GridVine: an Infrastructure for Peer Information Management

GridVine is a semantic overlay infrastructure based on a peer-to-peer (P2P) access structure. Built following the principle of data independence, it separates a logical layer — in which data, schemas, and schema mappings are managed — from a physical layer ...

Semantic validation in spatio-temporal schema integration

Anastasiya Sotnykova

This thesis proposes to address the well-know database integration problem with a new method that combines functionality from database conceptual modeling techniques with functionality from logic-based reasoners. We elaborate on a hybrid - modeling+validat ...

Similarity Queries on Structured Data in Structured Overlays

Manfred Hauswirth, Roman Schmidt

Structured P2P systems based on distributed hash tables are a popular choice for building large-scaled data management systems. Generally, they only support exact match queries, but data heterogeneities often demand for more complex query types, particular ...

Belief Propagation on Uncertain Schema Mappings in Peer Data Management Systems

Karl Aberer, Philippe Cudré-Mauroux

Until recently, most data integration techniques involved central components, e.g., global schemas, to enable transparent access to heterogeneous databases. Today, however, with the democratization of tools facilitating knowledge elicitation in machine-pro ...

Predictive Approach for Database Schema Evolution

Hassina Bounif

Information systems, including their core databases need to meet changing user requirements and adhere to evolving business strategies. Traditional database evolution techniques focus on reacting to change to smoothly perform schema evolution operations an ...

Analyzing Semantic Interoperability in Bioinformatic Database Networks

Karl Aberer, Philippe Cudré-Mauroux, Adriana Budura, Julien Gaugaz

We consider the problem of analytically evaluating semantic interoperability in large-scale networks of schemas interconnected through pairwise schema mappings. Our heuristics are based on a graph-theoretic framework capturing important statistical propert ...

Schema matching for structured document transformations

Aïda Boukottaya

This dissertation studies structured document content reuse problem. In structured document content reuse, a document (or a part of document) structured under one schema must be restructured and translated into an instance of a different schema. Thus, a no ...

Indexing and selection of data items in huge data sets by constructing and accessing tag collections

Roger Hersch, Sébastien Ponce

We present here a new way of indexing and retrieving data in huge datasets having a high dimensionality. The proposed method speeds up the selecting process by replacing scans of the whole data by scans of matching data. It makes use of two levels of catal ...
