The task is to implement a focused Web crawler component comprising an API and a Web-based GUI. The focused crawler's objective is to gather user-specified pieces of data from Web pages using two strategies: (1) by carrying out a set of Web search engine queries for user-provided query terms, by downloading Search Engine Result Pages, and optionally following the hyperlinks contained therein; and (2) using a set of user-provided seed URLs, by following the hyperlinks on the Web pages identified by these URLs, using a breadth-first search and a user-specified depth. Rather than implement from scratch, the project should be pursued as wrapping existing open-source components such as crawler libraries and Web search engine APIs with additional layers of functionality, and in some cases, providing a convenience layer that hides complexity. Skills/technologies: Java, Heritrix, WARC, search engine technology, crawling, Yahoo BOSS
