Machine Learning for Text Classification and Information Organization
ASIST Annual Meeting
Sunday, November 4, 2001, 9am-1pm


This timely half-day workshop will show you how to use machine learning successfully to categorize, filter, mine, and otherwise impose sense on online data. By automating not just the classification of text, but also the production of the classification rules themselves, machine learning can make classification practical in situations where purely manual indexing would be too slow or costly.

You Will Learn About

  • The major approaches to training text classification systems
  • Combining automated systems with manual classification in the most economical fashion
  • Evaluating commercial text classification offerings
  • Embedding text classification in larger systems
  • Making "build vs. buy" decisions
