  • Steps to compile and run jar

  • System requirements

    • Install Java JDK
    • Add jdk\bin to Windows PATH
  • Compile source files to generate opennlp-parser-svo-new.jar

javac -cp opennlp-tools-1.6.0.jar ParseKnowledgeNpVisited.java ParseKnowledgeNpVisitedMap.java -d .
jar cvf opennlp-parser-svo-new.jar ./opennlp
java -cp opennlp-tools-1.6.0.jar opennlp.tools.cmdline.CLI Parser en-parser-chunking.bin < input.txt > output-parser.txt
  • SVO Triples are extracted using the command
    • Unix shell uses colon (:) as the path separator
java -cp opennlp-parser-svo-new.jar;opennlp-tools-1.6.0.jar opennlp.tools.parser.ParseKnowledgeNpVisitedMap -fun -pos head_rules < ie-parser.txt
  • Expected output
Google is located in Mountain view
0       "Google"        "is located"    "in Mountain view"
Mountain view is in California
1       "Mountain view" "is"    "in California"
Google will acquire YouTube , announced the New York Times .
2       "Google"        "will acquire"  "YouTube"
2       "Google"        "announced"     "the New York Times"
Google and Apple are headquartered in California .
3       "Google and Apple"      "are headquartered"     "in California"
  • Alternate code command
java -cp opennlp-parser-svo-new.jar;opennlp-tools-1.6.0.jar opennlp.tools.parser.ParseKnowledgeNpVisited -fun -pos head_rules < ie-parser.txt
