The complete URL to be used is: childes.childes_url_base + urlbase + fileid.replace('.xml', '.cha') If no urlbase is passed, we try to calculate it. This requires that the childes corpus was set up to mirror the folder hierarchy under childes.psy.cmu.edu/data-xml/, e.g.: nltk_data/corpora/childes/Eng-USA/Cornell/??? or nltk_data/corpora/childes/Romance/Spanish/Aguirre/??? The function first looks (as a special case) if "Eng-USA" is on the path consisting of +fileid; then if "childes", possibly followed by "data-xml", appears. If neither one is found, we use the unmodified fileid and hope for the best. If this is not right, specify urlbase explicitly, e.g., if the corpus root points to the Cornell folder, urlbase='Eng-USA/Cornell'. iÿÿÿÿNt/s\\s /childes/s$(?i)/childes(?:/data-xml)?/(.*)\.xmliseng-usasEng-USA/s/(?i)Eng-USA/(.*)\.xmls.xmliüÿÿÿs.chasOpening in browser:( t webbrowserR;R tsubtlowerR.tendswithtchildes_url_baset open_new_tabtprint(R RturlbaseR{R;tpathtfullturl((sl/private/var/folders/cc/xm4nqn811x9b50x1q_zpkmvdjlphkp/T/pip-build-FUwmDn/nltk/nltk/corpus/reader/childes.pyt webview_file†s"    N(t__name__t __module__t__doc__RRRRRRRRR!R R+R*R6R4R7RDRCRRR†(((sl/private/var/folders/cc/xm4nqn811x9b50x1q_zpkmvdjlphkp/T/pip-build-FUwmDn/nltk/nltk/corpus/reader/childes.pyRs,            ' ~c CsÚ|s%ddlm}|dƒ}ny‘t|dƒ}x{|jƒd D]i}d}d}xQ|j|ƒdjƒD]6\}}|dkr•|}n|d krt|}qtqtWtd ||d ƒtd |j|ƒd dƒtd|j|dtƒd dƒtd|j |ƒd dƒtd|j|ddƒd dƒtd|j|ddƒd dƒtd|j|dtƒd dƒtd|j|dtƒd dƒtd|j |ƒd dƒxZ|j |ƒdjƒD]?\}} x0| jƒD]"\}}td||d|ƒqúWqáWtd t |j |ƒƒƒtd!t |j|dtƒƒƒtd"|j |ƒƒtd#|j |d$tƒƒtd%|j|ƒƒtƒqHWWntk rÕ} td&ƒnXd'S((sp The CHILDES corpus should be manually downloaded and saved to ``[NLTK_Data_Dir]/corpora/childes/`` iÿÿÿÿ(Rfs!corpora/childes/data-xml/Eng-USA/s.*.xmliR]itCorpustIdtReadings .....swords:is...swords with replaced words:Rs ...swords with pos tags:swords (only MOT):RtMOTswords (only CHI):R3sstemmed words:Rs!words with relations and pos-tag:Rs sentence:is participantR_s num of sent:snum of morphemes:sage:s age in month:R5sMLU:sSThe CHILDES corpus, or the parts you need, should be manually downloaded from http://childes.psy.cmu.edu/data-xml/ and saved at [NLTK_Data_Dir]/corpora/childes/ Alternately, you can call the demo with the path to a portion of the CHILDES corpus, e.g.: demo('/path/to/childes/data-xml/Eng-USA/") N(t nltk.dataRfRR R!R%RRRRRR+RLR6RDt LookupError( t corpus_rootRftchildestfileR!t corpus_idR(R)R2tvaluesR:((sl/private/var/folders/cc/xm4nqn811x9b50x1q_zpkmvdjlphkp/T/pip-build-FUwmDn/nltk/nltk/corpus/reader/childes.pytdemoºsD&  #####&"t__main__(R‰t __future__Rt __docformat__R;t collectionsRt nltk.utilRt nltk.compatRtnltk.corpus.reader.utilRtnltk.corpus.reader.xmldocsRRR/RRR•R‡(((sl/private/var/folders/cc/xm4nqn811x9b50x1q_zpkmvdjlphkp/T/pip-build-FUwmDn/nltk/nltk/corpus/reader/childes.pyt s ÿŸ 2
