In this presentation, Peter will talk about the involvement of the web in the scientific process. He will attempt to contextualize this area within the field of web science and present four core research topics. These core topics are: (1) the development of an online infrastructure for researchers; (2) the appropriation of web tools for researchers; (3) the change in scientific practices and the open science movement; and (4) the analysis of data generated by researchers on the (social) web. He then will show results for each topic from two EU projects: STELLAR, a network of excellence in Technology Enhanced Learning; and TEAM, a Marie Curie project concerned with academic knowledge management. Peter will conclude with an outlook on the transformational potential of the web in science and research.
