Kodi kusanthula ndi kusanthula ndi chiyani amasangalatsa anthu ambiri. Kuwerengetsa kumayenera kumveka ngati njira yomwe chikalata china chimasanthulidwira malinga ndi mawu ndi kaphatikizidwe. Paraer (syntactic analyzer) ndi gawo la pulogalamu yomwe ili ndi udindo wowerenga zomwe zili mumayendedwe azokha ndikupeza zidutswa zofunikira.
Kodi kufotokozera ndi chiyani?
Kuwerengera kumakupatsani mwayi wambiri wazidziwitso munthawi yochepa kwambiri. Izi zikutanthauza kuwunika kwadongosolo lazidziwitso zomwe zaikidwa patsamba la intaneti. Chifukwa chake, kuwerengera kumakhala kosavuta kuposa ntchito yamanja yomwe imafunikira nthawi yochuluka komanso khama.
Otsatsa ali ndi izi:
- Kusintha deta, kukulolani kuti mukhale ndi zambiri zaposachedwa (mitengo yosinthira, nkhani, nyengo).
- Kutola ndi kubwereza zinthu zakanthawi yomweyo kuchokera kumawebusayiti ena kuti ziwonetsedwe pa intaneti. Zomwe zimapezeka polemba nthawi zambiri zimalembedwanso.
- Kulumikiza mitsinje ya data. Zambiri zimalandiridwa kuchokera kuzinthu zosiyanasiyana, zomwe ndizothandiza kwambiri mukamadzaza masamba azankhani.
- Kugawanitsa kumathandizira kwambiri pantchitoyo ndi mawu osakira kapena mawu. Chifukwa cha izi, zimakhala zotheka kusankha mwachangu zofunikira zofunikira pantchitoyo.
Mitundu ya Parser
Kupeza chidziwitso pa intaneti ndichinthu chovuta kwambiri, chachizolowezi komanso chanthawi yayitali. Otsatsa amatha kukonza, kupanga ndi kusanja magawo a mkango tsiku limodzi pofunafuna zomwe angafune.
Kugawana kumakupatsani mwayi wowongolera zapaderazi polemba mwachangu komanso molondola zomwe zili patsamba masauzande ambiri ndi zomwe zaperekedwa.
Lero, mutha kutsitsa kapena kugula mapulogalamu ambiri othandiza, kuphatikizapo Import.io, Webhose.io, Scrapinghub, ParseHub, Spinn3r ndi ena.
Wolemba masamba ndi chiyani
Mauthenga a masamba amachitika malinga ndi pulogalamu yomwe idakhazikitsidwa, poyerekeza kuphatikiza kwamawu ndi zomwe zimapezeka pa intaneti.
Momwe mungagwirire ntchito ndi zomwe mwalandira zalembedwa mu mzere wazamalamulo, wotchedwa "kuwonetsa pafupipafupi". Zimapangidwa kuchokera kuzizindikiro ndikukonzekera mfundo zosakira.
Wolemba tsambali amadutsa magawo angapo:
- Kusaka zomwe mukufuna mumtundu woyambirira: kupeza mwayi wopezeka patsamba la intaneti, kutsitsa, kutsitsa.
- Kupeza ntchito kuchokera patsamba la webusayiti, ndikutulutsa zofunikira kuchokera patsamba la pulogalamuyo.
- Kapangidwe ka lipoti molingana ndi zofunikira zomwe zakhazikitsidwa (kujambula zambiri pamasamba, zolemba).
