kandi X-RAY | jcrfsuite Summary

jcrfsuite is a Java library typically used in Artificial Intelligence, Natural Language Processing applications. jcrfsuite has no bugs, it has no vulnerabilities, it has build file available and it has low support. However jcrfsuite has a Non-SPDX License. You can download it from GitHub, Maven.

This is a Java interface for crfsuite, a fast implementation of Conditional Random Fields, using SWIG and class injection technique (the same technique used in snappy-java). Jcrfsuite provides API for loading trained model into memory and do sequential tagging in memory. Model training is done via command line interface. The library is designed for building Java applications for fast text sequential tagging such as Part-Of-Speech (POS) tagging, phrase chunking, Named-Entity Recognition (NER), etc. Jcrfsuite can be dropped into any Java web applications and run without problem with JVM's class loader.

jcrfsuite training file format

QUESTION

jcrfsuite training file format

Asked 2018-Nov-07 at 00:49

From what I understand from the example of POS Tagging given in the examples of jcrfsuite. The training file is tab separated and first token is the label. But I do not get the BigCluster| thing. Can somebody help me with how to specify tokens in training file.

Example below:

O BigCluster|00 BigCluster|0000 BigCluster|000000 BigCluster|00000000 BigCluster|0000000000 BigCluster|000000000000 BigCluster|00000000000000 BigCluster|0000000000000000 NextBigCluster|0100 NextBigCluster|01000101 NextBigCluster|010001011111 POSTagDict|D POSTagDict|N POSTagDict|^ POSTagDict|$ POSTagDict|G NextPOSTag|V 1gramSuff|i 1gramPref|i prevword| prevcurr||i nextword|predict nextword|predict currnext|i|predict Word|I Lower|i Xxdshape|X charclass|1, first-shortcap prevnext||predict t=0

Test file format:

! BigCluster|01 BigCluster|0110 BigCluster|011011 BigCluster|01101100 BigCluster|0110110011 BigCluster|011011001100 BigCluster|01101100110000 BigCluster|0110110011000000 NextBigCluster|1000 NextBigCluster|10001000 NextBigCluster|100010000000 POSTagDict|V NextPOSTag|, metaph_POSDict|N 1gramSuff|n 2gramSuff|nn 3gramSuff|mnn 4gramSuff|mmnn 5gramSuff|mmmnn 6gramSuff|ammmnn 7gramSuff|aammmnn 8gramSuff|aaammmnn 9gramSuff|daaammmnn 1gramPref|d 2gramPref|da 3gramPref|daa 4gramPref|daaa 5gramPref|daaam 6gramPref|daaamm 7gramPref|daaammm 8gramPref|daaammmn 9gramPref|daaammmnn prevword| prevcurr||daaammmnn nextword|. nextword|. currnext|daaammmnn|.

What is specified after the label is a list of feature-name and feature-value. It is in a sparse representation instead of tabular representation.

BigCluster is just one of the features and it's relevant to the specific example only. You should create your own features if you are training from scratch.
