Method and system for probabilistic querying of a vector graph database

A method performed by one or more computers for querying a database, comprising,

• providing a vector graph document database having a Hyper Space Modelling Language (HSML) structure and capable of computation over stored entities using datalinks, wherein said entities include source and destination entities,
• encoding the prior probability of entities in the vector graph document database,
• receiving a user query,
• inferring the posterior probability of the entities based on the user query,
• updating parameters of the vector graph document database, wherein the parameters encode the probability of the relation between source and destination entities, and
• returning the set of entities related to the user query.
