Analyzing Large Collections of Electronic Text Using OLAP [article]

Steven Keith, Owen Kaser, Daniel Lemire
2006 arXiv   pre-print
Computer-assisted reading and analysis of text has various applications in the humanities and social sciences.  ...  By storing text analysis information in an OLAP system, a user can obtain solutions to inquiries in a matter of seconds as opposed to minutes, hours, or even days.  ...  OLAP is especially applicable when many aggregate queries such as sum and average are of interest. Thus, data warehouses and OLAP have been used widely in business applications.  ...
