ALIGNED will develop new ways to build and maintain IT systems that use big data on the web. ALIGNED brings together world class computer science researchers (TCD, Oxford, Leipzig), software companies specialised in data-intensive systems (Semantic Web Company), information companies (Wolters Kluwer Germany) and academic curators of Seshat: Global History Databank, large datasets describing world history and archaeology (Oxford, Poznan). Together they will create more efficient methods of building IT systems that extract, process, publish and share web data. This will lay the foundations for the next generation of big data systems that lower costs and deal with the web data challenges of dynamism, complexity, scale and inconsistency. ALIGNED is coordinated by the School of Computer Science and Statistics at Trinity College Dublin and is an associated project of the Science Foundation Ireland ADAPT research centre.
