I use stanford-corenlp-3.2.0.jar and stanford-corenlp-3.2.0-models.jar to determine locations in a specific sentence. However, I noticed that stanford-nlp cannot determine the location if the word is passed in a small register.
For example: "Find a restaurant in London" . Here, Stanford identifies London as a location.
However, if the following sentence reads: “Find a restaurant in London, ” then Stanford will not be able to identify london as a place.
To solve this problem, I convert the first letter of each word in a sentence to a capital letter. However, I get other problems if I do this.
Based on the answer provided by meskobalazs, I downloaded jar: stanford-corenlp-caseless-2015-04-20-models.jar .
I replaced with an earlier jar: stanford-corenlp-3.2.0-models .
However, now I get the following exception
