- Abstract
- Klassifikation von bibliografischen Einheiten ist für einen systematischen Zugang zu den Beständen einer Bibliothek und deren Aufstellung unumgänglich. Bislang wurde diese Aufgabe von Fachexperten manuell erledigt, sei es individuell nach einer selbst entwickelten Systematik oder kooperativ nach einer gemeinsamen Systematik. In dieser Arbeit wird ein Verfahren zur Automatisierung des Klassifikationsvorgangs vorgestellt. Dabei kommt das Verfahren des fallbasierten Schließens zum Einsatz, das im Kontext der Forschung zur künstlichen Intelligenz entwickelt wurde. Das Verfahren liefert für jedes Werk, für das bibliografische Daten vorliegen, eine oder mehrere mögliche Klassifikationen. In Experimenten werden die Ergebnisse der automatischen Klassifikation mit der durch Fachexperten verglichen. Diese Experimente belegen die hohe Qualität der automatischen Klassifikation und dass das Verfahren geeignet ist, Fachexperten bei der Klassifikationsarbeit signifikant zu entlasten. Auch die nahezu vollständige Resystematisierung eines Bibliothekskataloges ist - mit gewissen Abstrichen - möglich.

- Abstract
- In most search systems, mapping queries with documents employs techniques such as vector space model, naïve Bayes, Bayesian theorem etc. to classify resulting documents. In this research studies, we are proposing the use of the concept of basic categories to representing the user's level of knowledge based on the concepts he employed during his search activities, so that the system could propose adapted results based on the observed user's level of knowledge. Our hypothesis is that this approach will enhance the decision support system for solving decisional problems in which information retrieval constitutes the backbone technical problem.

- Abstract
- CBR ist eng gekoppelt mit Lernen, verstanden als Anreicherung von Wissen. Wissen wird unterteilt in Faktenwissen und Handhabungs-/Orientierungswissen. Letzteres verfügbar zu haben wird als primäres Ziel von Lernen und damit auch von CBR herausgearbeitet. Die Übertragbarkeitsproblematik, d.h. die Nutzung von gespeichertem Erfahrungswissen (alte Fälle und ihre Lösungen) zur Lösung neuer Problemstellungen wird an einem eingängigen Beispiel (Dunckers Bestrahlungsproblem illustriert). Abschließend wird der CBR-Zyklus kurz vorgestellt

- Abstract
- Mangelndes methodisches Bewußtsein in der Künstlichen Intelligenz hat zur Folge, daß Methoden, die auf einer einzigen zunächst vielversprechenden Idee beruhen, zugunsten anderer fallengelassen werden, sowie sich ernste Schwierigkeiten ergeben. Doch für Methoden gilt nicht das Alles-oder-Nichts-Prinzip; Ziel muß es daher sein, verschiedene sich hinsichtlich ihrer Anwendbarkeit einander ergänzende Methoden aufeinander abzustimmen und zu einem arbeitsfähigen System zu vereinen; das trifft insbesondere auf das bereits vom Ansatz her auf Methodenvielfalt angelegte fallbezogene Schlußfolgern zu. Die von den Kognitionswissenschaften gebotenen Voraussetzungen sind jedoch für solch ein Vorhaben nicht günstig. Es herrscht ein Theorien- und Modellwirrwar, das zu einem Wirrwar von Begriffen, Sichtweisen und Verfahren geführt hat. Die vorliegende Arbeit skizziert einen Ausweg aus dieser unbefriedigenden Situation. Sie orientiert sich an den Fragen 'welche Aufgaben sollen mit fallbezogenem Schlußfolgern gelöst werden?', 'durch welche Merkmale ist dieser Ansatz charakterisiert?' und beschäftigt sich abschließend mit den sich aus den Antworten ergebenden Folgerungen

- Abstract
- Ein wesentlicher Vorteil des CBR im Vergleich zu generativen Ansätzen ist ein geringer Bedarf an das zu formalisierende Wissen. Insbesondere ist es möglich trotz unvollständigen Anpassungswissens vollständige Lösungen zu finden. Dieser Beitrag beschreibt, wodurch sich Anpassungswissen von Regelwissen unterscheidet und wieviel Anpassungswissen man unbedingt benötigt. Die Leistungsfähigkeit eines wissensarmen CBR-Ansatzes wird am Beispiel der Anpassung toplogischer Strukturen diskutiert

- Abstract
- This article reports on a longitudinal analysis of query logs of a web-based case library system during an 8-year period (from 2005 to 2012). The analysis studies 3 different information-seeking approaches: keyword searching, browsing, and case-based reasoning (CBR) searching provided by the system by examining the query logs that stretch over 8 years. The longitudinal dimension of this study offers unique possibilities to see how users used the 3 different approaches over time. Various user information-seeking patterns and trends are identified through the query usage pattern analysis and session analysis. The study identified different user groups and found that a majority of the users tend to stick to their favorite information-seeking approach to meet their immediate information needs and do not seem to care whether alternative search options will offer greater benefits. The study also found that return users used CBR searching much more frequently than 1-time users and tend to use more query terms to look for information than 1-time users.

- Abstract
- This paper reportes a study that investigated the effects of conceptual description and search practice on users' mental models and information seeking in a case-based reasoning retrieval (CBR) system with a best match search mechanism. This study also found examined how the presence of a mental model affects the users' search performance and satisfaction in this system. The results of this study revealed that the conceptual description and search practice treatments do not have significantly different effects on the types of user's mental models, search correctness, and search satisfaction. However, the search practice group spent significantly less time than the conceptual description group in finding the results. Qualitative analysis for the subjects' post mental models revealed that subjects in the conceptual description group seem to have more complete mental models of the best match system than those in the search practice group. This study also that subjects with the best match mental models have significantly higher search correctness and search result satisfaction than subjects without the best match mental models. However, the best match mental models do not guarantee less search time in finding the results. This study did not find a significant correlation among search time, search correctness and search satisfaction. The study concludes with suggestions for future research and implications for system developers who are interested in CBR retrieval systems.

- Abstract
- Discusses a hybrid approach combining case-based reasoning and information retrieval for the retrieval of full text documents. It takes as input a standard symbolic representation of a problem case and retrieves text of relevant cases from a document collection dramatically larger than the case base available to the CBR system. It works by performing a standard HYPO style analysis and uses the texts associated with important classes of cases found in this analysis to seed a modified version of INQUERY's relevance feedback mechanism in order to generate a query composed of individual terms or pairs of terms. It exteds the reach of CBR to much larger corpora, and it anbales the injection of knowledge based techniques into traditional IR. Describes the CBR-IR approach and reports on-going experiments
