Liferay Portal Development – Taxonomies and Folksonomies
Filed under: Parenting

Folksonomies can be added as quickly as users require them and is a great tool for social discovery. They have user-driven approach that helps in organizing content through tags, cooperative classification and interaction via shared metadata. Folksonomies are executed by Portal with the use of tags that are associated to many assets and which may have many tags. This is known as tagging content. Also tag may have many properties and each property is made up of name-value pair. There are many drawbacks found in Folksonomies that stem out from its lacking vocabulary control resulting into erroneous, ambiguous and redundant keywords. Folksonomies can be helpful but cannot replace taxonomy.

Taxonomies and Folksonomies can coexist in SharePoint 2010.Taxonomies are designed to provide the most favorable experience for all stakeholders. They are a hierarchical structure used in scientific classification schemes but are difficult to execute. Taxonomies are executed as vocabularies by the portal and also as category trees for tagging contents and for classifying them. In SharePoint 2010 it allows to control folksonomies bymonitoring user-submitted keywords. This would help one to choose promotion of managed taxonomy or can delete keywords that seem problematic.
