A technique for providing search results may include determining a first entity type, a second entity type, and a relationship type based on a compositional query. The technique may also include identifying nodes of a knowledge graph corresponding to entity references of the first entity type and entity references of the second entity type. The technique may also include determining from the knowledge graph an attribute value corresponding to the relationship type for each entity reference of the first entity type and for each entity reference of the second entity type. The technique may also include comparing the attribute value of each entity reference of the first entity type with the attribute value of each entity reference of the second entity type. The technique may also include determining one or more resultant entity references from the entity references of the first entity type based on the comparing.

Providing search results based on a compositional query

Implementations provide an enhanced search result to improve the user search experience. For example, the result may include insightful information relevant to the search query that was not specifically requested but that the user may find interesting, such as relationships shared between the two entities related to the query, a relationship between the two entities that does not commonly occur with another relationship shared by the entities, or strong secondary connections for an entity related to the query. In some implementations, insightful connections may also be unique facts for a particular entity. Unique facts may represent a superlative attribute of an entity such as, for example, the tallest actor, the oldest president, the most expensive stock, etc. Such shared relationships, rare relationships, and/or unique facts may be provided as part of the search results presented to the query requestor and may provide insight to the requestor about the entity.

Reducing near-duplicate entries in online shopping system search results. For each pair of entries in a set of entries, each entry characterizing a product in a data store of an online shopping system and each entry characterized by a set of attributes, determining a distance between the entries in the pair based on the attributes. Determining entry clusters from a graph formed with each determined distance as an edge between nodes representing the entries used to determine the distance, each entry cluster identified by cluster identifier. Returning an ordered list of results responsive to the query from the data store of an online shopping system, filtered as a function of at least one of the distance and the cluster identifier.
