			Second Call for Papers

	Workshop on Reading Comprehension Tests as Evaluation for
		Computer-Based Language Understanding Systems

	    Thursday, May 4th, 2000, Seattle, Washington, USA
	(post-conference workshop in conjunction with ANLP-NAACL2000)


Reading Comprehension tests, such as the one below, are designed to help
evaluate a reader's understanding of a text passage.

  How Maple Syrup is Made

  Maple syrup comes from sugar maple trees.  At one time, maple
  syrup was used to make sugar.  This is why the tree is called a
  "sugar" maple tree.

  Sugar maple trees make sap.  Farmers collect the sap.  The best
  time to collect sap is in February and March.  The nights must be
  cold and the days warm.

  The farmer drills a few small holes in each tree.  He puts a
  spout in each hole.  Then he hangs a bucket on the end of each
  spout.  The bucket has a cover to keep rain and snow out.  The sap
  drips into the bucket.  About 10 gallons of sap come from each
  hole.

  1. Who collects maple sap?                 (Farmers)
  2. What does the farmer hang from a spout? (A bucket)
  3. When is sap collected?                  (February and March)
  4. Where does the maple sap come from?     (Sugar maple trees)
  5. Why is the bucket covered?              (to keep rain and snow out)

Such tests exist in many languages, have human performance benchmarks
associated with them, and come in a variety of types (short-answer,
multiple choice) and levels of difficulty.  In addition, they are
generally written to make each story and set of questions
self-contained, in order to require as little outside knowledge as
possible to answer the questions.

The focus of the proposed workshop will be to explore the following
questions:

- Can such exams be used to evaluate computer-based language
  understanding effectively and efficiently?
- Would they provide an impetus and test bed for interesting and
  useful research?
- Are they too hard for current technology?
- Or are they too easy, such that simple hacks can score high,
  although there is clearly no understanding involved?

The most direct method of exploring these questions is to choose a set
of tests and build a system that takes these tests.  Some preliminary
results indicate that such tests are tractable, but not trivial and
that linguistic processing is helpful (Hirschman, et al. ACL-99).  A
test set, evaluation routines, prototype system, and documentation are
available upon request to light at mitre.org.

We hope that a number of submissions will present results based on
actual reading comprehension systems.  In addition, we encourage
submissions that report on other kinds of tests or similar tests in
other languages, or that address our list of questions by other
means.  Note that submissions are encouraged that describe work in
progress with preliminary empirical results.

Format for Submission

Authors are asked to submit previously unpublished papers only; a
workshop proceedings will be published. Our target submission length
is 2000 words but both shorter and longer submissions will also be
considered.  Electronic submission of postscript will be accepted.
Hard copy submissions should include 4 copies of the paper. Since the
papers will be reviewed anonymously, please do not place the author
name on the paper. Instead include a separate title page with title,
abstract, author, and e-mail address. Unless requested otherwise,
notification of acceptance will be sent electronically to the first
author.  Parallel submission is unproblematic; however if your paper
is accepted to this workshop and you decide to present it here, we
will ask you to withdraw it from any other events.

Important Dates

Deadline for submission: February 11th, 2000
Notification of authors: March    1st,  2000
Final versions due:      March    10th, 2000

(The mailing list, read-comp at linus.mitre.org, has been set up to
discuss reading comprehension tests as evaluation for computer-based
language understanding systems.  It is open subscription and
unmoderated. To subscribe, send email to majordomo at linus.mitre.org
with 'subscribe read-comp' in the body.)
