Table 4: Bot responses after self-initiated repair
Table 4 shows that, based on this small data set, some self-repair
strategies have a higher success ratio than others. The strategy with
the highest overall success rate – though not one that was frequently
used – was to simply restate the purpose, leading to a relevant
response in every single case. Accommodation, late accommodation and
changing choices also had a more than 50% success rate. Rephrasing –
one of the numerically most frequently used strategies – and changing
the topic were successful in approximately half of all instances,
whereas simply repeating a previously used turn or asking a question
were least likely to be successful.
Generally, users who are able to work through misunderstanding quickly
(within one or two user turns after the trouble source) – deploy those
strategies which have got a higher success ratio:
