Paper accepts at ICML and KDD!

Some more good news!

Soon after our recent acceptance of our spoken English grading work at ACL, our work on learning models for job selection and personalized feedback gets accepted at the workshop Machine Learning for Education at ICML! Some results from this paper were discussed in one of our previous posts. The tool was built five years ago and has since helped a couple of million students get personalized feedback and aided 200+ companies hire better. I shall also be giving an invited talk at this workshop.

Earlier this month, we also got a paper at KDD accepted, which builds on our previous work in spontaneous speech evaluation. We find how well we can grade spontaneous speech of natives of different countries and also analyze the benefits the industry gets with such an evaluation system.

Busy year ahead it seems – paper presentations at France, Beijing, Australia and finally New Jersey, where we’re organizing the second edition of ASSESS, our annual workshop on data mining for educational assessment and feedback. It’s being organized at ICDM 2015 this winter. July 20th is the submission deadline for the workshop. Here is a list of submissions we saw in our workshop last year, at KDD. Spread the word!

Work on spoken English grading gets accepted at ACL, AM-R&D going to Beijing!

Good news! Our work on using crowdsourcing and machine learning to grade spontaneous English has been accepted at ACL 2015.

  • Ours is the first semi-automated approach to grade spontaneous speech.
  • We propose a new general technique which sits between completely automated grading techniques and peer grading: We use crowd for doing the tough human intelligence task, derive features from it and use ML to build high quality models.
  • We think, this is the first time anyone used crowdsourcing to get accurate features that are then fed into ML to build great models. Correct us if we are wrong!

The technique helps scale spoken English testing, which means super scale spoken English training!

Great job Vinay and Nishant.
