[entries] Fix parse bugs and improve the metadata of existing entries c996a0e
From a review of the dataset descriptions against the upstream sources and papers, and from user reports: - parse fixes (wrong edge direction or directedness, shifted or misnamed properties, merged node identities, duplicated or missing edges and nodes, wrong types), e.g. arxiv_citation (the HepTh dates were a copy of the HepPh ones; now from the KDD Cup 2003 data), eu_procurements, foursquare_global, hiv_transmission, genetic_multiplex, gnutella (adds the 05 snapshot), roadnet, macaque_neural, python_dependency - descriptions rewritten from the upstream sources, documenting every property - corrected titles, citations and DOIs, licences (ustream_license typo, the data's own terms), tags and ICON ids - url lists for entries with several sources or dataset pages - SocioPatterns entries moved to the site's new data location, with the daily networks of sp_infectious and sp_primary_school - the Michael Fire entries marked as orphans (served from the mirror) - redundant type forcings removed after the graph-tool coercion fixes

+description = """Friendship network of Pokec, the most popular online social network in Slovakia, which had been operating for more than 10 years and connected more than 1.6 million people when the data were collected by L. Takac and M. Zabovsky (published in 2012). The data are anonymized and cover the whole network. Nodes are users, and a directed edge $(i,j)$ indicates that user $i$ lists user $j$ as a friend; friendships in Pokec are oriented (not necessarily reciprocated). The user IDs of the source data run from 1 to 1,632,803; the node with index $i$ corresponds to the user with ID $i+1$. The data were obtained from the Stanford Network Analysis Project (SNAP).
+
+The source data also include user profiles (in Slovak), with information such as gender, age, region, hobbies, interests and education, but these are not included in this network."""
