Knowledge mining over scientific literature and technical documentation

Abstract This dissertation focuses on the extraction of information implicitly encoded in domain descriptions (technical terminology and related items) and its usage within a restricted-domain question answering system (QA). Since different variants of the same term can be used to refer to the same domain entity, it is necessary to recognize all possible forms of a given term and structure them, so that they can be used in the question answering process. The knowledge about domain descriptions and their mutual relations is leveraged in an extension to an existing QA system, aimed at the technical maintenance manual of a well-known commercial aircraft. The original version of the QA system did not make use of domain descriptions, which are the novelty introduced by the present work. The explicit treatment of domain descriptions provided considerable gains in terms of efficiency, in particular in the process of analysis of the background document collection. Similar techniques were later applied to another domain (biomedical scientific literature), focusing in particular on protein- protein interactions. This dissertation describes in particular: (1) the extraction of domain specific lexical items which refer to entities of the domain; (2) the detection of relationships (like synonymy and hyponymy) among such items, and their organization into a conceptual structure; (3) their usage within a domain restricted question answering system, in order to facilitate the correct identification of relevant answers to a query; (4) the adaptation of the system to another domain, and extension of the basic hypothesis to tasks other than question answering. Zusammenfassung Das Thema dieser Dissertation ist die Extraktion von Information, welche implizit in technischen Terminologien und ähnlichen Ressourcen enthalten ist, sowie ihre Anwendung in einem Antwortextraktionssystem (AE). Da verschiedene Varianten desselben Terms verwendet werden können, um auf den gleichen Begriff zu verweisen, ist die Erkennung und Strukturierung aller möglichen Formen Voraussetzung für den Einsatz in einem AE-System. Die Kenntnisse über Terme und deren Relationen werden in einem AE System angewandt, welches auf dem Wartungshandbuch eines bekannten Verkehrsflugzeug fokussiert. Die ursprüngliche Version des Systems hatte keine explizite Behandlung von Terminologie. Die explizite Behandlung von Terminologie lieferte eine beachtliche Verbesserung der Effizienz des Systems, insbesondere was die Analyse der zugrundeliegenden Dokumentensammlung betrifft. Ähnliche Methodologien wurden später auf einer anderen Domäne angewandt (biomedizinische Literatur), mit einen besonderen Fokus auf Interaktionen zwischen Proteinen. Diese Dissertation beschreibt insbesondere: (1) die Extraktion der Terminologie (2) die Identifikation der Relationen zwischen Termen (wie z.B. Synonymie und Hyponymie) (3) deren Verwendung in einen AE System (4) die Portierung des Systems auf eine andere Domäne

Cyber security information sharing in the United States : an empirical study including risk management and control implications, 2000-2003

A tremendous amount of change in traditional business paradigms has occurred over the past decade through the development of Electronic Commerce and ad\ ancements in the field of Information Technology. As lesser-developed countries progress and become more prosperous. traditional . first world' countries have migrated to become strong service oriented economies (Asch, 200 I). Supporting technologies have developed over the past decade which has exploited the benefits of the Internet and other infonnation technologies. While Electronic Commerce continues to grow there is a corresponding impact on computer software and individual privacy (Ghosh and Swaminatha, 200 I). Recently. the U.S. National Institute of Standards and Technology (NIST) found that software bugs cost the U.S. economy approximately $59.5 billion, or .600/0 of the annual Gross Domestic Product (U.S. Department of Commerce, 2003). In addition, we have witnessed a rise in the strength and impact of Denial of Service and other types of computer attacks such as: viruses. trojans. exploit scripts and probes/scans. Popular industry surveys such as the annual Federal Bureau of Investigation/Computer Security Institute (Gordon. Et. AI.. 2006) confirm the growing threats in the Information Assurance field. In addition to these concerns our increased reliance on the Internet enabled systems (loudon and loudon. 2000). E-Commerce systems and Information Technologies an integrated suite of risks which must be managed effectively across the public and private sectors (Backhouse. Et. AI. 2005. Ghosh and Swamintha. 200 I. Parker. 200 I. Graf. 1995. Greenberg and Goldman, 1995). Previous research (Rumizen, 1998. Haver, 1998, Roulier, 1998) examined InterOrganisational, Web Infonnation Systems and Government Information Systems in order to assess how companies and other organisations can effectively design these information systems such that maximum benefits can be achieved for all participating organisations. Furthermore, Davenport, Harris and Delong (2001) and Davenport (1999) explained that collaboration is central to the results of a knowledge management system in which open, nonpolitical, non-competitive entities are involved in environments to achieve optimal individual and collective results. Before this memorable event. some related programmatic initiatives were already in-process at that time. The United States government built upon its active leadership in the areas of computer security and information assurance when it launched a number of important efforts to manage information security threats. This was clearly evident when President Clinton made the U.S. National Infrastructure (Nil) a major national priority in the 1 990s. One critical development occurred in 1998 when the National Infrastructure Protection Centre was established to be the central point for gathering, analysing and disseminating critical cyber security information and built upon the previous success of the national Computer Emergency Response Team (CERT). Earlier research (Rich. 2001, Soo Hoo, 2000. Howard. 1997 and Landwher, 1994) addressed various aspects of information security information and incident reporting. Also. Vatis 0001) addressed some research considerations in this area while investigating foreign network centric and traditional warfare events primarily through Denial of Service and Web Site Defacement attacks. However. areas for new exploration existed especially as they related to U.S. critical infrastructure protection (Karestand. 2003. Vatis. 200 I. U.S. General Accounting Office. 2000. Alexander and Swetham. 19(9). Finally. Information and Network Centric Warfare (Arens and Rosenbloom. 2003. Davies. 2000. Denning and Baugh. 2000. and Schwartau. 1997) are increasing national security issues in the \\' ar on Terrorism and Homeland Security in general
