Multilingual Summarization Evaluation

Workshop Description

This one-day workshop will focus on the challenges that the Summarization and QA
communities face in developing useful systems and in developing evaluation
measures. Our aim is to bring these two communities together to discuss the
current challenges and to learn from each other's approaches, following the
success of a similar workshop held at ACL-05, which brought together the Machine
Translation and Summarization communities.

A previous summarization workshop (Text Summarization Branches Out, ACL-04)
targeted the exploration of different scenarios for summarization, such as small
mobile devices, legal texts, speech, dialog, email and other genres. We
encourage a deeper analysis of these, and other, user scenarios, focusing on the
utility of summarization and question answering for such scenarios and genres,
including cross-lingual ones.

By focusing on the measurable benefits that summarization and question answering
has for users, we hope one of the outcomes of this workshop will be to better
motivate research and focus areas for summarization and question answering, and
to establish task-appropriate evaluation methods. Given a user scenario, it
would ideally be possible to demonstrate that a given evaluation method predicts
greater/lesser utility for users. We especially encourage papers describing
intrinsic and extrinsic evaluation metrics in the context of these user scenarios.

Both summarization and QA have a long history of evaluations: Summarization
since 1998 (SUMMAC) and QA since 1999 (TREC). The importance of summarization
evaluation is evidenced by the many DUC workshops; in DUC-05, extensive
discussions were held regarding the use of ROUGE, ROUGE-BE, and the pyramid
method, a semantic-unit based approach, for evaluating summarization systems.
The QA community has related evaluation issues for answers to complex questions
such as the TREC definition questions. Some common considerations in both
communities include what constitutes a good answer/response to an information
request, and how does one determine whether a ''complex'' answer is sufficient?
In both communities, as well as in the distillation component of the 2005 DARPA
program GALE, researchers are exploring how to capture semantic equivalence
among components of different answers (nuggets, factoids or SCUs). There also
have been efforts to design new automatic scoring measures, such as ROUGE-BE and
POURPRE. We encourage papers discussing these and other metrics that report on
how well the metric correlates with human judgments and/or predicts
effectiveness in task-focused scenarios for summarization and QA.

This workshop is a continuation of ACL 2005 for the summarization community, In
which those interested in evaluation measures participated in a joint Workshop
on evaluation for summarization and MT. As a sequel to the ACL 2005 workshop, in
which the results of the first Multilingual multi-document summarization
evaluation (MSE) were presented
(http://www.isi.edu/~cyl/MTSE2005/MLSummEval.html), we plan to report and
discuss the results of the 2006 MSE evaluation.

In summary, we solicit papers on any or all of the following three

- Task-based user scenarios requiring question answering
(beyond factoids/lists) and/or summarization, across genres and
- Extrinsic and intrinsic evaluations, correlating extrinsic measures
outcome of task completion and/or intrinsic measures with human
previously obtained.
- The 2006 Multilingual Multi-document Summarization Evaluation

Anyone with an interest in summarization, QA and/or evaluation is encouraged to
participate in the workshop. We are looking for research papers in the
aforementioned topics, as well as position papers that identify limitations in
current approaches and describe promising future research directions.

SUMMARIZATION TASK: Multilingual Summarization Evaluation

Details for MSE 2006 will be available soon at

For description and results of last year's MSE task, please see:

Send email to lucy.vanderwendemicrosoft.com to be added to MSE


Papers should be no more than 8 pages, formatted following the guidelines that
will be made available on the conference Web site. The reviewing process will be
blind, so authors' names, affiliations, and all self-references should not be
included in the paper. Authors who cannot submit a PDF file electronically
should contact the organizers at least one week prior to the May 1st deadline.

Proceedings will be published in conjunction with the main HLT/NAACL

Details on how to submit your paper available on the website or by
the organizers.

*Second Announcement*

7th SIGdial Workshop on Discourse and Dialogue
Sydney, July, 15-16, 2006

Continuing with a series of successful workshops in Hong Kong,
Aalborg, Philadelphia, Sapporo and Lisboa this workshop spans the ACL
and ISCA SIGdial interest area of discourse and dialogue. This series
provides a regular forum for the presentation of research in this area
to both the larger SIGdial community as well as researchers outside
this community. The workshop is organized by SIGdial, which is
sponsored jointly by ACL and ISCA.

Topics of Interest

We welcome formal, corpus-based, implementational or analytical work
on discourse and dialogue including but not restricted to the
following three themes:

1. Discourse Processing and Dialogue Systems

Discourse semantic and pragmatic issues in NLP applications such as
text summarization, question answering, information retrieval
including topics like:

* Discourse structure, temporal structure, information structure
* Discourse markers, cues and particles and their use
* (Co-)Reference and anaphora resolution, metonymy and bridging
* Subjectivity, opinions and semantic orientation

Spoken, multi-modal, and text/web based dialogue systems including
topics such as:

* Dialogue management models;
* Speech and gesture, text and graphics integration;
* Strategies for preventing, detecting or handling
miscommunication (repair and correction types, clarification and
under-specificity, grounding and feedback strategies);
* Utilizing prosodic information for understanding and for

2. Corpora, Tools and Methodology

Corpus-based work on discourse and spoken, text-based and multi-modal
dialogue including its support, in particular:

* Annotation tools and coding schemes;
* Data resources for discourse and dialogue studies;
* Corpus-based techniques and analysis (including machine
* Evaluation of systems and components, including methodology,
metrics and case studies;

3. Pragmatic and/or Semantic Modeling

The pragmatics and/or semantics of discourse and dialogue (i.e. beyond
a single sentence) including the following issues:

* The semantics/pragmatics of dialogue acts (including those which
are less studied in the semantics/pragmatics framework);
* Models of discourse/dialogue structure and their relation to
referential and relational structure;
* Prosody in discourse and dialogue;
* Models of presupposition and accommodation; operational models
of conversational implicature.

Submission of Papers and Abstracts

The program committee welcomes the submission of long papers for full
plenary presentation as well as short papers and demonstrations. Short
papers and demo descriptions will be featured in short plenary
presentations, followed by posters and demonstrations.

* Long papers must be no longer than 8 pages, including title,
examples, references, etc. In addition to this, two additional
pages are allowed as an appendix which may include extended
example discourses or dialogues, algorithms, graphical
representations, etc.
* Short papers and demo descriptions should aim to be 4 pages or
less (including title, examples, references, etc.)

Papers that have been or will be submitted to other meetings or
publications must provide this information (see submission
format). SIGdial 06 cannot accept for publication or presentation work
that will be (or has been) published elsewhere.

Authors are encouraged to make illustrative materials available, on
the web or otherwise. For example, excerpts of recorded conversations,
recordings of human-computer dialogues, interfaces to working systems,
