Valdis Krebs is an American-Latvian researcher, author, and consultant in the field of social and organizational network analysis. He is the founder and chief scientist of OrgNet, LLC, and the creator of InFlow software, which in 2008 Wired Magazine called one of the most advanced tools for analyzing and visualizing networks. [1] Popular Science has described Krebs as a "leading expert" [2] and a "pioneer" of network analysis, [3] while Military.com's DefenseTech blog has called him a leading authority in the field. [4]
After the September 11 attacks, Krebs used public information and newspaper clippings to produce a partial map of the organization behind the attacks. The resulting paper, Uncloaking Terrorist Networks, has been called a classic, and "likely the most cited public analysis of the 9/11 network." [5] After publishing it, he was "invited to Washington to brief intelligence contractors." [6]
Since 2004 Krebs has periodically published infographics showing the political polarization of American book-buying patterns. [7] [8] He has claimed that the web leads people to narrower, more extreme viewpoints [1] (similar to the "bubble effect"), and suggests cultivating diversity in social networks, [9] a process he calls "network weaving". [10]
Krebs has used social network maps to provide evidence of corruption, [11] help a non-profit group prosecute a slumlord conspiracy, [12] and visualize the "ecosystem" of fraud in the Bernie Madoff Ponzi scheme scandal. [13] He has also consulted for corporate clients including IBM and Google. [11]
Social network analysis (SNA) is the process of investigating social structures through the use of networks and graph theory. It characterizes networked structures in terms of nodes and the ties, edges, or links that connect them. Examples of social structures commonly visualized through social network analysis include social media networks, memes spread, information circulation, friendship and acquaintance networks, business networks, knowledge networks, difficult working relationships, social networks, collaboration graphs, kinship, disease transmission, and sexual relationships. These networks are often visualized through sociograms in which nodes are represented as points and ties are represented as lines. These visualizations provide a means of qualitatively assessing networks by varying the visual representation of their nodes and edges to reflect attributes of interest.
Logic Programming Associates (LPA) is a company specializing in logic programming and artificial intelligence software. LPA was founded in 1980 and is widely known for its range of Prolog compilers and more recently for VisiRule.
The Information and Communications Laboratory (ICL) is one of eight labs in the Georgia Tech Research Institute. Along with the GTRI Cyber Technology and Information Security Laboratory, it is part of the Information and Cyber Sciences directorate. It conducts a broad range of research in areas of computer science, information technology, communications, networking, and the development of commercial products from university research.
Social network analysis software is software which facilitates quantitative or qualitative analysis of social networks, by describing features of a network either through numerical or visual representation.
Jacob Ezra Merkin is an American investor, hedge fund manager and philanthropist. He had been a fund manager and capital raiser until 2008 when one of the funds in Gabriel Capital LP, his $5 billion group of hedge funds became insolvent because a large portion of its assets was invested with the convicted Ponzi scheme operator Bernard Madoff. The fallout from his investment with Madoff has been extensive. He navigated a series of lawsuits without a finding of fraud or knowledge of the scheme, but agreed to repay any fees earned from the investment in Madoff historically. He had to resign a series of positions including his role as Non-executive Chairman of GMAC.

Computational journalism can be defined as the application of computation to the activities of journalism such as information gathering, organization, sensemaking, communication and dissemination of news information, while upholding values of journalism such as accuracy and verifiability. The field draws on technical aspects of computer science including artificial intelligence, content analysis, visualization, personalization and recommender systems as well as aspects of social computing and information science.
Hsinchun Chen is the Regents' Professor and Thomas R. Brown Chair of Management and Technology at the University of Arizona and the Director and founder of the Artificial Intelligence Lab. He also served as lead program director of the Smart and Connected Health program at the National Science Foundation from 2014 to 2015. He received a B.S. degree from National Chiao Tung University in Taiwan, an MBA from SUNY Buffalo and an M.S. and Ph.D. in Information Systems from New York University.
The Cyberinfrastructure for Network Science (CNS) Center was founded in October 2005 by Professor Katy Börner at Indiana University, Bloomington. It emerged from the Information Visualization Lab at IU that focused on the analysis and visualization of data since 1999. With the advent of CNS, the mission was broadened from providing a research lab to building an entity that would advance datasets, tools, and services for the study of biomedical, social and behavioral science, physics, and other networks. A specific focus of CNS is research on the structure and evolution of science and technology (S&T) and the communication of results via science maps.
In network theory, link analysis is a data-analysis technique used to evaluate relationships (connections) between nodes. Relationships may be identified among various types of nodes (objects), including organizations, people and transactions. Link analysis has been used for investigation of criminal activity, computer security analysis, search engine optimization, market research, medical research, and art.
