DBpedia Spotlight performs named entity extraction, including entity detection and Name ... [More] Resolution (a.k.a. disambiguation). It can also be used for building your solution for Named Entity Recognition, amongst other information extraction tasks. Text annotation has the potential of enhancing a wide range of applications, including search, faceted browsing and navigation.

LDIF translates heterogeneous Linked Data from the Web into a clean, local target representation while keeping track of data provenance.

The objective of Cuebee is being completely immersed in SPARQL (but shielding the user from the underlying implementation choices).
