    • Overview: The Lehigh University Benchmark is developed to facilitate the evaluation of Semantic Web repositories in a standard and systematic way. The benchmark is intended to evaluate the performance of those repositories with respect to extensional queries over a large data set that commits to a single realistic ontology. It consists of a university domain ontology, customizable and repeatable synthetic data, a set of test queries, and several performance metrics.
    • Components:
      • Ontology: The benchmark ontology is named Univ-Bench. It has two versions: OWL Version and DAML Version.
      • Data Generator(UBA): This tool generates syntetic OWL or DAML+OIL data over the Univ-Bench ontology in the unit of a university. These data are repeatable and customizable, by allowing user to specify seed for random number generation, the number of universities, and the starting index of the universities.
      • Test Queries: The benchmark currently provides 14 test queries. Here they are written in a KIF-like language, expressing a query as a conjunction of atoms. Examples of using other languages such as RQL can be found in the download of the test module below.
      • Tester (UBT): The test module. It carries out both data loading test and query test, with configurable test plans.
