawing on ethnomethodology and conversation analysis, I examine a lesson for Japanese nursery rhymes as an activity in which the culture of a particular expression is reproduced. More precisely, I investigate the way in which the singing voice becomes the object of instruction in a lesson and the object is visually structured by gesticulating the singing voice, thereby identifying the mechanisms of a lesson that produce better singing. To this end, the analysis focuses on (1) the sequential characteristics of a vocal lesson, (2) the use of the body configuration to demonstrate the singing voice to be taught, (3) and the envisioning of the singing voice to make it accountable. Based on the presented analysis, this article specifies the ways in which the teacher can convey the invisible qualities of singing to their student, with particular attention to the visualization of the voice.

Abstract:
Cette thèse explore des approches de structuration automatique et semi-automatique pour les collections de contenus iconographiques patrimoniaux. La structuration et l'exploitation de tels contenus pourrait s'avérer bénéfique pour de nombreuses applications, du tourisme virtuel à un accès facilité pour les chercheurs et le grand public. Cependant, l'organisation "en silo" inhérente à ces collections entrave les approches de structuration automatique et toutes les applications subséquentes.La communauté de la vision par ordinateur a proposé de nombreuses méthodes automatiques pour l'indexation (et la structuration) de collections d'images à grande échelle. Exploitant l'aspect visuel des contenus, elles fonctionnent indépendamment des structures de métadonnées qui organisent principalement les collections patrimoniales, apparaissant ainsi comme une solution potentielle au problème de liage entre les structures uniques des différentes collections. Cependant, ces méthodes sont généralement entrainées sur de grands jeux d'images récentes ne reflétant pas la diversité visuelle des contenus patrimoniaux. Cette thèse vise à évaluer et à améliorer ces méthodes automatiques pour la structuration des contenus iconographiques patrimoniaux. Pour cela, cette thèse apporte trois différentes contributions avec l'objectif commun d'assurer une certaine explicabilité des méthodes évaluées et proposées, nécessaire pour justifier de leur pertinence et faciliter leur adaptation à de nouvelles acquisitions. La première contribution est une évaluation des approches automatiques de recherche d'images basée sur le contenu, confrontées aux différents types de données du patrimoine iconographique. Cette évaluation se concentre d'abord sur les descripteurs d'images de l'étape de recherche d'images, puis sur les méthodes de ré-ordonnancement qui réorganisent ensuite les images similaires en fonction d'un autre critère. Les approches les plus pertinentes peuvent alors être sélectionnées pour la suite tandis que celles qui ne le sont pas fournissent des informations inspirant notre deuxième contribution. La deuxième contribution consiste en trois nouvelles méthodes de ré-ordonnancement exploitant des informations spatiales plus ou moins globales pour réévaluer les liens de similarité visuelle créés par l'étape de recherche d'images. La première exploite les premières images retrouvées pour créer une scène 3D approximative dans laquelle les images retrouvées sont positionnées pour évaluer leur cohérence dans la scène. La deuxième simplifie la première avec une expansion de requête géométrique, c'est-à-dire en agrégeant des informations géométriques 2D issues des images récupérées pour encoder plus largement la géométrie de la scène sans la reconstruire (ce qui est couteux en temps de calcul). Enfin, la troisième exploite des informations de position plus globales, à l'échelle du jeu d'images, pour estimer la cohérence entre la similarité visuelle entre images et leur proximité spatiale. La troisième et dernière contribution est un processus semi-automatique de validation visuelle et de correction manuelle de la structuration d'une collection. Ce cadre exploite les approches automatiques les plus adaptées et une plateforme de visualisation basée sur une représentation en graphes. Nous utilisons plusieurs indices visuels pour orienter l'intervention manuelle de l'expert sur les zones impactantes. Cette approche semi-automatique guidée présente des avantages certains, car elle résout des erreurs de structuration qui échappent aux méthodes automatiques. Ces corrections étant ensuite largement diffusées dans toute la structure, l'améliorant globalement.Nous espérons que notre travail apportera quelques perspectives sur la structuration automatique de contenus iconographiques patrimoniaux par des approches basées sur le contenu, tout en ouvrant la porte à davantage de recherches sur la structuration semi-automatique guidée de collections d'images<br>This thesis explores automatic and semi-automatic structuring approaches for iconographic heritage contents collections. Indeed, exploiting such contents could prove beneficial for numerous applications. From virtual tourism to increased access for both researchers and the general public, structuring the collections would increase their accessibility and their use. However, the inherent "in silo" organization of those collections, each with their unique organization system hinders automatic structuring approaches and all subsequent applications. The computer vision community has proposed numerous automatic methods for indexing (and structuring) image collections at large scale. Exploiting the visual aspect of the contents, they are not impacted by the differences in metadata structures that mainly organize heritage collections, thus appearing as a potential solution to the problem of linking together unique data structures. However, those methods are trained on large, recent datasets, that do not reflect the visual diversity of iconographic heritage contents. This thesis aims at evaluating and exploiting those automatic methods for iconographic heritage contents structuring.To this end, this thesis proposes three distinct contributions with the common goal of ensuring a certain level of interpretability for the methods that are both evaluated and proposed. This interpretability is necessary to justify their efficiency to deal with such complex data but also to understand how to adapt them to new and different content. The first contribution of this thesis is an evaluation of existing state-of-the-art automatic content-based image retrieval (CBIR) approaches when faced with the different types of data composing iconographic heritage. This evaluation focuses first on image descriptors paramount for the image retrieval step and second, on re-ranking methods that re-order similar images after a first retrieval step based on another criterion. The most relevant approaches can then be selected for further use while the non-relevant ones provide insights for our second contribution. The second contribution consists of three novel re-ranking methods exploiting a more or less global spatial information to re-evaluate the relevance of visual similarity links created by the CBIR step. The first one exploits the first retrieved images to create an approximate 3D scene of the scene in which retrieved images are positioned to evaluate their coherence in the scene. The second one simplifies the first while extending the classical geometric verification setting by performing geometric query expansion, that is aggregating 2D geometric information from retrieved images to encode more largely the scene's geometry without the costly step of 3D scene creation. Finally, the third one exploits a more global location information, at dataset-level, to estimate the coherence of the visual similarity between images with regard to their spatial proximity. The third and final contribution is a framework for semi-automatic visual validation and manual correction of a collection's structuring. This framework exploits on one side the most suited automatic approaches evaluated or proposed earlier, and on the other side a graph-based visualization platform. We exploit several visual clues to focus the expert's manual intervention on impacting areas. We show that this guided semi-automatic approach has merits in terms of performance as it solves mistakes in the structuring that automatic methods can not, these corrections being then largely diffused throughout the structure, improving it even more globally.We hope our work will provide some first insights on automatically structuring heritage iconographic content with content-based approaches but also encourage further research on guided semi-automatic structuring of image collections

Abstract:
A graph consists of a set and a binary relation on that set. Each element of the set is a node of the graph, while each element of the binary relation is an edge of the graph that encodes a relationship between two nodes. Graph are pervasive in many areas of science, engineering, and the social sciences: servers on the Internet are connected, proteins interact in large biological systems, social networks encode the relationships between people, and functions call each other in a program. In these domains, the graphs can become very large, consisting of hundreds of thousands of nodes and millions of edges. Graph drawing approaches endeavour to place these nodes in two or three-dimensional space with the intention of fostering an understanding of the binary relation by a human being examining the image. However, many of these approaches to drawing do not exploit higher-level structures in the graph beyond the nodes and edges. Frequently, these structures can be exploited for drawing. As an example, consider a large computer network where nodes are servers and edges are connections between those servers. If a user would like understand how servers at UBC connect to the rest of the network, a drawing that accentuates the set of nodes representing those servers may be more helpful than an approach where all nodes are drawn in the same way. In a feature-based approach, features are subgraphs exploited for the purposes of drawing. We endeavour to depict not only the binary relation, but the high-level relationships between features. This thesis extensively explores a feature-based approach to graph vi sualization and demonstrates the viability of tools that aid in the visual ization of large graphs. Our contributions lie in presenting and evaluating novel techniques and algorithms for graph visualization. We implement five systems in order to empirically evaluate these techniques and algorithms, comparing them to previous approaches.

Abstract:
Information visualization can be valuable in a wide range of applications, it deals with abstract, non-spatial data and with the representation of data elements in a meaningful form irrespective of the size of the data, because sometimes visualization itself focuses on the certain key aspects of the data in the representation and thus it helps by providing ease for the goal oriented interpretation. Information visualization focuses on providing a spontaneous and deeper level of the understanding of the data. Research collaboration enhances sharing knowledge and also enhances an individual’s talent. New ideas are generated when knowledge is shared and transferred among each other. According to (He et al, 2009) Research collaboration has been considered as a phenomenon of growing importance for the researchers, also it should be encouraged and is considered to be a “good thing” among the researchers. The main purpose of this thesis work is to prepare a model for the competence profile visualization purpose. For this purpose the study of different visualization techniques that exist in the field of information visualization are discussed in this thesis work. The study and discussion about the visualization techniques motivates in selecting appropriate visualization techniques for the visualization of Ontology-based competence profiles for research collaboration purpose. A proof of concept is developed which shows how these visualization techniques are applied to visualize several components of competence profile.

Abstract:
Data analysis techniques can be useful in decision-making processes, when patterns of interest can indicate trends in specific domains. Such trends might support evaluation, definition of alternatives, or prediction of events. Currently, datasets have increased in size and complexity, posing challenges to modern hardware resources. In the case of large datasets that can be represented as graphs, issues of visualization and scalable processing are of current concern. Distributed frameworks are commonly used to deal with this data, but the deployment and the management of computational clusters can be complex, demanding technical and financial resources that can be prohibitive in several scenarios. Therefore, it is desirable to design efficient techniques for processing and visualization of large scale graphs that optimize hardware resources in a single computational node. In this course of action, we developed a visualization technique named StructMatrix to find interesting insights on real-life graphs. In addition, we proposed a graph processing framework M-Flash that used a novel, bimodal block processing strategy (BBP) to boost computation speed by minimizing I/O cost. Our results show that our visualization technique allows an efficient and interactive exploration of big graphs and our framework MFlash significantly outperformed all state-of-the-art approaches based on secondary memory. Our contributions have been validated in peer-review events demonstrating the potential of our finding in fostering the analytical possibilities related to large-graph data domains.<br>Técnicas de análise de dados podem ser úteis em processos de tomada de decisão, quando padrões de interesse indicam tendências em domínios específicos. Tais tendências podem auxiliar a avaliação, a definição de alternativas ou a predição de eventos. Atualmente, os conjuntos de dados têm aumentado em tamanho e complexidade, impondo desafios para recursos modernos de hardware. No caso de grandes conjuntos de dados que podem ser representados como grafos, aspectos de visualização e processamento escalável têm despertado interesse. Arcabouços distribuídos são comumente usados para lidar com esses dados, mas a implantação e o gerenciamento de clusters computacionais podem ser complexos, exigindo recursos técnicos e financeiros que podem ser proibitivos em vários cenários. Portanto é desejável conceber técnicas eficazes para o processamento e visualização de grafos em larga escala que otimizam recursos de hardware em um único nó computacional. Desse modo, este trabalho apresenta uma técnica de visualização chamada StructMatrix para identificar relacionamentos estruturais em grafos reais. Adicionalmente, foi proposta uma estratégia de processamento bimodal em blocos, denominada Bimodal Block Processing (BBP), que minimiza o custo de I/O para melhorar o desempenho do processamento. Essa estratégia foi incorporada a um arcabouço de processamento de grafos denominado M-Flash e desenvolvido durante a realização deste trabalho.Foram conduzidos experimentos a fim de avaliar as técnicas propostas. Os resultados mostraram que a técnica de visualização StructMatrix permitiu uma exploração eficiente e interativa de grandes grafos. Além disso, a avaliação do arcabouço M-Flash apresentou ganhos significativos sobre todas as abordagens baseadas em memória secundária do estado da arte. Ambas as contribuições foram validadas em eventos de revisão por pares, demonstrando o potencial analítico deste trabalho em domínios associados a grafos em larga escala.

Abstract:
Abstract High-power ultrashort pulse lasers (USPLs) represent a sustainable alternative for industrial surface processing. Laser Surface Texturing (LST) allows modification of surface properties such as mechanical, chemical or optical properties. The adoption of USPLs in industry will enable the surface functionalization of large 3D parts through the LST process. However, a real exploitation of USPLs still faces limitations related to high processing resolution, quality, productivity, and the need for expert knowledge in laser micro-structuring strategies. It is crucial to increase maturity, reliability and throughput of LST on a large scale, as well as to provide the industry with the necessary tools for selecting the suitable laser process for each specific application. Achieving these goals requires significant effort in data collection, which is costly in terms of processing times, results analysis and human resources. Additionally, the availability of software simulators for laser micro-structuring is limited, posing challenges for describing USPLs processes through numerical models and methods. In this context, Artificial Intelligence (AI) models represent a unique tool to enhance process understanding and results analysis, providing rapid prediction and visualization capabilities. However, developing AI-models requires vast amounts of data, which are not easily obtainable experimentally, but simulators can play a vital role in this aspect. We present a combined solution based on machine learning methods fed by synthetic data generated by LS-Plume® from LASEA for predicting femtosecond laser single beam-based grooves on stainless steel 316L. The methodology for developing such applications is described, and several regression models are compared. The analysis of metrics and prediction error demonstrates that leveraging the synergy between simulation tools and AI-models can be an effective strategy for training AI-models, thereby avoiding the need for a complete, systematic, experimental parameter sweep approach. Consequently, the improvement of numerical models is a valuable strategy for training AI-models that can boost the adoption of USPLs for laser micro-structuring on a large industrial scale.

Abstract:
The troops of the national guard of the Russian Federation are equipped with modern models of weapons, special equipment, Informatization tools, engineering weapons that have artificial intelligence in their composition are being developed, " etc., which causes an increase in the requirements for the quality of professional training of future officers. The increasing complexity of military professional activities, the avalanche-like increase in information, the need to develop the ability to quickly and accurately make and implement well-known and own engineering solutions in an unpredictable military environment demonstrates that the most important tasks of modern higher education are not only providing graduates with a system of fundamental and special knowledge and skills, but also developing their professional independence, and this led to the concept of engineering and creative potential in the list of professionally important qualities of an officer. To expedite a special mechanism system compact intense clarity through cognitive visualization of the educational material, thickening of educational knowledge through encoding, consolidation and structuring Principle of cognitive visualization stems from the psychological laws in accordance with which the efficiency of absorption is increased if visibility in training does not only illustrative, but also cognitive function, which leads to active inclusion, along with the left and right hemispheres of the student in the process of assimilation of information, based on the use of logical and semantic modeling, which contributes to the development of engineering and creative potential.

Abstract:
This article is devoted to the presentation of the semantic interoperability of research and scientific results through an ontological taxonomy. To achieve this, the principles of systematization and structuration of the scientific/research results in scientometrics databases have been analysed. We use the existing cognitive IT platform Polyhedron and extend it with an ontology-based information model as main contribution. As a proof-of-concept we have modelled two ontological graphs, “Development of a rational way for utilization of methane tank waste at LLC Vasylkivska poultry farm” and “Development a method for utilization of methane tank effluent”. Also, for a demonstration of the perspective of ontological systems for a systematization of research and scientific results, the “Hypothesis test system” ontological graph has created.
