IBM Watson Assistant: Entity overlapping issue in conversation

Question

I am creating a chatbot for students. I am facing a problem in one of my use cases. Students need to get the subjects in a particular year (Bot give the subjects only semester wise). But the problem is I have two entity @year and @semester.

My entity values for @year and @semester is given below. Also I gave some
synonyms for that. @year values are : 1,2,3 @semester values are :1,2

When the user mention as first year the values of @year:1 and @semester is also set as 1, but here actually need to take the input from the user for semester.I already done for ask the semester based on @semester in a slot, but the value set int @semester is not invoking that.

How can I solve this conflict?

My expected conversation is below

Student -Get me the list of subjects in first year.
Bot - Tell me the course name? `enter code here
student - A
Bot - Tell me the semester?
Student - give semester number
Bot - The subjects in first year first semester of A are "Listing Subjects"

But the output is like this

Student - Get me the list of subjects in first year.
Bot - Tell me the course name?
student - A
Bot - The subjects in first year first semester of A are Listing Subjects

Answer 1

I would recommend to check these tips for working with slots , including those on avoiding slot filling confusion .

You would need to add conditions or clarifications when capturing the data. Another option is to break up the conversation in two dialog steps. First, get the year and course name, next, in a separate dialog node, capture the semester and look up the actual information to respond.
