Pre- Requirements

In order to be able to use the package, you need to have the following

• Azure Text Analytics.
  • You can learn how to configure one here: https://docs.microsoft.com/en-us/azure/cognitive-services/cognitive-services-apis-create-account
  • Get the access key and endpoint url https://docs.microsoft.com/en-us/azure/cognitive-services/text-analytics/how-tos/text-analytics-how-to-access-key
• IBM Personality Insights
  • You can learn how to create an account here: https://cloud.ibm.com/docs/services/personality-insights?topic=personality-insights-gettingStarted#gettingStarted
  • Get the username and password https://cloud.ibm.com/docs/services/watson?topic=watson-creating-credentials#creating-credentials

Analyze a given text

• Install the package https://www.nuget.org/packages/PTI.Analyzers/

• Create a new instance of TextAnalyzer and pass it the configured parameters.

• If you want to intercept the http responses received, configure the event handler for OnHttpResponseReceivedEventHandler

• Create a new instance of DataAnalyzer

• Invoke "AnalyzeTextAndGenerateExcelFileAsync". It will return a byte[] corresponding to the generated XLSX file.

• Do whatever you need to do with the generated bytes, such as save it to disk.

           TextAnalyzer textAnalyzer = new TextAnalyzer(new MSTextAnalyticsConfiguration(Configuration.MSTextAnalyticsKey,
                Configuration.MSTextAnalyticsEndpoint),
                new IBMWatsonClientConfiguration(Configuration.IBMPersonalityInsightsUsername,
                Configuration.IBMPersonalityInsightsPassword));
        textAnalyzer.OnHttpResponseReceivedEventHandler += TextAnalyzer_OnHttpResponseReceivedEventHandler;
        DataAnalyzer dataAnalyzer =
            new DataAnalyzer(
                textAnalyzer);
        var excelFileBytes = dataAnalyzer.AnalyzeTextAndGenerateExcelFileAsync(fileContents).Result;
        File.WriteAllBytes(@"C:\Temp\GeneratedExcelFile.xlsx", excelFileBytes);
  

Analyze a list of photos and generates temp files and byte[] with the modified image including the faces rectangles

• Requires having credentials for Azure Face API and Computer Vision

• Check Face API here https://docs.microsoft.com/en-us/azure/cognitive-services/face/overview

• Check Computer Vision here https://docs.microsoft.com/en-us/azure/cognitive-services/computer-vision/home

           PhotoAnalyzer photoAnalyzer = new PhotoAnalyzer(new MSFaceApiConfiguration(
            FACEKEY, FACEENDPOINT),
            new MSComputerVisionApiConfiguration(VISIONKEY,
            VISIONENDPOINT));
        DataAnalyzer dataAnalyzer = new DataAnalyzer(
            photoAnalyzer);
        List<PhotoInformation> lstPhotos = new List<PhotoInformation>();
        string testFile = @"C:\TestFilesDirectory\testFile.jpg";
        lstPhotos.Add(new PhotoInformation()
        {
            Filename = testFile,
            PhotoStream = File.OpenRead(testFile)
        });
        await dataAnalyzer.AnalyzePhotoStream(lstPhotos, Color.Blue, 10, @"C:\Temp\GeneratedFiles");
        foreach (var singlePhoto in lstPhotos)
        {
            var filenameWithoutPath = System.IO.Path.GetFileName(singlePhoto.Filename);
            var newFileFullPath = $@"C:\Temp\ModifiedPhoto{filenameWithoutPath}";
            File.WriteAllBytes(newFileFullPath, singlePhoto.ModifiedPhotoBytes);
        }
