SYSTEM FOR RAPID INGESTION, SEMANTIC MODELING AND SEMANTIC QUERYING OVER COMPUTER CLUSTERS

摘要

A system comprising a cluster of computers for ingesting and analyzing data sets that together comprise of at least one gigabyte is disclosed. The system is configured for reading an input data set, generating a source data model based on the input data set, generating a vocabulary annotation and a profile of said source data model, executing semantic processing on models including said source data model, so as to produce a target data model, said semantic processing including: 1) executing semantic integration of said data models and constructing said target data model, and 2) defining a transformation from the data models to said target data model, executing said transformation so as to populate said target data model with a transformed data set, and executing semantic querying on said target data model, using an ontology defined by said target model and using parallelized ontology reasoning.
