Bot with QnA in Portuguese Shows Answers that Have no Relation (Doc ID 2462924.1)

Last updated on APRIL 17, 2019

Applies to:

Mobile Cloud Enterprise - Version 17.4.1 and later
Oracle Digital Assistant - Version 18.3.5 and later
Information in this document applies to any platform.

Symptoms

Bot with QnA deployed on Autonomous Mobile Cloud Enterprise 18.2.5.
QnA is only for Portuguese.

QnA seems to have issues when matching the questions/answers causing bot to reply with complete non-sense.
Here, the bot continues to match works like: "campeão" or "campeao" (champion) with words like "campo" (field) or "campanha" (campaign). These words have no relation.
Attempts were also made to use the configuration for QnA with minimumMatch: "100%,100%".

As per document : Creating Intelligent Bots with Oracle Autonomous Mobile Cloud Enterprise - Chapter 15 Reference - System.Qna

If you want to minimize irrelevant matches, then you can increase the levels (say, 60%,50%). Keep in mind doing so might exclude Q&A pairs that have all of the keywords.

But it was noticed that this seems to not affect the bot at all, as it continues to return questions as mentioned before.
