Chemnitz at the CHiC Evaluation Lab 2012: Creating an Xtrieval Module for Semantic Enrichment

Cultural heritage is one of the most valuable resources that describe the creative power of mankind. In this article we describe a total number of 96 experiments that have been submitted as contributions to the three subtasks of the Cultural Heritage in CLEF pilot evaluation lab. At the core of the majority of these experiments lies a prototype implementation for semantic enrichment based on DBpedia. The evaluation of the experiments demonstrate that semantic enrichment does not improve retrieval effectiveness in comparison to straightforward baseline experiments. The results also indicate that automatic query expansion does not improve retrieval performance for the pilot lab test collection. Further experiments are needed in order to be able to draw conclusions on whether semantic enrichment can improve retrieval results on cultural heritage collections or not.
