A method for inferring a probability of a first inference. The inference
is related to identification of a cause of an outcome in a healthcare
setting. A fact, related to the query, is related to the healthcare
setting. The fact further relates to a network of interactions associated
with the outcome. Each datum of the database conforms to the dimensions
of the database. Each datum of the plurality of data has associated
metadata and an associated key. The associated metadata includes data
regarding cohorts associated with the corresponding datum, data regarding
hierarchies associated with the corresponding datum, data regarding a
corresponding source of the datum, and data regarding probabilities
associated with integrity, reliability, and importance of each associated
datum. The query establishes a frame of reference for the search. The
database returns a probability of the correctness of the first inference
based on the query and on the data.
