Latest Patents

Rajesh Patel holds a patent for "Row level security in natural language question answering." This patent describes a natural language question (NLQ) query service within a service provider network that provides row level security (RLS) for autocomplete during entry of NLQs and fuzzy matching in NLQ answering. The rules take the form of per-user predicates, such as "Tim can only see rows with region=US." In configurations, a complex extraction and preprocessing pipeline is utilized to extract distinct combinations of values against the RLS predicate 'rule keys.' These distinct values are indexed along with grouped rule keys to enable pushing down predicates at auto-complete time. This innovation allows for part of the RLS rule handling to occur during the ingestion time of a dataset, rather than at query time, thereby meeting latency goals. Additionally, a single logical document of unique cell values can be split into multiple documents with a subset of rule keys to handle scalability limits.
