MEMPHIS, TN—July 1, 2019. Dr. Srikar Velichety, Assistant Professor of Business Information and Technology at the Fogelman College of Business and Economics at the University of Memphis recently published, "Quality Assessment of Peer-Produced Content in Knowledge Repositories using Development and Coordination Activities." The paper is co-authored by Professors Sudha Ram (University of Arizona) and Jesse Bockstedt (Emory University).

Open source knowledge repositories, such as Wikipedia, face continuous skepticism from critics who question the validity of their content and firm believers who accept their global impact on legal, medical and financial entities. With over fifty services on the Internet that host free access web-collections, the assessment of content on these knowledge repositories is vital to maintaining their integrity, use and acceptance.

In this published paper, Dr. Velichety and co-authors develop a process to identify relevant features for quality assessment models and algorithms for processing datasets in large-scale knowledge repositories. Models using these features, on English language Wikipedia articles, outperform existing methods for quality assessment with an overall accuracy of 81%. "There are significant improvements to precision and recall values too which indicate the validity of our models in both assessing the content accurately and for a wide variety of topics which is ideal for those accessing and using these knowledge repositories. In addition, we showed that this can be done efficiently and regularly on a large scale with minimal infrastructure requirements which is critical considering the high frequency with which content is updated on these repositories" said Dr. Velichety.

Research scholars, data scientists and big data users will find the paper extensive and thorough. The full article can be accessed here.
