Entity Resolution
The problem of deciding whether records, names, or observations from different sources refer to the same real-world entity.
The same person, organization, or technical concept can appear across sources under different spellings, abbreviations, and identifiers. Entity resolution attempts to connect those records using context, stable identifiers, and relationships rather than surface-string similarity alone.
False merges and missed matches usually have different costs, so the decision threshold depends on the application. In search and knowledge graphs, correct resolution also affects retrieval by concentrating otherwise fragmented signals on one entity. The multimodal context is related to natural-language processing and multimedia.
