Knowledge Synthesis

The last mile of enterprise search. Takes raw results from multiple sources and produces a coherent, trustworthy answer.

The Goal

Transform this:

~~chat result: "Sarah said in #eng: 'let's go with REST, GraphQL is overkill for our use case'"
~~email result: "Subject: API Decision — Sarah's email confirming REST approach with rationale"
~~cloud storage result: "API Design Doc v3 — updated section 2 to reflect REST decision"
~~project tracker result: "Task: Finalize API approach — marked complete by Sarah"

Into this:

The team decided to go with REST over GraphQL for the API redesign. Sarah made the
call, noting that GraphQL was overkill for the current use case. This was discussed
in #engineering on Tuesday, confirmed via email Wednesday, and the design doc has
been updated to reflect the decision. The related ~~project tracker task is marked complete.

Sources:
- ~~chat: #engineering thread (Jan 14)
- ~~email: "API Decision" from Sarah (Jan 15)
- ~~cloud storage: "API Design Doc v3" (updated Jan 15)
- ~~project tracker: "Finalize API approach" (completed Jan 15)

Deduplication

Cross-Source Deduplication

The same information often appears in multiple places. Identify and merge duplicates:

Signals that results are about the same thing:

• Same or very similar text content
• Same author/sender
• Timestamps within a short window (same day or adjacent days)
• References to the same entity (project name, document, decision)
• One source references another ("as discussed in ~~chat", "per the email", "see the doc")

How to merge:

• Combine into a single narrative item
• Cite all sources where it appeared
• Use the most complete version as the primary text
• Add unique details from each source

Deduplication Priority

When the same information exists in multiple sources, prefer:

1. The most complete version (fullest context)
2. The most authoritative source (official doc > chat)
3. The most recent version (latest update wins for evolving info)
