Project description
The Database Group of the University of Twente offers a job opening in the NWO Vidi Project “Distributed Information Retrieval by means of Keyword Auctions”.
The project’s aim is to distribute internet search functionality in such a way that communities of users and/or federations of small search systems provide search services in a collaborative way. Instead of getting all data to a centralized point and process queries centrally, as is done by today’s search systems, the project will distribute queries over many small autonomous search systems and process them locally.
In this project, the PhD student will research a new approach to distribute search: distributed information retrieval by means of keyword auctions. Keyword auctions like Google’s AdWords give advertisers the opportunity to provide targeted advertisements by bidding on specific keywords. Analogous to these keyword auctions, local search systems will bid for keywords at a central broker. They “pay” by serving queries for the broker. The broker will send queries to those local search systems that optimize the overall effectiveness of the system, i.e., local search systems that are willing to serve many queries, but also are able to provide high quality results.
The PhD student will work within a small team of researchers that approaches the problem from three different angles:
1. | modeling the local search system, including models for automatic bidding and multi-word keywords |
2. | modeling the search broker’s optimization using the bids, the quality of the answers, and click-through rates |
3. | integration of structured data typically available behind web forms of local search systems with text search |
The approaches will be evaluated using prototype systems and simulations on benchmark test collections.
The proposed research will be done in co-operation with several important players in the search and peer-to-peer markets. Together with Yahoo Research. the University of Twente runs the project “Radical Decentralization of Search”. With, WCC Smart Search and Match the University of Twente collaborates on “Federated search on user-enhanced data”. At Delft University, the Information and Communication Theory group investigates “Collaborative Search and Recommendation in P2P Systems” in Tribler.
