Concrete
Introduction
Concrete is an attempt to map out various NLP data types in a Thrift schema for use in projects across Johns Hopkins University. This standardized schema allows researchers to use a common, underlying data model for all NLP tasks, and thus, facilitating integration between projects.
Requirements
Concrete requires the following:
- Java, 1.7 or greater
- Apache Maven, 3.0.4 or greater
- Apache Thrift
Installation
Note: by default, the thrift plugin uses:
/usr/local/bin/thrift
to locate the thrift executable. If you have installed this in a different location, update
<thrift.exe>
in the properties of core/pom.xml.
First, checkout our latest code:
git clone git@github.com:hltcoe/concrete.git
Running
mvn install
will install the plugin to your local repository.
Adding to your project
This plugin creates compiled Java classes that reflect our Thrift definitions. You can use these in your java code by adding the following dependency to your project's pom.xml file, once installed or deployed:
<dependency>
<groupId>edu.jhu.hlt.concrete</groupId>
<artifactId>concrete-core</artifactId>
<version>2.0.0-SNAPSHOT</version>
</dependency>
At this time, we do not have this hosted on a public maven server.
Using the code in your project
Compiled java classes end up in the edu.jhu.hlt.concrete package. The Thrift structures generate many classes; additional technical documentation can be found in the comments of the thrift definitions themselves.
