Does anyone here use parsers and know of practical applications for them?

  My main use case is unsupervised feature extraction from blob text. One application may be to extract all noun entities from a news article, so you can automatically figure out who the article is about.

    Good idea! However, chunking (shallow parsing) might be enough for that purpose.

  Features you can use for other stuff, like entity detection. E.g. AlchemyAPI has a cool demo, where they can detect names of diseases, cities, etc. I suspect the parts of speech would improve the accuracy for tagging words that have multiple meanings. I used the disease bit on AlchemyAPI for https://www.findlectures.com https://www.findlectures.com, to make facets for a health topics: https://www.findlectures.com/?p=1&class1=Science&category_l2_Science=Health https://www.findlectures.com/?p=1&class1=Science&category_l2...

  I use this parser in particular at work designing a closed-domain chatbot.

    Do you mind going into more detail, since most chatbots just use rules and keyword words.
