title: Collection of datasets (Karate, Football, Dolphin, PolBook, PolBlog, Email, CiteSeer, CORA, PubMed, and DBLP) for a parallel stacked autoencoder-based method driven by semi-supervised learning for community detection in social networks

description: ·       Zachary Karate Club (Karate): This dataset, collected by Wayne Zachary in 1977, represents the social network of members in a university Karate club. Each node represents a club member, and edges denote contact or interaction between members.

·       Bottlenose Dolphin (Dolphin): This dataset represents the social interactions of 62 dolphins in New Zealand's Doubtful Sound. It is an undirected network with two main communities, where the larger group is further subdivided into smaller groups.

·       American Football (Football): The American Football dataset captures games played between 115 Division IA teams during the 2000 Fall season. Each node represents a team, and edges represent games between teams. The teams are grouped into 12 conferences, with more frequent games occurring within each conference.

·       Political Books (Polbooks):  The Polbooks dataset includes 105 nodes representing books about U.S. politics sold on Amazon around the 2004 presidential election. Edges indicate that the same customers frequently bought these books together.

·       Political Blogs (Polblogs): This dataset includes 1490 blogs about US politics, created by Adamic and Glance in 2005.  Each node represents a blog classified as either liberal or conservative. Edges represent links between blogs.

·       Email-Eu (Email): The Email-Eu dataset represents email communication trends within a large European research institution. It records email exchanges between individuals over time, providing insights into the dynamics and organization of the communication network.

·       CiteSeer: The CiteSeer dataset is a citation network of scientific publications in the field of computer science. In this graph, each node represents a research paper, and edges denote citation relationships between papers. The documents are categorized into several predefined research topics, which are commonly used as ground-truth communities for evaluating community detection algorithms. 

·       CORA: The CORA dataset consists of a citation network of scientific publications in the domain of machine learning. Nodes correspond to individual papers, while edges represent citation links between them. Each paper is assigned to one of several subject categories, which serve as ground-truth communities. 

·       PubMed: The PubMed dataset is a citation network of biomedical research papers, particularly focusing on publications related to diabetes. In this network, nodes represent scientific articles and edges correspond to citation relationships. The papers are classified into three major categories according to the type of diabetes studied, which are often treated as ground-truth communities for evaluation purposes. 

·     DBLP: The DBLP dataset is a network of academic article citations, containing information about authors, titles, and publication venues. It is commonly used for tasks such as topic modelling, influence analysis, and author clustering.
