Third International Conference on Coordinated and Multiple Views in Exploratory Visualization (CMV 2005)
No full textCMV 2005 is the third conference on Coordinated and Multiple Views in Exploratory Visualization. The aim of this conference is to bring together top researchers in the area, to stimulate discussion and debate ideas and future opportunities. This conference focuses on all aspects of multiple-view techniques including: multiform views, tight coupling, linked dynamic interaction, multiple views for interactive steering, and spreadsheet based visualisation techniques. The emphasis is on generating and manipulating multiple views and coordinating information between them. It is clear why users wish to explore, interact and interrogate their data. They are often faced with unknown data of huge proportions, with many variables and multiple dimensions. As such they are faced with an insurmountable comprehension task. Multiple views that are coordinated together can enhance and aid the user in this process. The first CMV conference was held in 2003. Over the last few years this field has developed and grown. In fact, many of the papers presented this year detail how multiple linked views can be used to solve a particular problem in a particular application domain. This is certainly an exciting time as we see CMV techniques and principles applied to solve real problems. But, there is still much work to be done. Not only discovering how to appropriately apply these ideas to new application domains, but to discover more effective CMV techniques and designs. One aspect of this research is the study and use of 'sharing things' for exploratory visualisation. Taking this simplistic view, we may learn from concepts such as sharing hardware devices in a computer system or managing, delegating roles in a human organization or collaborative support. During last year's conference we had an open discussion about the status of the area; it was generally agreed that we were reasonable at some aspects, such as manipulation (zoom, brush, etc.) and simultaneous exploration, but needed more effort into challenges such as: validation and evaluation of the effectiveness and appropriateness of the technique (e.g., whether two or more views are best, when one technique should be used over another), measuring quantities (especially measuring and comparing quantities over multiple windows), managing the whole visualization exploration, and integrating temporal data. It is encouraging that some of these challenges are being addressed in the papers of this volume. Indeed, this volume presents the current state of the art in CMV and allows the reader to discover more about this exciting and developing area
Message from the general and paper chairs
No full textThe IEEE Visual Analytics Science and Technology (VAST) Conference continues to develop and grow. Each year brings new researchers to the field and produces important advances in the theory and practice of visual analytics. VAST is now in its seventh year, and it is the third year as an IEEE Conference. The presented work demonstrates significant growth and maturation of the visual analytics community. We received 104 submissions and were able to accept 30 papers into the program. The conference program reflects the breadth of research in the visual analytics community. Paper sessions cover such areas as foundations of the analysis process; tree, network and social network analysis; support for sensemaking and collaborative analysis; visual computational analysis of multivariate data; space and time; and many applications of visual analytics capabilities such as in the biomedical field, risk management, text and document analysis. To select this year's program, an international program committee of 35 experts carefully considered and reviewed the papers through a two-cycle review process instituted this year. Each paper was assigned to a primary and a secondary reviewer from this committee. The primary and secondary reviewers assigned one more tertiary reviewer to each paper so that at least four reviews were provided for all papers. Based on these reviews, the paper chairs selected the papers conditionally first. The primary reviewer had to evaluate the revised papers carefully in the second review cycle. Finally, the paper chairs accepted 30 papers and organized the program sessions. We are grateful to the International Program Committee and the reviewers for their contributions to a successful review process
State of the Art: Coordinated & Multiple Views in Exploratory Visualization
Full text linkThe area of coordinated and multiple views has been steadily developing and maturing over the past fifteen years. Some may say that it is a "solved problem', while others argue that we are only just scratching the surface of the subject. Considering merely the CMV conference series, it is clear to see that in the early years researchers were concerned with models and techniques, while in latter years authors presented more work on how to apply these ideas to different domains. It is our view that there is still much research to be done, but the subject is changing and developing as a tool for visual analytics. This paper provides the "state of the art' of CMV, it describes areas that should be developed further and looks at what the future may hold for coordinated and multiple views
A Coordination Model for Exploratory Multi-View Visualization
Full text linkIn this paper, we present a coordination model for exploratory multi-view visualization. We base our work on current research in exploratory visualization and other disciplines. Our model is based on sharing abstract objects such as the visualization parameters of the dataflow model to achieve coordinated exploratory tasks in multiple views. This model describes how current coordinations in exploratory visualization work and allows novel coordinations to be constructed
Regular Spatial Separation for Exploratory Visualization
Full text linkThere are many well-used techniques in exploratory visualization that select, filter or highlight particular aspects of the visualization to gain a better understanding of the structure and makeup of the underlying information. Indeed, distortion techniques have been developed that deform and move different spatial elements of the representation allowing the user to view and investigate internal aspects of the visualization. But this distortion may cause the user to misunderstand the spatial structure and context of surrounding information and works better when the user knows what feature they are looking for. We believe that regular separation techniques, that separate and generate space round features or objects of interest clarifies the visual representations, are underused and that their use should be encouraged. We describe related research and literature, present some new methods, and classify the realizations by what type of separation is used and what information is being separated
Multiple view and multiform visualization
No full textVisualization is about discovery and understanding; the user wishes to gain a correct insight into the underlying information, to explore and analyze how different parts are related. Thus, presentation, exploration and explanation tools are used with manipulation and investigative techniques to display, discover and gain a `correct dissemination' of the information. Moreover, by displaying the information simultaneously in multiple ways the user is aided in their investigation. Such multiform techniques may be generated through various algorithms; we organize these methods according to how they apply to the individual stages of the dataflow paradigm. These multiforms may be displayed in separate windows. Multiple views are useful (1) to overcome misinterpretations and provide additional insight, (2) for scientific exploration tasks of relating, coupling and to aid the `drilling down' of information, and (3) to provide alternative viewpoints by expressing different user-interpretations of the same information. Finally, to use multiple views effectively they should be, among other things, easily created, automatically coupled to other views and dynamically manipulated
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
