Time Trigger Logic implementation

Old Logic

private static void checkIsTimeTriggered( TreeGraphNode node, Collection<TypedDependency> dependencies, Action action) { logger.info("Check for time trigger."); List<TypedDependency> _toCheck = SearchUtils.findDependency(ListUtils.getList("tmod"), dependencies); for (TypedDependency td : _toCheck) { if (td.gov().equals(node)) { action.setTriggerType(TriggerType.TRIGGER_TYPE_TIME); } } }

• Method CheckIsTimeTriggered checks for dependencies

• Dependencies are set in Method CreateSentence via StanfordParser

• In StanfordParser (accessed via Microservice) all dependencies are defined

• For time trigger dependency tmod needs to be found

• With example sentence "Last night I swam in the pool" tmod is found

• with example sentence "create a file on tuesday" tmod not found

• --> tmod checking is not enough to identify time triggers correctly

Helpfull insights

• time trigger information (e.g. on tuesday) is stored in specifier-variable of the action object
• Class WordNetFunctionallity has method isTimePeriod
• ! method isTimePeriod doesn't recognize "am" or "pm" as periods

Idea

• Not checking dependencies anymore
• Checking the string in specifier if it is a time trigger
• Additional check for time information (am / pm)

Updated Logic

private static void checkIsTimeTriggered( TreeGraphNode node, Collection<TypedDependency> dependencies, Action action) { logger.info("Check for time trigger."); Boolean timeRelated = false; String specifier = action.getSpecifiers().toString(); String[] words = specifier.split(" "); String word; for (int i = 0; i < words.length; i++) { word = words[i]; if (WordNetWrapper.isTimePeriod(word)) { timeRelated = true; break; } if ((word.contains("pm")) || (word.contains("am"))){ timeRelated = true; break; } } if (timeRelated) { action.setTriggerType(TriggerType.TRIGGER_TYPE_TIME); } }

Further Ideas

• Looking for more methods in WordNetWrapper such as IsTimePeriod to check even more eventual time information
• Combining dependency check tmod with new logic to cover all eventualities
