Abstract
There is a growing recognition among MIS researchers and practitioners that social media provide a valuable source of business intelligence. Unearthing relevant and useful information among the voluminous postings remains a challenge, however. Automated methods based on text mining have made significant progress in recent years by discovering a variety of new methods and features. This study adds to this stream by introducing a novel text mining procedure centered around numerical expressions contained in text documents. In this method, numerical expressions are extracted, categorized, and binned, and their presence and magnitude are stored as document features. We demonstrate, using a case study from the automotive industry, that numerical expressions can be reliably identified, and that these numerical features enable improvements in document classification. As an extension to this case study, we contribute a decision support system for managing product quality using both textual and numerical attributes.
