Special Issue on Recommender System Benchmarking

 http://tist.acm.org/CFPs/TIST-SI-RSB.html

Overview
------------
Recommender systems add value to vast content resources by matching users with items of interest. In recent years, immense progress has been made in recommendation techniques. The evaluation of these systems is still based on traditional information retrieval and statistics metrics, e.g. precision, recall, RMSE often not taking the use-case and situation of the system into consideration.

However, the rapid evolution of recommender systems in both their goals and their application domains foster the need for new evaluation methodologies and environments.

This special issue serves as a venue for work on novel, recommendation-centric benchmarking approaches taking the users utility, the business values and the technical constraints into consideration.

New evaluation approaches should evaluate both functional and non-functional requirements. Functional requirements go beyond traditional relevance metrics and focus on user-centered utility metrics, such as novelty, diversity and serendipity.

Non-functional requirements focus on performance (e.g., scalability of both model building and on-line recommendation phases) and reliability (e.g., consistency of recommendations with time, robustness to incomplete, erroneous or malicious input data).

Topics of Interests
------------------------
We invite the submission of high-quality manuscripts reporting relevant research in the area of benchmarking and evaluation of recommendation systems. The special issue welcomes submissions presenting technical, experimental, methodological and/or applicative contributions in this scope, addressing -though not limited to- the following topics:

• New metrics and methods for the quality estimation of recommender systems
• Mapping metrics to business goals and values
• Novel frameworks for the user-centric evaluation of recommender systems
• Validation of off-line methods with online studies
• Comparison of evaluation metrics and methods
• Comparison of recommender algorithms across multiple systems and domains
• Measuring technical constraints vs. accuracy
• Robustness of recommender systems to missing, erroneous or malicious data
• Evaluation methods in new application scenarios (cross domain, live/stream recommendation)
• New datasets for the evaluation of recommender systems
• Benchmarking frameworks
• Multiple-objective benchmarking
• Real benchmarking experiences (from benchmarking event organizers)

Submissions
-----------------
Manuscripts shall be sent through the ACM TIST electronic submission system at http://mc.manuscriptcentral.com/tist (please select "Special Issue: Recommender System Benchmarking" as the manuscript type). Submissions shall adhere to the ACM TIST instructions and guidelines for authors available at the journal website: http://tist.acm.org.

10 PhD positions in new Data Science Centre at Edinburgh, UK

 10 PhD places in new Centre for Doctoral Training in Data Science

 Web site: http://datascience.inf.ed.ac.uk/

 Application deadline: 27 January 2014 (first round)

The Edinburgh Centre for Doctoral Training (CDT) in Data Science is
now inviting applications for 10 fully-funded PhD studentships, to
start in September 2014. Students with a strong background in computer
science, mathematics, physics, or engineering are particularly
encouraged to apply.

The CDT focuses on the computational principles, methods, and systems
for extracting knowledge from data. Large data sets are now generated
by almost every activity in science, society, and commerce - ranging
from molecular biology to social media, from sustainable energy to
health care. Data science asks: How can we efficiently find patterns
in these vast streams of data?  Many research areas have tackled parts
of this problem: machine learning focuses on finding patterns and
making predictions from data; ideas from algorithms and databases are
required to build systems that scale to big data streams; and separate
research areas have grown around different types of unstructured data
such as text, images, sensor data, video, and speech.  Recently, these
distinct disciplines have begun to converge into a single field called
data science.

The CDT is a 4-year programme: the first year provides Masters level
training in the core areas of data science, along with a significant
project. In years 2-4 students will carry out PhD research in Data
Science, guided by PhD supervisors from within the centre. The CDT is
funded by EPSRC and the University of Edinburgh.

Edinburgh has a large, world-class research community in data science
to support the work of the CDT student cohort.  The city of Edinburgh
has often been voted the 'best place to live in Britain', and has many
exciting cultural and student activities.

Because of constraints from funding agencies, there are different
rules for funding depending on your fee status:
   * UK and EU students: Full funding (fees and stipend) is available.
   * Non-EU students: Funding is significantly more competitive;  see
     http://datascience.inf.ed.ac.uk/apply/information-for-non-eu-students/
     for details.

See http://datascience.inf.ed.ac.uk/apply/ for further information and
application forms. Enquiries via datascience@inf.ed.ac.uk .

There are two deadlines for applications:

 * First round deadline for full consideration. Apply by 27 January
   2014. (Any non-EU candidates must apply by this date, as well as
   following the specific instructions for non-EU residents.)

 * Second round: Any remaining scholarships will be awarded in a
   second round of applications. The deadline for the second round is
   31 March 2014.

DEOS 2014: Fourth Workshop on Data Extraction and Object Search (April 7) in conjunction with WWW'14, April 7-11, Seoul, South Korea.

http://diadem.cs.ox.ac.uk/deos14/

Important Dates
-----------------------------------------------------------
Paper submission: *Jan 7, 2014 (23:59 Hawaii Standard Time)* Paper notification: *Feb 4, 2014* Paper camera-ready copy: *Feb 12, 2014* (hard deadline) Workshop date: April 7, 2014
-----------------------------------------------------------

Description
-----------------------------------------------------------
The Fourth International Workshop on “Data Extraction and Object Search” (DEOS 2014) will take place as a satellite event of WWW 2014 in Seoul, South Korea, on April 7th, 2014.

Web data extraction is witnessing a renaissance. In an increasing number of applications such as price intelligence or predictive analytics, the value of data-driven approaches has been conclusively proven. However, the necessary data is often available only as HTML, e.g., in form of online shops of competitors that can serve as sources for pricing and offer data. DEOS is a regular forum for researchers and practitioners in data extraction and object search, to present and discuss ongoing work on data extraction and object search for products, events, reviews, and other types of structured data on the web.

This is the fourth installation of DEOS, the first held in Como in 2010, the second in Vienna in 2011, the third in Oxford in 2013. The workshop is supported by the ERC DIADEM grant (http://diadem.cs.ox.ac.uk/) and the Oxford Martin school (http://www.oxfordmartin.ox.ac.uk/). There is a small amount of travel support available from the sponsors.


Topics
-----------------------------------------------------------
This installment of the workshop places a particular emphasis on benchmarking and effective evaluation measures for data extraction.

The topics of interest include (but are not limited to):
* Large-scale data extraction approaches capable of dealing with a large number of websites without per-site supervision.
* Object identification and extraction approaches in domains such as products, events, reviews, forum posts, ...
* Reducing and simplifying supervision in wrapper induction and the use of crowdsourcing.
* Automatic crawling and exploration of web interfaces with a particular focus on highly-visual, scripted web applications.
* Information extraction meets data extraction including approaches that integrate information extraction, e.g., from product titles, with data extraction for mutual verification of the data.
* Automated data extraction approaches that identify wrappers fully automatically at high accuracy.
* Integration and cleaning of extracted web data for object search including approaches or tools for deduplication (intra- and inter-site) and for reconciliation of conflicting attribute values.
* Object search approaches and systems that provide a search interface to data extracted from the web.
* Evaluation, benchmarking, and replicability in web data extraction and object search.


Submissions
-----------------------------------------------------------

DEOS’14 welcomes the submission of theoretical, experimental, methodological as well as application papers. Benchmark papers are particularly encouraged and demonstration papers are also welcome.

Submitted papers should be 8 pages (4 pages for demo proposals, work in progress, or vision papers) maximum in length, including figures and references. The paper must be formatted as PDF according to style guidelines of ACM SIG Proceedings Template available here: http://www.acm.org/sigs/publications/proceedings-templates.

All papers should be submitted online on the workshop submission website: https://www.easychair.org/conferences/?conf=deos14.

Information Systems Engineering in Times of Crisis
http://delab.csd.auth.gr/caise2014/

Real-time information systems and overly complex financial products have been blamed as causes of recent financial crises. The IS Engineering community is treating such phenomena as challenges, to be addressed through research and improved practices. In particular, our community has begun to address the role of information systems in predicting, preventing, and reacting to crises of many different kinds: data-centric financial and fiscal dependency analysis of the globalized financial systems, resilience of critical infrastructures by information management, reaction to natural disasters such as fires, floods, earthquakes, etc. Due to the very nature of crises as unexpected events with broad and vast impact, IS Engineering challenges traditional wisdom and methodologies, as well as interactions between research and practice including stakeholders such as crisis victims.
CAiSE '14 will, as always, act as a forum of discussion that brings together researchers and practitioners in the field of IS Engineering. It will be the place to share mature research, ground-breaking ideas, and experience reports in our discipline.
CAiSE welcomes all submissions that fall in the domain of information systems engineering. This year, the conference extends a special welcome to papers that address the role of IS engineering in crisis situations.

Author Guidelines
Types of contributions. We invite four types of original and scientific papers:
Formal and/or technical papers describe original solutions (theoretical, methodological or conceptual) in the field of IS engineering. A technical paper should clearly describe the situation or problem tackled, the relevant state of the art, the position or solution suggested and the potential - or, even better, the evaluated - benefits of the contribution.
Empirical evaluation papers evaluate existing problem situations or validate proposed solutions with scientific means, i.e. by empirical studies, experiments, case studies, simulations, formal analyses, mathematical proofs, etc. Scientific reflection on problems and practices in industry also falls into this category. The topic of the evaluation presented in the paper as well as its causal or logical properties must be clearly stated. The research method must be sound and appropriate.
Experience papers present problems or challenges encountered in practice, relate success and failure stories, or report on industrial practice. The focus is on 'what' and on lessons learned, not on an in-depth analysis of 'why'. The practice must be clearly described and its context must be given. Readers should be able to draw conclusions for their own practice.
Exploratory Papers can describe completely new research positions or approaches, in order to face to a generic situation arising because of new ICT tools or new kinds of activities or new IS challenges. They must describe precisely the situation and demonstrate how current methods, tools, ways of reasoning, or meta-models are inadequate. They must rigorously present their approach and demonstrate its pertinence and correctness to addressing the identified situation.
Submission Conditions. Papers should be submitted in PDF format. The results described must be unpublished and must not be under review elsewhere. Submissions must conform to Springer's LNCS format and should not exceed 15 pages, including all text, figures, references and appendices. Submissions not conforming to the LNCS format, exceeding 15 pages, or being obviously out of the scope of the conference, will be rejected without review. Information about the Springer LNCS format can be found at http://www.springer.de/comp/lncs/authors.html. Three to five keywords characterizing the paper should be indicated at the end of the abstract. The type of paper (technical/empirical evaluation/experience/exploratory paper) should be indicated in the submission.
Publication. Accepted papers will be presented at CAiSE'14 and published in the conference proceedings, which is published in the Springer Lecture Notes in Computer Science (LNCS). Authors elected best papers from the conference will be invited to submit an expanded version for publication in the journal, Information Systems.

Venue
Thessaloniki is the second largest city of Greece, with a population of 1.000.000 people. Apart from its landmark, the White Tower, the city boasts important historical sites, museums and cultural activities. It is also known as a cosmopolitan and commercial center, with exceptional nightlife in its famous Ladadika quarter. The music scene in the city is vibrant and diverse and includes nightclubs, dance halls, discos, cafes and music bars, jazz clubs and more, along with a wealth of live performances, both musical and theatrical. In addition to important Byzantine and Archaeological museums within the city, travellers can visit the Archaeological site of Vergina (the capital of ancient Macedonia). This is the venue of Phillip's tomb (the father of Alexander the Great), a site full of remarkable treasures of art and culture. Also within a short distance (45 minutes by car) one can visit mount Olympus (the mountain of the ancient Gods) where "Dion" the holy city of ancient Macedonia is located. For these and many other reasons, Thessaloniki is the cultural capital of northern Greece! CAISE'2014 will be hosted at the MET Hotel (http://www.themethotel.gr), located very close to the historic center of Thessaloniki, 17 km from "Macedonia" airport. A block of rooms has been reserved for the conference registrants.

The Web and social media are growing both in size and complexity, as well as
playing an increasing role in our lives. Finding relevant, timely and
trustworthy content in a sea of seemingly irrelevant chatter remains a
challenging research issue. On one hand, this workshop deals with the more
blatant and malicious attempts that deteriorate web quality such as spam,
plagiarism, or various forms of abuse and ways to prevent them or neutralize
their impact on users' experience. On the other hand, it will also provide a
venue for exchanging ideas on quantifying and modeling issues of content
quality, credibility and author reputation.

The objective of the workshop is to provide the research communities working
on web quality topics with a survey of current problems and potential solutions.
It presents an opportunity for close interaction between researchers and
practitioners who may be focused on isolated sub-areas. We also want to
gather crucial feedback for the academic community from participants
representing major industry players on how web content quality research can
contribute to practice.

TOPICS

Particular areas of interest include, but are not limited to:

Assessing the credibility of content and people on the web and social media
* Measuring quality of web content
* Uncovering distorted and biased content
* Modeling author identity, trust, and reputation
* Role of groups and communities
* Multimedia content credibility

Fighting spam, abuse, and plagiarism on the Web and social media
* Reducing web spam
* Reducing abuses of electronic messaging systems
* Detecting abuses in internet advertising
* Uncovering plagiarism and multiple-identity issues

WWW 2014 Workshop - The 4th Making Sense of Microposts Workshop (#Microposts2014)

The 4th Making Sense of Microposts Workshop (#Microposts2014) at WWW 2014

http://www.scc.lancs.ac.uk/microposts2014

7 April 2014, Seoul, Republic of Korea


THEME
-------------------

Making Sense of Microposts: Big things come in small packages

Microposts, such as Twitter status updates, Instagram likes and photos and Foursquare checkins, form a notable part of published web content. Smart phones, after overtaking sales of personal computers in 2012, now play a significant role in enabling ubiquitous communication, and have contributed to the steep increase in publication of Microposts, via native mobile apps and mobile-specific web sites. The increase in Micropost publication is evident across Twitter, where 500 million posts are now published every day, up from 175 million in 2012. Facebook sees 30 billion pieces of content shared on it every month. Such statistics reflect the growing production and consumption of data by users and the widespread sharing of information through social networks. The utility of Microposts is such that we are now providing up-to-date information about a range of topics formed in disparate contexts, providing information about emerging events, online presence, emergency response and c!
rowd movement. Being able to make sense of Microposts therefore impacts on the ability to act upon information quickly and effectively, and aids the understanding of evolving user behaviour, events and public perception and opinion about their worlds.

The central objective of the #Microposts workshop is to bring together researchers from multiple disciplines to discuss and debate current efforts toward analysing and understanding Microposts. We define a Micropost as information published on the Web that is small in size (e.g. a Tweet, Facebook share, Instagram like) and that requires minimal effort to publish. Although individual Microposts are small, collectively they provide a rich source of current information about a range of topics across all walks of life. Gleaning information from such content effectively requires a degree of understanding of what is being discussed and, with very large amounts, semi- to fully automated analytical and extraction approaches.
The workshop aims to provide a forum to enable discussion and hence, improve understanding of social and cultural phenomena that influence the publication and reuse of Microposts; and to discuss applications of Micropost data in a variety of contexts, including emergency response, crowd and event tracking, public opinion and sentiment analysis. Enabling the understanding and application of Micropost content requires analytical techniques and tools that function at scale and that can handle the high rate at which Microposts are published. The workshop invites submissions that deal with publication rate and scale, and approaches that facilitate understanding of Microposts through their semantics and where available, contextual information.

Microposts are both a technical and a social phenomenon, and the nature of the challenge related to their treatment is therefore multi-disciplinary. We continue to promote a multidisciplinary workshop, as achieved in the past three in the series, by also encouraging social scientists and other non-Computer Science researchers to submit work that looks at the theories behind Micropost usage and communication through this medium. The workshop also encourages demonstration of practical application of the results of analysis of Micropost data, both within the research community and in everyday, real-world scenarios. We encourage submissions using this and last year’s challenge data for contributions to the main track.



TOPICS OF INTEREST
-------------------

The workshop will focus on topics including, but not exclusive to, the three areas below:

Data mining from Microposts
-Emergent semantics
-Opinion mining, sentiment and sentic analysis -Network analysis and community detection -Influence detection and social contagion modelling -Prediction approaches -Linking Microposts into the Web of Data -Semantic entity disambiguation

Social & Web Science Studies
-Collective awareness
-Education & citizen empowerment, data journalism -Civil action, media & politics -Political and polemical aspects of Microposts -Ethics, legal and privacy issues -Psychological profiles and psychological aspects of Micropost-based interactions -Cultural and regional differences in access and use

Applications
-Collective intelligence, including user profiling, personalisation & recommendation -Business analytics & market intelligence -Event & topic detection and tendency tracking -Microposts as second screen to TV -Geo-localized, Micropost-based services -Public consensus & citizen participation -Security, emergency response & health -Linking social and physical signals, in, e.g., crowd tracking




ENTITY EXTRACTION & DISAMBIGUATION CHALLENGE
----------------------------

#Microposts2014 will host an 'Entity Extraction & Disambiguation Challenge', where participants must label Microposts in a given dataset with the entities referenced and their semantic web URIs. Existing entity extraction and disambiguation tools are intended for use over news corpora and similar document-based corpora with relatively long length. The aim of the challenge is to foster research into novel, more accurate entity extraction and disambiguation for (much shorter) Micropost data. Detailed information on how to enter the challenge will be provided in a separate call for challenge submissions as well as on the workshop website.



WORKSHOP STRUCTURE
-------------------

A keynote address from an invited speaker will open the day. This will be followed by paper presentations. We will hold a poster and demo session to trigger further, in-depth interaction between workshop participants. The last set of presentations will be brief overviews of selected submissions to the Entity Extraction & Disambiguation Challenge The workshop will close with the presentation of awards for the best paper and the highest ranking challenge submission.


SUBMISSIONS
------------

* Full papers: 8 pages ACM SIG format
* Short and position papers: 4 pages ACM SIG format
* Demos & Posters: 2 pages ACM SIG format
* Challenge extended abstracts: 5 pages Springer LNCS format

Main track submissions should be prepared according to the ACM SIG Proceedings Template (see http://www.acm.org/sigs/publications/proceedings-templates), and should include author names and affiliations, and 3-5 keywords.
Further detail for challenge submissions will be provided in a separate call.

Submission is via the EasyChair Conference System, at: https://www.easychair.org/conferences/?conf=microposts2014. Where a submission includes additional material submission this should be made as a single, unencrypted zip file that includes a plain text file listing its contents.
