Table 8.

In this table, we present a SPARQL implementation of a sample 5W1H query

Query: What is the gender of an infected person?
Sample SPARQL implementation:
@prefix ndssl:<http://ndssl.bi.vt.edu/>
@prefix vocab:<http://ndssl.bi.vt.edu/vocab/>
SELECT ?infected_person_gender
WHERE {
ndssl:person#1 vocab:has_sex ?infected_person_gender
}

Here, we are showing a WHAT query. In this query, we assume the infected person ID is given. The vocabulary “has sex” fits of the WHAT type property vocabulary (*sex)
