Inhalt

Aufgrund der Ausbreitung des Internets werden immer gr??ere Datenmengen erzeugt und gespeichert, die nicht strukturiert und statisch sondern heterogen und dynamisch sind. Das Problem, interessante und relevante Daten und Zusammenh?nge aus diesen Datenmengen zu gewinnen wird durch die Masse an Daten und der Heterogenit?t in der Struktur zu einer immer gr??eren Herausforderung f?r Unternehmen, Organisationen und Einzelpersonen.
Thema dieses Seminars sind Methoden zur L?sung dieses Problems aus verschiedenen Disziplinen wie Data Mining, Maschinellem Lernen, Business Intelligenz und Semantic Web.
Betrachtet wird dabei die Repr?sentation von Daten wie z.B. relationale Datenbanken, XML, RDF und Ontologien sowie die Inferenz- und Deduktionsmechanismen, die auf diesen Daten arbeiten und Informationen und Zusammenh?nge ableiten. Beispiele f?r solche Mechanismen sind Klassifikationsalgorithmen und Web-Suche.

Summary

Due to the usage of the Internet huge amounts of data are produced and stored which are not structured and static but rather heterogenous and dynamic. The problem of extracting relevant data and interrelations from those amounts of data becomes more and more challenging for companies, organizations and individuals due to the large amount and the heterogenity in structure.
This seminar covers possible solutions to this problem from different disciplines like data mining, machine learning, business intelligence and the semantic web.
We will examine the representation of data like, e.g., relational databases, XML, RDF and ontologies as well as inference and reasoning mechanims operating on the data with the goal of deducting information and interrelations. Examples for such mechanisms are classification algorithms and web search.
