Interactions recorded by online platforms: Wikipedia talk pages and adminship votes, question-and-answer sites, a forum, trust ratings between Bitcoin traders, actions in a course, and GitHub activity. They are large (up to millions of events), with heavy-tailed activity and strong concentration on a few actors, and several are bipartite (users acting on items).

The data catalogue lists every dataset with its licence. Figures and numbers on this page are aggregates computed from the files as published; each section links the source and the code that reads it.

SNAP: Wikipedia talk-page messages: network of the most active actors

Who interacts with whom. The 60 actors of the busiest pairs, out of 1,094,018; events between two of them are 0.6% of all events. Each actor’s three strongest ties are drawn (115 of 255 pairs that ever interacted): wider, darker lines carry more events, larger dots are more active actors, and colours are groups found by modularity (Louvain).

SNAP: Wikipedia talk-page messages: activity of the most active actors over time

When. Each row is one of the 30 most active actors of the network, coloured by its group there; a cell is darker the more events (with anyone) the actor took part in during that stretch of time. The grey bars on top count all 6,100,538 events.

SNAP: Wikipedia talk-page messages: close-up of the busiest stretch, event by event

Event by event. The busiest stretch of the record, Sun 07 May 2006 05:49 to Mon 08 May 2006 00:02, event by event: each vertical line is one event between two of the actors above, from the sender (dot) to the receiver (ring).

SNAP: Wikipedia talk-page messages: counting processes of the busiest pairs

Pairs as counting processes. The counting process N(t) of the 6 busiest pairs: the number of events of the pair up to time t. Together they make 0.1% of all events. Steep stretches are bursts and flat ones silences. 2 of these pairs are the reverse of another, so replies run alongside the messages they answer.

Statistical profile.

SNAP: Wikipedia talk-page messages: activity over time, inter-event times, partners per actor, daily cycle or actor activity

6,100,538 directed events among 1,094,018 actors over 2,277.3 days (3,130,742 distinct ordered pairs). 48.7% of events repeat an earlier ordered pair; if every event chose a pair at random the share would be 0.0%. 29.4% of events answer an earlier event in the opposite direction. The burstiness coefficient of the gaps between successive events of the same pair is 0.58 (0 for a Poisson process, positive when events cluster in bursts); the most active tenth of the actors take part in 85.5% of events (Gini 0.87).

A conditional logit on the first 4,000 events (one sampled control per event) gives:

Each actor’s three strongest ties are drawn (31 of 31 pairs that ever interacted): wider, darker lines carry more events, larger dots are more active actors, and colours are groups found by modularity (Louvain).

GH Archive: one hour of public GitHub events: activity of the most active actors over time

When. Each row is one of the 30 most active actors of the network, coloured by its group there; a cell is darker the more events (with anyone) the actor took part in during that stretch of time. The grey bars on top count all 11,351 events.

GH Archive: one hour of public GitHub events: close-up of the busiest stretch, event by event

Event by event. The busiest stretch of the record, Thu 01 January 2015 15:35 to Thu 01 January 2015 15:41, event by event: each vertical line is one event between two of the actors above, from the sender (dot) to the receiver (ring).

GH Archive: one hour of public GitHub events: counting processes of the busiest pairs

Pairs as counting processes. The counting process N(t) of the 6 busiest pairs: the number of events of the pair up to time t. Together they make 2.1% of all events. Steep stretches are bursts and flat ones silences.

Statistical profile.

GH Archive: one hour of public GitHub events: activity over time, inter-event times, partners per actor, daily cycle or actor activity

11,351 directed events among 11,431 actors over 0.0 days (6,676 distinct ordered pairs). 41.2% of events repeat an earlier ordered pair; if every event chose a pair at random the share would be 0.0%. 0.0% of events answer an earlier event in the opposite direction. The burstiness coefficient of the gaps between successive events of the same pair is 0.19 (0 for a Poisson process, positive when events cluster in bursts); the most active tenth of the actors take part in 36.8% of events (Gini 0.40). 72.4% of events share their time stamp with an earlier one. one hour of public GitHub events, user -> repository (bipartite)

A conditional logit on the first 4,000 events (one sampled control per event) gives:

term estimate s.e.
log(1 + sender’s past events) 0.81 0.05
log(1 + receiver’s past events received) 0.09 0.06
log(1 + past events receiver -> sender) -20.49 1751.03

These coefficients reflect how the data are built, not behaviour: users act on repositories, so reciprocity is impossible.
