Whether automatically extracted or human generated, open-domain factual knowledge is often available in the form of semantic annotations (e.g., composed-by) that take one or more specific instances (e.g., rhap- sody in blue, george gershwin) as their ar- guments. This paper introduces a method for converting flat sets of instance-level annotations into hierarchically organized, concept-level annotations, which capture not only the broad semantics of the desired arguments (e.g., ?People? rather than ?Loca- tions?), but also the correct level of general- ity (e.g., ?Composers? rather than ?People?, or ?Jazz Composers?). The method refrains from encoding features specific to a partic- ular domain or annotation, to ensure imme- diate applicability to new, previously un- seen annotations. Over ...
