Relevance is seen as a relationship between a query and a resource, ignoring aspects of the user&#8217;s information need that are not explicit in the query. This contrasts with offline information seeking, where people frequently use social networks of known individuals as a source of information and as a basis for assessing its relevance. In this presentation I will outline our approach to personalised information seeking, based on computing trust relationships between the user and members of their social networks as a means to rank and filter resources. Results of an empirical study underlying this approach will be presented, followed by a demonstration of parts of the infrastructure through which our approach will be realised.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"http:\/\/stadium.open.ac.uk\/stadia\/preview.php?s=29&amp;whichevent=848\">Watch the webcast replay &gt;&gt;<\/a><\/p>\n\n\n\n<div class=\"wp-block-group\"><div class=\"wp-block-group__inner-container is-layout-constrained wp-block-group-is-layout-constrained\">\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.
