Query: LEAN-LIFE: A Label-Efficient Annotation Framework Towards Learning from
  Explanation   Successfully training a deep neural network demands a huge corpus of labeled
data. However, each label only provides limited information to learn from and
collecting the requisite number of labels involves massive human effort. In
this work, we introduce LEAN-LIFE, a web-based, Label-Efficient AnnotatioN
framework for sequence labeling and classification tasks, with an easy-to-use
UI that not only allows an annotator to provide the needed labels for a task,
but also enables LearnIng From Explanations for each labeling decision. Such
explanations enable us to generate useful additional labeled data from
unlabeled instances, bolstering the pool of available training data. On three
popular NLP tasks (named entity recognition, relation extraction, sentiment
analysis), we find that using this enhanced supervision allows our models to
surpass competitive baseline F1 scores by more than 5-10 percentage points,
while using 2X times fewer labeled instances. Our framework is the first to
utilize this enhanced supervision technique and does so for three important
tasks -- thus providing improved annotation recommendations to users and an
ability to build datasets of (data, label, explanation) triples instead of the
regular (data, label) pair.
