knownrelationships

Known relationships are connections between two or more entities that are documented, verified, and generally accepted as accurate within a given domain. They contrast with unknown, uncertain, or inferred relationships that have not been directly observed or confirmed. In practice, known relationships are used to build representations of how entities are linked, such as in genealogical trees, corporate registries, social networks, or knowledge graphs.

In genealogy and family history, known relationships include parent-child, spousal, and other kinship ties recorded in official records. In business, law, and governance, known relationships encompass corporate ownership, contractual alliances, fiduciary roles, and regulatory connections that are documented in filings, agreements, and public records. In data science and information systems, edges in knowledge graphs or relational databases often encode known relationships, enabling queries about influence, collaboration, or hierarchy. Researchers distinguish known relationships from potential or inferred connections, which may be suggested by data patterns but lack direct confirmation.

Methods for establishing known relationships rely on primary sources and verification across multiple records or authorities. Challenges include data errors, name changes, incomplete records, and time-sensitive updates that require versioning. Privacy and ethical considerations arise when documenting sensitive ties, such as family medical history or confidential business relations, mandating careful handling and governance.

Known relationships underpin many analytical and operational tasks, from lineage tracing and due diligence to network analysis and recommendation systems. Related concepts include ground truth, knowledge graphs, edges, and relational databases.
