+description = """Results of the games of four national football (soccer) leagues, one network per season, compiled by hand from Wikipedia by Fanuel and Suykens, as distributed by KONECT:
+
+- `be1_2016`: Belgian Pro League, season 2016/2017;
+- `de1_2016`: German Bundesliga, season 2016/2017;
+- `fr1_2016`: French Ligue 1, season 2016/2017;
+- `uk1_2013`: English Premier League, season 2013/2014.
+
+Each node is a team, and a directed edge from team A to team B is a game that A played at home against B. The edges are signed by the goal difference (positive if the home team won, negative if it lost, zero for a draw); the scores of the games are not included. Only the games of the regular seasons are included (in `be1_2016`, 239 of the 240 games of the regular season; one is missing). The data identify the teams only by indices (their names are not included).
+
+The networks have the following properties:
+
+- Edge `goal_difference`: the goals of the home team minus the goals of the away team."""
