#Taxonomy Strategies The business of organized informationCompleteness and consistency: Indexer consistency

Studies have consistently shown that levels of consistency vary, and that high levels of consistency are rare for: IndexingChoosing keywordsPrioritizing index termsChoosing search termsAssessing relevanceChoosing hypertext links

#Taxonomy Strategies The business of organized informationHybrid method: Fashion-forward product recommendationsIndexes are derived from multiple attributes and sourcesInitial weighting can be heuristic and adapted based on user behaviorIndex attributes enable analytics and personalization to bootstrap from and leverage Macys merchandising expertiseLikert scales (1-5) are sufficient for manually set index attributesFor automated scoring, use more granular, relative scales.Index AttributeValue TypeSourceBoldness1-5Merchandising NewnessLogarithmicDerived from release dateBrand Fashion1-5Derived from brandLifestyle1-5MarketingProduct Review1-5Fashion Forward Customers

#Taxonomy Strategies The business of organized informationIndexes will be used to provide scoring products so that they can be recommended to customers. Indexes should be multi-dimensional and consist of a combination of 1) ratings by customers and/or merchandisers, 2) product attributes, and 3) analytics. A common rating method is based on goodness meaning best fit for certain criteria. For example, to build a fashion-forward index, goodness would be a relative score of boldness. Scoring is should be done using a Likert scale of 1 to 5. The fashion-forward index should include the following 5 indexes:Boldness. A score of 1 to 5 for each SKU made by MCOM merchandisers, where most bold is 5 and least bold is 1.Newness. A score of 1 to 10 will be automatically assigned where 10 is newest and 1 is oldest. The score should be calculated logarithmically so that newness is weighted very heavily and drops off quickly.Brand Fashion. Merchandisers will score all brands on a scale of 1 to 5, where 5 is most fashion-forward and 1 is least. Lifestyle. Marketers will score all customer lifestyles on a scale of 1-5, where 5 is the most fashion-forward and 1 is the least.Product Review. A score of 1 to 5 will be generated from Bizarre Voice customer ratings.Other potential index dimensions:Past Transactions. Based on past transactions, a relative score will be assigned based on whether customers who bought the product are coded with Lifestyles = fashionista.Inventory. A score is calculated based on threshold amounts of inventory.Additionally, there should be a way for merchandisers and marketers to provide a specific recommendation for a specific SKU (e.g., particular shoes for a particular dress), a category of products as a recommendation (e.g., gloves for coats), or a category with certain attributes as a recommendation (e.g., yellow silk scarf for a blue silk suit)Justification: MCOM wants to reinforce their brand as a merchant who sells fashionable products. Being able to recommend fashion-forward products will distinguish the MCOM user experience, and potentially increase sales by lift and up-selling. The new category and attribute model provides great flexibility to cross merchandise and up-sell.22Questions?Joseph A Busch, Principaljbusch@taxonomystrategies.comtwitter.com/joebusch415-377-7912

#Taxonomy Strategies The business of organized information23#Taxonomy Strategies The business of organized informationEvaluating TaxonomiesTaxonomies are developed in communities and evolve over time. From the outset there is a need to evaluate existing schemes for organizing content and questions about whether to build or buy them. Once built out and implemented, taxonomies require ongoing revisions and periodic evaluation to keep them current and structurally consistent. Taxonomy evaluation includes the following dimensions which will be discussed in this webinar.Editorial evaluation including depth and breadth, comprehensiveness, currency, relationships, polyhierarchy (is it applied appropriately), and naming conventions.Collection analysis - category usage analytics (is distribution of categories appropriate), completeness and consistency, and query log/content usage analysis.Market analysis including industry standards/leaders, user surveys, card sorting, and task based usability.Examples will be provided from public, non-profit and commercial client projects.
