Enron Email Network

Description

An Enron email dataset has been made public by the U.S. Department of Justice.

Usage

enron

Format

A directed igraph graph object.

Graph attributes:

  • ‘LDC_names’ The names of the 32 LDC catagories the emails are classfied into by Michael W. Berry (http://www.cis.jhu.edu/~parky/Enron/Anno_Topic_exp_LDC.pdf)

  • ‘LDC_desc’ Longer descriptions of the 32 LDC categories.

  • ‘Citation’ Additionally, see also the references below.

  • ‘name’

Vertex attributes:

  • ‘Email’ Email address.

  • ‘Name’ Real name.

  • ‘Note’ E.g. position at Enron.

Edge attributes:

  • ‘Time’ When the email was sent. Note that some time labels are from 1979, these are certainly wrong and you might want to remove them before analyses that include time.

  • ‘Reciptype’ Recipient type, ‘to’, ‘cc’ or ‘bcc’.

  • ‘Topic’ Assigned based on 3-means clustering of randomly selected 3,120 out of all 125,409 messages, then NN classification for the whole corpus. Note that topic 0 means an outlier, e.g., too few words or all meaningless numbers in the message body.

  • ‘LDC_topic’ Assigned based on Michael W. Berry's 2001 “Annotated (by Topic) Enron Email Data Set.” (http://www.cis.jhu.edu/~parky/Enron/Anno_Topic_exp_LDC.pdf) There are 32 topics. Topic "0" means an outlier, e.g., too few words or all meaningless numbers in the message body, etc. Topic "-1" means there is no matching topic.

Zachary's karate club network

Description

Social network between members of a university karate club, led by president John A. and karate instructor Mr. Hi (pseudonyms).

The edge weights are the number of common activities the club members took part of. These activities were:

  1. Association in and between academic classes at the university.

  2. Membership in Mr. Hi's private karate studio on the east side of the city where Mr. Hi taught nights as a part-time instructor.

  3. Membership in Mr. Hi's private karate studio on the east side of the city, where many of his supporters worked out on weekends.

  4. Student teaching at the east-side karate studio referred to in (2). This is different from (2) in that student teachers interacted with each other, but were prohibited from interacting with their students.

  5. Interaction at the university rathskeller, located in the same basement as the karate club's workout area.

  6. Interaction at a student-oriented bar located across the street from the university campus.

  7. Attendance at open karate tournaments held through the area at private karate studios.

  8. Attendance at intercollegiate karate tournaments held at local universities. Since both open and intercollegiate tournaments were held on Saturdays, attendance at both was impossible.

Zachary studied conflict and fission in this network, as the karate club was split into two separate clubs, after long disputes between two factions of the club, one led by John A., the other by Mr. Hi.

The ‘Faction’ vertex attribute gives the faction memberships of the actors. After the split of the club, club members chose their new clubs based on their factions, except actor no. 9, who was in John A.'s faction but chose Mr. Hi's club.

Usage

karate

Format

An undirected igraph graph object. Vertex no. 1 is Mr. Hi, vertex no. 34 corresponds to John A.

Graph attributes: ‘name’, ‘Citation’, ‘Author’.

Vertex attributes: ‘name’, ‘Faction’, ‘color’ is the same as ‘Faction’, ‘label’ are short labels for plotting.

Edge attribute: ‘weight’.

Bridges of Koenigsberg from Euler's times

Description

The Seven Bridges of Koenigsberg is a notable historical problem in mathematics. Its negative resolution by Leonhard Euler in 1735 laid the foundations of graph theory and presaged the idea of topology.

The city of Koenigsberg in Prussia (now Kaliningrad, Russia) was set on both sides of the Pregel River, and included two large islands which were connected to each other and the mainland by seven bridges

The problem was to find a walk through the city that would cross each bridge once and only once. The islands could not be reached by any route other than the bridges, and every bridge must have been crossed completely every time (one could not walk half way onto the bridge and then turn around and later cross the other half from the other side).

Euler proved that the problem has no solution.

Usage

Koenigsberg

Format

An undirected igraph graph object with vertex attributes ‘name’ and ‘Euler_letter’, the latter is the notation from Eulers original paper; and edge attributes ‘name’ (the name of the bridge) and ‘Euler_letter’, again, Euler's notation from his paper.

This dataset is in the public domain.

Hospital encounter network data

Description

Records of contacts among patients and various types of health care workers in the geriatric unit of a hospital in Lyon, France, in 2010, from 1pm on Monday, December 6 to 2pm on Friday, December 10. Each of the 75 people in this study consented to wear RFID sensors on small identification badges during this period, which made it possible to record when any two of them were in face-to-face contact with each other (i.e., within 1-1.5 m of each other) during a 20-second interval of time.

Usage

rfid

Format

An igraph graph with graph attributes ‘name’ and ‘Citation’, vertex attribute ‘Status’ and edge attribute ‘Time’.

‘Status’ is the status of the person. Status codes: administrative staff (ADM), medical doctor (MED), paramedical staff, such as nurses or nurses' aides (NUR), and patients (PAT).

‘Time’ is the time of the encounter, it is the second when the 20 second encounter terminated.
