Penalty-based aggregation of strings

Whereas the field of aggregation theory has historically studied aggregation on bounded posets (mainly the aggregation of real numbers), different aggregation processes have been analysed in different fields of application. In particular, the aggregation of strings has been a popular topic in many fields featuring computer science and bioinformatics. In this conference paper, we discuss different examples of aggregation of strings and position them within the framework of penalty-based data aggregation
