- Abstract
- Industries have adopted a standardized set of practices for developing their products. In the automotive domain, the provision of safety-compliant systems is guided by ISO 26262, a standard that specifies a set of requirements and recommendations for developing automotive safety-critical systems. For being in compliance with ISO 26262, the safety lifecycle proposed by the standard must be included in the development process of a vehicle. Besides, a safety case that shows that the system is acceptably safe has to be provided. The provision of a safety case implies the execution of a precise documentation process. This process makes sure that the work products are available and traceable. Further, the documentation management is defined in the standard as a mandatory activity and guidelines are proposed/imposed for its elaboration. It would be appropriate to point out that a well-documented safety lifecycle will provide the necessary inputs for the generation of an ISO 26262-compliant safety case. The OSLC (Open Services for Lifecycle Collaboration) standard and the maturing stack of semantic web technologies represent a promising integration platform for enabling semantic interoperability between the tools involved in the safety lifecycle. Tools for requirements, architecture, development management, among others, are expected to interact and shared data with the help of domains specifications created in OSLC. This thesis proposes the creation of an OSLC tool-chain infrastructure for sharing safety-related information, where fragments of safety information can be generated. The steps carried out during the elaboration of this master thesis consist in the identification, representation, and shaping of the RDF resources needed for the creation of a safety case. The focus of the thesis is limited to a tiny portion of the ISO 26262 left-hand side of the V-model, more exactly part 6 clause 8 of the standard: Software unit design and implementation. Regardless of the use of a restricted portion of the standard during the execution of this thesis, the findings can be extended to other parts, and the conclusions can be generalize. This master thesis is considered one of the first steps towards the provision of an OSLC-based and ISO 26262-compliant methodological approach for representing and shaping the work products resulting from the execution of the safety lifecycle, documentation required in the conformation of an ISO-compliant safety case.

- Abstract
- Many real-world domains can be represented as large node-link graphs: backbone Internet routers connect with 70,000 other hosts, mid-sized Web servers handle between 20,000 and 200,000 hyperlinked documents, and dictionaries contain millions of words defined in terms of each other. Computational manipulation of such large graphs is common, but previous tools for graph visualization have been limited to datasets of a few thousand nodes. Visual depictions of graphs and networks are external representations that exploit human visual processing to reduce the cognitive load of many tasks that require understanding of global or local structure. We assert that the two key advantages of computer-based systems for information visualization over traditional paper-based visual exposition are interactivity and scalability. We also argue that designing visualization software by taking the characteristics of a target user's task domain into account leads to systems that are more effective and scale to larger datasets than previous work. This thesis contains a detailed analysis of three specialized systems for the interactive exploration of large graphs, relating the intended tasks to the spatial layout and visual encoding choices. We present two novel algorithms for specialized layout and drawing that use quite different visual metaphors. The H3 system for visualizing the hyperlink structures of web sites scales to datasets of over 100,000 nodes by using a carefully chosen spanning tree as the layout backbone, 3D hyperbolic geometry for a Focus+Context view, and provides a fluid interactive experience through guaranteed frame rate drawing. The Constellation system features a highly specialized 2D layout intended to spatially encode domain-specific information for computational linguists checking the plausibility of a large semantic network created from dictionaries. The Planet Multicast system for displaying the tunnel topology of the Internet's multicast backbone provides a literal 3D geographic layout of arcs on a globe to help MBone maintainers find misconfigured long-distance tunnels. Each of these three systems provides a very different view of the graph structure, and we evaluate their efficacy for the intended task. We generalize these findings in our analysis of the importance of interactivity and specialization for graph visualization systems that are effective and scalable.

- Abstract
- An information system like the Web is a continuously evolving system consisting of multiple heterogeneous information sources, covering a wide domain of discourse, and a huge number of users (human or software) with diverse characteristics and needs, that produce and consume information. The challenge nowadays is to build a scalable information infrastructure enabling the effective, accurate, content based retrieval of information, in a way that adapts to the characteristics and interests of the users. The aim of this work is to propose formally sound methods for building such an information network based on ontologies which are widely used and are easy to grasp by ordinary Web users. The main results of this work are: - A novel scheme for indexing and retrieving objects according to multiple aspects or facets. The proposed scheme is a faceted scheme enriched with a method for specifying the combinations of terms that are valid. We give a model-theoretic interpretation to this model and we provide mechanisms for inferring the valid combinations of terms. This inference service can be exploited for preventing errors during the indexing process, which is very important especially in the case where the indexing is done collaboratively by many users, and for deriving "complete" navigation trees suitable for browsing through the Web. The proposed scheme has several advantages over the hierarchical classification schemes currently employed by Web catalogs, namely, conceptual clarity (it is easier to understand), compactness (it takes less space), and scalability (the update operations can be formulated more easily and be performed more effciently). - A exible and effecient model for building mediators over ontology based information sources. The proposed mediators support several modes of query translation and evaluation which can accommodate various application needs and levels of answer quality. The proposed model can be used for providing users with customized views of Web catalogs. It can also complement the techniques for building mediators over relational sources so as to support approximate translation of partially ordered domain values.

- Abstract
- Das Internet mit seinen ständig neuen Usern und seinem extremen Wachstum bringt viele neue Herausforderungen mit sich. Aufgrund dieses Wachstums bedienen sich die meisten Leute der Hilfe von Suchmaschinen um Inhalte innerhalb des Internet zu finden. Suchmaschinen nutzen für die Beantwortung der User-Anfragen Information Retrieval Techniken. Problematisch ist nur, dass traditionelle Information Retrieval (IR) Systeme für eine relativ kleine und zusammenhängende Sammlung von Dokumenten entwickelt wurden. Das Internet hingegen unterliegt einem ständigen Wachstum, schnellen Änderungsraten und es ist über geographisch verteilte Computer verteilt. Aufgrund dieser Tatsachen müssen die alten Techniken erweitert oder sogar neue IRTechniken entwickelt werden. Eine Suchmaschine die diesen Herausforderungen vergleichsweise erfolgreich entgegnet ist Google. Ziel dieser Arbeit ist es aufzuzeigen, wie Suchmaschinen funktionieren. Der Fokus liegt dabei auf der Suchmaschine Google. Kapitel 2 wird sich zuerst mit dem Aufbau von Suchmaschinen im Allgemeinen beschäftigen, wodurch ein grundlegendes Verständnis für die einzelnen Komponenten geschaffen werden soll. Im zweiten Teil des Kapitels wird darauf aufbauend ein Überblick über die Architektur von Google gegeben. Kapitel 3 und 4 dienen dazu, näher auf die beiden Komponenten Crawler und Indexer einzugehen, bei denen es sich um zentrale Elemente im Rahmen von Suchmaschinen handelt.

- Abstract
- In the Internet information space, advanced information retrieval (IR) methods and automatic text processing are used in conjunction with traditional knowledge organization systems (KOS). New information technology provides a platform for better KOS publishing, exploitation and sharing both for human and machine use. Networked KOS services are now being planned and developed as powerful tools for resource discovery. They will enable automatic contextualisation, interpretation and query matching to different indexing languages. The Semantic Web promises to be an environment in which the quality of semantic relationships in bibliographic classification systems can be fully exploited. Their use in the networked environment is, however, limited by the fact that they are not prepared or made available for advanced machine processing. The UDC was chosen for this research because of its widespread use and its long-term presence in online information retrieval systems. It was also the first system to be used for the automatic classification of Internet resources, and the first to be made available as a classification tool on the Web. The objective of this research is to establish the advantages of using UDC for information retrieval in a networked environment, to highlight the problems of automation and classification exchange, and to offer possible solutions. The first research question was is there enough evidence of the use of classification on the Internet to justify further development with this particular environment in mind? The second question is what are the automation requirements for the full exploitation of UDC and its exchange? The third question is which areas are in need of improvement and what specific recommendations can be made for implementing the UDC in a networked environment? A summary of changes required in the management and development of the UDC to facilitate its full adaptation for future use is drawn from this analysis.

- Abstract
- Diese Diplomarbeit handelt von der Indexierung von unstrukturierten und natürlichsprachigen Dokumenten. Die zunehmende Informationsflut und die Zahl an veröffentlichten wissenschaftlichen Berichten und Büchern machen eine maschinelle inhaltliche Erschließung notwendig. Um die Anforderungen hierfür besser zu verstehen, werden Probleme der natürlichsprachigen schriftlichen Kommunikation untersucht. Die manuellen Techniken der Indexierung und die Dokumentationssprachen werden vorgestellt. Die Indexierung wird thematisch in den Bereich der inhaltlichen Erschließung und des Information Retrieval eingeordnet. Weiterhin werden Vor- und Nachteile von ausgesuchten Algorithmen untersucht und Softwareprodukte im Bereich des Information Retrieval auf ihre Arbeitsweise hin evaluiert. Anhand von Beispiel-Dokumenten werden die Ergebnisse einzelner Verfahren vorgestellt. Mithilfe des Projekts European Migration Network werden Probleme und grundlegende Anforderungen an die Durchführung einer inhaltlichen Erschließung identifiziert und Lösungsmöglichkeiten vorgeschlagen.
