Watson Developer Cloud Unity SDK

Build Status

Use this SDK to build Watson-powered applications in Unity. It comes with a set of prefabs that you can use to develop a simple Watson application in just one minute.

Table of Contents

Before you begin

Ensure that you have the following prerequisites:

  • An IBM Bluemix account. If you don't have one, sign up.
  • Unity. You win! You can use the free Personal edition.
  • Change the build settings in Unity (File > Build Settings) to any platform except for web player. The Watson Developer Cloud Unity SDK does not support Unity Web Player.

Getting the Watson SDK and adding it to Unity

You can get the latest SDK release by clicking here.

Installing the SDK source into your Unity project

Move the unity-sdk directory into the Assets directory of the Unity project. Rename the SDK directory from unity-sdk to Watson.

Configuring your service credentials

You will need the 'username' and 'password' credentials for each service. Service credentials are different from your Bluemix account username and password.

  1. Determine which services to configure.
  2. If you have configured the services already, complete the following steps. Otherwise, go to step 3.
    1. Log in to Bluemix at https://bluemix.net.
    2. Navigate to the Dashboard on your Bluemix account.
    3. Click the tile for a service.
    4. Click Service Credentials. Note: If your browser window is too narrow, the service options may be collapsed. Click on the upward facing double arrow next to "Back to Dashboard..." on the upper left to expand the sidebar.
    5. Copy the content in the Service Credentials field, and paste it in the credentials field in the Config Editor (Watson -> Config Editor) in Unity.
    6. Click Apply Credentials.
    7. Repeat steps 1 - 5 for each service you want to use. services-0
  3. If you need to configure the services that you want to use, complete the following steps.
    1. In the Config Editor (Watson -> Config Editor), click the Configure button beside the service to register. The service window is displayed.
    2. Under Add Service, type a unique name for the service instance in the Service name field. For example, type 'my-service-name'. Leave the default values for the other options.
    3. Click Create.
    4. Click Service Credentials. Note: If your browser window is too narrow, the service options may be collapsed. Click on the upward facing double arrow next to "Back to Dashboard..." on the upper left to expand the sidebar.
    5. Copy the content in the Service Credentials field, and paste it in the empty credentials field in the Config Editor in Unity.
    6. Click Apply Credentials.
    7. Repeat steps 1 - 5 for each service you want to use. services-1
  4. Click Save, and close the Config Editor.

Note: The Config.json file is saved as plain text in the StreamingAssets directory. It is the user's responsibility to secure the credentials.

IBM Watson Services

Speech to Text

Use the Speech to Text service to recognize the text from a .wav file. Assign the .wav file to the script in the Unity Editor. Speech to text can also be used to convert an audio stream into text. When using the Microphone Widget and publishing to iOS, the XCode project plist must be updated with a NSMicrophoneUsageDescription or the application will crash silently.

[SerializeField]
private AudioClip m_AudioClip = new AudioClip();
private SpeechToText m_SpeechToText = new SpeechToText();

void Start()
{
  m_SpeechToText.Recognize(m_AudioClip, HandleOnRecognize);
}

void HandleOnRecognize (SpeechResultList result)
{
  if (result != null && result.Results.Length > 0)
  {
    foreach( var res in result.Results )
    {
      foreach( var alt in res.Alternatives )
      {
        string text = alt.Transcript;
        Debug.Log(string.Format( "{0} ({1}, {2:0.00})\n", text, res.Final ? "Final" : "Interim", alt.Confidence));
      }
    }
  }
}

Text to Speech

Use the Text to Speech service to get the available voices to synthesize. The Text to Speech service also supports Speech Synthesis Markup Language (SSML). In addition, the service supports a service-specific expressive SSML element. See Text To Speech service examples for examples on how to create custom Text to Speech voice models.

TextToSpeech m_TextToSpeech = new TextToSpeech();
string m_TestString = "Hello! This is Text to Speech!";
string m_ExpressiveText = "<speak version=\"1.0\"><prosody pitch=\"150Hz\">Hello! This is the </prosody><say-as interpret-as=\"letters\">IBM</say-as> Watson <express-as type=\"GoodNews\">Unity</express-as></prosody><say-as interpret-as=\"letters\">SDK</say-as>!</speak>";

void Start ()
{
  m_TextToSpeech.Voice = VoiceType.en_GB_Kate;
  m_TextToSpeech.ToSpeech(m_TestString, HandleToSpeechCallback);

  m_TextToSpeech.Voice = VoiceType.en_US_Allison;
  m_TextToSpeech.ToSpeech(m_ExpressiveText, HandleToSpeechCallback);
}

void HandleToSpeechCallback (AudioClip clip)
{
  PlayClip(clip);
}

private void PlayClip(AudioClip clip)
{
  if (Application.isPlaying && clip != null)
  {
    GameObject audioObject = new GameObject("AudioObject");
    AudioSource source = audioObject.AddComponent<AudioSource>();
    source.spatialBlend = 0.0f;
    source.loop = false;
    source.clip = clip;
    source.Play();

    GameObject.Destroy(audioObject, clip.length);
  }
}

Language Translator

Select a domain, then identify or select the language of text, and then translate the text from one supported language to another.
Example: Ask how to get to the disco in Spanish using Language Translator service.

private LanguageTranslator m_Translate = new LanguageTranslator();
private string m_PhraseToTranslate = "How do I get to the disco?";

void Start ()
{
  Debug.Log("English Phrase to translate: " + m_PhraseToTranslate);
  m_Translate.GetTranslation(m_PhraseToTranslate, "en", "es", OnGetTranslation);
}

private void OnGetTranslation(Translations translation)
{
  if (translation != null && translation.translations.Length > 0)
    Debug.Log("Spanish Translation: " + translation.translations[0].translation);
}

Dialog

The Dialog service was deprecated on August 15, 2016, existing instances of the service will continue to function until August 9, 2017. Users of the Dialog service should migrate their applications to use the Conversation service. See the migration documentation to learn how to migrate your dialogs to the Conversation service.

Natural Language Classifier

Use Natural Language Classifier service to create a classifier instance by providing a set of representative strings and a set of one or more correct classes for each as training. Then use the trained classifier to classify your new question for best matching answers or to retrieve next actions for your application.

The SDK contains a Test Natural Language Classifier, which contains classes for temperature and conditions. Before you develop a sample application in the next section, train the classifier on the test data.

  1. Open the Natural Language Classifier Editor by clicking Watson -> Natural Language Classifier Editor.
  2. Locate the Test Natural Language Classifier, and click Train. The training process begins. The process lasts a few minutes.
  3. To check the status of the training process, click Refresh. When the status changes from Training to Available, the process is finished.
  4. Replace the ClassifierID below with the Natural Language Classifier instance's ClassifierID.
private NaturalLanguageClassifier m_NaturalLanguageClassifier = new NaturalLanguageClassifier();
private string m_InputString = "Is it hot outside?";
private string m_ClassifierId = <ClassifierID>;

void Start ()
{
  Debug.Log("Input String: " + m_InputString);
  m_NaturalLanguageClassifier.Classify(m_ClassifierId, m_InputString, OnClassify);
}

private void OnClassify(ClassifyResult result)
{
  if (result != null)
  {
    Debug.Log("Classify Result: " + result.top_class);
  }
}

Managing classifiers

You can use the Natural Language Classifier Editor to import and export classifier files, and create new classifiers and edit them.

Importing files for existing classifiers
  1. Click Watson -> Natural Language Classifier Editor. The Natural Language Classifier Editor window is displayed.
  2. Click Import.
  3. Navigate to the '.csv' file to import, and click Open. The file is imported.
  4. Click Train.
Creating new classifiers
  1. Click Watson -> Natural Language Classifier Editor. The Natural Language Classifier Editor window is displayed.
  2. In the Name field, specify a name for the classifier.
  3. Click Create.

Tone Analyzer

The Tone Analyzer service detects emotions, social tendencies and writing style from text input.

ToneAnalyzer m_ToneAnalyzer = new ToneAnalyzer();
    string m_StringToTestTone = "This service enables people to discover and understand, and revise the impact of tone in their content. It uses linguistic analysis to detect and interpret emotional, social, and language cues found in text.";

    void Start () {
        m_ToneAnalyzer.GetToneAnalyze( OnGetToneAnalyze, m_StringToTestTone, "TEST");
    }

    private void OnGetToneAnalyze( ToneAnalyzerResponse resp , string data)
    {
        Debug.Log("Response: " +resp + " - " + data);
    }

Tradeoff Analytics

The Tradeoff Analytics service helps people make better decisions when faced with multiple, sometimes conflicting, goals and alternatives.

        columnBrandName.full_name = "Brand";
        columnBrandName.goal = "max";
        columnBrandName.is_objective = true;
        columnBrandName.preference = new string[]{"Samsung", "Apple", "HTC"};
        columnBrandName.range = new CategoricalRange();
        ((CategoricalRange)columnBrandName.range).keys = new string[]{"Samsung", "Apple", "HTC"};

        listColumn.Add(columnPrice);
        listColumn.Add(columnWeight);

        problemToSolve.columns = listColumn.ToArray();


        List<Option> listOption = new List<Option>();

        Option option1 = new Option();

        public double price { get; set; }
        public double weight { get; set; }
        public string brand { get; set; }
    }

Conversation

With the IBM Watson™ Conversation service you can create cognitive agents - virtual agents that combine machine learning, natural language understanding, and integrated dialog scripting tools to provide outstanding customer engagements. A workspace should be created using Conversation tooling and a variable ConversationV1_ID should be set in the Config Editor with the Workspace ID (In the Config Editor, click Advanced Mode and click Add Variable). This is required for the service status check in the Config Editor.

private Conversation m_Conversation = new Conversation();
private string m_WorkspaceID = "car_demo_1";
private string m_Input = "Can you unlock the door?";

void Start () {
    Debug.Log("User: " + m_Input);
    m_Conversation.Message(OnMessage, m_WorkspaceID, m_Input);
}

void OnMessage (MessageResponse resp, string customData)
{
   foreach(Intent mi in resp.intents)
       Debug.Log("intent: " + mi.intent + ", confidence: " + mi.confidence);

   Debug.Log("response: " + resp.output.text);
}

Visual Recognition

Use the Visual Recognition service to classify an image against a default or custom trained classifier. In addition, the service can detect faces and text in an image.

Managing Classifiers

You can train and delete classifiers by directly accessing low level Visual Recognition methods.

Getting all classifiers

Get a list of all available classifiers

private VisualRecognition m_VisualRecognition = new VisualRecognition();

void Start()
{
    if(!m_VisualRecognition.GetClassifiers(OnGetClassifiers))
        Log.Debug("ExampleVisualRecognition", "Getting classifiers failed!");
}

private void OnGetClassifiers (GetClassifiersTopLevelBrief classifiers)
{
    if(classifiers != null && classifiers.classifiers.Length > 0)
    {
        foreach(GetClassifiersPerClassifierBrief classifier in classifiers.classifiers)
        {
            Log.Debug("ExampleVisualRecognition", "Classifier: " + classifier.name + ", " + classifier.classifier_id);
        }
    }
    else
    {
        Log.Debug("ExampleVisualRecognition", "Failed to get classifiers!");
    }
}
Finding a classifier

Find a classifier by name

private VisualRecognition m_VisualRecognition = new VisualRecognition();
private string m_classifierName = <Classifier Name>;

void Start()
{
    m_VisualRecognition.FindClassifier(m_classifierName, OnFindClassifier);
}

private void OnFindClassifier(GetClassifiersPerClassifierVerbose classifier)
{
    if(classifier != null)
    {
        Log.Debug("ExampleVisualRecognition", "Classifier " + m_classifierName + " found! ClassifierID: " + classifier.classifier_id);
    }
    else
    {
        Log.Debug("ExampleVisualRecognition", "Failed to find classifier by name!");
    }
}

Find a classifier by ID

private VisualRecognition m_VisualRecognition = new VisualRecognition();
private string m_classifierID = <Classifier ID>;

void Start()
{
    if(!m_VisualRecognition.GetClassifier(m_classifierID, OnGetClassifier))
            Log.Debug("ExampleVisualRecognition", "Getting classifier failed!");
}

private void OnGetClassifier(GetClassifiersPerClassifierVerbose classifier)
{
    if(classifier != null)
    {
        Log.Debug("ExampleVisualRecognition", "Classifier " + m_classifierID + " found! Classifier name: " + classifier.name);
    }
    else
    {
        Log.Debug("ExampleVisualRecognition", "Failed to find classifier by ID!");
    }
}
Training classifiers

Train a new classifier by uploading image data. Two compressed zip files containing at least two positive example files or one positive and one negative example file. The prefix of the positive example file is used as the classname for the new classifier <Class Name>_positive_examples. Negative examples zip must be named negative_examples. After a successful call, training the classifier takes a few minutes.

private VisualRecognition m_VisualRecognition = new VisualRecognition();

void Start()
{
    string m_positiveExamplesPath = Application.dataPath + "/Watson/Examples/ServiceExamples/TestData/<Class Name>_positive_examples.zip";
    string m_negativeExamplesPath = Application.dataPath + "/Watson/Examples/ServiceExamples/TestData/negative_examples.zip";
    if(!m_VisualRecognition.TrainClassifier("<Classifier Name>", "<Class Name>", m_positiveExamplesPath, m_negativeExamplesPath, OnTrainClassifier))
        Log.Debug("ExampleVisualRecognition", "Train classifier failed!");
}

private void OnTrainClassifier(GetClassifiersPerClassifierVerbose classifier)
{
    if(classifier != null)
    {
        Log.Debug("ExampleVisualRecognition", "Classifier is training! " + classifier);
    }
    else
    {
        Log.Debug("ExampleVisualRecognition", "Failed to train classifier!");
    }
}
Updating a classifier

Update an existing classifier by adding new classes, or by adding new images to existing classes. To update the existing classifier, use several compressed .zip files, including files containing positive or negative images .jpg or .png. You must supply at least one compressed file, with additional positive or negative examples.

Compressed files containing positive examples are used to add or create classes that define the updated classifier. The prefix that you specify for each positive example parameter is used as the class name within the classifier. The _positive_examples suffix is required. There is no limit on the number of positive example files you can upload in a single call. The compressed file containing negative examples is not used to create a class within the created classifier, but does define what the new classifier is not. Negative example files should contain images that do not depict the subject of any of the positive examples. You can only specify one negative example file in a single call.

private VisualRecognition m_VisualRecognition = new VisualRecognition();

void Start()
{
    string m_positiveExamplesPath = Application.dataPath + "/Watson/Examples/ServiceExamples/TestData/<Class Name>_positive_examples.zip";
   if(!m_VisualRecognition.UpdateClassifier(OnUpdateClassifier, "<ClassifierID>", "<Classifier Name>", "<Class Name>", m_positiveExamplesPath))
        Log.Debug("ExampleVisualRecognition", "Update classifier failed!");
}

private void OnUpdateClassifier(GetClassifiersPerClassifierVerbose classifier)
{
    if(classifier != null)
    {
        Log.Debug("ExampleVisualRecognition", "Classifier is retraining! " + classifier);
    }
    else
    {
        Log.Debug("ExampleVisualRecognition", "Failed to update classifier!");
    }
}
Deleting classifiers

Delete a classifier by Classifier ID

private VisualRecognition m_VisualRecognition = new VisualRecognition();
private string m_classifierToDelete = "<Classifier ID>";

void Start()
{
    if(!m_VisualRecognition.DeleteClassifier(m_classifierToDelete, OnDeleteClassifier))
        Log.Debug("ExampleVisualRecognition", "Deleting classifier failed!");
}

private void OnDeleteClassifier(bool success)
{
    if(success)
    {
        Log.Debug("ExampleVisualRecognition", "Deleted classifier " + m_classifierToDelete);
    }
    else
    {
        Log.Debug("ExampleVisualRecognition", "Failed to delete classifier by ID!");
    }
}

Classifying an image

You can classify an image via URL or by posting an image. You may also define multiple owners and classifiers to classify against in the call. Supported filetypes are .gif, .jpg, .png or .zip.

Personality Insights

The IBM Watson™ Personality Insights service provides a Representational State Transfer (REST) Application Programming Interface (API) that enables applications to derive insights from social media, enterprise data, or other digital communications. The service uses linguistic analytics to infer individuals' intrinsic personality characteristics, including Big Five, Needs, and Values, from digital communications such as email, text messages, tweets, and forum posts. The service can automatically infer, from potentially noisy social media, portraits of individuals that reflect their personality characteristics. The service can report consumption preferences based on the results of its analysis, and for JSON content that is timestamped, it can report temporal behavior.

AlchemyData News

Use the AlchemyData News service to provide news and blog content enriched with natural language processing to allow for highly targeted search and trend analysis. Now you can query the world's news sources and blogs like a database.

Getting News

AlchemyData News indexes 250k to 300k English language news and blog articles every day with historical search available for the past 60 days. You can query the News API directly with no need to acquire, enrich and store the data yourself - enabling you to go beyond simple keyword-based searches. You can request which fields to return and filter fields by string. All available fields can be accessed using Fields constants in the AlchemyData News Data Model.

private AlchemyAPI m_AlchemyAPI = new AlchemyAPI();

void Start()
{
    string[] returnFields = {Fields.ENRICHED_URL_ENTITIES, Fields.ENRICHED_URL_KEYWORDS};
    Dictionary<string, string> queryFields = new Dictionary<string, string>();
    queryFields.Add(Fields.ENRICHED_URL_RELATIONS_RELATION_SUBJECT_TEXT, "Obama");
    queryFields.Add(Fields.ENRICHED_URL_CLEANEDTITLE, "Washington");

    if (!m_AlchemyAPI.GetNews(OnGetNews, returnFields, queryFields))
        Log.Debug("ExampleAlchemyData", "Failed to get news!");
}

void OnGetNews(NewsResponse newsData, string data)

    if(newsData != null)
        Log.Debug("ExampleAlchemyData", "status: {0}", newsData.status);
}

Retrieve and Rank

The IBM Watson™ Retrieve and Rank service combines two information retrieval components in a single service: the power of Apache Solr and a sophisticated machine learning capability. This combination provides users with more relevant results by automatically reranking them by using these machine learning algorithms.

Getting clusters

Retrieves the list of Solr clusters for the service instance.

void Start()
{
  Log.Debug("ExampleRetrieveAndRank", "Attempting to get clusters!");
  if (!m_RetrieveAndRank.GetClusters(OnGetClusters))
    Log.Debug("ExampleRetrieveAndRank", "Failed to get clusters!");
}

private void OnGetClusters(SolrClusterListResponse resp, string data)
{
    if (resp != null)

        foreach (SolrClusterResponse cluster in resp.clusters)
            Log.Debug("ExampleRetrieveAndRank", "OnGetClusters | cluster name: {0}, size: {1}, ID: {2}, status: {3}.", cluster.cluster_name, cluster.cluster_size, cluster.solr_cluster_id, cluster.solr_cluster_status);
    }
    else
    {
        Log.Debug("ExampleRetrieveAndRank", "OnGetClusters | Get Cluster Response is null!");
    }
}

Creating a cluster

Provisions a Solr cluster asynchronously. When the operation is successful, the status of the cluster is set to NOT_AVAILABLE. The status must be READY before you can use the cluster.

void Start()
{
  Log.Debug("ExampleRetrieveAndRank", "Attempting to create cluster!");
  if (!m_RetrieveAndRank.CreateCluster(OnCreateCluster, "unity-test-cluster", "1"))
      Log.Debug("ExampleRetrieveAndRank", "Failed to create cluster!");
}

    }
    else
    {
        Log.Debug("ExampleRetrieveAndRank", "OnCreateClusters | Get Cluster Response is null!");
    }
}

Deleting a cluster

Stops and deletes a Solr Cluster asynchronously.

void Start()
{
  string clusterToDelete = "<cluster-to-delete>";
  Log.Debug("ExampleRetrieveAndRank", "Attempting to delete cluster {0}!", clusterToDelete);
  if (!m_RetrieveAndRank.DeleteCluster(OnDeleteCluster, clusterToDelete))

    {
        if (resp.solr_configs.Length == 0)
            Log.Debug("ExampleRetrieveAndRank", "OnGetClusterConfigs | no cluster configs!");

        foreach (string config in resp.solr_configs)
            Log.Debug("ExampleRetrieveAndRank", "OnGetClusterConfigs | solr_config: " + config);

        Log.Debug("ExampleRetrieveAndRank", "OnSaveConfig | success!");
    else
        Log.Debug("ExampleRetrieveAndRank", "OnSaveConfig | fail!");
}

Uploading a cluster config

Uploads a zip file containing the configuration files for your Solr collection. The zip file must include schema.xml, solrconfig.xml, and other files you need for your configuration. Configuration files on the zip file's path are not uploaded. The request fails if a configuration with the same name exists. To update an existing config, use the Solr configuration API.

Creating a ranker

Sends data to create and train a ranker and returns information about the new ranker.

When the operation is successful, the status of the ranker is set to Training. The status must be Available before you can use the ranker.

void Start()
{
  Log.Debug("ExampleRetrieveAndRank", "Attempting to create rankers!");

    else
        Log.Debug("ExampleRetrieveAndRank", "OnCreateRanker | Get Cluster Response is null!");
}

Rank

Returns the top answer and a list of ranked answers with their ranked scores and confidence values. Use the Get information about a ranker method to retrieve the status.

Use this method to return answers when you train the ranker with custom features. However, in most cases, you can use the Search and rank method.

void Start()
{
  Log.Debug("ExampleRetrieveAndRank", "Attempting to rank!");
  if (!m_RetrieveAndRank.Rank(OnRank, <testRankerID>, <testAnswerDataPath>))

Discovery

The IBM Watson™ Discovery Service uses data analysis combined with cognitive intuition in order to take your unstructured data and enrich it so that you can query it to return the information that you need from it.

Creating an environment

Creates an environment for the service instance. Note: You can create only one environment per service instance. Attempting to create another environment for the same service instance results in an error.

private Discovery m_Discovery = new Discovery();

{
  if (!m_Discovery.AddEnvironment(OnAddEnvironment, <environment-name>, <environment-description>, <environment-size>))
    Log.Debug("ExampleDiscoveryV1", "Failed to add environment");
}

private void OnAddEnvironment(Environment resp, string data)
{
  if (resp != null)
    Log.Debug("ExampleDiscoveryV1", "Added {0}", resp.environment_id, data);
  else

Developing a basic application in one minute

You can quickly develop a basic application that uses the Speech to Text service and the Natural Language Classifier service by using the prefabs that come with the SDK. Ensure that you prepare the test data before you complete the the following steps:

  1. Create a new scene and drag the following prefabs from Assets -> Watson -> Prefabs, and drop them in the Hierarchy tab:

    • MicWidget
    • SpeechToTextWidget
    • Natural Language Classifier Widget
    • ClassDisplayWidget
  2. Select the Natural Language Classifier Widget.

  3. In the Classifier Name field in the Inspector tab, specify TestNaturalLanguageClassifier.
  4. In the Natural Language Classifier Editor, expand the Test Natural Language Classifier , expand the classes, and determine which questions about the weather to ask to test the classifier.
  5. Run the application.
  6. Say your questions into the microphone to test the MicWidget, the SpeechToTextWidget, and the NaturalLanguageClassifierWidget.
