ACL/EACL 2001 Conference
Toulouse, France
July 6-7, 2001

Human language technologies promise solutions to challenges in human
computer interaction, information access, and knowledge management.
Advances in technology areas such as indexing, retrieval, transcription,
extraction, translation, and summarization offer new capabilities for
learning, playing and conducting business. This includes enhanced
awareness, creation and dissemination of enterprise expertise and know-how.

This workshop aims to bring together the community of computational
linguists working in a range of areas (e.g., speech and language
processing, translation, summarization, multimedia presentation, content
extraction, dialog tracking) both to report advances in human language
technology, their application to knowledge management and to establish a
road map for the Human Language Technologies for the next decade. The road
map will comprise an analysis of the present situation, a vision of where
we want to be in ten years from now, and a number of intermediate
milestones that would help in setting intermediate goals and in measuring
our progress towards our goals.

The workshop will be structured into two days, the first which will address
new research in human language technology for knowledge management that
addresses problems including but not limited to:

 * Expert Discovery: Modeling, cataloguing and tracking of distributed
 organizations and communities of experts.
 * Knowledge Discovery: Identification and classification of knowledge
 from unstructured multimedia data.
 * Knowledge Sharing: Awareness of and access to enterprise expertise and

Human language technology promises solutions to these challenges through
technologies such as:

 * Automated retrieval, extraction, and enrichment of information and
 knowledge from multimedia, multilingual, and multiparty information
 * Translingual or crosslingual retrieval, presentation, and sharing of
 * Automated detection and tracking of emerging topics from unstructured
 multimedia data (e.g., documents, web, video news broadcasts).
 * Use of knowledge sources to facilitate knowledge mapping and access
 (e.g., lexicosemantic such as Word-Net, semantic such as geospatial
 Gazetteers, semistructured such as thesauri, encyclopedia, fact books)
 * Automated question-answering from heterogeneous source
 * Intelligent tools that support the automated bibliometrics and
 document analysis/understanding in support of discovery of distributed
 experts and communities of expertise
 * Summarization and presentation generation of knowledge (e.g.,
 knowledge maps, lessons learned).
 * Modeling of user knowledge, beliefs, plans, (dis)abilities and
 preferences from queries, created artifacts, and human computer

The second day of the workshop will target the formulation and refinement
of a road map for the Human Language Technologies for the next decade.
Participants will help formulate grand challenge problems, discuss possible
data sets and/or evaluation metrics/methods that could form the basis of
more scientific methods, articulate the role of and necessary advances in
human language technology to solve these challenges, as well as identify
and characterize early innovations and issues (e.g., robustness,
scalability, ontology, privacy).

The target audience of the workshop includes active researchers,
developers, appliers/entrepreneurs and funders of human language technology
in general as well as how it is applied to knowledge management
applications. While we project a high degree of interest in this topic,
we intend to restrict attendance based upon the quality of paper
submissions to foster high quality interchange and progress.


This workshop is sponsored by the European Network of Excellence in Human
Language Technologies (ELSNET) who will be funding one or two invited


Both papers and demonstration submissions are encouraged, either on HLT in
general or its application to KM systems. Papers targeted at the first day
on HLT for KM should clearly articulate the knowledge management problem
addressed, the technical approach to solving that, the novelty of the
approach, its relation to previous work, the evaluation or performance of
the system or method, and discussion of limitations. Papers targeted at the
second day on human language technology direction should be authored so
they could be integrated into a more general HLT roadmap and so should
include a definition of the HLT area addressed (e.g., information
extraction, translation, speech recognition), a statement of the grand
challenges or problems in the subfield, an articulation/analysis of the
current state of the art, a vision of where the community wants to be in
ten years from now, a set of intermediate milestones that would help to set
intermediate goals and measure/evaluate progress toward these goals.

Submissions must be in English, no more than 8 pages long, and in the
two-column format prescribed by ACL'2001. Please see the ACL Style Guides
for the detailed guidelines. Submissions should be sent electronically in
Word (preferably) or PDF or ASCII text format to arrive no later than April
2, 2001 to Paula MacDonald ( As soon as possible,
authors are encouraged to send a brief email indicating their intention to
participate to include their contact information and the topic they intend
to address in their submission.

Submissions will be evaluated on the basis of their relevance, innovation,
quality, and presentation according to the schedule below.

 ACL/EACL 2001 Workshop


 6-7 July 2001
 Toulouse, France

 Sponsored by IBM, Endorsed by SIGGEN

- ----------------------------------------------------------------------
Natural language generation (NLG) constitutes the production of meaningful
texts in natural languages from some underlying non-linguistic
representation of information. Accomplishing this goal may be envisioned
for a number of different purposes, including standardized and/or
multi-lingual reports, summaries, machine translation, dialog applications,
and embedding in multi-media and hypertext environments. Consequently, the
automated production of language is associated with a large number of
highly diverse tasks whose appropriate orchestration in high quality poses
a variety of theoretical and practical problems. Relevant issues include
content selection, text organization, the production of referring
expressions, aggregation, lexicalization, and surface realization, as well
as coordination with other media.

This workshop is part of a bi-annual series of workshops about natural
language generation that runs since 1987. Previous European workshops have
been held at Royaumont, Edinburgh, Judenstein, Pisa, Leiden, Duisburg, and
Toulouse. The goal of the workshop is to be an informal meeting which
facilitates the dissemination of knowledge and expertise in the field. The
workshop will focus on the following topics:

 * Search methods for NLG (in content planning and realization)

 There seems to be a substantial discrepancy between
 application-oriented systems and principled approaches to NLG.
 Accomodating a standard pipeline architecture with suitable heuristic
 preferences to the intended functionality of a system stands in
 contrast to several principled approaches to searching which have been
 tried out so far. These include blackboard architectures, constraint
 propagation and, more recently genetic algorithms and statistical
 techniques. A comparison of these methods in terms of their potential
 and limitations is likely to improve understanding about this issue.
 Gained insights could prove fruitful for building applications in a
 more general and, thus, better reusable way, especially in large-scale
 applications such as summarization and machine translation.

 * Differences in information organization between source and
 presentation specifications (and methods to bridge between these)

 Whether the generation task is to verbally express contents of some
 knowledge base or to produce multi-lingual presentations from
 language-neutral or similar representations, there are strong
 similarities in building the target representations: In the
 overwhelming number of cases, the ordering and embedding of elements
 in the source representation is reflected by the ordering and
 embedding of their corresponding realizations at the surface. Often,
 this reflection is systematic, many times even simple. But a few cases
 prove complex and involve a major restructuring of the surface
 structure when compared to the source structure. A major emphasis of
 this topic is on collecting such complex cases, identifying
 commonalities between them and discussing restructuring techniques.

Accepted papers on these and related topics will be scheduled for
The majority of the time will be devoted to discussions, either in sequence
in parallel, depending on the number of participants. We are considering
organizing a panel. For the focus topics above, we will contact a number of
competent researchers to address the topic from a specific perspective
according to their experience. In addition, we will ask some of them to
prepare material / concrete examples for discussions.
