Second Pascal Challenge on
Large Scale Hierarchical Text classification
Web site: http://lshtc.iit.demokritos.gr/
Email: lshtc_info(at)iit.demokritos.gr
Following a successful first edition, we are pleased to announce the 2nd
edition of the Large Scale Hierarchical Text Classification (LSHTC) Pascal
Challenge. The LSHTC Challenge is a hierarchical text classification
competition, using large datasets. This year’s challenge will increase the
scale and the difficulty of the task, using data from Wikipedia
(www.wikipedia.org), in addition to the ODP Web directory data
(www.dmoz.org).
Hierarchies are becoming ever more popular for the organization of text
documents, particularly on the Web. Web directories and Wikipedia are two
examples of such hierarchies. Along with their widespread use, comes the
need for automated classification of new documents to the categories in the
hierarchy. As the size of the hierarchy grows and the number of documents to
be classified increases, a number of interesting machine learning problems
arise. In particular, it is one of the rare situations where data sparsity
remains an issue, despite the vastness of available data: as more documents
become available, more classes are also added to the hierarchy, and there is
a very high imbalance between the classes at different levels of the
hierarchy. Additionally, the statistical dependence of the classes poses
challenges and opportunities for the learning methods.
The challenge consists of three categorization tasks, involving different
documents and category systems. In particular, the largest category system,
based on Wikipedia, contains more than 300,000 categories and 2M documents
for training. The largest category system ever used in the past for
evaluation purposes, to the best of our knowledge, was based on the Yahoo!
Directory and contained 130,000 categories and 500,000 training documents.
In addition to the largest task, two smaller ones, based on Wikipedia and
DMOZ respectively, are included in the challenge. The scale of these is in
the order of the first edition of the challenge. All of the datasets in this
edition are multi-label. Particularly in the two datasets that are based on
Wikipedia, each document is assigned on average to 3.2 and 4.6 categories
respectively. Furthermore, the hierarchies are no longer simple tree
structures, as both documents and subcategories are allowed to belong to
more than one other category. More information regarding the tasks and the
challenge rules can be found at the challenge’s Web site; follow the “Tasks,
Rules and Guidelines” link.
As in the first edition, participants will be able to smoothly and
continuously submit runs, in order to improve their systems. This year we
also plan a two-stage evaluation of the participating methods: one measuring
classification performance and one for computational performance. It is
important to measure both, as they are dependent. The results will be
included in a final report about the challenge and we also aim at organizing
a special ECML’11 workshop.
In order to register for the challenge and gain access to the datasets you
must have an account at the challenge Web site.

=====================================
There is a strong interest in fields like computer vision, audio
processing, multimedia, HCI, and pervasive computing, in designing
computational models of human interaction in realistic social settings.
Such interest is boosted by the increasing capacity to acquire
behavioral data with cameras, microphones and other fixed and mobile
sensors. Unlike the traditional HCI view, which emphasizes communication
between a person and a computer, the emphasis of an emerging body of
research has been shifting towards communicative social behavior in
natural situations, with examples such as informal conversational
settings, general workplace environments, interviews, and meeting
scenarios.
The workshop will gather, discuss, and disseminate unpublished work on
computational models and systems for the analysis of social behavior.
Given the scope of Automatic Face and Gesture Recognition conference, we
would like to focus on automatic techniques for visual analysis of human
communication and on the applications that are built on top of it. We
welcome contributions that present robust techniques for the analysis of
gestures and facial expressions in natural conversational environments
to model social behavior in everyday life and reason about them. We also
strongly encourage the participation of colleagues from behavioral
sciences: studies of nonverbal behavior and social interaction provide
highly valuable information, concepts, and frameworks to guide automatic
analysis, while efforts in automatic analysis of social behavior provide
new tools, data, and insights to behavioral scientists interested in
nonverbal behavior and social interaction.
We invite contributions that address the following (non-exhaustive) list
of topics:
Social behavior analysis
* Analysis and recognition of visual social cues and others:
o Visual nonverbal cues (body postures, hand gestures, head
gestures, actions …)
o Multimodal affect recognition
o Nonverbal cues from other sensors
* Multimodal computational models for the analysis, estimation, and
prediction of social behavior aspects and dimensions (interest level,
dominance, rapport, deception…) and of individual properties affecting
it (e.g., personality traits, preferences…)
* Analysis of conversational dynamics
* Multimodal data corpora for social behavior analysis
Systems and devices for capturing social behavior
* Smart camera/microphone systems
* Novel sensor technologies
* Wearable devices
* Cell phones
Socially aware systems and applications
* Computers and robots in the human interaction loop
* Individual and group self-awareness
* Educational applications
* Workplace applications
* Healthcare applications
* Game applications
* Art & creative applications

Call for papers: Self-* Search (New Frontiers Track)
at GECCO, July 12-16, Dublin, Ireland
Visit http://www.sigevo.org/gecco-2011/
—————————————————–
Search and optimization problems are everywhere, and search algorithms
are getting increasingly powerful. However, they are also getting
increasingly complex, and only autonomous self-managed systems that
provide high-level abstractions can turn search algorithms into widely
used methodologies. Such systems should be able to configure themselves
on the fly, automatically adapting to the changing problem conditions,
based on general goals provided by their users.
The aim of the Self-* Search track at GECCO 2011 is to bring together
all researchers interested in software systems able to automatically
tune, configure, or even generate and design optimization algorithms
and search heuristics.
The Self-* Search track is a brand new track in 2011, selected among
the competing entries to the “New Frontiers Track” for its novelty and
potential. It is an exciting opportunity to explore emerging new
research directions, and to confront ideas originating from the
different fields of Computer Science concerned with adaptive search and
optimization, from Artificial Intelligence to Operational Research and
Mathematical Programming.
We invite all papers related to Self-* Search, in particular (but not
limited to) those in the following subject areas: hyper-heuristics,
adaptive and self-adaptive parameter control, adaptive operator
selection, automated construction of search heuristics, systems to
build systems, computer-aided algorithm design, multi-level search,
experimental analysis of algorithms, automatic algorithm configuration,
adaptive multimeme algorithms, software self-assembly, reactive search,
intelligent optimization, algorithm selection and portfolios, and all
applications of self-* techniques to multi-objective, dynamic, and
complex real-world problems.
Self-* Search related papers were scattered across several GECCO tracks
in previous editions. We have this year a unique opportunity to both
gather and unify these threads into a single track, and open up the
scope for new and ambitious research directions in automated
heuristic design, and autonomic computing in general. Our hope is
that your numerous submissions will demonstrate the importance of
this line of research, and that this track will continue to flourish
with your support and enthusiasm.
