Recommender&nbsp;Systems can serve dual purpose. To researchers, it can help them to stay in touch with the&nbsp;latest developments in their field. To authors, it can broaden their audiences resulting in&nbsp;increased number of reads and therefore more effective dissemination of knowledge.&nbsp;Citation Proximity Analysis (CPA) is based on the Co-Citation approach and the underlying&nbsp;heuristic of CPA is that the closer the documents are cited together the more likely they are&nbsp;related. In this work, a step by step scalable approach is developed for building CPA-based&nbsp;recommender systems. In this approach, three new novel proximity functions are introduced,&nbsp;extending the basic assumption of Co-Citation analysis to take the distance between the cocited documents into account. A CPA based recommender system was built from a corpus of more than 350,000 full-texts articles and a user survey was conducted to perform an initial&nbsp;evaluation. And, two of our three proximity functions used within CPA outperformed CoCitation based baseline approach by 25%.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"http:\/\/stadium.open.ac.uk\/stadia\/preview.php?s=29&amp;whichevent=2961\">Watch the webcast replay &gt;&gt;<\/a><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"> <a href=\"https:\/\/schools.stem.open.ac.uk\/knowledge-media-institute\/past-seminars\/\">View all past events<\/a><\/p>\n\n\n\n<div class=\"wp-block-group is-nowrap is-layout-flex wp-container-core-group-is-layout-8f761849 wp-block-group-is-layout-flex\">\n<figure class=\"wp-block-image size-full has-custom-css wp-custom-css-ac9b5317\"><img loading=\"lazy\" decoding=\"async\" width=\"213\" height=\"246\" src=\"https:\/\/schools.stem.open.ac.uk\/knowledge-media-institute\/wp-content\/uploads\/sites\/8\/2026\/07\/image-2.png\" alt=\"Maven of the Month\" class=\"wp-image-537\"\/><\/figure>\n\n\n\n<div class=\"wp-block-group is-vertical is-layout-flex wp-container-core-group-is-layout-4fc3f8e1 wp-block-group-is-layout-flex\">\n<h3 class=\"wp-block-heading\"><a href=\"https:\/\/schools.stem.open.ac.uk\/knowledge-media-institute\/maven-of-the-month\/\">Maven of the Month<\/a><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">We are also inviting top experts in AI and Knowledge Technologies to discuss major socio-technological topics with an audience that comprises both members of the Knowledge Media Institute, as well as the wider staff at The Open University.
