Custom Annotation Solutions

Artificial Intelligence can solve even the most seemingly insurmountable problems, but only if developers have the volume and quality of data they need to train the AI effectively.

We help your machine learning algorithms interact more accurately with natural language.

Whether you need help collecting and annotating a new data set, or you need help labeling an existing database, Summa Linguae Technologies provides high-quality linguistic and semantic annotation.

Our services include part-of-speech tagging, identifying of specific words or motions, and semantic relations.

Semantic & Linguistic Annotation

If you are working with text or speech data, linguistic annotation is the key to properly training your algorithm.

Semantic annotation by both human and automated techniques ensures that your algorithm learns to recognize correct patterns and that your users get the results they were looking for.

Whether your solution needs to recognize information in English or foreign languages, accurate and localized natural language understanding is important to get the results you are looking for.

Labeled Data Use Cases

Reliable sentiment analysis allows you to identify trends in consumer reactions, something we will see more and more in our emerging technology — just imagine your car understanding when you are scared and slowing down.

You can achieve similar results by training your algorithm to react to certain events, such as sleeping, eating, or writing.

If you are interested in collecting multilingual data or labeling and classifying data from multilingual videos, talk to us about how we can support the successful localization of your products.
