Handling uncertainty in information extraction

Publikováno v: URSW 2011. :109-112

This position paper proposes an interactive approach for developing information extractors based on the ontology definition process with knowledge about possible (in)correctness of annotations. We discuss the problem of managing and manipulating prob

Onzekere databases

Publikováno v: Database magazine. 21(4):22-27

Een recente ontwikkeling in het databaseonderzoek betret zogenaamde 'onzekere databases'. Dit artikel beschrijft wat onzekere databases zijn, hoe ze gebruikt kunnen worden en welke toepassingen met name voordeel zouden kunnen hebben van deze technolo

Data exchange between embedded systems and other small or large computing devices increases. Since data in different data sources may refer to the same real world objects, data cannot simply be merged. Furthermore, in many situations, conflicts in da

This work explores the feasibility of storing and querying probabilistic XML in a probabilistic relational database. Our approach is to adapt known techniques for mapping XML to relational data such that the possible worlds are preserved. We show tha

Indeterministic Handling of Uncertain Decisions in Duplicate Detection

Autor: Panse, Fabian, van Keulen, Maurice, Ritter, Norbert

In current research, duplicate detection is usually considered as a deterministic approach in which tuples are either declared as duplicates or not. However, most often it is not completely clear whether two tuples represent the same real-world entit
