    Abstract
    Die historischen Wurzeln des Semantic Web reichen zurück in die Artificial Intelligence Forschung der 1960er und -70er Jahre. Konzepte aus der Light Weight Artificial Intelligence wie Frames, Microworlds und Heuristic Programming stellten erste Versuche der maschinenverarbeitbaren Wissensrepräsentation dar. Hier ging es nicht darum, intelligentes Verhalten zu simulieren, sondern Methoden zu entwickeln, die den Menschen in seiner Entscheidungsfindung unterstützen. Durch die inhaltliche Beschreibung (semantische Anreicherung) von Datenbeständen mit maschinenlesbaren Metadaten und Scripts wurden Maschinen in die Lage versetzt autonom Daten zu verarbeiten. Der Computer sollte in der Lage sein, den Kontext, in dem Daten erzeugt und abgelegt werden, zu "verstehen" und darauf basierend für den Nutzer relevante Daten zu selektieren, zu verarbeiten und auszugeben.

    Abstract
    We present YAGO, a light-weight and extensible ontology with high coverage and quality. YAGO builds on entities and relations and currently contains more than 1 million entities and 5 million facts. This includes the Is-A hierarchy as well as non-taxonomic relations between entities (such as hasWonPrize). The facts have been automatically extracted from Wikipedia and unified with WordNet, using a carefully designed combination of rule-based and heuristic methods described in this paper. The resulting knowledge base is a major step beyond WordNet: in quality by adding knowledge about individuals like persons, organizations, products, etc. with their semantic relationships - and in quantity by increasing the number of facts by more than an order of magnitude. Our empirical evaluation of fact correctness shows an accuracy of about 95%. YAGO is based on a logically clean model, which is decidable, extensible, and compatible with RDFS. Finally, we show how YAGO can be further extended by state-of-the-art information extraction techniques.

    Abstract
    How information resources can be meaningfully related has been addressed in contexts from bibliographic entries to hyperlinks and, more recently, linked data. The genre structure and relationships among genre structure constituents shed new light on organizing information by purpose or function. This study examines the relationships among a set of functional units previously constructed in a taxonomy, each of which is a chunk of information embedded in a document and is distinct in terms of its communicative function. Through a card-sort study, relationships among functional units were identified with regard to their occurrence and function. The findings suggest that a group of functional units can be identified, collocated, and navigated by particular relationships. Understanding how functional units are related to each other is significant in linking information pieces in documents to support finding, aggregating, and navigating information in a distributed information environment.

    Abstract
    Purpose - This paper investigates the semantic structure underlying DBpedia, one of the largest and most heavily used datasets in the current Linked Open Data (LOD) landscape. The analysis attempts to shed light on this new type of knowledge organization tool. Design/methodology/approach - The research followed a case study methodology to analyze DBpedia using the domain of jazz as the application scenario. Findings - The study reveals an evolving knowledge organization tool where different descriptive and classification approaches are employed concurrently. The semantic constructs employed in the DBpedia knowledge base vary significantly in terms of their degree of formalization, stability, cohesiveness and consistency. As such, they challenge the tolerance threshold for data quality and the traditional notion of authority control. Research limitations/implications - The analysis is conducted on a limited portion of a large knowledge base. Initial findings provide a basis for further research and study. Practical implications - Revealing the knowledge organization underlying DBpedia increases the understanding of its power, its limitations and its implications for the new semantic context provided by LOD. Having an understanding of the range of entities and properties available enables LOD users to formulate queries with higher precision. Originality/value - This study is the first conducted from the perspective of the knowledge organization community.
