Abstract

As the amount of biological information and its diversity accumulates massively there is a critical need to facilitate the integration of this data to allow new and unexpected conclusions to be drawn from it. The Semantic Web is a new wave of web- based technologies that allows the linking of data between diverse data sets via standardised data formats (“big data”). Semantic Biology is the application of semantic web technology in the biological domain (including medical and health informatics). The Special Topic encompasses papers in this very broad area, including not only ontologies (development and applications), but also text mining, data integration and data analysis making use of the technologies of the Semantic Web. Ontologies are a critical requirement for such integration as they allow conclusions drawn about biological experiments, or descriptions of biological entities, to be understandable and integratable despite being contained in different databases and analysed by different software systems. Ontologies are the standard structures used in biology, and more broadly in computer science, to hold standardized terminologies for particular domains of knowledge. Ontologies consist of sets of standard terms, which are defined and may have synonyms for ease of searching and to accommodate different usages by different communities. These terms are linked by standard relationships, such as “is_a” (an eye “is_a” sense organ) or “part_of” (an eye is “part_of” a head). By linking terms in this way, more detailed, or granular, terms can be linked to broader terms, allowing computation to be carried out that takes these relationships into account.

Abstract

In this book we show how semantic technologies and in particular the use of ontologies can be employed to address a number of typical challenges in distributed information systems: First, we illustrate how ontologies enable the integration of information across heterogeneous nodes. Second, we show how ontology evolution allows dealing with the dynamics in the information in a consistent manner. Third, we present a model for ontologybased coordination using semantic overlay networks.

Abstract

Metadata is a key aspect of our evolving infrastructure for information management, social computing, and scientific collaboration. DC-2008 will focus on metadata challenges, solutions, and innovation in initiatives and activities underlying semantic and social applications. Metadata is part of the fabric of social computing, which includes the use of wikis, blogs, and tagging for collaboration and participation. Metadata also underlies the development of semantic applications, and the Semantic Web — the representation and integration of multimedia knowledge structures on the basis of semantic models. These two trends flow together in applications such as Wikipedia, where authors collectively create structured information that can be extracted and used to enhance access to and use of information sources. Recent discussion has focused on how existing bibliographic standards can be expressed as Semantic Web vocabularies to facilitate the ingration of library and cultural heritage data with other types of data. Harnessing the efforts of content providers and end-users to link, tag, edit, and describe their information in interoperable ways (”participatory metadata”) is a key step towards providing knowledge environments that are scalable, self-correcting, and evolvable. DC-2008 will explore conceptual and practical issues in the development and deployment of semantic and social applications to meet the needs of specific communities of practice.

Abstract

Dienstorientierte Architekturen werden ihr volles Potenzial nur dann entfalten können, wenn es gelingt, Dienste fallweise und zur Laufzeit einzubinden. Hierdurch entstünde eine weitaus robustere und besser an den Kontext angepasste Architektur, da ungeeignete Dienstgeber dynamisch ausgetauscht werden könnten. Ziel der Arbeit war daher die Schaffung einer semantischen Dienstbeschreibungssprache, die als Grundlage für eine solche Dienstnutzung dienen kann.

Abstract

Ranking - the algorithmic decision on how relevant an information artifact is for a given information need and the sorting of artifacts by their concluded relevancy - is an integral part of every search engine. In this book we investigate how structured Web data can be leveraged for ranking with the goal to improve the effectiveness of search. We propose new solutions for ranking using on-the-fly data integration and experimentally analyze and evaluate them against the latest baselines.

Abstract

For speaking, words in the lexicon are somehow activated from conceptual representations but we know surprisingly little about how this works precisely. Which of the attributes of the concept DOG (e.g. BARKS, IS WALKED WITH A LEASH, CARNIVORE, ANIMATE) have to be activated in a given situation to be able to select the word ‘dog’? Are there things we know about dogs that are always activated for naming and others that are only activated in certain contexts or even never? To date, investigations on lexical access in speaking have largely focused on the effects of distractor nouns on the naming latency of a target noun. We have learned that distractors from the same semantic category (e.g. ‘cat’) hinder naming, but associatively related distractors (‘leash’) may facilitate or hinder naming. However, associatively related words can have all kinds of semantic relationships to a target word, and, with few exceptions, the effects of specific semantic relationships other than membership in the same category as the target concept have not been systematically investigated. This special issue aims at moving forward towards a more detailed account of how precisely conceptual information is used to access the lexicon in speaking and what corresponding format of conceptual representations needs to be assumed.

Abstract

The book researches the use of a semantic wiki in the area of IT Service Management within the IT department of an SME. An emphasis of the book lies in the design and prototypical implementation of tools for the integration of ITSM-relevant information into the semantic wiki, as well as tools for interactions between the wiki and external programs. The result of the book is a platform for agile, semantic wiki-based ITSM for IT administration teams of SMEs.

Abstract

This work introduces Relational Exploration, a method for acquiring complete relational knowledge about a domain of interest by successively consulting a domain expert without ever asking redundant questions. This is achieved by combining Description Logics (DL) and Formal Concept Analysis (FCA): DL formalisms are used for defining FCA attributes while FCA exploration techniques are deployed to obtain or refine DL knowledge specifications.

Abstract

Die Bestimmung der Haltbarkeitsdauer kosmetischer Emulsionen ist von großem industriellen Interesse. Bisherige Verfahren zur Bestimmung der Stabilität von Emulsionen sind nur sehr bedingt auf langzeitstabile Emulsionen anwendbar.In dieser Arbeit wurde erstmals eine optische Zentrifuge zur Vorhersage der Langzeitstabilität von kosmetischen Emulsionen eingesetzt.Diese Methode erfordert keine Wiederholungsmessungen und wurde sowohl auf W/O- als auch auf O/W-Emulsionen angewandt.

Abstract

In der Arbeit wird erstmalig ein Unterstützungssystem für die Geschäftsprozessmodellierung vorgestellt, das dem Benutzer zu seinem gerade editierten Prozess Prozessfragmente aus einer Bibliothek vorschlägt. Der Vorschlag von Prozessfragmenten erfolgt auf Basis von Geschäftsregeln und Korrektheits- und Semantikkriterien. Zusätzlich werden Ähnlichkeitsmaße definiert, durch die Prozessteile mit unterschiedlichem Vokabular zur Beschreibung gleicher Prozessobjekte wieder verwendet werden können.
