NLTK, Gensim, Qauv, thiab lwm yam Python modules yog heev zoo ntawm ua ntawv nyeem . Lawv lub cim xeeb siv thiab kev ua tau zoo yog qhov tsim nyog heev. Python scale vim ua ntawv nyeem yog ib qho teeb meem scalable yooj yim heev. Koj tuaj yeem siv multiprocessing yooj yim heev thaum parsing / tagging / chunking / extracting cov ntaub ntawv.

Raws li txoj cai, kev sau ntawv hauv Python yog dab tsi?

Python - Kev sau ntawv . Python Programming tuaj yeem siv los ua cov txheej txheem ntawv nyeem cov ntaub ntawv rau qhov yuav tsum tau muaj nyob rau hauv ntau yam ntawv nyeem cov ntaub ntawv tsom xam. Python's Natural Language Toolkit (NLTK) yog ib pawg ntawm cov tsev qiv ntawv uas tuaj yeem siv los tsim xws li Kev sau ntawv tshuab.

Ib sab saum toj no, qhov twg zoo dua NLTK lossis spaCy? spaCy muaj kev txhawb nqa rau cov lus vectors whereas NLTK tsis. Raws li spaCy siv qhov tseeb thiab zoo tshaj plaws algorithms, nws cov kev ua tau zoo feem ntau zoo li piv rau NLTK . Raws li peb tuaj yeem pom hauv qab no, hauv lo lus tokenization thiab POS-tagging spaCy ua zoo dua tab sis nyob rau hauv kab lus tokenization, NLTK kev ua tau zoo spaCy.

Tsis tas li ntawd, koj ua li cas ntxuav cov ntawv hauv Python?

Cia peb ua qauv qhia qhov no nrog lub raj xa dej me me ntawm kev npaj cov ntawv suav nrog:

  1. Load cov ntawv nyoos.
  2. Faib rau hauv tokens.
  3. Hloov mus rau tus lej qis.
  4. Tshem cov cim cim los ntawm txhua tus token.
  5. Lim tawm cov tokens uas tsis yog cov tsiaj ntawv.
  6. Lim tawm cov tokens uas yog cov lus nres.

Cov tswv yim ua cov ntawv nyeem yog dab tsi?

cov tswv yim ua cov ntawv nyeem . Cov no suav nrog kev kos duab ntawm cov ntsiab lus, semantic, grammatical thiab phonic paub hauv txoj hauv kev los ua haujlwm tawm dab tsi ntawv nyeem hais. Lawv suav nrog kev kwv yees, paub cov lus thiab ua cov lus tsis paub, saib xyuas kev nkag siab, txheeb xyuas thiab kho qhov yuam kev, nyeem ntawv thiab rov nyeem dua.
