The world is changing at a rapid pace, and taxonomies must adapt or die. Recent news stories about global terrorism can fill dozens of categories, which were not necessary only five years ago.

As time goes by, some categories become redundant, others need to be created, and yet others start to serve a different purpose than originally intended. This is taxonomy lifecycle management: The ability to continuously adapt the tree of topics to the changing news environment.

The Taxonomy Manager: Simple and Powerful Taxonomy Editing

GammaSite's Taxonomy Manager is an application that allows information managers to edit and manage taxonomies throughout their lifecycle:

• A Category Suggesting Tool can suggest how to split a large category into subcategories, or perform initial clustering when there is no taxonomy structure. This dramatically reduces time spent by information experts on analyzing changes required in a taxonomy.

• Adding or deleting categories is as easy as working with folders in Windows File Explorer. Categories can be moved to a different position in the tree using drag-and-drop.

• It is simple to update training documents, in accordance with changes to the subject tree. The Taxonomy Manager allows information experts to quickly add examples by dragging-and-dropping a URL or file into a category. It also displays detailed information on the quality of each training document, making it easy to zone in on problematic documents and remove them.

• Full control of categorization parameters. The Taxonomy Manager allows information experts to fine-tune global categorization thresholds, and set specific threshold for problematic categories.

• Category links. The Taxonomy Manager allows creation of 'contain' or 'see also' links between related categories. This is a standard linking method that maintains taxonomy consistence without sacrificing usability.
