Incomplete data accompanies our life processes and covers almost all fields of scientific
studies, as a result of delivery failure, no power of battery, accidental loss, etc. However, how …

Risk, Reliability and Safety contains papers describing innovations in theory and practice

We study models of incomplete information for XML, their computational properties, and
query answering. While our approach is motivated by the study of relational incompleteness …

The notion of certain answers arises when one queries incompletely specified databases,
eg, in data integration and exchange scenarios, or databases with missing information …

Both feature and class modeling are used in Software Product Line (SPL) engineering to
model variability. Feature models are used primarily to represent user-visible characteristics …

The traditional notion of instantiation in Object-Oriented Modeling (OOM) requires objects to
be complete, ie, be fully certain about their existence and attributes. This paper explores the …

This chapter deals with data mining in uncertain XML data models, whose uncertainty
typically comes from imprecise automatic processes. We first review the literature on …

In XML data exchange, a schema mapping specifies rules for restructuring a source
document under the target schema, and queries over the target document must be …

Keyword search is the most popular technique of searching information from XML
(eXtensible markup language) document. It enables users to easily access XML data without …

We consider incomplete specifications of XML documents in the presence of schema
information and integrity constraints. We show that integrity constraints such as keys and …
