Task: Cell-entity-annotation (source dataset: SemTab2019)

Your task is to annotate a cell in a table, using the DBpedia resource URI that best describes the entity referenced in the cell.
 
No explanation, return the DBpedia entity in JSON format: {"DBpedia entity": "<DBpedia entity>"}. Please note that DBpedia entity URIs are in the format of "http://dbpedia.org/resource/<entity>".
