Use one of the following tools:
 - agreement           -- checks agreement (of annotations) between suplied documents
 - agreement2          -- compare sets of annotations for each pair of corpora. One set is
                          treated as a reference set and the other as a set to evaluate. It is a
                          refactored version of the agreement action.

Pre-trained models

KPWr NER for Polish

The package contains three models for recognition named entities according to KPWr NE guidelines.

nam — named entity boundaries,
top9 — coarse-grained categories,
n82 — fine-grained categories.

Expected output:

Service mode (using RabbitMQ)

Introduction

Liner2 can be run as a service which listen to a RabbitMQ queue for upcomming requests (liner2-input). and submit the results to another queue (liner2-output). The input message (send by the client) should have the following format:

ROUTE_KEY PATH

Where:

ROUTE_KEY — name of a route used to post the results to the output queue. The routing key is used by the client to receive the response for their request ignoring others,
PATH — an absolute path to the file to process.

For example:

client-001 /tmp/document.txt

The message send by the service will contain path to a file which contains the output of processing.

Running the service

./liner2-daemon rabbitmq -m liner26_model_ner_nkjp/config-nkjp-poleval2018.ini -i plain:wcrft

Expected output:

 INFO [Thread-1] (RabbitMqWorker.java:91) - Listing to RabbitMQ on channel liner2-input ...
Consumer amq.ctag-m6D9fIMI_Qsm61BH7HoxlA registered

It is possible to run more than one instance of ./liner2-daemon rabbitmq. However, all of them should use the same model and input format.

Testing

Folder stuff/python contains a Python script to test the communication with the service. The script takes a text to process, stores the texts in a temporal file, generates a routing key, send both to the liner2-input queue and listen to liner2-output. After receiving the response it reads the output file, removes both temporal files and prints the output.

python3 stuff/python/liner2rmq.py -t "Pani Ala Nowak mieszkw w Zielonej Górze"

The output should be as follows:

[INFO] Temp route: route-1DVRP4
[INFO] Temp input file: /tmp/amu7_3at
[INFO] Sent msg 'route-1DVRP4 /tmp/amu7_3at' to liner2-input
