    Abstract
    In this thesis we propose three new word association measures for multi-word term extraction. We combine these association measures with LocalMaxs algorithm in our extraction model and compare the results of different multi-word term extraction methods. Our approach is language and domain independent and requires no training data. It can be applied to such tasks as text summarization, information retrieval, and document classification. We further explore the potential of using multi-word terms as an effective representation for general web-page summarization. We extract multi-word terms from human written summaries in a large collection of web-pages, and generate the summaries by aligning document words with these multi-word terms. Our system applies machine translation technology to learn the aligning process from a training set and focuses on selecting high quality multi-word terms from human written summaries to generate suitable results for web-page summarization.

    Abstract
    While classifications are heavily used to categorize web content, the evolution of the web foresees a more formal structure - ontology - which can serve this purpose. Ontologies are core artifacts of the Semantic Web which enable machines to use inference rules to conduct automated reasoning on data. Lightweight ontologies bridge the gap between classifications and ontologies. A lightweight ontology (LO) is an ontology representing a backbone taxonomy where the concept of the child node is more specific than the concept of the parent node. Formal lightweight ontologies can be generated from their informal ones. The key applications of formal lightweight ontologies are document classification, semantic search, and data integration. However, these applications suffer from the following problems: the disambiguation accuracy of the state of the art NLP tools used in generating formal lightweight ontologies from their informal ones; the lack of background knowledge needed for the formal lightweight ontologies; and the limitation of ontology reuse. In this dissertation, we propose a novel solution to these problems in formal lightweight ontologies; namely, faceted lightweight ontology (FLO). FLO is a lightweight ontology in which terms, present in each node label, and their concepts, are available in the background knowledge (BK), which is organized as a set of facets. A facet can be defined as a distinctive property of the groups of concepts that can help in differentiating one group from another. Background knowledge can be defined as a subset of a knowledge base, such as WordNet, and often represents a specific domain.

    Abstract
    Computer users today rely on a wide variety of software tools to manage an ever-increasing amount of information and resources. We developed the Global Information Gatherer (GIG) system to help students in higher education manage, understand, and keep their academic work. GIG provides a comprehensive, integrative interface through which students can access commonly used programs and simultaneously record notes and organize files. This article presents an overview of the GIG program before describing a large-scale, longitudinal, and unrestricted evaluation of its use. We investigate how such a program is received by nontechnical users, which features prove most helpful to students as they work to complete their everyday tasks, how it compares to other software solutions, and whether it helps with information assimilation and management tasks. Results of our study indicate that participants have a strong preference for software that minimizes program window manipulation, facilitates information consolidation and organization, provides citation support and integrated web browsing, and incorporates a progressive user interface design. When comparing GIG to their normal way of accomplishing tasks, students gave particularly high marks for its ability to save materials from the web, gather sources for academic research, manage windows, and copy/paste from the web. On the third and final survey of our evaluation, we learned that a majority (>70%) of remaining participants believed that GIG was helpful for managing and making sense of the large volume of information to which they are exposed everyday, and over half (55%) said they would continue using the software if it was freely available.

    Abstract
    Ontologies are viewed as the silver bullet for many applications, but in open or evolving systems, different parties can adopt different ontologies. This increases heterogeneity problems rather than reducing heterogeneity. This book proposes ontology matching as a solution to the problem of semantic heterogeneity, offering researchers and practitioners a uniform framework of reference to currently available work. The techniques presented apply to database schema matching, catalog integration, XML schema matching and more. Ontologies tend to be found everywhere. They are viewed as the silver bullet for many applications, such as database integration, peer-to-peer systems, e-commerce, semantic web services, or social networks. However, in open or evolving systems, such as the semantic web, different parties would, in general, adopt different ontologies. Thus, merely using ontologies, like using XML, does not reduce heterogeneity: it just raises heterogeneity problems to a higher level. Euzenat and Shvaiko's book is devoted to ontology matching as a solution to the semantic heterogeneity problem faced by computer systems. Ontology matching aims at finding correspondences between semantically related entities of different ontologies. These correspondences may stand for equivalence as well as other relations, such as consequence, subsumption, or disjointness, between ontology entities. Many different matching solutions have been proposed so far from various viewpoints, e.g., databases, information systems, artificial intelligence. With Ontology Matching, researchers and practitioners will find a reference book which presents currently available work in a uniform framework. In particular, the work and the techniques presented in this book can equally be applied to database schema matching, catalog integration, XML schema matching and other related problems. The objectives of the book include presenting (i) the state of the art and (ii) the latest research results in ontology matching by providing a detailed account of matching techniques and matching systems in a systematic way from theoretical, practical and application perspectives.

    Abstract
    I need to measure semantic similarity between CSO ontology concepts, depending on Ontology structure (concept path, depth, least common subsumer (LCS) ...). CSO (Computer Science Ontology) is a large-scale ontology of research areas. A concepts in CSO may have multiple parents/super concepts (i.e. a concept may be a child of many other concepts), e.g. : (world wide web) is parent of (semantic web) (semantics) is parent of (semantic web) I found some measures that meet my needs, but the papers proposing these measures are not cited, so i got hesitated. I also found a measure that depends on weighted edges, but multiple inheritance (super concepts) is not considered..

    Abstract
    Knowledge organization is needed everywhere. Its importance is marked by its pervasiveness. This paper will show many areas, tasks, and functions where proper use of knowledge organization, construed as broadly as the term implies, provides support for learning and understanding, for sense making and meaning making, for inference, and for discovery by people and computer programs and thereby will make the world a better place. The paper focuses not on metadata but rather on structuring and representing the actual data or knowledge itself and argues for more communication between the largely separated KO, ontology, data modeling, and semantic web communities to address the many problems that need better solutions. In particular, the paper discusses the application of knowledge organization in knowledge bases for question answering and cognitive systems, knowledge bases for information extraction from text or multimedia, linked data, big data and data analytics, electronic health records as one example, influence diagrams (causal maps), dynamic system models, process diagrams, concept maps, and other node-link diagrams, information systems in organizations, knowledge organization for understanding and learning, and knowledge transfer between domains. The paper argues for moving beyond triples to a more powerful representation using entities and multi-way relationships but not attributes.

    Abstract
    The main purpose of this book is to sum up the vital and highly topical research issue of knowledge representation on the Web and to discuss novel solutions by combining benefits of folksonomies and Web 2.0 approaches with ontologies and semantic technologies. This book contains an overview of knowledge representation approaches in past, present and future, introduction to ontologies, Web indexing and in first case the novel approaches of developing ontologies. This title combines aspects of knowledge representation for both the Semantic Web (ontologies) and the Web 2.0 (folksonomies). Currently there is no monographic book which provides a combined overview over these topics. focus on the topic of using knowledge representation methods for document indexing purposes. For this purpose, considerations from classical librarian interests in knowledge representation (thesauri, classification schemes etc.) are included, which are not part of most other books which have a stronger background in computer science.

    Rez. in: iwp 62(2011) H.4, S.205-206 (C. Carstens): "Welche Arten der Wissensrepräsentation existieren im Web, wie ausgeprägt sind semantische Strukturen in diesem Kontext, und wie können soziale Aktivitäten im Sinne des Web 2.0 zur Strukturierung von Wissen im Web beitragen? Diesen Fragen widmet sich Wellers Buch mit dem Titel Knowledge Representation in the Social Semantic Web. Der Begriff Social Semantic Web spielt einerseits auf die semantische Strukturierung von Daten im Sinne des Semantic Web an und deutet andererseits auf die zunehmend kollaborative Inhaltserstellung im Social Web hin. Weller greift die Entwicklungen in diesen beiden Bereichen auf und beleuchtet die Möglichkeiten und Herausforderungen, die aus der Kombination der Aktivitäten im Semantic Web und im Social Web entstehen. Der Fokus des Buches liegt dabei primär auf den konzeptuellen Herausforderungen, die sich in diesem Kontext ergeben. So strebt die originäre Vision des Semantic Web die Annotation aller Webinhalte mit ausdrucksstarken, hochformalisierten Ontologien an. Im Social Web hingegen werden große Mengen an Daten von Nutzern erstellt, die häufig mithilfe von unkontrollierten Tags in Folksonomies annotiert werden. Weller sieht in derartigen kollaborativ erstellten Inhalten und Annotationen großes Potenzial für die semantische Indexierung, eine wichtige Voraussetzung für das Retrieval im Web. Das Hauptinteresse des Buches besteht daher darin, eine Brücke zwischen den Wissensrepräsentations-Methoden im Social Web und im Semantic Web zu schlagen. Um dieser Fragestellung nachzugehen, gliedert sich das Buch in drei Teile. . . .
    Insgesamt besticht das Buch insbesondere durch seine breite Sichtweise, die Aktualität und die Fülle an Referenzen. Es ist somit sowohl als Überblickswerk geeignet, das umfassend über aktuelle Entwicklungen und Trends der Wissensrepräsentation im Semantic und Social Web informiert, als auch als Lektüre für Experten, für die es vor allem als kontextualisierte und sehr aktuelle Sammlung von Referenzen eine wertvolle Ressource darstellt."

    Abstract
    This chapter focuses on the Internet working environment of Knowledge Workers through the customization of the Web browser on their computer. Given that a Web browser is designed to be used by anyone browsing the Internet, its initial configuration must meet generic needs such as reading a Web page, searching for information, and bookmarking. In the absence of a universal solution that meets the specific needs of each user, browser developers offer additional programs known as extensions, or add-ons. Among the various browsers that can be modified with add-ons, Mozilla's Firefox is perhaps the one that first springs to mind; indeed, Mozilla has built the Firefox brand around these extensions. Using this example, and also considering the browsers Google Chrome, Internet Explorer, Opera and Safari, the author will attempt to demonstrate the potential of Web browsers in terms of the resources they can offer when they are customizable and available within the working environment of a Knowledge Worker.

    Abstract
    We present a framework for keyphrase extraction from scientific journals in diverse research fields. While journal articles are often provided with manually assigned keywords, it is not clear how to automatically extract keywords and measure their significance for a set of journal articles. We compare extracted keyphrases from journals in the fields of astrophysics, mathematics, physics, and computer science. We show that the presented statistics-based framework is able to demonstrate differences among journals, and that the extracted keyphrases can be used to represent journal or conference research topics, dynamics, and specificity.

    Abstract
    In this paper we describe the development of the Web Index linked data portal that represents statistical index data and the computations from which it has been obtained. The Web Index is a multi-dimensional measure of the World Wide Web's contribution to development and human rights globally. It covers 81 countries and incorporates indicators that assess several areas like universal access; freedom and openness; relevant content; and empowerment. In order to empower the Web Index transparency, we established as an internal requirement that every published data could be externally verified. The verification could be that it was just raw data obtained from a secondary source, in which case, the system must provide a link to that data source or that the value has been internally computed, in which case, the system provides links to the values from which it has been calculated. The resulting portal contains data that can be tracked to its sources so an external agent can validate the whole index computation process. We describe the different aspects involved in the development of the WebIndex data portal that also offers new linked data visualization tools. Although in this paper we concentrate on the Web Index development, this approach can be generalized to other projects which involve the publication of externally verifiable computations.

    Abstract
    The Semantic Web consists of data structured for use by computer programs, such as data sets made available under the Linked Open Data initiative. Much of this data is structured following the entity-relationship model encoded in RDF for syntactic interoperability. For semantic interoperability, the semantics of the relationships used in any given dataset needs to be made explicit. Ultimately this requires an inventory of these relationships structured around a relation ontology. This talk will outline a blueprint for such an inventory, including a format for the description/definition of binary and n-ary relations, drawing on ideas put forth in the classification and thesaurus community over the last 60 years, upper level ontologies, systems like FrameNet, the Buffalo Relation Ontology, and an analysis of linked data sets.

    Abstract
    Nowadays, tremendous information sources are preserved, ranging from those of a traditional nature like libraries and museums to new formats like electronic databases and the World Wide Web. Making these sources consistent, easily accessible, and as complete as possible is challenging. Almost a century ago, people like Paul Otlet were already fully aware of this need and tried to develop ways of making human knowledge more accessible using the resources and technology available at that time. Otlet's ideas about a Universal Network of Documentation and the Universal Book are clear examples of such efforts. Computer science currently provides the means to build digital spaces that consist of (multimedia) information sources connected through the Internet. In this article, we give a nontechnical overview of the current state of the art in information management. Next, we focus on those aspects of Otlet's work that deal with the organization of knowledge and information sources. Then we study the potential connections between Otlet's work and the state of the art of computerized information management from a computer scientist's point of view. Finally, we consider some of the problems and challenges that information management still faces today and what computer science professionals have in common with, and can still learn from, Otlet and his work.

    Abstract
    This is a practical guide to using web metrics to measure impact and demonstrate value. The web provides an opportunity to collect a host of different metrics, from those associated with social media accounts and websites to more traditional research outputs. This book is a clear guide for library and information professionals as to what web metrics are available and how to assess and use them to make informed decisions and demonstrate value. As individuals and organizations increasingly use the web in addition to traditional publishing avenues and formats, this book provides the tools to unlock web metrics and evaluate the impact of this content. The key topics covered include: bibliometrics, webometrics and web metrics; data collection tools; evaluating impact on the web; evaluating social media impact; investigating relationships between actors; exploring traditional publications in a new environment; web metrics and the web of data; the future of web metrics and the library and information professional. The book will provide a practical introduction to web metrics for a wide range of library and information professionals, from the bibliometrician wanting to demonstrate the wider impact of a researcher's work than can be demonstrated through traditional citations databases, to the reference librarian wanting to measure how successfully they are engaging with their users on Twitter. It will be a valuable tool for anyone who wants to not only understand the impact of content, but demonstrate this impact to others within the organization and beyond.
