This is the Alice project webpage of the human interface library (simply called hi) demonstrating a simple language model example, how searching for a location on a map could be interpreted -currently without taking any action. Here you can play around online with a precompiled js lib of hi (not the most recent version though) embedded in a website but it'd work as well via Node.js.
The language model contains only a handful of words (show, restaurant, location, of, in), grammar and semantics required to process the input. Here are some examples you can copy & paste in the input field where words like 'abc', 'def', 'erding', 'budapest', 'hungary' and 'thai' are not part of the dictionary, just so called constants so you can use whatever you like there. After hitting the Enter key or the Submit button, you'll get json structured analyses along with the emerging errors in the text area below where you can check out the result and the tags used. If you're interested, you may open up your browser's console to see what's logged there during the analysis.
