Why temporal relations

Why Temporal Relations?


Experimentation

Experimentation

  • Step 1: Eliminate Unnecessary datasets and identify the most frequent Itemset using Apriori Algorithm.

  • Step 2: Use Weight based Relation analysis to identify best relation to remove ambiguity.


Step 1 the apriori algorithm example

Step 2 relation formation

Table 3: Sample of Frequent Relation Pairs.

Step 2: Relation Formation

  • Use the above define temporal relations with the weight based rule given below to identify the best temporal relations.


Future directions

Future Directions

  • Prediction of activity.

  • Anomaly detection mechanism.

  • Visualization of temporal intervals for monitoring daily activities and lifestyle.
