abstract = {The enterprise information space is split in two hemispheres. Documents contain
unstructured or semistructured information; structured information is stored in
databases. As regards the content, both kinds of information are complementary
parts. However, enterprise information systems usually focus on one part, only.
Our approach improves document retrieval in the intranet by exploiting the
enterprise's databases. In particular, we exploit database information to
describe the context of documents and exploit this context to enhance common
full text search. In this paper, we show how to model and compute document
context and present results on runtime performance},

abstract = {More and more spatial data is accessible over the web or through portals of
wireless service providers. In this context the main selection criteria for the
data are the type of the requested data objects and their position in the real
world. Integration and performance issues are challenged by the need to process
ad hoc queries in an interactive fashion. In this paper we investigate how a
main memory query engine can be used to meet these requirements. It has the
added benefit of being easily deployable to many components in a large-scale
data integration system. Hence, we analyze how such a query engine can best
exploit the query characteristics by employing an index structure that
leverages spatial and type dimensions.
In order to support query processing in the best possible way we investigate a
specific multi-dimensional main memory index structure. Compared to the
straightforward approach using separate indexes on type and position we can
increase the performance up to almost an order of magnitude in several
important usage scenarios. This requires to tweak the mapping of type IDs to
values in the type dimension, which we discuss extensively. This enables the
overall system to be used interactively, even with large data sets.},

abstract = {Relational division, also known as small divide, is a derived operator of the
relational algebra that realizes a many-to-one set containment test, where a
set is represented as a group of tuples: Small divide discovers which sets in a
dividend relation contain all elements of the set stored in a divisor relation.
The great divide operator extends small divide by realizing many-to-many set
containment tests. It is also similar to the set containment join operator for
schemas that are not in first normal form.
Neither small nor great divide has been implemented in commercial relational
database systems although the operators solve important problems and many
efficient algorithms for them exist. We present algebraic laws that allow
rewriting expressions containing small or great divide, illustrate their
importance for query optimization, and discuss the use of great divide for
frequent itemset discovery, an important data mining primitive.
A recent theoretic result shows that small divide must be implemented by
special purpose algorithms and not be simulated by pure relational algebra
expressions to achieve efficiency. Consequently, an efficient implementation
requires that the optimizer treats small divide as a first-class operator and
possesses powerful algebraic laws for query rewriting.},

requiring the original data during the analysis phase, and (2) a standard

development and reuse of tools for analysis and exploration of itemset-based
patterns. Instead of storing the original datasets, our approach organizes
frequent itemsets holding on different partitions of the original transactions
in a data warehouse that retains sufficient information for future analysis. A
running example for mining calendar-based patterns on data streams is
presented. Staging area tasks are discussed and standard conceptual and logical
schemas are presented. Properties of this standard modeling allow to retrieve
frequent itemsets holding on any set of partitions along with upper and lower
bounds on their frequency counts. Furthermore, precision guarantees for some
interestingness measures of association rules are provided as well.},

Anwendungstechnologien aufgezeigt, die die nachhaltige Gestaltung von
Innovationsprozessen unterst{\"u}tzen k{\"o}nnen. Die einleitenden Kapitel stellen
sowohl den Innovationsprozess und grunds{\"a}tzliche Themenfelder, die im
Forschungsprojekt nova-net bearbeitet werden, dar als auch das so genannte
Information Workflow, das den Informationsverarbeitungsprozess in sinnvolle
Phasen unterteilt und die systematische L{\"o}sung von Innovationsproblemen

Innovationsmanagement relevante Technologien den einzelnen
Informationsverarbeitungsphasen zu, und widmen sich speziellen Problemen, die
in den Themenfeldern des Forschungsprojekts nova-net besondere Beachtung
verdienen.},
