| Summary: | A conversational recommender system has been developed that is able to mimic conversations
like buyers and professional sales support in product search. This system uses ontology as its
knowledge base. This recommendation system utilizes the concept of navigation by asking and
navigation by proposing in generating interactions. However, the system turned out to only use
the mandatory input on product selection. Mandatory input is not used in the product sorting
process. The system only calculates optional input / utility values to sort the product, this results
in the system being unable to sort products in several conditions.
Fuzzy multi-criteria decision making is one of the solutions that can be used to overcome this
problem. All user’s input can be used to build a matrix of relative importance criteria that can be
computed with smartphone specifications to produce values that can replace utility values. From
the test results it was found that this concept succeeded in optimizing all user inputs in providing
recommendations. The order of recommendations produced is also better than the previous
recommendation system. |
