Properly structured and accurately annotated data is at the core of what makes AI/ML models work. Our proprietary platform and curated crowd management workflows pair various tasks with the right workers, enabling delivery of high quality output consistently, and at a low cost.

Data can be annotated for a large number of use cases including sentiment, demographics, required responses, non-verbal speech, and any other customized meta-data.

The Power of High Quality Data Annotation

Real-Life Scenario Application

One day, Robert calls his doctor’s office to pay a bill. He was greeted by a chat bot over the phone asking what the office could help him with. Annoyed by the fact that he wasn’t speaking with a person, he said “I want to talk with a human!” in a frustrated tone.

The chat bot responded by saying “We know these are frustrating times but let’s try to be nice. How can I help direct your call?” Robert, who notably was upset and in a bad mood to start with, again angrily requested to speak to a human and started cursing at the chat bot. Rather than transferring him to a receptionist, the chat bot politely told him to call back when he was less frustrated – and hung up.

Quality Outputs for Every Use Case

How did the chat bot know that he was upset? How could it tell he needed to cool down? That’s where the power of Data Annotation comes in.

By annotating your data with sentiment, specific word usage, and questions vs answers, we can help your AI and chat bots detect when someone is upset, needs priority assistance, or ask certain questions in order to properly direct their call.

In turn, you’ll be able to save on valuable Human Resources – and provide more efficient, quick, and correct service to your customers and your staff. The use cases for this technology are endless!

Our Data Annotation Capabilities

Not sure which capabilities you need? We can help make that decision together. You can either submit your audio to be transcribed or send us your transcriptions directly for annotation.

Transcript specialization examples - The Gold Standard in transcription services
Sentiment Identification

Identify the emotional impact of a statement and overall feeling of the context; ie is this happy/funny/sad? - The Gold Standard in transcription services
Relationship Tagging

Identify how one word relates to the other words in a sentence for context. Essentially, this helps the computer identify the verb, noun, and adjective. - The Gold Standard in transcription services
Quantitative Research Coding

TranscribeMe can help with that daunting task of sorting through enormous amounts of data and annotating the data with numerical or tag codes.

Provide us with your codebook, and your data, and we will get that overwhelming task done for you! - The Gold Standard in transcription services
Data Validation

We can help review and audit client phone calls to ensure they meet all of the necessary call requirements, such as tagging identifications.

Example: After we annotate the data, it can then be fed directly into an AI system that can then recognize if each employee is meeting the call quality criteria that a call center may require.

Custom transcription project examples - The Gold Standard in transcription services
Semantic Annotation

Identify and annotate regional dialects and idiosyncrasies to help the computer understand how a term relates to others it knows – ie “you all” and “y’all.” - The Gold Standard in transcription services
Named Entity Recognition

This helps the computer apply an entity label to text, and identify a word that represents an entity it can classify – ie a Name, Address, or an Account Number. - The Gold Standard in transcription services
Bounding Box

Bounding boxes are boxes used to define the location of the target object, and help the computer understand what images contain which objects.

This is often used for creating visual captchas – ie ‘click three images in the captcha that contain a truck in it’. We will train the AI to know which images contain which objects. - The Gold Standard in transcription services
Data Labeling & Classification

Data labeling is the process of adding tags or labels to raw transcript data that specifies what the content is based on what the client is looking to classify.

For instance we can classify and label types of calls for a call center such as ‘Service Call’, ‘Problem with Service Call’, ‘Make a Payment Call’ etc and classify for a client. The classification and tagging options are endless.
