Learn More about Your Data: A Symbolic Regression Knowledge Representation Framework  [PDF]
Ingo Schwab, Norbert Link
International Journal of Intelligence Science (IJIS) , 2012, DOI: 10.4236/ijis.2012.224018
Abstract: In this paper, we propose a flexible knowledge representation framework which utilizes Symbolic Regression to learn and mathematical expressions to represent the knowledge to be captured from data. In this approach, learning algorithms are used to generate new insights which can be added to domain knowledge bases supporting again symbolic regression. This is used for the generalization of the well-known regression analysis to fulfill supervised classification. The approach aims to produce a learning model which best separates the class members of a labeled training set. The class boundaries are given by a separation surface which is represented by the level set of a model function. The separation boundary is defined by the respective equation. In our symbolic approach, the learned knowledge model is represented by mathematical formulas and it is composed of an optimum set of expressions of a given superset. We show that this property gives human experts options to gain additional insights into the application domain. Furthermore, the representation in terms of mathematical formulas (e.g., the analytical model and its first and second derivative) adds additional value to the classifier and enables to answer questions, which sub-symbolic classifier approaches cannot. The symbolic representation of the models enables an interpretation by human experts. Existing and previously known expert knowledge can be added to the developed knowledge representation framework or it can be used as constraints. Additionally, the knowledge acquisition framework can be repeated several times. In each step, new insights from the search process can be added to the knowledge base to improve the overall performance of the proposed learning algorithms.

Transatlantic communication in the 19th century aspects of the correspondence between alexander von humboldt and george ticknor
Schwarz, Ingo
Asclepio : Revista de Historia de la Medicina y de la Ciencia , 2004,
Abstract: The Prussian explorer Alexander von Humboldt (1769-1859) and the North American scholar George Ticknor (1791-1871) met in 1817 in Paris, after Ticknor had studied languages, history, and natural sciences at the University of G ttingen. Two years later, he became the first Harvard Professor of the French and Spanish Languages and Literatures. When Ticknor visited Europe in 1836 and 1856, Humboldt was his guide in the Prussian Capital. Both, Humboldt and Ticknor were mediators between the Old World and the New Continent at a time when nationalism was fashionable both in literature and in politics. Humboldt and Ticknor did not agree on all political questions. However, their respect for each other helped them avoid controversial topics in their correspondence, and possibly in their conversations. With their ability to rank the things they had in common higher than their differences they were able to maintain a fruitful transatlantic dialogue over forty years.

Humboldt y Ticknor fueron mediadores entre el Viejo Mundo y el Nuevo Continente en una época en que el nacionalismo estaba de moda en la literatura y la política. Humboldt y Ticknor no estaban de acuerdo en todas las cuestiones políticas. Sin embargo, el respecto que existía entre ellos evitó los asuntos controvertibles en su conversación y posiblemente en su correspondencia. Con su habilidad para clasificar las cosas tenían en común por encima de sus diferencias ser capaces de mantener un diálogo fructífero trasatlántico durante cuarenta a os.
Web 2.0 aus Nutzer- und Bibliothekssicht: Vorrang für Kernaufgaben der Bibliothek
Ingo Caesar
Libreas : Library Ideas , 2007,
Abstract: Library 2.0 has become a buzzword in the community of librarians. It seems that increasing political participation is more achievable now than ever. But long lasting processes of institution building of libraries have brought us to the point that it is not useful to negotiate the core tasks of librarianship in the arena of web 2.0 communities. Even though these tasks are dynamically and discussable, libraries have the responsibility to act as culture building, independent authorities with no-go-areas. Anyway, there are different virtual services within the applications of web 2.0 software that are useful for a better support of the customers’ needs in using the library. I present examples and scenarios for mash-ups, forums, voting systems and some other tools and their potential. Finally, it is necessary to ask in how far these tools optimize the contact with the library user. Some basic problems like decreasing resources or the enlargement of catalogues and library networks are more important to solve than just to focus on social software.

Quality of life before and after septoplasty and rhinoplasty
Baumann, Ingo
GMS Current Topics in Otorhinolaryngology, Head and Neck Surgery , 2010,
Abstract: Subjective assessment of quality of life (QOL) as an important aspect of outcomes research has received increasing importance during the past decades. QOL is measured with standardized questionnaires which had been tested with regard to reliability, validity, and sensitivity. Surgical procedures of the nasal septum (septoplasty) and the external nose (rhinoplasty) are frequently performed. Since many years subjectively assessed results of these operations have been reported in the literature. However, validated QOL instruments were applied only for one decade. Beforehand, measurements were performed using retrospective assessment of satisfaction or visual analogue scales. Prospective application of validated disease-specific and general measuring instruments has to be demanded for future studies. Most of the septoplasty patients as well as most of the rhinoplasty patients evaluate the operation being successful. However, a relevant number of patients is not satisfied with the result of surgery. In this context, QOL instruments have the potential to identify further factors influencing the outcome. Especially in rhinoplasty patients, special attention has to be drawn on potential psychosocial effects of the operation.

A Ride Through the new age of Librarianship: Various Questions and Only a few Answers.Experiences From the BOBCATSSS 2008 Symposium in Zadar
Ingo Caesar
Libreas : Library Ideas , 2008,
Abstract: Since BOBCATSSS-Symposia usually have an open minded atmosphere, they present a very good opportunity for an open and undogmatic discussion about the challenges of librarianship and information science. This article deals with experiences I made when I visited several workshops and panels dealing with the topics “Information Literacy in the Digital Age” and “Web 2.0 Applications for Libraries”. In my personal view the participants are still in the stadium of getting aware of the challenges arising from these topics. Secondly, I want to depict the openness of the "BOBCATSSS Discourse Style" that I experienced while I was listening to the discussions.

Abstract: A presente reflex o procura instalar algumas indaga es sobre os efeitos da media o do discurso, especialmente quando se opera com as referências contraditórias natural versus social para orientar a compreens o dos processos de (des)humaniza o do mundo dos homens. A orienta o teórica se faz, num primeiro plano, baseada em Bakhtin, especificamente quanto à concep o de discurso como reflexo e refra o social e como processo dialógico e polif nico. Para a abordagem da temática sobre os sentidos possíveis de “vida humana”, as contribui es de Lukács e Heller possibilitam encaminhar, embora restrita ao espa o do artigo, uma reflex o sobre os efeitos dos equívocos conceituais e operacionais e a importancia do discurso para a suas supera es.
Zur Rechtsgeschichte der Wasserverwaltung in Iberoamerika - Das Beispiel Chile

Forum Historiae Iuris , 2001,
Abstract: Ingo Gentes - Abstract The history of water law and water administration in the New World is based on roman and more especially on iberian law experiences, so are the fueros or the siete partidas. The development of water law in the hispanic world during the colony age -especially appointed in the summary of the supreme indian law from 1681- inhered the creation of a new juridical tendency with the so-called mercy of water rights (merced de aguas) which were given by the crown to private men. With the begin of chilean republic age until the codification of national chilean water law (1951, 1969 and 1981) the influnce of these water using rights (derecho de aprovechamiento) changed according to the different political sceneries (liberalism, socialism, neoliberalism). Actually there is a debate in modifying the water rigths due to a variety of conflicts, principally caused by the private use of a scarce ressource.
