3.3.3.4 Component interfaces<br />
IContextSource<br />
Containing the following methods:<br />
public String query(String contextQueryExpression);<br />
public String subscribe(String contextSubscriptionCharacterisation, String<br />
contextSubscriptionReference);<br />
public boolean unsubscribe(String contextSubscriptionID);<br />
IDialogueManager<br />
Containing the following method:<br />
IDialogueManager::publish(Data)<br />
Creates a new entry on the blackboard. This entry contains a user input or a system output.<br />
Note that no knowledge source can actually delete an existing entry on the blackboard. At<br />
most, they can mark any entry as “having been processed”, but the actual deletion can only be<br />
realized by the blackboard controller.<br />
Every item that is published onto the blackboard shall conform to the following structure, which<br />
is undefined yet, but which shall minimally contain the following fields:<br />
• ID: unique identifier (given by the blackboard controller)<br />
• Time: time of publication<br />
• Type: speech input, gesture input, graphical output, …<br />
• Semantic content: describes the semantic content of the input or output.<br />
• Ambiguous [Boolean]: when the input is ambiguous (e.g. the user command “delete<br />
this”), it shall be noted here. The Multi-modal Fusion Module can then try to resolve<br />
such ambiguities by combining several.<br />
• ProcessedBy: the list of clients id that have processed this item so far.<br />
• Priority: Several knowledge sources may change the priority of treatment of this item:<br />
for instance, when concurrent outputs shall be delivered to the same user.<br />
It may be possible to further provide a “subscription helper” that simplifies the subscription<br />
mechanism for external applications: the idea would be to implement a simple subscription()<br />
function (with attribute/value matching instead of a full SPARQL query) that activates the<br />
complete subscription() method and returns another helper, which can be used by the<br />
application to simplify accordingly the SPARQL answer.<br />
