Here, using a community detection algorithm, potential tune families can be readily identified. However, the richer the information contained in the graph, the more difficult it is for the visualisation algorithms to operate successfully. Therefore, an approach is proposed which uses modified versions of the graph both to enhance the community detection results and, more importantly, restructure the graph, by creating a compound graph, to reveal the communities visually. Finally, the wider applicability of the technique is considered.","PeriodicalId":429883,"journal":{"name":"2019 23rd International Conference Information Visualisation (IV)","volume":"213 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131630059","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Content-based queries can be performed comparing features extracted from images, such as color, texture, and shape. In this paper we propose ways to delimit the region of interest to be visualized in the execution of queries by similarity in complex datasets. Limiting the amount of data to be visualized allows keeping the distribution of mapped data closer to the real distribution, besides allowing the application of more expensive computational methods for multidimensional projection. The proposed techniques were implemented in a prototype that allows visualizing only the region in which the query is being performed, mapping the data in three-dimensional spaces and allowing users to interact with them, being favored by human perception to improve the analysis and understanding of the data.","PeriodicalId":429883,"journal":{"name":"2019 23rd International Conference Information Visualisation (IV)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114400564","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It expresses a set of time stamps in the position on a plane. Although ChronoView offers high space efficiency, it can generate ambiguous representations. To solve this problem, glyphs have been exploited as ChronoView markers. This paper explains a user study conducted to investigate the effectiveness of the Star Glyph and Ring Glyph. The study shows that glyphs contribute to an accurate reading of temporal features. It also shows that Star Glyph and Ring Glyph have different features. It is clear that, whereas Ring Glyph dominates the time range reading, Star Glyph dominates the comparison of frequencies in the unit of time.","PeriodicalId":429883,"journal":{"name":"2019 23rd International Conference Information Visualisation (IV)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129440536","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This happens in varied areas such as trading on line, product ratings, support and use of services, and many more, comprising Distance Education. The ever increasing amount of such data can make analysis and extraction of meaningful information progressively harder, and sophisticated analysis techniques are to be used to extract added value from data. Many companies do collection and analysis of data with the purpose to develop their marketing strategies. In the field of education, and Distance Education in particular, data collected through online Learning Management Systems (LMSs) can provide a great resource, and a strong challenge, for the analysis of learning processes, the design of training paths, and the updating and personalization of learning environments. While, on the one hand, there is an increasing demand by educational institutions to measure, demonstrate, and improve the results achieved in distance learning, on the other hand the logic of traditional reporting included in LMS platforms does not satisfy that growing need. Learning Analytics is the answer to the need for optimization of learning through the techniques of analysis of data produced by learning processes, involving all stakeholders of the system. In this paper we show and discuss a brief state of the art of models of Learning Analytics presented in the literature.","PeriodicalId":429883,"journal":{"name":"2019 23rd International Conference Information Visualisation (IV)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129874813","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This is why data visualization and interaction is one of the quickest ways to facilitate investigation and communicate understanding. To perform visual analytics effectively at the textit{big data} scale it is crucial that we develop an integrated processing and visualization ecosystem. However, to date, in Large High-Resolution Display (LHRD) environments the worlds of data processing and visualization remain largely disconnected. In this paper, we propose a common architectural approach to enable integrated data processing and distributed visualization via the composition of discrete microservices. Each of these microservices provides a very specific clearly-defined function, such as analyzing data, creating a visualization, sharding data or providing a synchronization source. By defining common transport, data and API formats we enable the composition of these microservices from processing raw data through to analytics, visualization and rendering. This compositionality, inspired by successful data-driven visualization frameworks provides a common platform for immersive social visual analytics.","PeriodicalId":429883,"journal":{"name":"2019 23rd International Conference Information Visualisation (IV)","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126576209","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Time and space are two of these storytelling attributes which are commonly present in the story's structure. Thus, these should be considered in the creation process. Narrative Visualization is still a new field in Information Visualization research, and while there are guidelines for designing visualizations, specific ones for this new area are still lacking. Therefore, supported by previous research on broad recommendations for designing visualizations, we propose a specific set of guidelines to structure effective visual narratives divided into four decision categories: Intent, Spatio-temporal, Interaction, and Narrative Elements.","PeriodicalId":429883,"journal":{"name":"2019 23rd International Conference Information Visualisation (IV)","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127483790","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
