A computer-implemented method includes determining first passages (FP) that provide evidence for one or more first relations (OOMFR) between first entities in a knowledge graph. The method includes generating an evidence index (EI) that associates the FP with the OOMFR and the first entities, receiving a query subsequent to generating the EI, and identifying, using the EI, the FP responsive to receiving the query. The method includes determining presentation aspects of the FP based on similarity information determined for the FP, and determining that second passages of the FP are substantially similar to at least one other passage of the FP. The method includes pruning the FP to generate a pruned set of passages (PSOP) that includes one or more third passages of the second passages and that does not include any other passages of the second passages. The method includes outputting the PSOP according to the presentation aspects.
