Multi-source summarization combines information from several documents about the same subject. A strong process identifies shared facts, separates source-specific claims, notices contradictions, and writes a concise synthesis that does not imply more certainty than the evidence supports.
The summary should remain traceable to its sources. Systems need rules for credibility, freshness, duplicate reporting, quotation, and unresolved disagreement so repeated weak claims do not appear stronger merely because many pages copy them.

Multi-source summarization reads several accounts and produces one shorter explanation. It should show what the sources agree on, keep important differences, and provide links so readers can inspect the evidence.
For example, three reports may agree that a product launched but give different user numbers. A careful summary can state the confirmed launch and clearly attribute each disputed number instead of blending them into one unsupported claim.
