Test yourself, answer these questions
- Read Chapter 6 (Other Info)
- Read OWL and Rules: http://semantic-web-book.org/w/images/5/5e/KI09-OWL-Rules-2.pdf
Try to understand the examples.
Expected progress so far
- Establish a scenario described by use case - done
- Have a verbal expression of queries - done
- Have taken a decision to work with
- Protégé 3.5 with SWRL or SQWRL or
- Protégé 4.3 with DL Query og SPARQL
Working on
- Apply SWRL or SPARQL to your ontologies
- Discussion on short-term (decisions) versus long-term (knowledge-creation). Typical time frames for knowledge-update are 1/hour or 1/day, whereas decisions are taken about 10/min or 1/min (see slide 3-5 in Media:UNIK4710-L10-v14.pdf)
- Discussion on "history" of decisions, to be taken into consideration through "weighted context"
Upcoming
- Interfaces to programmes (APIs) to work with your knowledge base. Typical APIs are OWL, Protege, Jena and SPARQL
- Programming your scenario
- Presentation of your integrated solution

SWRL examples
- Is the person running?
Person(?person) ∧ hasSpeed(?person, ?speed) ∧ swrlb:greaterThanOrEqual(?speed, 10) → hasStatus(?person, running)
- Is Susana walking?
Person(Susana) ∧ hasSpeed(Susana, ?speed) ∧ swrlb:greaterThanOrEqual(?speed, 1) → hasStatus(Susana, walking)
- which songs the person likes
Person(?person) ∧ hasPreference(?person, ?prefer) ∧ Music(?music) ∧ hasStyle(?music, ?prefer) → like(?person, ?music)
- LowRisk state range for the persons who have a passive action and a heart rate between 81 – 120
Person(?p) ∧ LowRiskState(?n) ∧ Passive(?y) ∧ hasAction(?x, ?y) ∧ hasHeartRateOf(?x, ?z)∧ swrlb:greatherThanOrEqual(?z, 81) ∧ swrlb:lessThanOrEqual(?z, 120) → hasHealthCondition(?x, ?n)
