| 4 | PTSD patients often have fragmented memories of their trauma and are very reluctant to recall them, requiring detailed questions to stimulate memory retrieval. Previously, a system was developed that showed the effectivity of an ontology- based dialog system to help humans to recall their traumatic experiences [Tielman(2018)] These ontologies have been tested and shown effective with real subjects. Support for different languages is available, and new languages can be added easily. The strategies used to traverse the ontologies can be adapted as required. |
