SOASIS Chapter Meeting Southern Ohio Chapter American Society for Information Science Data Visualization Technology Ray

1. SOASIS Chapter Meeting • Southern Ohio Chapter • American Society for Information Science • Data Visualization Technology • Ray Daley • NEXIS Research and Development • 7:00 p.m. Thursday, May 18, 2000 • LEXIS-NEXIS, Dayton, OH Ray Daley, Data Visualization Technology, presentation at SOASIS

2. !WARNING! • Please note that this presentation was very dynamic in that we experienced many live demonstrations and several videos. • This powerpoint only contains simple screen shots it contain very little of the information presented verbally during the session. Thus, there are scant desciptions ofthe approaches, benefits, problems, principles, or other useful information about the field. Please refer to the following book for an excellent persective. Readings in Information Visualization : Using Vision to Think (Morgan Kaufmann Series in Interactive Technologies) by Stuart K. Card, Jock D. MacKinlay (Editor), Ben Shneiderman (Editor) Ray Daley, Data Visualization Technology, presentation at SOASIS

3. Agenda • Why, What, and How of Data Visualization • Scientific and Business Visualization • Visualization for Information Retrieval • View Based Searching/Faceted Classification • Discussion Ray Daley, Data Visualization Technology, presentation at SOASIS

4. Why Visualize “The real power comes from devising external aids that enhance cognitive abilities.” “The purpose of visualization is insight, not pictures. The main goals are discovery, decision making, and explanation.” “Information visualization is useful to the extent that it increases our ability to perform these and other cognitive activities.” Readings in Information Visualization : Using Vision to Think (Morgan Kaufmann Series in Interactive Technologies) by Stuart K. Card, Jock D. MacKinlay (Editor), Ben Shneiderman (Editor) Ray Daley, Data Visualization Technology, presentation at SOASIS

5. What is it “Visualization: The use of computer-supported, interactive, visual representations of data to amplify cognition.” “Scientific and Business Visualization: The use of Visualization on data that are usually physically based.” “Information Visualization: The use of visualization on abstract data.” Readings in Information Visualization : Using Vision to Think (Morgan Kaufmann Series in Interactive Technologies) by Stuart K. Card, Jock D. MacKinlay (Editor), Ben Shneiderman (Editor) Ray Daley, Data Visualization Technology, presentation at SOASIS

7. Scientific and Business Visualization • Uses: • To see what is too small or obscured. • To see what is too big to see. • To identify and communicate trends and patterns • Tools: • Maps, Charts, Graphs, Scatterplots, Zoom, Sort, Overview/Detail Ray Daley, Data Visualization Technology, presentation at SOASIS

27. Conclusion and Discussion • Visualization for scientific and business analysis and communication is obviously very successful. • What about Information Retrieval? • The primary task for today’s information retrieval end users is to find what they are looking for. • They type in a few words in a search box and go. • They browse one page of answers and try a new search. • Is there a Viz tool that will help them?
