Track 4: Reverse Engineering Google's Page Rank Algorithm - A Classic Big Data Analytics Problem Solved with TwinFin In-Database Analytics
Speakers: Zach Marburger, Director of Online Marketing, Trident Marketing; Partha Sen, CEO, Fuzzy Logix; Russ Jones, CTO, Virante, Inc.

Ever since Sergey Brin and Larry Page created their first version of the Google search algorithm, understanding the factors that are used to rank web sites and their relative position in the results page has become one of the most significant analytics problem of our generation. Organizations spend millions of dollars each year in Search Engine Optimization techniques so that their pages show up high on Google's search engine results page. Google has kept its ranking algorithm a secret and keeps constantly refining and tuning it to keep hackers at bay. In this session, you will see a live demonstration of how Trident Marketing and Fuzzy Logix have used Netezza's predictive analytics capabilities to reverse engineer Google's page rank algorithm. They will show you how they identified the factors that are important in page ranking and how the weights of each of these factors have been derived.

Track 4: Completing the Picture: Moving from Big Data to Extreme Information - Sid Probstein, Attivio
Speaker: Sid Probstein, CTO, Attivio

Interest in analyzing and creating value from the deluge of customer, machine and sensor-generated data - log files, click streams, position data, etc. - is at an all time high. While analytic database management systems and massively parallel processing address the sheer volume of data, significant challenges still exist in their ability to handle the variety and complexity of information that can give you the complete picture that drives meaningful value. Consider all the other sources of information that contain important insights about employee, partner and customer behavior and opinions. There is a wealth of value that is today largely untapped by many organizations -- emails, open-ended survey questions, web forms, call logs, discussion boards, SharePoint and Wiki sites to name just a few.

Track 4: Hadoop and Netezza - Co-existence or Competition?
Speaker: Krishnan Parasuraman, Chief Architect, Digital Media & General Business, IBM Netezza

Hadoop is rapidly emerging as a viable platform for big data analytics. Thanks to early adoption by organizations like Yahoo and Facebook, and an active open source community, we have seen significant innovation around this platform. With support of relational constructs and a SQL-like query interface, many experts believe that Hadoop will subsume some of the data warehousing tasks at some point in the future. Even though Hadoop and parallel databases have some architectural similarities, they are designed to solve different problems. In this session, you will get introduced to Hadoop architecture, its salient differences from Netezza and typical use cases. You will learn about common co-existence deployment models that have been put into practice by Netezza's customers who have leveraged benefits from both these technologies. You will also understand Netezza's current support for Hadoop and future strategy.
