My first debt of gratitude must go to my advisor, Jamie Callan, for taking me on as a student and for leading me through many aspects of my academic career. ...
This experience has been extremely valuable to me and I will treasure it for the rest of my life. ...
For example, resource selection algorithms need source size estimates to adjust (normalize) the information source selection scores for accommodating the widely varying information source size distributions ...

This paper presents a unified utility framework for resource selection of distributed text information retrieval. ...
This new model provides a more solid framework for distributed information retrieval. Empirical studies show that it is at least as effective as other state-of-the-art algorithms. ...
Distributed document retrieval is a more sophisticated task. It selects relevant information sources for users' queries as the database recommendation system does. ...

We conclude with a summary of future plans for its large scale deployment, testing and evaluation within this context. ...
Introduction For over ten years, research in Distributed Information Retrieval (DIR) has sought efficient and effective ways of retrieving intellectual content which is distributed across internetworked ...

Federated search (federated information retrieval or distributed information retrieval) is a technique for searching multiple text collections simultaneously. ...
For each query, a subset of collections that are most likely to return relevant documents are selected. This creates the collection selection problem. ...
Acknowledgements The authors are grateful to Jamie Callan and reviewers for their insightful comments. ...

In this environment of uncooperative data sources, we study the problem of federated entity search, where redundant information about entities is reduced on-the-fly through entity consolidation performed ...
These entities reside in different sources, which may provide only limited information about their content and are therefore called "uncooperative". ...
Distributed document retrieval for uncooperative environments has been studied in the IR community [8, 9] . ...

The German Vascoda project provides this service for dozens of information sources. ...
Currently, however, the Vascoda portal is based on a non-cooperative metasearch approach, where results from sources are merged randomly and ranking quality is sub-optimal. ...
In general, we can divide distributed search environments into two categories: uncooperative, isolated environments (metasearch) and cooperative, integrated environments (federated search). ...
