MyMobileSearch Project
The key goal of the MyMobileSearch project is to undertake R&D&I activities targeting the definition of mobile search technology capable of meeting the challenges set out. Note that the project will not try to define a totally new or revolutionary search technology but will define new formalisms and techniques to integrate and extend today´s browsers (page-rank, semantic browsers, etc.) to bring their results and performance into line with the requirements set by searches on the move.
