The use of whitespace (newlines) always bothered me a little. So I improved it from my point-of-view. The new output groups a dataset and its TriplesMaps together and leaving whitespace between two datasets. Additionally, I added the message for finishing a dataset and the end of the semantification of that dataset. In the original output, the very last message was that the last dataset (referred to by its name) was successfully semantified, I changed that to 'all datasets'. Furthermore, I added the execution time again. But feel free to remove it if you prefer to only keep it in the statistics file.
