Here are all the past exams in INFO216:


About the Spring 2022 exam:

  • There is a problem with question 22: The answer states that hasSibling (excluding half-siblings) is Symmetric and Transitive, and also Irreflexive. But, if there is at least one pair of siblings, symmetry+transitivity implies reflexivity, so it cannot in practice be Irreflexive too. When there are errors like this in the questions, we always grade to your advantage as students: so that both the anticipated and correct answers are given full score.
  • On Task 3, BIBO is no longer in the curriculum.

About the Spring 2021 exam:

  • On Task 2, these vocabularies are no longer in the curriculum: BIBO, BIO, MO, VS, VANN
  • On Task 3, this open KG is no longer in the curriculum: EventKG
  • The questions about OWL properties were open to interpretations so there may be more ok answers than indicated.
  • Additional information given during/after the exam:
    • Unfortunately, there is an error in the first question in part 3 of the INFO216 exam: "Which open knowledge graph (or knowledge base) is best matched?"
      • "Contains information about more than 90 billion things." This should have said "millions", not "billions", so we will ignore this question during the correction ... Sorry about that!
    • On the last question in part 5, we will of course accept both answers with "city population" and with "city count":
      • "Continue with the same triple store. Extend the previous SPARQL query so that it lists the city population in each region in Norway in descending order."
