Therefore, our approach comprises two successive stages: • A disambiguation stage (Section 5) where all KB i ∈ K are linked to S, either by inter-resource mapping (Figure 1(a)) or disambiguation ( Figure 1(b)), and all E i are merged into a unified set of entities E * .
of this process we obtain a set K S comprising all the KBs in K redefined using the common sense inventory S; • An alignment stage (Section 6, Figure 1(c)) where, for each pair of KBs KB S i , KB S j ∈ K S , we compare any relation pair r i , r j , r i ∈ R S i and r j ∈ R S j , in order to identify cross-resource alignments and merge relations sharing equivalent semantics into relation clusters (relation synsets).
