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

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.

Wer den großen Google-Konkurrenten erst einmal im Blindtest auf den Zahn fühlen will, kann das unter http://blindsearch.fejus.com tun. Die Suchergebnisse werden im gleichen Design in drei Spal- ten nebeneinander dargestellt. Erst, wenn der Nutzer sein Votum abgegeben hat, in welcher Spalte die seiner Meinung nach besten Ergebnisse stehen, lüftet die Seite das Geheimnis und zeigt die Logos von Bing, Yahoo und Google an. Der Verein Suma zieht das Fazit, dass "The Big Three" qualitativ gleichwertig seien. Am Tempo gibt es bei den großen Suchmaschinen nichts zu bemängeln. Alle drei spucken ihre Ergebnisse zügig aus. Google und Yahoo zeigen beim Tippen Suchvorschläge an und verfügen über einen Kinder- und Jugendschutzfilter. Letzterer lässt sich auch bei Bing einschalten. Auf die Booleschen Operatoren ("AND", "OR" etc.), die Suchbegriffe logisch verknüpfen, verstehen sich die meisten Suchmaschinen. Yahoo bietet zusätzlich die Suche mit haus- gemachten Abkürzungen an. Shortcuts für die fixe Suche nach Aktienkursen, Call-byCall-Vorwahlen, dem Wetter oder eine Taschenrechnerfunktion finden sich unter http://de.search.yahoo.com/info/shortcuts. Vergleichbar ist das Funktionsangebot von Google, das unter www.google.com/intl/de/help/features.html aufgelistet ist. Das Unternehmen bietet auch die Volltextsuche in Büchern, eine Suche in wissenschaftlichen Veröffentlichungen oder die Recherche nach öffentlich verfügbarem Programmiercodes an. Bei den großen Maschinen lassen sich in der erweiterten Suche auch Parameter wie Sprachraum, Region, Dateityp, Position des Suchbegriffs auf der Seite, Zeitraum der letzten Aktualisierung und Nutzungsrechte einbeziehen. Ganz so weit ist die deutsche Suche von Ask, die sich noch im Betastudium befindet, noch nicht (http://de.ask.com). Praktisch ist aber die Voran-sicht der Seiten in einem Popup-Fenster beim Mouseover über das Fernglas-Symbol vor den Suchbegriffen. Die globale Ask-Suche (www.ask.com) ist schon weiter und zeigt wie Google direkt auch Bilder zu den relevantesten Foto- und Video-Suchergebnissen an.
Unzählige kleinere und Spezial-Suchmaschinen bieten Einblicke in Ecken des Netzes, zu denen man mit den Großen eher nicht gelangt wä- re. Nach wie vor gibt es auch Verzeichnisdienste. die Seiten in genau beschriebenen Kategorien auflisten. Dazu gehört www.dmoz.org. Um mehrere Maschinen und Verzeichnisdienste gleichzeitig abzufragen, empfehlen sich Metasuchmaschinen. Eine der bekanntesten ist MetaGer, ein Projekt der Universität Hannover. Eine weitere interessante Metasuchmaschine, deren Ergebnisse aber auf Nordamerika zugeschnitten sind, ist www.clusty.com. Wie der Name andeutet, bündelt sie die Suchergebnisse zu logischen Clustern. Auch praktisch: Beim Klick auf die Lupensymbole hinter den Suchergebnissen öffnen sich beliebig viele Vorschauen direkt in der Web- seite. Ob das Googeln ohne Google irgendwann nichts besonderes mehr ist, hängt maßgeblich von den Surfern ab - davon ist man beim Verein für freien Wissenszugang überzeugt: Änderungen seien ,;weniger durch neue Technologien, sondern vor allem durch verändertes Nutzerverhalten aufgrund steigender Informationskompetenz zu erwarten."

Abstract

More and more cultural heritage institutions publish their collections, vocabularies and metadata on the Web. The resulting Web of linked cultural data opens up exciting new possibilities for searching and browsing through these cultural heritage collections. We report on ongoing work in which we investigate the estimation of relevance in this Web of Culture. We study existing measures of semantic distance and how they apply to two use cases. The use cases relate to the structured, multilingual and multimodal nature of the Culture Web. We distinguish between measures using the Web, such as Google distance and PMI, and measures using the Linked Data Web, i.e. the semantic structure of metadata vocabularies. We perform a small study in which we compare these semantic distance measures to human judgements of relevance. Although it is too early to draw any definitive conclusions, the study provides new insights into the applicability of semantic distance measures to the Web of Culture, and clear starting points for further research.

Abstract

Das World Wide Web ist als weltweites Informations- und Kommunikationsmedium etabliert. Neue Technologien erweitern regelmäßig die Nutzungsformen und erlauben es auch unerfahrenen Nutzern, Inhalte zu publizieren oder an Diskussionen teilzunehmen. Daher wird das Web auch als eine gute Dokumentation der heutigen Gesellschaft angesehen. Aufgrund seiner Dynamik sind die Inhalte des Web vergänglich und neue Technologien und Nutzungsformen stellen regelmäßig neue Herausforderungen an die Sammlung von Webinhalten für die Webarchivierung. Dominierten in den Anfangstagen der Webarchivierung noch statische Seiten, so hat man es heute häufig mit dynamisch generierten Inhalten zu tun, die Informationen aus verschiedenen Quellen integrieren. Neben dem klassischen domainorientieren Webharvesting kann auch ein steigendes Interesse aus verschiedenen Forschungsdisziplinen an thematischen Webkollektionen und deren Nutzung und Exploration beobachtet werden. In diesem Artikel werden einige Herausforderungen und Lösungsansätze für die Sammlung von thematischen und dynamischen Inhalten aus dem Web und den sozialen Medien vorgestellt. Des Weiteren werden aktuelle Probleme der wissenschaftlichen Nutzung diskutiert und gezeigt, wie Webarchive und andere temporale Kollektionen besser durchsucht werden können.

Abstract

This paper presents the semantic web, web writing content, web technology, goals of semantic and obligation for the expansion of web 3.0. This paper also shows the different components of semantic web and such as HTTP, HTML, XML, XML Schema, URI, RDF, Taxonomy and OWL. To provide valuable information services semantic web execute the benefits of library functions and also to be the best use of library collection are mention here.
