Quickstart

If you are using Maven, add this to your pom.xml file

<dependency>

<groupId>com.google.cloud</groupId>

<artifactId>google-cloud-language</artifactId>

<version>0.17.1-beta</version>

</dependency>

If you are using Gradle, add this to your dependencies

If you are using SBT, add this to your dependencies

libraryDependencies += "com.google.cloud" % "google-cloud-language" % "0.17.1-beta"

Authentication

See the [Authentication](https://github.com/GoogleCloudPlatform/google-cloud-java#authentication) section in the base directory's README.

About Google Cloud Natural Language

Google [Cloud Natural Language API][cloud-language-docs] provides natural language understanding technologies to developers, including sentiment analysis, entity analysis, and syntax analysis. This API is part of the larger Cloud Machine Learning API family.

See the ``google-cloud`` API [natural language documentation][language-api] to learn how to use this Cloud Natural Language API Client Library.

Getting Started

You will need a [Google Developers Console](https://console.developers.google.com/) project with the Natural Language API enabled. [Follow these instructions](https://cloud.google.com/docs/authentication#preparation) to get your project set up. You will also need to set up the local development environment by [installing the Google Cloud SDK](https://cloud.google.com/sdk/) and running the following commands in command line: `gcloud auth login` and `gcloud config set project [YOUR PROJECT ID]`.

You'll need to obtain the `google-cloud-language` library. See the [Quickstart](#quickstart) section to add `google-cloud-language` as a dependency in your code.

In [AnalyzeSentiment.java](../google-cloud-examples/src/main/java/com/google/cloud/examples/language/snippets/AnalyzeSentiment.java) we put a quick start example, which shows how you can use Google Natural Language API to automatically analize a sentiment of a text message.

Troubleshooting

To get help, follow the instructions in the [shared Troubleshooting document](https://github.com/GoogleCloudPlatform/gcloud-common/blob/master/troubleshooting/readme.md#troubleshooting).

Java Versions

Java 7 or above is required for using this client.

Versioning

This library follows [Semantic Versioning](http://semver.org/).

It is currently in major version zero (``0.y.z``), which means that anything may change at any time and the public API should not be considered stable.
