Scalable Web Data Extraction for Online Market Intelligence

Abstract:
Online market intelligence (OMI), and, especially, competitive intelligence for product pricing, is a very important application area for Web data extraction. However, OMI presents nontrivial challenges to data extraction technology.

Sophisticated and highly parameterized navigation and extraction tasks are required. Data cleansing on the fly is necessary in order two identify identical products from different suppliers. It must be possible to smoothly define data flow scenarios that merge and filter streams of extracted data stemming from several Web sites and store the resulting data into a data warehouse, where the data are subjected to market intelligence analytics. Finally, the system must be highly scalable so to extract and process massive amounts of data in a short time. Lixto (www.lixto.com), a company offering data  tools and services, has been providing OMI solution for several customers. In this talk it is shown how Lixto has tackled each of the above challenges by improving and extending its original data extraction software.

Most importantly, we show how high scalability is achieved through cloud computing. The talk also features case studies in different application domains. Joint work with Robert Baumgartner and Marcus Herzog.
