    • About This Survey This evaluation is about finding useful, usable tools that will help unlock the story that data has to tell. The solutions have evolved, and so have our problems. Page 3 © 2008 Avenue A | Razorfish, Inc. All rights reserved.
    • About This Survey Looking for tools to • Develop taxonomy, controlled vocabulary, and metadata relationships • Prototype data so that designers can create meaningful interactive experiences • Provide non-technical business users with a way to visualize and verify data Page 4 © 2008 Avenue A | Razorfish, Inc. All rights reserved.
    • About This Survey Not evaluating • Tool integration • Data mapping, migration or conversion • Data formats or standards Page 5 © 2008 Avenue A | Razorfish, Inc. All rights reserved.

    • The problem 1999: We need metadata! Page 8 © 2008 Avenue A | Razorfish, Inc. All rights reserved. Photo by Kyle Flood
    • History: EW.com [1999] The Scenario •Multiple articles on the same movie •Predictable related data, such as: lead performers, release date, director, etc. Page 9 © 2008 Avenue A | Razorfish, Inc. All rights reserved.
    • History: EW.com [1999] Our Needs •Standardize keywords •Star Wars: Episode 1 - The Phantom Menace •Star Wars - Episode I: The Phantom Menace •Star Wars: The Phantom Menace •Apply related data with a single selection •Update once, publish to many pages •Expose rich data relationships Page 10 © 2008 Avenue A | Razorfish, Inc. All rights reserved.
    • History: EW.com [2000] Our Solution: Category Tool •Relational Database •Controlled Vocabulary •Hierarchical Page 11 © 2008 Avenue A | Razorfish, Inc. All rights reserved.
    • History: EW.com [2000] Our Solution: Category Tool •Structured category paths: •Movie > Product > Men in Black •Person > Individual > Will Smith •Relationship types: •Performance, lead •Director •Release Date Page 12 © 2008 Avenue A | Razorfish, Inc. All rights reserved.
    • History: EW.com [2000] Our Solution: Category Tool •Relationships between categories: •{Tom DiCillo} Director of {Double Whammy} Page 13 © 2008 Avenue A | Razorfish, Inc. All rights reserved.
    • History: EW.com [2000] Our Solution: Category Tool •Differentiation: • Movie > TheGreen Mile • Book > The Green Mile • Movie > Cats & Dogs • Movie > The Truth About Cats & Dogs Page 14 © 2008 Avenue A | Razorfish, Inc. All rights reserved.
    • History: TOPICS [2003] The Next Generation Requirements •Scalable •Based on industry standard formats •Support all existing data needs •Support data needs that the old system couldn’t handle •Reliable Page 15 © 2008 Avenue A | Razorfish, Inc. All rights reserved.
    • History: TOPICS [2004] Our Solution •Opted for RDF & OWL •No commercial tools suited us •Wrote specs and built the tool ourselves Page 16 © 2008 Avenue A | Razorfish, Inc. All rights reserved.
    • History: TOPICS [2005] Our Solution – Live! •Pilot system rolled out in early 2005 •Three new sites launched in 6 weeks Success? •Sort of… Page 17 © 2008 Avenue A | Razorfish, Inc. All rights reserved.
    • History: TOPICS [2005] Further problems •Awkward integration with an older CMS •New data not published in real time •We had to provide all the tool support •The editors found it complicated to use Page 18 © 2008 Avenue A | Razorfish, Inc. All rights reserved.
    • History: TOPICS [2005] Further problems: Usability •Search •Browse •Preview •QA Page 19 © 2008 Avenue A | Razorfish, Inc. All rights reserved.
    • The problem 2008: Make sense of this metadata! Page 20 © 2008 Avenue A | Razorfish, Inc. All rights reserved. Photo by Kyle Flood
    • Current needs [2007] New projects, familiar problems: •Taxonomy, metadata, controlled vocabulary, and relationships •Envision how this data will translate into a website Page 21 © 2008 Avenue A | Razorfish, Inc. All rights reserved.
    • A recent problem set [2008] A colleague posed this problem: •Articles related to ideas, people, organizations •Each concept is related to other articles •Design should demonstrate relationships •We need to expose the relationships so we can solve the design problems Page 22 © 2008 Avenue A | Razorfish, Inc. All rights reserved.
    • A recent problem set [2008] Key Question How do we… •explore the nature and scope of these relationships… •and design a meaningful visualization of the data landscape… •before we’ve chosen and implemented a data management solution? Page 23 © 2008 Avenue A | Razorfish, Inc. All rights reserved.
    • Recap • 1999 – Need Metadata! • 2000 – Relational Database Categories • 2003 – Pushed to its limits • 2004 – RDF/OWL homegrown tool • 2005 – Launched several new sites but… the UI dooms it to failure • 2008 – Need to Expose, Understand, Prototype & Share Metadata!

    • The solutions have evolved, and so have our problems. Page 25 © 2008 Avenue A | Razorfish, Inc. All rights reserved.
    • Survey: Tools available now Page 26 © 2008 Avenue A | Razorfish, Inc. All rights reserved. Photo by Craig Munro
    • Selection method Looking for tools that are • readily available • easy to start using • useful for the design process Page 27 © 2008 Avenue A | Razorfish, Inc. All rights reserved.

    • Thesaurus Tools Used to construct lists of hierarchical sets of data, employing a construction based on Broader Terms and Narrower Terms. MultiTes A.K.A. Semaphore Ontology Manger A.C.S TermTree WebChoir TCS-10 Page 29 © 2008 Avenue A | Razorfish, Inc. All rights reserved.
    • Thesaurus Tool: MultiTes • Viewed as a alphabetical list, except when looking at an individual term Page 30 © 2008 Avenue A | Razorfish, Inc. All rights reserved.
    • Thesaurus Tool: MultiTes • Provides many ways to perform each task Page 31 © 2008 Avenue A | Razorfish, Inc. All rights reserved.
    • Thesaurus Tool: MultiTes • Create relationships to existing terms by typing– faster but potentially less accurate • Probably the easiest of these tools to use Page 32 © 2008 Avenue A | Razorfish, Inc. All rights reserved.
    • Semaphore Ontology Manager • Originally designed as a thesaurus tool, added capability to manage classes and relationships • Awkward UI requires more steps for simple tasks Page 33 © 2008 Avenue A | Razorfish, Inc. All rights reserved.
    • A. C. S. Term Tree • In default mode, terms are displayed in both flat and tree mode Page 34 © 2008 Avenue A | Razorfish, Inc. All rights reserved.
    • WebChoir TCS-10 • Easier to use than some, though it looks more obscure • Easy to change levels Page 35 © 2008 Avenue A | Razorfish, Inc. All rights reserved.
    • Drawbacks of Thesaurus Tools • Require an abstract understanding of thesaurus type relationships that doesn’t really contribute to the design process • Limited support for other relationships • Moving terms from one level to another tends to be difficult • Lack robust visualization options Page 36 © 2008 Avenue A | Razorfish, Inc. All rights reserved.
    • Brainstorming Tools Used to quickly map concepts and terms. More visual and easier to add, remove and rearrange things rapidly, while working. Mindjet MindManager Bubbl.us FreeMind Page 37 © 2008 Avenue A | Razorfish, Inc. All rights reserved.
    • Brainstorming Tool: MindManager • Visual expression of hierarchy • Collapse branches for greater clarity Page 38 © 2008 Avenue A | Razorfish, Inc. All rights reserved.
    • Brainstorming Tool: MindManager • Visual cues guide user as they work with the terms Page 39 © 2008 Avenue A | Razorfish, Inc. All rights reserved.
    • Brainstorming Tool: MindManager • Other relationships become messy Page 40 © 2008 Avenue A | Razorfish, Inc. All rights reserved.
    • Bubbl.us • Online • Free • Sharable Page 41 © 2008 Avenue A | Razorfish, Inc. All rights reserved.
    • Freemind • Free • Easy • Less stylish Page 42 © 2008 Avenue A | Razorfish, Inc. All rights reserved.
    • Drawbacks of Brainstorming Tools • Not great for expressing non-hierarchical relationships • Becomes difficult to read when there are a large number of nodes Page 43 © 2008 Avenue A | Razorfish, Inc. All rights reserved.
    • Ontology Tools Used to capture metadata using semantic standards. More flexible and powerful in the types of relationships they can capture. SWOOP Altova SemanticWorks Protégé TopQuadrant TopBraid Composer Page 44 © 2008 Avenue A | Razorfish, Inc. All rights reserved.
    • Ontology Tool: SWOOP • Load or create data • Browse classes with properties & instances Page 45 © 2008 Avenue A | Razorfish, Inc. All rights reserved.
    • Ontology Tool: SWOOP • Browse instances & assertions Page 46 © 2008 Avenue A | Razorfish, Inc. All rights reserved.
    • Ontology Tool: SWOOP • “Flying the mother ship” view Page 47 © 2008 Avenue A | Razorfish, Inc. All rights reserved.
    • Altova Semantic Works • Cumbersome labels & UI Page 48 • No built in support for visualization © 2008 Avenue A | Razorfish, Inc. All rights reserved.
    • Protégé • Very easy to use for OWL editing Page 49 • Visualization requires GraphViz © 2008 Avenue A | Razorfish, Inc. All rights reserved.
    • TopQuadrant Top Braid • Very robust tool Page 50 © 2008 Avenue A | Razorfish, Inc. All rights reserved.
    • TopQuadrant Top Braid • Built in visualizations: Class Diagram Page 51 © 2008 Avenue A | Razorfish, Inc. All rights reserved.
    • TopQuadrant Top Braid • Built in visualizations: Graph Page 52 © 2008 Avenue A | Razorfish, Inc. All rights reserved.
    • Drawbacks of Ontology Tools • Required knowledge of the workings of RDF and OWL could be a barrier • Not enough of them have good, flexible visualization options Page 53 © 2008 Avenue A | Razorfish, Inc. All rights reserved.
    • Visualization Tools Used primarily for viewing and exploring data and relationships, not for creating or editing. RDF Gravity IBM ManyEyes OwlSight Wordmap Page 54 © 2008 Avenue A | Razorfish, Inc. All rights reserved.
    • Visualization Tool: RDF Gravity Page 55 • Load OWL or RDF file © 2008 Avenue A | Razorfish, Inc. All rights reserved.
    • Visualization Tool: RDF Gravity Page 56 • Show or Hide elements as needed © 2008 Avenue A | Razorfish, Inc. All rights reserved.
    • ManyEyes: Treemap Page 57 • Online, free, public data, spreadsheet © 2008 Avenue A | Razorfish, Inc. All rights reserved.
    • ManyEyes: Bubble Chart Page 58 • Online, free, public data, spreadsheet © 2008 Avenue A | Razorfish, Inc. All rights reserved.
    • OwlSight Page 59 • Online, free, similar to SWOOP © 2008 Avenue A | Razorfish, Inc. All rights reserved.
    • Wordmap Page 60 • Very simple taxonomy explorer © 2008 Avenue A | Razorfish, Inc. All rights reserved.
    • Drawbacks of Visualization Tools • Data has to be created elsewhere and imported • Most are not quite flexible enough to show a wide range of data relationships Page 61 © 2008 Avenue A | Razorfish, Inc. All rights reserved.
