    Full text link
    The IEEE Visual Analytics Science and Technology (VAST) Symposium has held a contest each year since its inception in 2006. These events are designed to provide visual analytics researchers and developers with analytic challenges similar to those encountered by professional information analysts. The VAST contest has had an extended life outside of the symposium, however, as materials are being used in universities and other educational settings, either to help teachers of visual analytics-related classes or for student projects. We describe how we develop VAST contest datasets that results in products that can be used in different settings and review some specific examples of the adoption of the VAST contest materials in the classroom. The examples are drawn from graduate and undergraduate courses at Virginia Tech and from the Visual Analytics “Summer Camp ” run by the National Visualization and Analytics Center in 2008. We finish with a brief discussion on evaluation metrics for education

    Interactive visualization systems and data integration methods for supporting discovery in collections of scientific information

    Technological developments have been enabling additional sharing and reuse of scientific information. Current indexing methods support query-based search and filtering, however they do not support overviews and exploration. Due to these limitations of existing indexing methods, it is challenging to discover records and connections that relate information in new and potentially insightful ways. We developed prototype systems and computational methods for integrating collections from multiple sources within a domain into a single, unified graph data structure. Graph-theoretic measures and visualizations were then applied to identify relations and records that support discovery tasks. Three collections of molecular information were studied: (1) influenza protein sequences from the National Center for Biotechnology Information, (2) Open Notebook Science notebooks and databases from Drexel University and other academic chemical research laboratories, and (3) project data from drug discovery projects at Pfizer R&D. We designed methods for data integration within these collections. We then analyzed the integrated collections to design interactive visual tools and computational methods that could systematically identify relations and records that have a high potential to lead to novel discoveries in these areas. We conducted interviews with domain experts to evaluate the effectiveness of these designs. These studies demonstrate the feasibility of the new indexing methods to improve the discoverability of novel connections across multiple collections within a domain.Ph.D., Information Science -- Drexel University, 201

    Jigsaw meets Blue Iguanodon - The VAST 2007 Contest

    No full text
    This article describes our use of the Jigsaw system in working on the VAST 2007 Contest. Jigsaw provides multiple views of a document collection and the individual entities within those documents, with a particular focus on exposing connections between entities. We describe how we refined the identified entities in order to better facilitate Jigsaw’s use and how the different views helped us to uncover key parts of the underlying plot

    [À l'origine dans / Was originally part of : ThĂšses et mĂ©moires - FAS - DĂ©partement d'Ă©tudes anglaises]Des dinosaures sur papier : des notes « sur le terrain » comme on en trouve dans le Badlands de Robert Kroetsch passe en revue cette Ɠuvre postmoderne de 1975 portant sur une expĂ©dition palĂ©ontologique fictive prĂšs de la riviĂšre Red Deer, en Alberta, conformĂ©ment Ă  la rĂ©cente tendance Ă  exiger la vĂ©rification systĂ©matique des donnĂ©es Ă  la base des rĂ©cits mĂ©tafictifs historiographiques dans la littĂ©rature canadienne-anglaise. InspirĂ©e de l’exploration canonique qu’a effectuĂ©e John Livingston-Lowes des plus grands poĂšmes de Samuel Taylor Coleridge par le biais de la mine d’or du Gutch Memorandum Book dans The Road to Xanadu, cette thĂšse entreprend un nouveau type de recherche qui se dĂ©marque des archives conventionnelles et de la tradition documentaire. S’appuyant sur des documents holographes non publiĂ©s provenant de dĂ©pĂŽts d’archives situĂ©s au QuĂ©bec, en Ontario et en Alberta et Ă©crits par des collecteurs, des gĂ©ologues et des palĂ©ontologues de la Commission gĂ©ologique du Canada, ainsi que sur des notes « sur le terrain », des notes de recherche et des journaux personnels Ă©crits par Robert Kroetsch pendant la rĂ©daction de son roman Badlands, cet examen critique rĂ©vĂšle les strates sous-jacentes inĂ©dites d’une Ɠuvre de fiction particuliĂšre. Dans pratiquement toute fouille palĂ©ontologique, le retrait de ce qui enveloppe un spĂ©cimen rĂ©vĂšle souvent des donnĂ©es supplĂ©mentaires qui peuvent, si elles sont soigneusement interprĂ©tĂ©es, offrir des indices essentiels sur les environnements palĂ©ontologiques. Ainsi, un squelette de dinosaure est rarement retirĂ© d’une carriĂšre stĂ©rile dans son intĂ©gralitĂ©. Il en va de mĂȘme pour toute recherche sur un processus littĂ©raire. Aucun texte ne s’autosuffit. Comme Kroetsch s’est efforcĂ© de produire son rĂ©cit sous forme d’interrogation sur la crĂ©ation et la transmission des donnĂ©es historiques, particuliĂšrement grĂące Ă  des notes « sur le terrain », une vaste Ă©tude de ce « terrain » comprenant des intertextes de l’AntiquitĂ©, des sciences, de l’Histoire, de l’histoire populaire, de rĂ©cits de voyages et de la littĂ©rature canadienne et internationale est ici menĂ©e. On y fait librement rĂ©fĂ©rence Ă  des pĂ©riodes et Ă  des auteurs trĂšs diversifiĂ©s, allant de Thomas Jefferson et des tombelles Ă  Bruce Chatwin et sa peau de « brontosaure ». Évidemment, aucune entreprise interdisciplinaire du genre ne peut ĂȘtre exhaustive. Ce projet se veut plutĂŽt une vitrine littĂ©raire rĂ©unissant des curiositĂ©s autour d’une Ɠuvre principale, soit le Badlands de Robert Kroetsch. RĂ©duites Ă  leur plus simple expression, les notes « sur le terrain » constituent des messages destinĂ©s Ă  la postĂ©ritĂ©. En explorant trois thĂšmes principaux, cette thĂšse explique comment ces messages pourraient ĂȘtre transmis. « Saxa Loquuntur ! », ainsi intitulĂ© en rĂ©fĂ©rence Ă  l’analogie de Freud avec l’archĂ©ologie, traite des mĂ©taphores associĂ©es aux tĂ©moignages de la pierre ; « Good Jones » porte sur les façons dont la taxinomie peut combler le dĂ©sir d’un chercheur d’os de ne pas tomber dans l’oubli ; « Box 16 » suit une piste documentaire en parcourant les Ă©crits de Kroetsch pour reconstituer tant l’élaboration d’un roman que les notions de temps, d’espace et d’origine d’une Ɠuvre littĂ©raire.Paper Dinosaurs: Field Notes as Finds in Robert Kroetsch's Badlands revisits the 1975 postmodern novel about a fictionalized palaeontological expedition down Alberta's Red Deer River in light of recent calls for systematic investigation into the source materials of historiographic meta-fictions in anglophone Canadian literature. Inspired by John Livingston-Lowes' canonical dissection of the major poems of Samuel Taylor Coleridge, via the treasure trove of the Gutch Memorandum Book in The Road to Xanadu, this study undertakes a new process focused inquiry into the archive and into the documentary tradition. By excavating unpublished holograph materials from Quebec, Ontario, and Alberta repositories written by Geological Survey of Canada collectors, geologists, and palaeontologists, in addition to field-notes, research notes and diaries produced by Robert Kroetsch during the writing of Badlands, this critical examination reveals hitherto unseen strata underlying a particular work of fiction. In most any palaeontological dig the removal of overburden from a target specimen often exposes surprising ancillary data, which through careful interpretation may give vital clues to palaeo-enviromments. A dinosaur skeleton is rarely pried whole from a sterile quarry. Neither is any inquiry into literary process. No text exists unto itself. Because Kroetsch so self-consciously crafted his narrative as an interrogation of history generation and transmission – specifically via the written word in the vehicle of field-notes – this study surveys a broad field encompassing inter-texts from antiquity, science, history, popular history, travel writing, Canadian and World literatures. Recourse is freely made to widely divergent authors and periods from Thomas Jefferson and the barrow mounds to Bruce Chatwin and his "brontosaurus" skin. Of course no such inter-disciplinary enterprise can be exhaustive. Rather this project assembles a kind of literary cabinet of curiosities grouped around the principal specimen of Robert Kroetsch's Badlands. In their most reductive configuration, field notes are messages to posterity. Through three main themes this study explores how these messages may be conveyed: "Saxa Loquuntur!", so titled after Freud's archaeological analogy, investigates metaphors of stone speaking; "Good Jones" interrogates how taxonomy can be made to serve a bone collector's desire to be remembered; and finally "Box 16" follows a documentary trail into Kroetsch's papers to trace not only the construction of a novel but also notions of time and place, and authorship

    A Holmes and Doyle Bibliography, Volume 9: All Formats—Combined Alphabetical Listing

    Get PDF
    This bibliography is a work in progress. It attempts to update Ronald B. De Waal’s comprehensive bibliography, The Universal Sherlock Holmes, but does not claim to be exhaustive in content. New works are continually discovered and added to this bibliography. Readers and researchers are invited to suggest additional content. This volume contains all listings in all formats, arranged alphabetically by author or main entry. In other words, it combines the listings from Volume 1 (Monograph and Serial Titles), Volume 3 (Periodical Articles), and Volume 7 (Audio/Visual Materials) into a comprehensive bibliography. (There may be additional materials included in this list, e.g. duplicate items and items not yet fully edited.) As in the other volumes, coverage of this material begins around 1994, the final year covered by De Waal's bibliography, but may not yet be totally up-to-date (given the ongoing nature of this bibliography). It is hoped that other titles will be added at a later date. At present, this bibliography includes 12,594 items
