• Article: Leveraging semantic similarity for folksonomy-based recommendation

  Daniela Godoy, Gustavo Rodriguez, Franco Scavuzzo
  [show abstract] [hide abstract]
  ABSTRACT: For recommending interesting resources, such as Web pages or pictures available in social tagging systems, assessing their similarity with user profiles is crucial. Here, we analyze the role of semantic similarity to calculate the resemblance between user profiles and published resources in folksonomies. Experiments carried out with data from two social sites showed that associating semantics to tags results in more accurate similarities among elements in tagging systems and, consequently, enhances recommendations.

• Article: MobileWorks: Designing for Quality in a Managed Crowdsourcing Architecture

  Anand Kulkarni, Philipp Gutheim, Prayag Narula, David Rolnitzky, Tapan Parikh, Björn Hartmann
  [show abstract] [hide abstract]
  ABSTRACT: Online labor marketplaces offer the potential to automate tasks too difficult for computers, but don't always provide accurate results. MobileWorks is a crowd platform that departs from the marketplace model to provide robust, high-accuracy results using three new techniques. A dynamic work-routing system identifies expertise in the crowd and ensures that posted work completes within a bounded time with fair wages. A peer-management system helps prevent wrong answers. Last, social interaction techniques let best workers manage and teach other crowd members. This process allows the crowd to collaboratively learn how to solve new tasks.

• Article: Toward an Open Cloud Standard

  Andrew Edmonds, Thijs Metsch, Alexander Papaspyrou, Alexis Richardson
  [show abstract] [hide abstract]
  ABSTRACT: Today’s cloud ecosystem features a number of differing and increasingly diverging interfaces for management. In fact, a number of bridging efforts, such as the well-known libcloud or DeltaCloud projects, have been started to ameliorate the resulting vendor lock-in for the customers. With the current pace of growth in the number of providers, this approach shows its main drawback: the maintenance of adapter implementations. The Open Cloud Computing Interface (OCCI) brings this effort to the next level by taking a different approach: building on the fundamentals of modern web-based services, it defines a standardised interface towards cloud environments while enabling service providers to differentiate at the same time. In this article, we review the need for standards in the cloud arena, discuss the technicalities of OCCI, show its impact, and review its merits with respect to the currently popular proxy approach taken by competing efforts.

• Article: CAPTCHA Design: Color, Usability, and Security

  A.S. El Ahmad, J. Yan, Wai-Yin Ng
  [show abstract] [hide abstract]
  ABSTRACT: Most user interfaces use color, which can greatly enhance their design. Because the use of color is typically a usability issue, it rarely causes security failures. However, using color when designing CAPTCHAs, a standard security technology that many commercial websites apply widely, can have an impact on usability and interesting but critical implications for security. Here, the authors examine some CAPTCHAs to determine whether their use of color negatively affects their usability, security, or both.

• Article: Querying Heterogeneous Datasets on the Linked Data Web: Challenges, Approaches, and Trends

  A. Freitas, E. Curry, J.G. Oliveira, S. O'Riain
  [show abstract] [hide abstract]
  ABSTRACT: The growing number of datasets published on the Web as linked data brings both opportunities for high data availability and challenges inherent to querying data in a semantically heterogeneous and distributed environment. Approaches used for querying siloed databases fail at Web-scale because users don't have an a priori understanding of all the available datasets. This article investigates the main challenges in constructing a query and search solution for linked data and analyzes existing approaches and trends.

• Article: Multiterm Keyword Search in NoSQL Systems

  C. von der Weth, A. Datta
  [show abstract] [hide abstract]
  ABSTRACT: Distributed NoSQL systems aim to provide high availability for large volumes of data but lack the inherent support of complex queries often required by overlying applications. Common solutions based on inverted lists for single terms perform poorly in large-scale distributed settings. The authors thus propose a multiterm indexing technique that can store the inverted lists of combinations of terms. A query-driven mechanism adaptively stores popular term combinations derived from the recent query history. Experiments show that this approach reduces the overall bandwidth consumption by half, significantly improving the NoSQL system's capacity and response time with only marginal overhead in terms of additional, but cheaper, required (storage) resources.

• Article: PNUTS in Flight: Web-Scale Data Serving at Yahoo

  A. Silberstein, Jianjun Chen, D. Lomax, B. McMillan, M. Mortazavi, P.P.S. Narayan, R. Ramakrishnan, R. Sears
  [show abstract] [hide abstract]
  ABSTRACT: Data management for stateful Web applications is extremely challenging. Applications must scale as they grow in popularity, serve their content with low latency on a global scale, and be highly available, even in the face of hardware failures. This need has generated a new class of Internet-scale data management systems. Yahoo has more than 100 user-facing applications and numerous internal platforms. To meet its data management needs, it built the PNUTS system. Here, the authors review PNUTS' growing adoption, point to specific applications, and detail several of PNUTS' features.

• Article: Is the Browser the Side for Templating?

  F.J. Garcia-Izquierdo, R. Izquierdo
  [show abstract] [hide abstract]
  ABSTRACT: Browser-side templating (BST) is a valid alternative for Web development, even when it comes to building accessible applications. BST processes templates in the browser using a JavaScript-coded engine, providing significant performance improvements and making model-view separation a reality. However, it also has significant drawbacks. BST's dependence on JavaScript affects its accessibility and hides the delivered pages' content from search engines, hampering Web visibility. The authors confront this dilemma and propose a technique that lets BST be accessible and semantically crawlable, while preserving its advantages.

• Article: HorNet: Microblogging for a Contributory Social Network

  Daniel Lázaro Iglesias, Joan-Manuel Marquès, Guillem Cabrera, Helena Rifà-Pous, Albert Montané
  [show abstract] [hide abstract]
  ABSTRACT: Online social networks play an important role in everyday life for many people. However, only a few specialized companies offer services and resources that support social networks. This could expose users to undesired publicity and make them vulnerable to information control and censorship. HorNet is a decentralized alternative implementation of a microblogging social network that depends solely on user-provided computational resources. With the service load distributed across all users, each one must contribute only a small amount of resources, and the social network can remain free and under members' control.

• Article: Mobile Querying of Online Semantic Web Data for Context-Aware Applications

  W. Van Woensel, S. Casteleyn, E. Paret, O. De Troyer
  [show abstract] [hide abstract]
  ABSTRACT: Mobile devices are increasingly multifunctional and personal, providing mobile applications with the necessary user information to achieve personalization. At the same time, detection technologies let such devices find nearby physical entities and thus map the user's environment. By exploiting existing online Semantic Web sources about these detected entities, mobile applications can further improve personalization. SCOUT is a mobile application framework that supports linking physical entities to online semantic data sources. It provides applications with an integrated, query-able view on these sources and the user's environment. The authors developed a tailored data management approach to efficiently access these distributed online semantic sources.
