摘要：A recommendation engine may provide recommendations by obtaining acompact graph representation representing a recommendations graph comprising ofnodes and weighted edges. Each node is associated with type metadata indicating that it
represents a recommendable item or a non-recommendable item. Each weighted edge isassociated with edge-weight metadata. The compact graph representation can be storedin primary memory. When servicing a request for an item recommendation, therecommendation engine selects an entry node based at least in part on contextmetadata associated with the request, and traverses only a highly-weighted portion ofthe compact graph representation that is proximate to an entry node to select pathsleading respectively to potential recommendation nodes. Each path is scored based onthe edge-weight metadata of all segments, and at least one recommendation node isselected based at least in part on the path scores.
