Building, reusing and calibrating network of authored content, in one aspect, may comprise clustering a plurality of problem tickets into one or more clusters. The clusters may be associated to one or more FAQ nodes in a FAQ network. The associated one or more FAQ nodes may be checked to determine whether the nodes are part of a broken branch. If the one or more FAQ nodes leads to a broken branch, a user may be notified to update the branch, e.g., with an answer or resolution to the one or more FAQ nodes.
