		 "Text Learning: Beyond Supervision"

		 Submission deadline: March 23, 2001


Due to the rapidly increasing amount of textual data available and the
range of interesting and important problems arising in text analysis,
there has been growing interest in applying machine learning
methods to text.  There has also been significant recent interest in
research that combines supervised and unsupervised learning.  This
research is especially relevant to text learning because the inherent
complexity of natural language usually requires models with many
parameters:  estimating those parameters requires a lot of data, and
obtaining labeled data is difficult and expensive.  By combining
unsupervised learning with supervised learning, the need for labeled
training data can often be greatly reduced, allowing for the
development of more powerful models and methods.

The workshop will explore machine learning methods for solving
supervised text learning tasks that exploit training methods beyond
straightforward supervised learning.

Relevant topics include:

* Text classification with labeled and unlabeled data: EM,
  co-training, transduction with SVMs, discriminative maximum entropy
  with unlabeled data.
* Information extraction with unlabeled data: bootstrapping,
  co-boosting.
* Part-of-speech tagging, parsing and other NLP with unlabeled data.
* Active learning: uncertainty sampling, query-by-committee, version
  space reduction.
* Model selection with unlabeled data.
* Word clustering for language modeling, distributional clustering,
  feature generation by clustering.
* Semi-supervised clustering, document clustering with user-feedback.
* Integrating prior knowledge into supervised learning, integrating
  distantly labeled data.
* Unsupervised methods for learning segmentation models, translation
  models, lexicons, etc.
* Link analysis for supervised learning.

The goal of this workshop is to bring together researchers from the
machine learning, information retrieval, computational linguistics and
language modeling to talk about their different perspectives and to
share their latest ideas.
