Under the hood of our tools, there's a lot of Natural Language Processing (NLP) going on. Since human language is often "messy" and ambiguous, we process that language to provide your students with top-notch tools that can help teach them a second language.
For example, our vocabulary tool (Linguatorium Lexis) takes example sentences that other teachers have used in their classrooms and intelligently annotates them to highlight the target word. This task might be easy for a human, but it can be tough for the computer!
So, we've recently added the following improvements:
- Use lemmatization to help identify words with the same base form (see how exhibit, exhibits, and exhibited are all highlighted below?)
- Consider part-of-speech when selecting examples (you don't want an example about farm tools to learn the verb combine, right?)
- Target words are highlighted automatically now! (Don't worry, you can change it if you like.)
