In this talk, I will discuss how to obtain useful information and knowledge from the web data and the search log data, and how to use such data to build killer applications. Web-scale data and the so-called peta-byte age is changing many aspects of business practice and scientific research. On the science frontier, it challenges methodologies in many established fields including statistics, machine learning, natural language processing, etc. However, a fundamental challenge we are facing is that web data is noisy and it is only good for “head queries”. I will use some results from a system we recently built to demonstrate the challenges and opportunities in this field.
