Book Description Linked Data (LD) is a well-established standard for publishing and managing structured information on the Web, gathering and bridging together knowledge from different scientific and commercial domains. Queries over large scale (petabyte) data bases often mean waiting overnight for a result to come back. Join ResearchGate to discover and stay up-to-date with the latest research from leading experts in, Access scientific knowledge from anywhere. Massive simulations and arrays of sensing devices, in combination with increasing computing resources, have generated large, complex, high-dimensional datasets used to study phenomena across numerous fields of study. Visual Exploration. Hence, systems should provide, quirement of modern systems is to effectively support, Apart from the aforementioned requirements, modern systems must also, tomize the exploration experience based on her preferences and the individual, requirements of each examined task. They restrict themselves to dealing with, tional data management and visual explorations techniques. The ever-growing volume of data and its importance for business make data visualization an essential part of business strategy for many companies.. Data visualization tools are of great importance for the exploration and the analysis of Linked Data (LD) datasets. Many conventional data visualization methods are often used. F, new data constantly arrive (e.g., on a daily/hourly basis); in other cases, data. A questionnaire was distributed to participants in order to gather qualitative feedback on the prototype application after a set of tasks were completed. All of this often requires the service of a professional data visualization company. O termo Sistemas de Informação (SI), é utilizado para descrever sistemas que sejam automatizados. that only a small fragment of the input data to be accessed by the user. Usu-. Typically, each query focuses on a constantly shifting -- yet small -- range. Such time also means that potential avenues of exploration are ignored because the costs are perceived to be too high to run or even propose them. The main reason for this is the fact that researchers are accustomed to primary input devices, namely the keyboard and mouse to modify and interact with computer generated content. To recap, Big Data is the area that focuses on information sets too big to be handled using normal applications. Data visualization is an important component of many company approaches due to the growing information quantity and its significance to the company. First, the limitations of traditional visualization systems are outlined. The design of user interfaces for Linked Data, and more specifically interfaces that represent the data visually, play a central role in this respect. We detail the key requirements and design considerations for a visualization recommendation system. Thus, the study of the capabilities that each approach offers is crucial in supporting users to select the proper tool/technique based on their need. Data visualization enables users to perform a series, of analysis tasks that are not always possible with common data analysis, Major application domains for data visualization and analytics are, streams of data. As informações, por sua vez, são os dados de forma significativa e útil para as pessoas. Data Visualization is a major method which aids big data to get an absolute data perspective and as well the discovery of In these systems, which small parts of data are processed incrementally “following” users’ in-, Recall that, in exploration scenarios, a sequence of operations is performed, and, in most cases, each operation is driven by the previous one. Visualization plays an important role in exploring such datasets. (pre)processing (e.g., loading, indexing) the whole dataset. 1. In the Big Data era users that want to explore and acquire knowledge need first to become expert about the data processing part. The key innovation of DiNoDB is to piggyback on the batch processing phase the creation of metadata that DiNoDB exploits to expedite the interactive queries. Data visualization is discussed in a great num. Finally, we discuss the insights derived from the evaluation, and we point out possible future directions. The primary purpose of Big Data analysis is to make valuable and appropriate decisions; to achieve this purpose it needs a perfect visualization of Big Data. These approaches recommend the most suitable, . A complete list of LD tools has been created starting from previous surveys about Linked Data visualization and integrating newer tools published in research articles on the main academic web portals. Data visualization is the presentation of data in a pictorial or graphical format, and a data visualization tool is the software that generates this presentation. Modern systems should provide the user with the ability to cus-, ; e.g., screen resolution/size, available memory, allow the visual exploration of very large datasets, , where the graph is recursively decomposed into smaller sub-graphs, over large (unprocessed) datasets may be extremely costly, , where it is common that users attempt to find something interesting, processing and indexing techniques are used, in, the sets of data that are likely to be ac-, [49]. is the presentation of data in a pictorial or graphical for-, . related to data storage, querying, indexing, visual presentation, interaction, Given the above, modern visualization and exploration systems should, effectively and efficiently handle the follo, interaction with billion objects datasets, while maintaining the system. The results show that it is possible to use virtual reality technology to efficiently perform data retrieval tasks using 3D graph visualisations given that training is provided to users who are unfamiliar with virtual reality. In this paper, we present Slalom, an in-situ query engine that accommodates workload shifts by monitoring user access patterns. According to students’ feedback, the exploratory teaching program is useful for learning how to analyze large datasets and identify patterns that will improve any company’s and organization decision-making process. Exploring, visualizing and analyzing LD is a core task for a variety of users in numerous scenarios. In terms of scalability and readability, modern systems are required to process raw data faster than ever before.
