I am a PhD candidate at the Chair of Information Systems V: Web-based Systems, supervised by Prof. Dr. Christian Bizer, working on the expansion of cross-domain knowledge base using structured web data. In my research I focus on the tasks of Long-Tail Entity Extraction and Time-Dependent Data Fusion to augment knowledge bases like DBpedia or Wikidata using web table corpora provided by the Web Data Commons Project.
Time-Dependent Ground-Truth Dataset
Ground truth of time-dependet data from various domains. The datset allows the development and evaluation of methods dealing with time-dependent data.
Web Tables for Long-Tail Entity Extraction
Gold standard for evaluating the extraction of long-tail entities from web tables. The dataset was built with the motivation of augmenting a cross-domain knowledge base with previously unknown entities from web data.
Extracting Long Tail Entities from Web Tables for Augmenting Cross-Domain Knowledge Bases
Code und instructions on replicating our research on the extraction of long-tail entities from web tables and the use of weak supervision approaches for this task.
