Modeling IT support organizations from transactional logs

Claudio Bartolini, Cesare Stefanelli, Mauro Tortonesi
2010 2010 IEEE Network Operations and Management Symposium - NOMS 2010  
This paper presents an experimental analysis of transaction logs from a real-life IT support organization, provided to us by the Outsourcing Services Division of HP.  ...  However, the complexity of real-life IT support organizations makes it extremely hard to model their organizational, structural and behavioral processes.  ...  The statistical analysis of transactional logs from the BailUsOut IT support organization allows us to make some interesting considerations.  ...

Semantic Technology for Capturing Communication Inside an Organization

Marko Grobelnik, Dunja Mladenic, Blaž Fortuna
2009 IEEE Internet Computing  
The idea is to support knowledge management in analyzing communication between people in an organization.  ...  We propose an approach consisting of five major steps that enable transformation of the data from a given e-mail transactions recordings to a light-weight ontology estimating structure of the organization  ...  In particular, we show an example of modeling internal communication of an organization (reflecting its organizational structure) from its e-mail server log files.  ...
