For each such triple (a, s, ) ∈ U π , we apply the following disambiguation heuristics: • One sense per page: if another occurrence of a in the same Wikipedia page (independent of the lexical predicate) is linked to a page l, then remove (a, s, ) from U π and add (a, s, l) to D π .
we propagate an existing annotation of a in the same Wikipedia page and apply it to our ambiguous item.
