Dr. Lillian N. Cassel. Overview of the class. Purpose: Course Description. How do they do that?  Many web applications, from Google to travel sites to resource . collections, . present results found by crawling the Web to find specific materials of interest to the application theme.  Crawling the Web involves technical issues, politeness conventions, characterization of materials, decisions about the breadth and depth of a search, and choices about what to present and how to display results.  This course will explore all of these issues.  In addition, we will address what happens after you crawl the web and acquire a collection of pages.  You will decide on the questions, but some possibilities might include these:  What summer jobs are advertised on web sites in your favorite area?  What courses are offered in most (or few) computer science departments?  What theatres are showing what movies?  etc?   Students will develop a web site built by crawling at least some part of the web to find appropriate materials, categorize them, and display them effectively.  Prerequisites: some programming experience: CSC 1051 or the equivalent..
