I am puzzled by the following sentence found in Section 5.2.2:
An example of such a path extracted from Figure 5.2 might be, for example, San Pedro–bus➛Calama–flight➛Iquique–flight➛Santiago, where the paper experiments with 500 paths of length 8 per entity.
The part until "Santiago" is clear, but the remainder does not seem to make any sense wrt the beginning of the sentence.
