The primary focus of Web information retrieval support systems (WIRSS) are to address the aspects of search that consider the specific needs and goals of the individuals conducting Web searches. WIRSS moves beyond the traditional focus of automated searching within digital collections, applying intelligent methods and Web-based technologies to assist users in specifying their information needs, evaluating and exploring search results, and managing the information they find. The goal of this paper is to provide an overview of some of the key issues, challenges, and opportunities in WIRSS research.
