Monitoring network structure and content quality of signal processing articles on wikipedia

Wikipedia has become a widely-used resource on signal processing. However, the freelance-editing model of Wikipedia makes it challenging to maintain a high content quality. We develop techniques to monitor the network structure and content quality of Signal Processing (SP) articles on Wikipedia. Using metrics to quantify the importance and quality of articles, we generate a list of SP articles on Wikipedia arranged in the order of their need for improvement. The tools we use include the HITS and PageRank algorithms for network structure, crowdsourcing for quantifying article importance and known heuristics for article quality.
