DownloadPHP Stanford NLP Datastore
Stores NLP data from Stanford CoreNLP server.
What does it do?
It analyses a text using Stanford CoreNLP server, then stores the result.
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?
This package depends on Stanford CoreNLP Server
http://stanfordnlp.github.io/CoreNLP/index.html#download
This package also depends on PHP-Stanford-CoreNLP-Adapter
https://github.com/DennisDeSwart/php-stanford-corenlp-adapter
Note: since this package contains a full version of the CoreNLP Adapter, you can use all of it's features with this package.

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
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.
Example output
See
- "datastore_result_a.PNG"
- "datastore_result_b.PNG"
- "datastore_result_search.PNG"
and "example.db", this is how a filled database looks like
