Abstract: Abstract Texts are created for humans, who are trained to read and understand them. Texts are poorly suited for machine processing; still, humans need computer help when it is necessary to gain an overall understanding of characteristics and contents of large volumes of text or to find specific information in these volumes. Computer support in text analysis involves derivation of various kinds of structured data, such as numeric attributes and lists of significant items with associated numeric measures or weighted binary relationships between them. Computers themselves cannot give any meaning to the data they derive; therefore, the data need to be presented to humans in ways enabling semantic interpretations. While there exist a few text-specific visualisation techniques, such as Word Cloud and Word Tree, which explicitly represent words, it is often beneficial to use also general approaches suitable for multidimensional data. Collections of texts having spatial and/or temporal references are transformed to data that can be visualised and analysed using general methods devised for spatial, temporal, and spatio-temporal data.We show multiple examples of possible tasks in text data analysis and approaches to accomplishing them.
