Table 6 The evidence/test data collected as 20% of the empirical observations. Columns with predicate names having a preceding ‘?’ contain simulated results, which are the probabilities these predicates are true given the evidence data

  1. (a) M1 is short for messhall, the primary muster station, and M2 is short for the alternate muster station, the lifeboat station
  2. (b) True and false are the empirically observed states for the predicates in each column
  3. (c) A predicate starting with a ‘?’ is the one that has been queried in the ELDS module. The remaining predicates are used as evidence/test data in the query process. ELDS module that comprises MLN is queried by employing the MC-SAT inference algorithm
  4. (d) The results of querying for R, HITR, and HES are reported as the probability that the predicates are true given the evidence data. These probabilities are reported as values in parenthesis under the respective columns. A probability value with a subscript M1 stands for the result related with the primary muster station, whereas the one having a subscript M2 refers to the probability that the predicate is true involving the alternate muster station
  5. (e) H1 refers to FIRE emergency, H2 refers to EVACUATE emergency. The probability that a FIRE emergency is occurred is referred to by nH1, and the probability that an EVACUATE emergency has occurred is referred to by nH2, where 0 ≤ n ≤ 1
  6. aThe participant kept impression of FIRE during some time in the beginning of the interval t1
  7. bObserved SMK_VENT during t0
  8. cObserved SMK_VENT during t0
  9. dSMK_MSHA, SMK_STAI, SMK_VENT all observed during t1
