1 Building an IT Taxonomy with Cooccurrence Analysis, Hierarchical Clustering, and Multidimensional Scaling Chia-jung Tsui, Ping Wang, Kenneth R. Fleischmann, Asad B. Sayeed, Amy Weinberg, and Douglas Oard The abundance of IT is a challenges for both IT management & information management. Cartoon by Sidney Harris

3 Extant Approach to IT Taxonomy Compile list of ITs by empirical surveys. Experts rate ITs according to their assessments of functions or features of the technologies. Limitations Narrow representation: arbitrary and limited choices of features and functions, few ITs Static: snapshots few and far in between Not scalable: more ITs lower reliability 5 Scalable Computational Approach Downloaded full-text articles published in from six magazines: ComputerWorld & InformationWeek BusinessWeek & The Economist Newsweek & US News and World Report Extracted ~220,000 paragraphs containing 50 IT concepts. 6

Counted co-occurrence of IT concepts in paragraphs. 8

5 Co-Occurrence of IT Concepts Over the past few years, we have seen the ERP vendors-led by SAP-move into different business areas, says Byron Miller, an analyst with the Giga Information Group. The competitive advantage of just having ERP has diminished. The next big thing beyond ERP is supply-chain management. Links between groupware and ERP applications speed users' access from within a groupware application to key business data, such as purchase orders, inventory, customer histories, and other supply-chain information. 9 Hierarchical Clustering Cluster 1 Cluster 2 Cluster 3 Cluster 4 Cluster 5 Cluster 6 Cluster 7 Cluster 8

8 Implications for IT Management When expert knowledge is not readily available, this approach offers maps of IT domains or sub-domains. A new technology s cluster membership may suggest its broader type. Taxonomy is useful for vendors in product/service labeling and for adopters in IT portfolio management. 15 Takeaways Computational discourse analysis based on co-occurrence and hierarchical clustering can help us explore complex relationships among IT concepts in a representative, dynamic, and scalable way. Social-technical approach: we used social artifacts (language/discourse) to chart technological terrains. Effective information management and effective IT management go hand-in-hand. 16
