Prof.dr.ir. Arjen P. de Vries and prof. Djoerd Hiemstra lead the Information Retrieval research group at Radboud University, part of the Data Science section in the Institute for Computing and Information Sciences.
In OpenWebSearch.EU, we develop a new architecture for search engines where many parts of the system will be decentralized. The key idea is to separate index construction from the search engines themselves, where the most expensive step to create index shards can be carried out on large clusters while the search engine itself can be operated locally.
We also envision an Open-Web-Search Engine Hub, where companies and individuals can share their specifications of search engines and pre-computed, regularly updated search indices. We think of this as a search engine mash-up, that would enable a new future of human-centric search without privacy concerns.
