Since the latest changes including the enhancer chains and the language sensitivity of the ner / linking engines, the simple text example "John Smith was born in London." does not work anymore.
I guess, this is because now the langid engine is set as required engine and the language dedected is "FI" and therefore, the engines do not produce any results.
I see several options to overcome this:
1. change the example text to a correctly dedected sentence such as the one used in the tests: "The Stanbol enhancer can detect famous cities such as Paris and people such as Bob Marley."
2. change the behaviour of langID to skip such short sentences, where it is difficult to detect the language
There maybe additonal or better options.
