    Abstract
    The basic goal of education within a discipline is to transform a novice into an expert. This entails moving the novice toward the "semantic space" that the expert inhabits-the space of concepts, meanings, vocabularies, and other intellectual constructs that comprise the discipline. Metadata is significant to this goal in digitally mediated education environments. Encoding the experts' semantic space not only enables the sharing of semantics among discipline scientists, but also creates an environment that bridges the semantic gap between the common vocabulary of the novice and the granular descriptive language of the seasoned scientist (Greenberg, et al, 2005). Developments underlying the Semantic Web, where vocabularies are formalized in the Web Ontology Language (OWL), and Web 2.0 approaches of user-generated folksonomies provide an infrastructure for linking vocabulary systems and promoting group learning via metadata literacy. Group learning is a pedagogical approach to teaching that harnesses the phenomenon of "collective intelligence" to increase learning by means of collaboration. Learning a new semantic system can be daunting for a novice, and yet it is integral to advance one's knowledge in a discipline and retain interest. These ideas are key to the "BOT 2.0: Botany through Web 2.0, the Memex and Social Learning" project (Bot 2.0).72 Bot 2.0 is a collaboration involving the North Carolina Botanical Garden, the UNC SILS Metadata Research center, and the Renaissance Computing Institute (RENCI). Bot 2.0 presents a curriculum utilizing a memex as a way for students to link and share digital information, working asynchronously in an environment beyond the traditional classroom. Our conception of a memex is not a centralized black box but rather a flexible, distributed framework that uses the most salient and easiest-to-use collaborative platforms (e.g., Facebook, Flickr, wiki and blog technology) for personal information management. By meeting students "where they live" digitally, we hope to attract students to the study of botanical science. A key aspect is to teach students scientific terminology and about the value of metadata, an inherent function in several of the technologies and in the instructional approach we are utilizing. This poster will report on a study examining the value of both folksonomies and taxonomies for post-secondary college students learning plant identification. Our data is drawn from a curriculum involving a virtual independent learning portion and a "BotCamp" weekend at UNC, where students work with digital plan specimens that they have captured. Results provide some insight into the importance of collaboration and shared vocabulary for gaining confidence and for student progression from novice to expert in botany.

    Abstract
    Semantic Web knowledge representation standards, and in particular RDF and OWL, often come endowed with a formal semantics which is considered to be of fundamental importance for the field. Reasoning, i.e., the drawing of logical inferences from knowledge expressed in such standards, is traditionally based on logical deductive methods and algorithms which can be proven to be sound and complete and terminating, i.e. correct in a very strong sense. For various reasons, though, in particular the scalability issues arising from the ever increasing amounts of Semantic Web data available and the inability of deductive algorithms to deal with noise in the data, it has been argued that alternative means of reasoning should be investigated which bear high promise for high scalability and better robustness. From this perspective, deductive algorithms can be considered the gold standard regarding correctness against which alternative methods need to be tested. In this paper, we show that it is possible to train a Deep Learning system on RDF knowledge graphs, such that it is able to perform reasoning over new RDF knowledge graphs, with high precision and recall compared to the deductive gold standard.

    Abstract
    The first section of "Semantic Web and Education" surveys the basic aspects and features of the Semantic Web. After this basic review, the book turns its focus to its primary topic of how Semantic Web developments can be used to build attractive and more successful education applications. The book analytically discusses the technical areas of architecture, metadata, learning objects, software engineering trends, and more. Integrated with these technical topics are the examinations of learning-oriented topics such as learner modeling, collaborative learning, learning management, learning communities, ontological engineering of web-based learning, and related topics. The result is a thorough and highly useful presentation on the confluence of the technical aspects of the Semantic Web and the field of Education or the art of teaching. The book will be of considerable interest to researchers and students in the fields Information Systems, Computer Science, and Education.

    Footnote
    Semantic web technologies are explained, and ontology representation is emphasized. There is an excellent summary of the fundamental theory behind applying a knowledge-engineering approach to vision problems. This summary represents the concept of the semantic web and multimedia content analysis. A definition of the fuzzy knowledge representation that can be used for realization in multimedia content applications has been provided, with a comprehensive analysis. The second part of the book introduces the multimedia content analysis approaches and applications. In addition, some examples of methods applicable to multimedia content analysis are presented. Multimedia content analysis is a very diverse field and concerns many other research fields at the same time; this creates strong diversity issues, as everything from low-level features (e.g., colors, DCT coefficients, motion vectors, etc.) up to the very high and semantic level (e.g., Object, Events, Tracks, etc.) are involved. The second part includes topics on structure identification (e.g., shot detection for video sequences), and object-based video indexing. These conventional analysis methods are supplemented by results on semantic multimedia analysis, including three detailed chapters on the development and use of knowledge models for automatic multimedia analysis. Starting from object-based indexing and continuing with machine learning, these three chapters are very logically organized. Because of the diversity of this research field, including several chapters of recent research results is not sufficient to cover the state of the art of multimedia. The editors of the book should write an introductory chapter about multimedia content analysis approaches, basic problems, and technical issues and challenges, and try to survey the state of the art of the field and thus introduce the field to the reader.

    Abstract
    This article shares a vision of the enterprise of cataloging and the role of catalogers and metadata librarians in the twenty-first century. The revolutionary opportunities now presented by Semantic Web technologies liberate catalogers from their historically analog-based static world, re-conceptualize it, and transform it into a world of high dimensionality and fluidity. By presenting illustrative examples of innovative metadata creation and manipulation, such as non-MARC name authority records, we seek to contribute to the libraries' mission with innovative projects that enable discovery, development, communication, learning, and creativity, and hold promise to exceed users' expectations.

    Abstract
    In diesem Kapitel wird behandelt, welche Rolle semantische Technologien bei der Integration von Arbeits- und Lernprozessen an einem modernen IT-basierten Arbeitsplatz spielen können. Die Reduktion der Wissenshalbwertszeit und der rasche Wandel von Technologien stellt die Forderung nach Life-Long-Learning und kontinuierlicher Kompetenzentwicklung immer mehr in den Vordergrund. Es wird dabei zunehmend deutlicher, dass diese Weiterentwicklung am Arbeitsplatz im Kontext der Arbeitsprozesse stattfinden muss, um die geforderte Geschwindigkeit und Qualität von Wissenstransfer sicherzustellen. Um diese Integration auch gerade in virtuellen Umgebungen zu erzielen, ist der Einsatz von semantischen Technologien unumgänglich. Aufbauend auf Beschreibungen aus anderen Kapiteln zum Thema Geschäftsprozesse & semantische Technologien wird hier besonders auf das Konzept des (Arbeits-)Kontextes von Wissensarbeitern eingegangen. Im ersten Schritt werden Nutzenpotenziale der Integration von Arbeiten und Lernen formuliert. Danach stellen wir Anwendungen von Technologien des Semantic Web vor, die geeignet sind, diese Nutzenpotenziale auszuschöpfen und diskutieren technische Herausforderungen, die sich in der Realisierung der vorgestellten Technologien ergeben können.

    Abstract
    The power of search is with no doubt one of the main aspects for the success of the Web. Currently available search engines on the Web allow to return results with a high precision. Nevertheless, if we limit our attention only to lookup search we are missing another important search task. In exploratory search, the user is willing not only to find documents relevant with respect to her query but she is also interested in learning, discovering and understanding novel knowledge on complex and sometimes unknown topics. In the paper we address this issue presenting LED, a web based system that aims to improve (lookup) Web search by enabling users to properly explore knowledge associated to her query. We rely on DBpedia to explore the semantics of keywords within the query thus suggesting potentially interesting related topics/keywords to the user.

    Abstract
    In the area of digital library services, the access to subject-specific metadata of scholarly publications is of utmost interest. One of the most prevalent approaches for metadata exchange is the XML-based Open Archive Initiative (OAI) Protocol for Metadata Harvesting (OAI-PMH). However, due to its loose requirements regarding metadata content there is no strict standard for consistent subject indexing specified, which is furthermore needed in the digital library domain. This contribution addresses the problem of automatic enhancement of OAI metadata by means of the most widely used universal classification schemes in libraries-the Dewey Decimal Classification (DDC). To be more specific, we automatically classify scientific documents according to the DDC taxonomy within three levels using a machine learning-based classifier that relies solely on OAI metadata records as the document representation. The results show an asymmetric distribution of documents across the hierarchical structure of the DDC taxonomy and issues of data sparseness. However, the performance of the classifier shows promising results on all three levels of the DDC.

    Abstract
    Primitive thinking forms affected the organization of knowledge, and at a later date writing also affected organization. Currently, the web requires new forms of learning and knowledge; with the globalization of information, connectivity and virtuality have a bearing on human thought. Digital thinking is shaping our reality and its organizational form. Natural memory, considered to be a process that requires the structure of natural language and human capabilities, is interwoven with a subject and a conscience; memory preserved through writing required other tools to assist it, and classifications, cataloguing, organization or other KOS were created. The new tool for recovering digital memory is the semantic web. This points to information's future on the Internet and seems to approach the utopia of global, organized information and attempts to give the website greater significance. The Web 3.0 incorporates a proliferation of languages, concepts and tools that are difficult to govern and are created by users. The semantic web seems to be a natural evolution of the participative web in which we find ourselves, and if an effective combination is achieved between the inclusion of semantic content in web pages and the use of artificial intelligence it will be a revolution; semantic codification will be a fact when it is totally automated. Based on this, a collective digital intelligence is being constituted. We find ourselves before intelligent multitudes with broad access to enormous amounts of information. The intelligent multitude emerges when technologies interconnect. In this global interconnection of semantic information an exponential pattern of technological growth can take place.
