The 6th Annual Workshop on Simplifying Complex Networks for Practitioners
Organizers: Aziz Mohaisen, Hyoungshick Kim, Yong Li, Pan Hui and Nishanth Sastry

Simplex aims at triggering different computer science communities (e.g. communication networks, distributed systems) to propose research areas and topics that should be tackled from the network science perspective. We also seek contributions from network science that are relevant to solve practical computer science problems. Two types of contributions are foreseen from prospective authors. The first type would consist of use-cases of theoretical tools and methods to solve practical problems, while the second type of contributions would come from practitioners that have identified a problem that may be solved by tools from network sciences.

WebQuality2014: The 4th Joint WICOW/AIRWeb Workshop on Web Quality
Organizers: Adam Jatowt, Carlos Castillo, James Caverlee and Katsumi Tanaka

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. Read More

DEOS’14: Data Extraction and Object Search ‘14
Organizers: Tim Furche, Giorgio Orsi, Paolo Merialdo, and Valter Crescenzi

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 year’s DEOS focuses on the challenges in scaling data extraction to the variety and volume of different data sources available only as HTML on the web. Read More

SOCM2014: The Theory and Practice of Social Machines
Organizers: Nigel Shadbolt, James Hendler, Noshir Contractor and Elena Simperl

Continuing from last year’s Theory and Practice of Social Machines workshop at WWW2013, the second edition of the SOCM workshop will look deeply at social machines that have, or may yet soon have, a profound impact on the lives of individuals, businesses, governments, and the society as a whole in significant ways. Our goal is to study both extant and yet unrealized social machines, to identify factors that govern the growth or impede these systems to develop, and to identify unmet potential needs (both human and technical) for the kinds of loosely-coordinated distributed social systems the Web enables. The workshop will discuss methods to analyze and explore social machines, as essential mechanisms for deriving the guidelines and best practices that will inform the design the next generation of these systems.

Workshop on Web-based Education Technologies (WebET 2014)
Organizers: Irwin King and Bebo White
The goal of this workshop is to bring together subject matter experts and practitioners to discuss the current status of Web-­Based Education (WBE), future trends in the field, and the challenges to be addressed in order to assure the ongoing success of WBE systems. The convergence (“a perfect storm”) of new technologies supporting search, social media, semantics, data mining (Big Data), and others along with current interest to distributed educational pedagogies such as connectivism, behaviorism, and “the flipped classroom” promises to dramatically change Web­-Based education in the near future. The interest in Massive Open Online Courses (MOOCs) has been described as “a tsunami in education” and has re­kindled valuable discussions re: the role of WBE. Read More
Vertical Search Relevance Workshop
Organizers: Hongbo Deng, Jiang Bian, Yi Chang and Neel Sundaresan
One of the emerging trends of information needs in search engine is using vertical search intent. For example, a user may want to find a restaurant near her current location; another user may want to follow the recent development of a breaking event such as the earthquake in Japan. Recent studies reveal that vertical search engines start attracting more and more attention. Thus, designing effective ranking functions for vertical search has become practically important to improve users’ search experience. However, in many verticals, the meaning of relevance is domain-specific and usually consists of multiple well-defined aspects. Thus, we have identified a list of challenging research issues in the field of relevance for vertical search, which mainly fall into two categories, including (1) how to learn an effective ranking model considering multi-facets relevance; (2) how to build effective business model in the context of specific vertical search systems. This workshop is dedicated to presentations and discussions on relevance for vertical search. The workshop will bring together researchers from IR, ML, NLP, and other areas of computer and information science who are working on or interested in this area, and provide a forum for them to identify the issues and the challenges, to share their latest research results, to express a diverse range of opinions about this topic, and to discuss future directions.

#Microposts2014 – The 4th Making Sense of Microposts Workshop
Organizers: Matthew Rowe, Milan Stankovic and Aba-Sah Dadzie
Microposts, such as Twitter status updates, Instagram likes and photos and Foursquare checkins, form a notable part of published web content. 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 crowd 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. 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.

4th Temporal Web Analytics Workshop (TempWeb)
Organizers: Ricardo Baeza-Yates, Julien Masanes and Marc Spaniol
TempWeb focuses on investigating infrastructures, scalable methods, and innovative software for aggregating, querying, and analyzing heterogeneous data at Internet scale. Particular emphasis is given to temporal data analysis along the time dimension for Web data that has been collected over extended time periods. A major challenge in this regard is the sheer size of the data it exposes and the ability to make sense of it in a useful and meaningful manner for its users. Web scale data analytics therefore needs to develop infrastructures and extended analytical tools to make sense of the mass of information that the historic and current web represent. Read More

2nd International Web Observatory Workshop (WOW2014)
Organizers: Kevin Page, David De Roure and Wolfgang Nejdl
The Web operates at a very large scale and is dominated by emergent phenomena with radical innovations coming from and driven by its users and in time scales that are faster than those exhibited by earlier computer-based systems. We are just beginning to understand how to conduct scientific research on the huge and constantly changing socio-technical system formed by the web and all the people and agents that use it. There are significant challenges in deploying methodologies, datasets, and analytic and visualisation tools, which are fundamental elements of Web Observatories. Scientific method begins with instrumentation and measurement to describe and characterize what is actually happening. Only then can we begin to develop theories and abstractions that enable better design of future evolutions of the systems and quantitative predictions of their behaviour. Read More

5th International Workshop on Social Recommender Systems (SRS2014)
Organizers: Jian Wang, Ido Guy and Li Chen
Social Recommender Systems (SRSs) aim to alleviate information overload over social media users by presenting the most attractive and relevant content, often using personalization techniques adapted for the specific user. Social media and recommender systems can mutually benefit from one another. On the one hand, social media introduces new types of public data and metadata, such as tags, comments, votes, and explicit people relationships, which can be utilized to enhance recommendations. On the other hand, recommender systems can significantly affect the success of social media, ensuring each user is presented with the most attractive and relevant content, on a personal basis.Read More
