CS249 Course by Professor John (Junghoo) Cho
The advent of powerful personal computers and the Internet resulted in exponential growth in digital information. Anyone can create rich contents using his or her own personal computer and make it available on the Web. Many high-quality data sources are also available online within a single click of mouse.

The growth of digital information, however, has brought in tremendous challenges in managing, organizing and accessing such information. The inherent heterogeneity of the information as well as the wide variety of unstructured text, semistructured, and structured data make it challenging to handle them. In this course, we will go over research papers to study the main approaches that people have taken to manage information on the Internet. In particular, the class will be structured around three major themes: 1) Data extraction approach 2) Central indexing approach and 3) Dynamic integration approach.
