Kurzfassung englisch:
The usefulness and ease of use of dashboards are
essential elements in supporting interactive queries in data warehousing
systems, as they provide the analysts the view of critical
business metrics that reflect the business performance. However,
on-demand dashboard development presents a challenging task
for linking semantic equivalent data facts, discovering structural
dependencies between and within data sources. In this paper,
we introduce an improved approach for dashboard development
that is supported by by-example framework and semantic-based
data linkage management. In this Dashboard-by-example (DBE)
framework, hypergraph-based techniques are adopted to acquire
knowledge from heterogeneous and disparate data into homogeneous
ontological clusters and partitions. Moreover, the use of
hypergraph-guided data linkage provides multiple perspectives
on the knowledge space, supporting interaction model to explore,
contextualize and aggregate the data depending on the application
needs. The applicability of our approach is discussed in a case
study scenario, highlight the flexibility and efficiency in handling
on-demand requirements in data warehousing systems.
