## 5.12. Boosting recommendation results

Figure 5.9. Graph

This query finds the recommended friends for the origin that are working at the same place as the origin, or know a person that the origin knows, also, the origin should not already know the target. This recommendation is weighted for the weight of the relationship `r2`, and boosted with a factor of 2, if there is an `activity`-property on that relationship

Query.

    MATCH (origin)-[r1:KNOWS|WORKS_AT]-(c)-[r2:KNOWS|WORKS_AT]-(candidate)
    WHERE origin.name = "Clark Kent" AND type(r1)=type(r2) AND NOT (origin)-[:KNOWS]-(candidate)
    RETURN origin.name AS origin, candidate.name AS candidate, SUM(ROUND(r2.weight
      +(COALESCE(r2.activity,
      0)* 2))) AS boost
    ORDER BY boost DESC LIMIT 10

This returns the recommended friends for the origin nodes and their recommendation score.

Result

origin | candidate | boost
--- | --- | ---
2 rows
`"Clark Kent"` | `"Perry White"` | `22`
`"Clark Kent"` | `"Anderson Cooper"` | `4`
