Fuzzy transform; Fuzzy natural logic; F-transform; Time series

In this paper, we discuss application of special soft computing methods, namely the fuzzy natural logic and fuzzy transform, to the problem of mining information from time series. The mined information is formulated in natural language. We discuss the following applications: reduction of size of time series, extraction of its trend-cycle, linguistic characterization of its future course and forecast of future values, finding perceptionally important points, extraction and linguistic evaluation of local trend in a given area, and summarization of characteristics of time series using generalized intermediate quantifiers.
