PHP Stanford NLP Datastore

, _(*1)

Stores NLP data from Stanford CoreNLP server., _(*2)

What does it do?

It analyses a text using Stanford CoreNLP server, then stores the result., _(*3)

Which data gets stored?

OpenIE: these are "Subject-Relation-Object" triples. The concept is similar to "Subject-Verb-Object" triples.

Named-Entities: if a word is a "Named Entity", like a Location, Name or Time, it will store this data

http://stanfordnlp.github.io/CoreNLP/ner.html

Coreference: if there is a reference to a word in another sentence.

How does it work?

You submit a text.
The text is analyzed by the Stanford CoreNLP server
Results are stored in a SQLite file based database. The database file is called "datastore.db"

https://sqlite.org/
https://github.com/sqlitebrowser

The results are displayed on screen
There is also a search form to find data

This package depends on Stanford CoreNLP Server

Download and unpack the files from this package.
Copy the files to your to your webserver directory. Usually "htdocs" or "var/www".
Run a Composer update to install the dependencies

Install as part of another project

Install Stanford CoreNLP Server. Check the "php-stanford-corenlp-adapter" package for an installation walkthrough
Add the following lines to your main project's "composer.json" require section:

    {
        "require": {
            "dennis-de-swart/php-stanford-nlp-datastore": "*"
        }
    }

Run a Composer update to install the dependencies

Copy these files from "/vendor/dennis-de-swart/php-stanford-nlp-datastore" to your webserver directory. Usually "htdocs" or "var/www".
- datastore.db
- bootstrap.php

Example code for your main project:

    // instantiate constants and the database
    require_once __DIR__.'/bootstrap.php';

    // startup Corenlp Adapter
    $coreNLP = new CorenlpAdapter();
    $coreNLP->getOutput($yourText);
    print_r($coreNLP->serverMemory); // result from CoreNLP Adapter

    // Save result to database
    $datastore = new Datastore($db->conn);
    $datastore->storeNLP($coreNLP);

Requirements

PHP 5.6 or higher: it also works on PHP 7
Java SE Runtime Enviroment, version 1.8
Stanford CoreNLP Server 3.7.0
Windows or Linux/Unix 64-bit OS, 8Gb or more memory recommended.
Composer for PHP

    https://getcomposer.org/

SQLite Browser

Important notes

Starting the CoreNLP server for the first time, takes some time because it will load a large amount of data.
After the first startup, the server will be much faster.
In my experience the Stanford CoreNLP server runs best with 8Gb of memory or more. Start the server with "-mx8g" instead of "-mx4g".
Also use version 3.7.0 of the server, this gives you the best and quickest results.
