Fuzzy linguistic summaries: Where are we, where can we go?

Along with the increase of the amount of data stored and to be analyzed, different techniques of data analysis have been developed over the years. One of them, the linguistic summary, aims at summing up large volume of data into simple sentences. In this paper, we present an overview of two main streams of research, namely fuzzy logic based systems and natural language generation, covering the methods designed to work with numerical data, time series, or simple labels (enumerations). We focus on the former stream and we give some hints to go further on fuzzy quantifiers.
