the necessity of syntax markers two experiments with artificial languages
Thomas Green
The primary resource gathered is a `` phrasal lexicon , '' constructed by extracting over 200,000 phrases from the Penn Treebank and having them translated into French by three Web-based machine translation ( MT ) systems . Each set of translations is stored separately , and for each set the `` marker hypothesis '' ( Green 1979 ) is used to segment the phrasal lexicon into a `` marker lexicon . '' The marker hypothesis is a universal psycholinguistic constraint which states that natural languages are '' marked '' for complex syntactic structure at surface form by a closed set of specific lexemes and morphemes .
