Regular Expression "not matching" and SPARQL Filter function usage

OK, I had a problem here when converting bio2rdf.org irefindex data to nanopublication using SPARQL here:

In a database, if the item is looking for have multiple types, but you have only need one of those types in your converted Data, what are can do-is-use-a SPARQL filter function with regex

1. The proper SPARQL filter syntax is as follows:

Selectwhere{  ? s? P O.    for filter) #it ' s brackets () not curly parenthesis {}}

2. The proper regex to match those items if you don ' t want

^. *? (? < ! Resource) $ # The Regex filter regex (? Interaction_type, "^. *? (? <  Use  in the filter

^.*? (?<
2. For example, find a string that does not end in COM.
   www.sina.com.cn
   www.educ.org
   www.hao.cc
   Www.baidu.com
   
   ^.*? (? <!com) $ matches the first 3 rows of results. If you look for a string that ends in COM, use regular ^.*? (? <=com) $ or ^.*?com$


Online regex tester is also very helpful when debugging your regex:https://regex101.com/
