Abstract: Systems, methods, and non-transitory computer readable media are configured to generate multiple channel embeddings for a page of a social networking system. The multiple channel embeddings can be mapped to a shared embedding space. A page embedding for the page of the social networking system can then be generated.

Abstract: Systems, methods, and non-transitory computer-readable media can receive a user query comprising one or more search terms. One or more synonyms are identified for the user query based on a dynamic thesaurus generated using automated synonym extraction. An expanded query is generated based on the user query and the one or more synonyms. One or more search results are identified based on the expanded query.

Abstract: Systems, methods, and non-transitory computer readable media can obtain a plurality of page engagement graphs, each of the plurality of page engagement graphs associated with a page engagement type of a plurality of page engagement types. Respective weights associated with the plurality of page engagement types can be determined. An aggregated page engagement graph can be generated based on the plurality of page engagement graphs and the respective weights. Pages in the aggregated page engagement graph can be ranked.

Abstract: Systems, methods, and non-transitory computer-readable media can compute a query embedding in a first multi-dimensional space based on a query embedding model. The query embedding is associated with a user query. A plurality of page embeddings are computed in a second multi-dimensional space based on a page embedding model. A query joint embedding and a plurality of page joint embeddings are computed in a third multi-dimensional space based on the query embedding, the plurality of page embeddings, and a joint embedding model. One or more page results are identified for the user query based on the query joint embedding and the plurality of page joint embeddings.
