TopicModeling.cs

TopicModeling.cs demonstrates how to create topic detection jobs that read from an S3 bucket and outputs to another S3 bucket using the Comprehend client.

using System; using Amazon.Comprehend; using Amazon.Comprehend.Model; namespace ComprehendSamples1 { class TopicModeling { // Helper method for printing properties static private void PrintJobProperties(TopicsDetectionJobProperties props) { Console.WriteLine("JobId: {0}, JobName: {1}, JobStatus: {2}, NumberOfTopics: {3}\nInputS3Uri: {4}, InputFormat: {5}, OutputS3Uri: {6}", props.JobId, props.JobName, props.JobStatus, props.NumberOfTopics, props.InputDataConfig.S3Uri, props.InputDataConfig.InputFormat, props.OutputDataConfig.S3Uri); } public static void Sample() { var comprehendClient = new AmazonComprehendClient(Amazon.RegionEndpoint.USWest2); String inputS3Uri = "s3://input bucket/input path"; InputFormat inputDocFormat = InputFormat.ONE_DOC_PER_FILE; String outputS3Uri = "s3://output bucket/output path"; String dataAccessRoleArn = "arn:aws:iam::account ID:role/data access role"; int numberOfTopics = 10; var startTopicsDetectionJobRequest = new StartTopicsDetectionJobRequest() { InputDataConfig = new InputDataConfig() { S3Uri = inputS3Uri, InputFormat = inputDocFormat }, OutputDataConfig = new OutputDataConfig() { S3Uri = outputS3Uri }, DataAccessRoleArn = dataAccessRoleArn, NumberOfTopics = numberOfTopics }; var startTopicsDetectionJobResponse = comprehendClient.StartTopicsDetectionJob(startTopicsDetectionJobRequest); var jobId = startTopicsDetectionJobResponse.JobId; Console.WriteLine("JobId: " + jobId); var describeTopicsDetectionJobRequest = new DescribeTopicsDetectionJobRequest() { JobId = jobId }; var describeTopicsDetectionJobResponse = comprehendClient.DescribeTopicsDetectionJob(describeTopicsDetectionJobRequest); PrintJobProperties(describeTopicsDetectionJobResponse.TopicsDetectionJobProperties); var listTopicsDetectionJobsResponse = comprehendClient.ListTopicsDetectionJobs(new ListTopicsDetectionJobsRequest()); foreach (var props in listTopicsDetectionJobsResponse.TopicsDetectionJobPropertiesList) PrintJobProperties(props); } } }
