A fast moving and powerful introduction to both the theoretical and practical aspects of building a taxonomy, thesaurus, and ontology. A well-built taxonomy is part of the foundation of the information architecture underlying web sites, corporate Intranets, search/retrieval, and access to relevant content in databases. After defining controlled vocabularies and identifying core standards, you will explore key concepts of taxonomy, thesaurus, indexing, classification, and filtering. Discussion will include the basics of a taxonomy records and fundamental term relationships. Attendees will put concepts into practice through multiple exercises, taxonomy, indexing, and related software tools will be demonstrated.

Taxonomies are found…
• In “indexing”, tagging, categorizing, subject metadata• In search - precision, recall• In content management systems, web sites• In SharePoint to replace term tree, tag uploads• In mashups, repackaging, repurposing data• In social networking sites• In author tagging - peer reviewer selection• In filtering data – e.g., spam filters and RSS feeds• In web crawlers• In text analytics – trend analysis• … and much more

Where Does Implementation Happen?
At the backend When the records / articles are added to
the production system When the search software’s “inverted file”
is created When the HTML for the web page is
created

Recent studies suggest that the increased risk of breast cancer associated with alcohol consumption may be reduced by adequate folate intake. We examined this question among 66,561 postmenopausal women in the American Cancer Society Cancer Prevention Study II Nutrition Cohort.

Vocabulary Control – How?
Use unambiguous terms, clear to the user group
Distinguish between terms that appear similar
Use Scope Notes when necessary Use terms as elements that can be
coordinated in a flexible manner Create compound terms, if necessary

Term Format
KISS – Keep it short and simple• 1-2-3 words• Effect on search• Pre and Post Coordination
Establish a policy • follow Chicago Manual of Style
Grammatical issues • Nouns and noun phrases• Verbs Gerunds • Adjectives - no• Adverbs - no• Initial articles – no

Organize Terms – Roughly
Sort terms into several major categories – logical groups of similar concepts as Top Terms Identify core areas and peripheral topics 10 – 20 to start Consider moving proper names to authority files

Bayesian Methods - Cautions (continued)
A Bayesian network is only as useful as the prior knowledge is reliable.
An optimistic or pessimistic expectation of the quality of these prior beliefs will distort the entire network and invalidate the results.
Must ensure the selection of the statistical distribution induced in modeling the data.
Must have the proper distribution model to describe the data.
That is… you have to constantly train and retrain the data
