What are Taxonomies? • Taxonomy: a classification of elements within a domain • Domain: a sphere of knowledge, influence, or activity • Classification: the operation of grouping elements and establishing relationships between them (or the product of that operation) • Relationships: a defined linkage between two elements • Element: an object or concept Using Taxonomies- Microsoft Knowledge Network Group
Where do Taxonomies Fit? Using Taxonomies- Microsoft Knowledge Network Group
What are Taxonomies Good For? • Taxonomies are applied to: • Items: (aka resources) individual pieces of information (documents, people, etc…) • By the use of: • Metadata: (aka properties, attributes) information describing types of data. • Which may or may not use values from a: • Vocabulary: selection of terms, classified or sorted • To create: • Content: an item and its associated metadata Using Taxonomies- Microsoft Knowledge Network Group
How Do You Build Taxonomies? • Determine scope of project • Boundaries will determine resources needed • Breadth and depth are both important dimensions • Obtain resource commitments • Project will require both high and low level support • If cross-organizational, even more critical Using Taxonomies- Microsoft Knowledge Network Group
First Steps • User needs survey to understand: • The content your users need to do their work • The ways your users access that conten • The context(s) in which your users function • Information audit to determine: • Where your existing content is • How that content is structured • Who is responsible for the content Using Taxonomies- Microsoft Knowledge Network Group
Sample Survey Questions MSWeb Redesign Information Goals/User Assessment Sheet: 1. List the top five most important information services/or products under your area that you think most employees need to know about? What is the business impact of employees not being aware of this information? 2. Are there additional services and/or information/products within your area that would benefit from increased exposure? Describe the potential business value from employees having a better awareness or understanding of this information. 3. What types of content/information do you think is missing from MSWeb? Why is it important that this…. Using Taxonomies- Microsoft Knowledge Network Group

How do You Use Taxonomies? • Classes of Taxonomies • Content focused/user focused • Global and local ------- • Content creation- tagging • Site navigation- categories • Information retrieval- search • Personalization- delivery Using Taxonomies- Microsoft Knowledge Network Group
Content Creation • Tagging of documents, URLs, other items is critical for improved retrieval • Two examples: • MSWeb Best Bets database- catalog of URLs used in search and categories • News publishing tool- used for tagging external and internal news for portal display Using Taxonomies- Microsoft Knowledge Network Group
Site Navigation • Much of a portal’s navigation centers around organization of information through categories • Categories can be considered a site-specific or local vocabulary, used to tag URLs • MSWeb uses taxonomy management tools for this purpose Using Taxonomies- Microsoft Knowledge Network Group

Future directions Additional groups inside the company leveraging taxonomies and processes for internal AND external use. 2nd generation taxonomy management tool being built -translating terms into multiple languages -sharp focus on relationships between terms allowing more creative query expansion both automatic and interactive KNG responsible for managing global taxonomies, various groups responsible for their own local taxonomies with everyone using the same tool.

Key Success Factors • Define in terms of business value • authority, relevance, timeliness, impact • Include metrics to prove success • Balance between control and collaboration • Meet key stakeholder criteria on costs to build, costs to maintain • Take usability/user behavior seriously • Manage expectations all round Using Taxonomies- Microsoft Knowledge Network Group
Challenges • Finding common ground across multiple taxonomies or schemas with similar terms and different meanings • Overkill…building relationships where they aren’t practical given severe human resource constraints • Ensuring the ongoing integrity of the taxonomy • Acceptance by authors of tagging tools • Application across object types, storage devices, languages, context • Integration with legacy systems and external content Using Taxonomies- Microsoft Knowledge Network Group
Conflicts in Using Taxonomies • Flexibility versus stability • Costs versus resource commitments • Focus versus breadth of scope • Localization versus globalization • Speed versus thoroughness Using Taxonomies- Microsoft Knowledge Network Group
Personalization • The last step in linking content to people • Requires well tagged content, and the ability to capture a user profile • Current directions for MSWeb are to take advantage of Active Directory profiles, based on values pulled from common taxonomy • Still in beginning stages Using Taxonomies- Microsoft Knowledge Network Group
