11 Overview What is UIMA? Part-of-Speech Tagging With OpenNLP With OpenNLP and UIMA Full Parsing Shallow Parsing More about UIMA
12 What is OpenNLP? A set of NLP tools Open source Java University of Pennsylvania (Tom Morton) English, Spanish, German, Thai What is a toolkit?
13 Annotation Tools OpenNLP sentence detector OpenNLP tokenizer OpenNLP POS tagger OpenNLP chunker OpenNLP parser OpenNLP name finder OpenNLP coreferencer
14 Annotation Models OpenNLP English sentence detector model OpenNLP English tokenizer model OpenNLP English POS tagger model OpenNLP English chunker model OpenNLP English parser models OpenNLP English named entity models OpenNLP English coreferencer models
15 POS Tagging with OpenNLP export OPENNLP_HOME=~gwilcock/Tools/opennlp export CLASSPATH=.:\ $OPENNLP_HOME/lib/opennlp-tools jar:\ $OPENNLP_HOME/lib/maxent jar:\ $OPENNLP_HOME/lib/trove.jar java opennlp.tools.lang.english.sentencedetector \ $OPENNLP_HOME/models/english/sentdetect/EnglishSD.bin.gz java opennlp.tools.lang.english.tokenizer \ $OPENNLP_HOME/models/english/tokenize/EnglishTok.bin.gz java opennlp.tools.lang.english.postagger -d \ $OPENNLP_HOME/models/english/parser/tagdict \ $OPENNLP_HOME/models/english/parser/tag.bin.gz

18 POS Tagging with UIMA Run OpenNLP POS tagger in UIMA Also needs OpenNLP sentence detector and OpenNLP tokenizer Each tool needs a UIMA wrapper These wrappers provided by UIMA Tools run in primitive analysis engines Combined in aggregate analysis engine

33 OpenNLP Chunker Format Token - postag - chunklabel a DT B-NP far RB I-NP more RBR I-NP pleasing JJ I-NP sound NN I-NP.. O
34 Chunking with UIMA Run OpenNLP chunker in UIMA Also needs OpenNLP sentence detector, tokenizer and POS tagger Write a Java wrapper No wrapper provided for chunker Similar to wrapper for POS tagger Add chunker to aggregate analysis engine
35
36 Editing the Type System UIMA type systems Types, subtypes and inheritance Features appropriate for type OpenNLPExampleTypes.xml Edit Token type Has existing postag feature Add new chunklabel feature
37

39 Defining Capabilities Capabilities of each component Specify input and output types Supports interoperability Enables check for correct types Important in pipeline of components

42
43 Colouring the Chunks UIMA Annotation Viewer All Token annotations are same colour Need different colours for NP, VP, PP Write a Chunk Marker annotator Read chunklabel features (B-NP, I-NP) Write new NP, VP, PP annotations NP, VP, PP types already defined for parser
