TL;DR: This study presents a comparative analysis of the international landscape of Prekindergarten through 12th grade engineering education and provides guidelines and samples of state-of-the art resources in each language for teachers interested in introducing their students to engineering as a reliable starting point towards PreK-12 engineering information gathering.
Abstract: The newly formed discipline of engineering education is addressing the need to (a) enhance STEM education for precollege students and (b) identify optimum ways to introduce engineering content starting, perhaps, from the early ages. Introducing engineering at the Prekindergarten through 12th grade (PreK-12) education level requires significant changes in teacher preparation and support. It highlights the need for developing developmentally appropriate content knowledge and pedagogical methods, thus revealing the challenges of preparing teachers to incorporate this type of knowledge base into their practice. Although professional development offered by universities, school districts, and other educational entities provides the primary source of formal learning tools for teachers, an increasing number of teachers also utilize other informal web-based resources regularly. This paper examines available PreK-12 engineering web resources offered by entities formally related to education in seven different languages, namely Arabic, Chinese (Mandarin), English, French, Greek, Korean, and Spanish. Findings showed how different educational systems designated different attention to the entry level ages when introducing engineering content. Differences in the terminology used to identify STEM resources for introducing these topics also became apparent. Similarities suggest that a large number of resources available on the web were originating in all researched languages. However, the developmental appropriateness and content validity of many of these resources remained questionable in many cases. In general, there was a plethora of isolated activities and lesson plans but significantly fewer complete engineering curricula available to teachers on the web. This study presents a comparative analysis of the international landscape of PreK-12 engineering education and provides guidelines and samples of state-of-the art resources in each language for teachers interested in introducing their students to engineering as a reliable starting point towards PreK-12 engineering information gathering.

TL;DR: This paper builds a new cache analysis model and study the upper bound of how high percentage of resources could potentially be cached and how effective the caching works in practice, and identifies two major problems -- Redundant Transfer and Miscached Resource, which lead to unsatisfactory cache performance.
Abstract: The Web browser is a killer app on mobile devices such as smartphones. However, the user experience of mobile Web browsing is undesirable because of the slow resource loading. To improve the performance of Web resource loading, caching has been adopted as a key mechanism. However, the existing passive measurement studies cannot comprehensively characterize the performance of mobile Web caching. For example, most of these studies mainly focus on client-side implementations but not server-side configurations, suffer from biased user behaviors, and fail to study "miscached" resources. To address these issues, in this paper, we present a proactive approach for a comprehensive measurement study on mobile Web cache performance. The key idea of our approach is to proactively crawl resources from hundreds of websites periodically with a fine-grained time interval. Thus, we are able to uncover the resource update history and cache configurations at the server side, and analyze the cache performance in various time granularities. Based on our collected data, we build a new cache analysis model and study the upper bound of how high percentage of resources could potentially be cached and how effective the caching works in practice. We report detailed analysis results of different websites and various types of Web resources, and identify the problems caused by unsatisfactory cache performance. In particular, we identify two major problems -- Redundant Transfer and Miscached Resource, which lead to unsatisfactory cache performance. We investigate three main root causes: Same Content, Heuristic Expiration, and Conservative Expiration Time, and discuss what mobile Web developers can do to mitigate those problems.

TL;DR: The methods and tools used for keeping the personal data away from being tracked are described and several tools that were used for research purposes are presented – their main goal is to discover how and by which entity the users are being tracked on their desktop computers or smartphones, provide this information to the users, and visualize it in an accessible and easy to follow way.
Abstract: This articles surveys the existing literature on the methods currently used by web services to track the user online as well as their purposes, implications, and possible user’s defenses.
A significant majority of reviewed articles and web resources are from years 2012–2014. Privacy seems to be the Achilles’ heel of today’s web. Web services make continuous efforts to obtain as much information as they can about the things we search, the sites we visit, the people with who we contact, and the products we buy. Tracking is usually performed for commercial purposes. We present 5 main groups of methods used for user tracking, which are based on sessions, client
storage, client cache, fingerprinting, or yet other approaches.
A special focus is placed on mechanisms that use web caches, operational caches, and fingerprinting, as they are usually very rich in terms of using various creative methodologies. We also show how the users can be identified on the web and associated with their real names, e-mail addresses, phone numbers, or even street addresses. We show why tracking is being used and its possible implications for the users. For example, we describe recent cases of price discrimination, assessing financial credibility, determining insurance coverage, government surveillance, and identity theft. For each of the tracking methods, we present possible defenses. Some of them are specific to a particular tracking approach, while others are more universal (block more than one threat) and they are discussed separately. Apart from describing the methods and tools used for keeping the personal data away from being tracked, we also present several tools that were used for research purposes – their main goal is to discover how and by which entity the users are being tracked on their desktop computers or smartphones, provide this information to the users, and visualize it in an accessible and easy to follow way.
Finally, we present the currently proposed future approaches to
track the user and show that they can potentially pose significant
threats to the users’ privacy.

TL;DR: Experimenting with Linked Data using existing bibliographic metadata using existing library metadata holds the potential to empower libraries to harness the reach of commercial search engines to continuously discover, navigate, and obtain new domain specific knowledge resources on the basis of their verified metadata.
Abstract: By way of a case study this paper illustrates and evaluates the Bibliographic Framework (or BIBFRAME) as means for harvesting and sharing bibliographic metadata over the Web for libraries. BIBFRAME is an emerging framework developed by the Library of Congress for bibliographic description based on Linked Data. Much like Semantic Web, the goal of Linked Data is to make Web “data aware” and transform the existing Web of documents into a Web of data. Linked Data leverages the existing Web infrastructure and allows linking and sharing of structured data for human and machine consumption. The BIBFRAME model attempts to contextualize the Linked Data technology for libraries. Library applications and systems contain high-quality structured metadata but this data is generally static in its presentation and seldom integrated with other internal metadata sources or linked to external Web resources. With BIBFRAME existing disparate library metadata sources such as catalogs and digital collections can be harvested and integrated over the Web. In addition, bibliographic data enriched with Linked Data could offer richer navigational control and access points for users. With Linked Data principles, metadata from libraries could also become harvestable by search engines, transforming dormant catalogs and digital collections into active knowledge repositories. Thus experimenting with Linked Data using existing bibliographic metadata holds the potential to empower libraries to harness the reach of commercial search engines to continuously discover, navigate, and obtain new domain specific knowledge resources on the basis of their verified metadata. The initial part of the paper introduces BIBFRAME and discusses Linked Data in the context of libraries. The final part of this paper outlines a step-by-step process for implementing BIBFRAME with existing library metadata.

TL;DR: The results suggest that undergraduate students are able to deploy systematic evaluations of Web resources and this is crucial for achieving learning.
Abstract: When searching and using resources on the Web, students have to evaluate Web pages in terms of relevance and reliability. This evaluation can be done in a more or less systematic way, by either considering deep or superficial cues of relevance and reliability. The goal of this study was to examine how systematic students are when evaluating Web pages. Forty-two undergraduate students performed a Web research task. They were provided with a search-engine results page including 12 Web pages, which were relevant/irrelevant and reliable/unreliable. The students had to navigate the pages for 30 min to prepare for a subsequent test on a target topic. Their navigation behaviors were video-recorded and analyzed. The findings revealed that the students were not systematic when accessing the pages: They accessed more unreliable pages than reliable pages. The pattern was different when considering study time: The students allocated more time to relevant and reliable pages. Finally, allocating additional time to relevant Web pages was associated with better learning from the materials. Overall, the results suggest that undergraduate students are able to deploy systematic evaluations of Web resources and this is crucial for achieving learning.

TL;DR: In this paper, a peer-to-peer system for sharing resources among remote repositories is proposed, where a request is received to create, read, update, update or delete a resource stored in a content repository.
Abstract: A method, system and computer program product for sharing resources among remote repositories. In a shared file system, a resource identifier and metadata are created for a resource, where the resource identifier is stored in a lock file in a shared volume accessible by the remote repositories. The lock file is then released in response to distributing the associated resource to the remote repositories. Alternatively, in a peer-to-peer system, a request is received to create, read, update or delete a resource stored in a content repository. A resource name, a resource version and/or a resource fingerprint are received in connection with the request to create, read, update or delete the resource in the content repository. A determination is then made as to whether the received resource name, resource version and/or resource fingerprint matches the respective resource name, resource version and/or resource fingerprint stored in a node graph for the resource.

TL;DR: A two-level resource management architecture is proposed, where the necessary information about applications and resources are represented with machine-interpretable semantic descriptions based on the Semantic Web technologies, which are very promising for managing mixed criticality applications in IoT.
Abstract: We believe that the next big step in the field of Internet of Things (IoT) is to realize a virtual computing platform that provides access to heterogeneous group of device resources present in our living environments. By enabling 3rd party developers to access sensor and actuator resources present in a given environment in a same way they can access resources of a single mobile phone, the virtual computing platform would open a new market for the 3rd party IoT applications like the smart phones have done for mobile apps. To accomplish this vision, the virtual computing platform must be able to manage resource sharing between applications with differing criticality requirements for ensuring that the whole IoT system runs optimally. The main challenge is that the approach should be generic and extendable for future needs. To tackle this issue, we propose a two-level resource management architecture, where the necessary information about applications and resources are represented with machine-interpretable semantic descriptions based on the Semantic Web technologies. At the system level, these descriptions are used by the global resource manager for allocating resources to the applications based on their criticality and needs. At local level, each device is assigned with a local resource manager that schedules the access to resources provided by the device so that the performance of the more critical applications could be optimized at the expense of the less critical ones. To evaluate our approach in practice, we have implemented a reference implementation of the proposed architecture and demonstrated it through several applications with differing criticality levels. The results are very promising for managing mixed criticality applications in IoT.

Abstract: A method for managing a resource configuration of a heterogeneously managed computer system. During processing of a resource management request, retrieving a set of resource tags are retrieved. Each resource tag associates a local resource identifier that is assigned within a first configuration management domain with an index identifier that is assigned within a second configuration management naming domain. The retrieved tags are mutually associated utilizing the index identifiers to generating a system configuration map. The resource management request is compared with the system configuration map to identify target resources and corresponding target resource information. One or more resource queries are generated based on the identified target resource and corresponding target resource information.

TL;DR: Experimental results showed that the strategies proposed to associate tags with conceptual entities allow improving resource classification results, outperforming traditional approaches based on bag-of-words representations.
Abstract: User-generated annotations in tagging or bookmarking sites such as Flickr or Delicious can provide a promising and interesting source of information for aiding tasks such as Web resource classification. However, the use of tags brings up some challenges. Since there are no constraints on the terms that can be used for tagging, noise and ambiguity are introduced when users annotate resources. Moreover, traditional bag-of-words representations ignore connections between terms and, thus, are affected by synonymity and hyponymia. Althougth tag-based representations are a valuable source for classifying resources, the problems associated with the unsupervised nature of tags may hinder classification results. This paper presents an approach for semantically analysing social annotations in order to attain enriched concept-based representations of Web resources. Representations are enriched with concepts extracted from WordNet and Wikipedia to overcome problems caused by natural language as well as enhancing the quality of information available for performing an effective classification of resources. Several strategies for tag pre-processing, concept disambiguation and incorporation of semantic entities to representations are discussed and evaluated in this paper. Experimental results showed that the strategies proposed to associate tags with conceptual entities allow improving resource classification results, outperforming traditional approaches based on bag-of-words representations.

TL;DR: This paper analyzes access permission control mechanism considering both the WoT characteristics and the REST-compliant resource-oriented Web architecture, and presents web-resource structure forAccess permission control, and describes an exemplary procedure in detail.
Abstract: The Web of Things (WoT) research is exploring ways on the interoperation among the smart things, since the Web has proven its potentials as open communication environment for accommodating a variety of Web resources. The Web technologies has enabled the Web-enabled devices to publish and exchange their resource information over the Web, whereas the Web-enabled devices should cope with the security threat regarding the information exposures over the Web, particularly, access permissions for the resources about the things. Thus, in this paper we analyse access permission control mechanism considering both the WoT characteristics and the REST-compliant resource-oriented Web architecture. In contrast to existing access control logics, the proposed mechanism utilizes not only the requester information such as the typical identity and the internet addresses, but also the context of the thing itself. Based on this mechanism, we present web-resource structure for access permission control, and describe an exemplary procedure in detail. This research contributes to the flexible and decentralized access permission control for WoT.

TL;DR: This work proposes to share annotations over a minimal web interface that conforms to the Representational State Transfer architectural style and uses the JSON for Linking Data representation (JSON-LD).
Abstract: Annotations are increasingly created and shared online and connected with web resources such as databases of real-world entities. Recent collaborative efforts to provide interoperability between online annotation tools and resources have introduced the Open Annotation (OA) model, a general framework for representing annotations based on web standards. Building on the OA model, we propose to share annotations over a minimal web interface that conforms to the Representational State Transfer architectural style and uses the JSON for Linking Data representation (JSON-LD). We introduce tools supporting this approach and apply it to several existing annotation clients and servers, demonstrating direct interoperability between tools and resources that were previously unable to exchange information. The specification and tools are available from http://restoa.github.io/.
TL;DR: How information on service and reagent providers of relevant technologies is made available on BARCdb is described, and how this resource may contribute to strengthening biomedical research in academia and in the biotechnology and pharmaceutical industries.
Abstract: We report the development of a new database of technology services and products for analysis of biobank samples in biomedical research. BARCdb, the Biobanking Analysis Resource Catalogue (http://www.barcdb.org), is a freely available web resource, listing expertise and molecular resource capabilities of research centres and biotechnology companies. The database is designed for researchers who require information on how to make best use of valuable biospecimens from biobanks and other sample collections, focusing on the choice of analytical techniques and the demands they make on the type of samples, pre-analytical sample preparation and amounts needed. BARCdb has been developed as part of the Swedish biobanking infrastructure (BBMRI.se), but now welcomes submissions from service providers throughout Europe. BARCdb can help match resource providers with potential users, stimulating transnational collaborations and ensuring compatibility of results from different labs. It can promote a more optimal use of European resources in general, both with respect to standard and more experimental technologies, as well as for valuable biobank samples. This article describes how information on service and reagent providers of relevant technologies is made available on BARCdb, and how this resource may contribute to strengthening biomedical research in academia and in the biotechnology and pharmaceutical industries.

Abstract: The social media revolution is having a dramatic effect on the world of scientific publication. Scientists now publish their research interests, theories and outcomes across numerous channels, including personal blogs and other thematic web spaces where ideas, activities and partial results are discussed. Accordingly, information systems that facilitate access to scientific literature must learn to cope with this valuable and varied data, evolving to make this research easily discoverable and available to end users. In this paper we describe the incremental process of discovering web resources in the domain of agricultural science and technology. Making use of Linked Open Data methodologies, we interlink a wide array of custom-crawled resources with the AGRIS bibliographic database in order to enrich the user experience of the AGRIS website. We also discuss the SemaGrow Stack, a query federation and data integration infrastructure used to estimate the semantic distance between crawled web resources and AGRIS.
TL;DR: This paper is focused on the study of different ranking techniques and shows advantages, limitations and comparison of these techniques.
Abstract: Identification of opinion leader is very important in this world of internet because with the identified opinion leaders in any application area such as Knowledge related sites, followers or other individuals can get valuable information more efficiently through direct communication with opinion leader. Internet i.e. WWW (World Wide Web) is the huge and very popular way of information broadcasting and communication. This huge www has so many web structures and within one structure there would be millions of web resources (contents, links) may exist. There are large numbers of webpages on the web which are linked to each other through hyperlinks. So, graph based techniques can be used to identify opinion leader i.e. techniques for ranking the results to provide the "best" results first. Different algorithms are there which are used for link analysis i.e. for ranking the web pages like PageRank (PR), Weighted PageRank (WPR), Hyperlink-Induced Topic Search (HITS), Spamming Resistant Expertise Analysis and Ranking (SPEAR) etc. This paper is focused on the study of different ranking techniques. Further this paper shows advantages, limitations and comparison of these techniques. General Terms Data and Web Mining.
