Abstract: In a method of compressing a similarity network, the similarity network has nodes with a plurality of repetitions of characters sequences and a plurality of edges. Each edge connects a pair of the nodes based on a first similarity threshold. The method includes clustering of the nodes according to a second similarity threshold, where the second similarity threshold is higher than the first similarity threshold.

Abstract: A wheelchair transportation system for transporting a wheelchair over at least one obstacle, including a wheelchair transportation unit being operable to transport the wheelchair over the at least one obstacle during at least one transportation operation of the wheelchair.
