Extensions to Linguistic Summaries Indicators based on Neutrosophic Theory, Applications in Project Management Decisions

Abstract

The quick development of the markets and companies, especially those that apply information technology, has made
it easy to store a large volume of digital information. Nevertheless, the extraction of potentially useful knowledge is difficult;
also could not be easily understandable by humans. One of the techniques applied to the solution to this problem is the linguistic data summarizations, whose objective is to discover knowledge to extract patterns from databases, from which are generated explicit and concise summaries. Another important element of the linguistic summaries is the indicators (T) for their
evaluation proposed by Zadeh when including linguistic terms evaluation in fuzzy sets. However, these indicators not include
the analysis in indeterminate sets. In this paper, it is discussed the use of linguistic data summarization in project management
environments and new T indicators are proposed including neutrosophic sets with single value neutrosophic numbers. Authors
evaluate T-values proposed by Zadeh and T-values based on neutrosophic theory in the evaluation of linguistic summaries recovered.
