Remote Participation

• Remote Participation via AdobeConnect
  • Join us on Wednesday morning 9 AM - Noon CST to hear our hackathon participants report back to the group and share their progress on parsing algorithms.
  • Please sign in 15 - 20 minutes early to learn how Adobe Connect works.
  • Help with AdobeConnect
  • Want to try your skills at parsing? Share your User Interface ideas? Got mad skills for developing image-analysis and image segmentation algorithms? Know where the great authority files (data dictionaries) are? Do tell, via remote participation or in our online group notes doc.

Overview of the Challenge

• 2013 iDigBio AOCR Hackathon Challenge
  • overall description of The Challenge
  • The Specific Task: parse OCR output to find values for these 2013 hackathon data elements
  • Metrics and Evaluation to be used
  • Three Data Sets
    • There are three data sets, that is, three different sets of images of museum specimen labels. Participants, working alone or in groups, may work on one or more data sets as they choose. The sets have been ranked, easy, medium, hard, as an estimate of how difficult it might be to successfully get good parsed data from the OCR output from each data set.
  • Accessing the Data

Frequently Asked Questions

• Hackathon FAQ
