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 [email protected]: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.
