Is there an OR operator in spaCy's Matcher patterns?












0















Using spaCy 2.x, how to extract noun phrases based on parts of speech? I want to use patterns with spaCy's Matcher but combinations are too many to create them manually.



Indeed, in my logic, a noun phrase is a group of one or many tokens that:




  • must end with a NOUN token

  • can also contain zero, one or many ADJ, PROPN, NOUN tokens in any order before the ending NOUN token


For example:




  • NOUN ADJ NOUN

  • NOUN

  • ADJ ADJ NOUN NOUN


Is there an "OR" operator so I could use a pattern such as the below (using an array of matching POS, for example)?



matcher.add(



    'NounPhrases', 

    None, 

    [

        {'POS': ['ADJ','NOUN','PROPN'], 'OP': '*'},

        {'POS': 'NOUN'}

    ]

)





python-3.x nlp spacy

          Origin of the phrase “under your belt”?

Question : What is the origin of the phrase "under your belt"? A google search revealed some webpages (e.g. [1]) that assert its origin is related to consumption of food -- once a meal has been eaten, it's under your belt (which is a relief). However, with such websites, I have no way to determine fact from "random guy on the internet making stuff up". etymology idioms ...
