Concept Searching has announced conceptClassifier for SharePoint 2013. It explains the product is a key component in expediting the development, testing and validating of multiple term sets, and the ongoing management, to address the flux of information as organizational objectives change and information is added. Further, it says, SharePoint 2013 still has no automatic concept extraction capabilities to populate the term sets, nor auto-classification capabilities to align content.
Using conceptClassifier for SharePoint, which is integrated with the Content Search Web Part, the search index can contain multi-word, automatically generated metadata. The search experience will be improved as the index captures the essence or meaning of content to achieve relevant search results without manual intervention.
