wiki_cs_links — Wikipedia computer science articles, links and words (2008)

Description

Networks of the English Wikipedia articles on computer science, from the dump of October 8, 2008, compiled by J. Tang and colleagues (Tsinghua University) to study the semantics of hyperlinks ("topic distributions over links"), and distributed by AMiner. The data set contains 14,468 articles, starting from "Computer science".

links: hyperlinks between the articles. Nodes are articles, and a directed edge $i \to j$ is a hyperlink from article $i$ (source) to article $j$ (target). Some article pairs are linked several times, kept as parallel edges (25,817 links between 22,432 pairs). Each link has a label giving its annotated category, following the specification of the authors: 0, "drill down" (a link from summary information to detailed information, or to a basic theory used in the source); 1, "similar" (a link between pages with similar content); 2, "other"; the meaning of the label 3, used for 1,138 links, is not documented. Articles without links are isolated nodes.
words: a bipartite network of articles and the words of their abstracts. Nodes are articles and words, and an undirected edge connects an article to a word contained in its abstract (263,634 edges between 13,972 articles and 26,093 words).

The data set also lists the words near the anchor text of each link, which are not included here.

The networks have the following properties:

title: the title of the article (empty for words).
wiki_id (articles): the identifier of the article in the Wikipedia dump (-1 for words).
label (links edges): the link category, as above.
is_article (words): whether the node is an article (otherwise it is a word).
word (words): the word (empty for articles).
