35. The system of claim 23 wherein the one or more computing devices are configured to: group the fact triples into a plurality of quarantine groups by adding each fact triple to a plurality of fact buckets, each fact bucket being defined by the corresponding fact characteristic shared by all fact triples added to that fact bucket; and wherein the one or more computing devices are configured to determine the reliability for each quarantine group by: for each fact bucket, determining whether each of a first number of fact triples added to that fact bucket is true or false with respect to the knowledge base; and designating each fact bucket as one of reliable, unreliable, or unknown based on one or both of a first number of fact triples added to that fact bucket determined to be false, or a second number of fact triples added to that fact bucket determined to be true.
38. The system of claim 35 wherein the fact characteristic by which each of a subset of the fact buckets is defined comprises one of the following: fact triples for which at least one of the two corresponding entity objects is the same; fact triples for which the corresponding relationship object is the same; fact triples that originate from the same source; fact triples that originate from the same individual; fact triples having common lexical elements; or fact triples translated from corresponding ones of the simplified assertion statements using a common translation template.
