The 2008 Intternational Semantic Web Conference Doctoral Consortium (DC) allows PhD students to present their work and obtain guidance from mentors as well as interact with other postgraduate students. Students who submit papers to the main conference are also invited to apply to the DC. All papers submitted to the DC track will undergo a thorough reviewing process with a view to providing detailed and constructive feedback. The best submissions will be selected for presentation at the ISWC 2008 DC sessions. Five page papers will be published in the main ISWC proceedings. The deadline for submissions is May 16. The ISWC 2008 DC is chaired by Diana Maynard.
