With the evolution of data mining systems, acquisition timely insights from unstructured text is an organizational demand which gradually increasing. The existing opinion systems have a variety properties, such as ranking products’ features and feature level visualizations; however, organizations require decision-making based upon customer feedback. Therefore, system proposed in this work that ...

In view of the multi-attribute decision-making problem that the attribute values are grey multi-source heterogeneous data, a decision-making method based on kernel and greyness degree is proposed. The definitions of kernel and greyness degree of an extended grey number in a grey multi-source heterogeneous data sequence are given. On this basis, we construct the kernel vector and greyness degree...

Generalized trapezoidal fuzzy numbers (GTFNs) have been widely applied in uncertain decision-making problems. The similarity between GTFNs plays an important part in solving such problems, while there are some limitations in existing similarity measure methods. Thus, based on the cosine similarity, a novel similarity measure of GTFNs is developed which is combined with the concepts of geometric...

The complex multi-attribute large-group decision-making problems that are based on interval-valued intuitionistic fuzzy information have become a common topic of research in the field of decision-making. Due to the complexity of this kind of problem, alternatives are usually described bymultiple attributes that exhibit a high degree of interdependence or interactivity. In addition, decision mak...
