Abstract

This chapter describes the Web Summaries system, which is designed to aid people in accomplishing exploratory Web research. Web Summaries enables users to produce automation artifacts, such as extraction patterns, relations, and personalized task-specific search templates, in the context of existing tasks. By leveraging the growing amount of structured Web pages and pervasive search capabilities, Web Summaries provides a set of semiautomatic interaction techniques for collecting and organizing personal Web content. First, it takes advantage of the growth in template material on the Web and designs semiautomatic interactive extraction of content from similar Web pages using structural and content extraction patterns. Second, it employs layout templates and user labeling to create rich displays of heterogeneous Web content collections. Third, it uses search technology for proactive retrieval of content from different, related Web sites through user-defined relations. Fourth, it let users define their own personalized and aesthetic views of heterogeneous content from any number of Web sites through cards. And finally, it introduces a new template-based search paradigm that combines the user-defined relations and cards into a search template. Search templates present a goal-driven search mechanism that creates visual personalized summaries of the content users need to accomplish their task.
