A Relational Operator Approach to Data Fusion
- …Integrated information systems provide users with a single unified view to heterogeneous data sources. As the resolution of schema level conflicts and the detection of fuzzy duplicates has been looked at more comprehensively, the problem of resolving data level conflicts still remains. We prop…

Conflict Handling Strategies in an Integrated Information System
- …Integrated information systems provide users and applications with a unified view of heterogeneous data sources. To provide a single consistent result for every object represented in these data sources, data fusion is concerned with resolving data inconsistencies within and among the sources. We pre…

M.: Data Fusion in Three Steps: Resolving Inconsistencies at Schema-, Tuple-, and Value-level
- …Heterogeneous and dirty data is abundant. It is stored under different, often opaque schemata, it represents identical real-world objects multiple times, causing duplicates, and it has missing values and conflicting values. Without suitable techniques for integrating and fusing such data, the data q…

Query planning in the presence of overlapping sources
- …Abstract. Navigational queries on Web-accessible life science sources pose unique query optimization challenges. The objects in these sources are interconnected to objects in other sources, forming a large and complex graph, and there is an overlap of objects in the sources. Answering a query requir…

Querying Web-Accessible Life Science Sources:
- …Introduction by a complex graph of overlapping sources, and multiple alternate links between sources. A (navigational) query may be answered by traversing multiple alternate paths between a start source and a target source. Each of these paths may have dissimilar benefit, e.g., the cardinality of r…
