Obtaining a complex linguistic data summaries from database based on a new linguistic aggregation operator

Abstract

In real-world database, generally, attribute values of objects are numerical, from real-world practice point of view, numeral is too detail to obtaining good information or decision. Hence, a linguistic data summary of a set of data, which is expressed by a sentence or a small number of sentences in a natural language, would be very desirable and human consistent. In this paper, from the structure and valuation of fuzzy statement point of view, extracting linguistic data summarize is discussed. To extract complex linguistic data summaries, a new aggregation operator for aggregating linguistic terms is proposed, a numerical example of Personnel Database is also provided. © Springer-Verlag Berlin Heidelberg 2005.
