Kuvulala kwachiwindi chifukwa cha mankhwala ndi chimodzi mwa zifukwa zomwe zimayambitsa kuchepa kwa mankhwala.Kuthekera kodziwiratu zomwe zimachitika m'chiwindi cha omwe akufuna kugwiritsa ntchito mankhwalawo kuchokera kumagulu awo amankhwala ndikofunikira kuti zithandizire kutsogolera ntchito zoyeserera zopeza mankhwala opangira mankhwala otetezeka.Mu phunziro ili, tapanga deta yamagulu a 951 omwe amanenedwa kuti amatulutsa zotsatira zosiyanasiyana m'chiwindi mu mitundu yosiyanasiyana, kuphatikizapo anthu, makoswe, ndi tizilombo toyambitsa matenda.Zotsatira za chiwindi za deta iyi zidapezedwa ngati metadata yotsimikizika, yopangidwa kuchokera ku MEDLINE abstracts pogwiritsa ntchito njira yapadera ya lexical ndi zinenero ndi malamulo a ontological.Tasanthula deta iyi pogwiritsa ntchito njira zodziwika bwino za cheminformatics ndikuyankha mafunso angapo okhudzana ndi kuphatikizika kwamitundu yosiyanasiyana yachiwindi, mankhwala omwe amakhudza chiwindi mwa anthu, komanso kuneneratu ngati mankhwala omwe aperekedwa angayambitse chiwindi mwa anthu.Tinapeza kuti concordance ya zotsatira za chiwindi inali yochepa (ca. 39-44%) pakati pa mitundu yosiyanasiyana, kukweza mwayi wakuti mitundu yeniyeni ingadalire pazinthu zenizeni za kapangidwe ka mankhwala.Mankhwalawa adaphatikizidwa ndi kufanana kwawo kwamankhwala, ndipo mankhwala ofananawo adawunikidwa kuti awonetse kufanana komwe kumayembekezeredwa kwachiwindi chodalira mitundu yawo.Nthawi zambiri, mbiri yofananira idawonedwa kwa mamembala amgulu lomwelo, koma zina zidawoneka ngati zakunja.Otsatsawo anali mutu wa kukonzanso kokhazikika kuchokera ku MEDLINE komanso magwero ena a deta.Nthawi zina, zotsimikizira zachilengedwe zowonjezera zidadziwika, zomwe zinali zogwirizana ndi ziyembekezo zochokera kuzinthu zofananira ndi mankhwala.Zomwe zanenedwazo zidasinthidwanso kukhala zofotokozera zamakemikolo oyambira (mwachitsanzo, zotsatira za chiwindi motsutsana ndi vuto la chiwindi), ndipo mitundu ya binary quantitative structure-activity relationship (QSAR) idapangidwa kuti iwonetsere ngati gulu lingayembekezere kutulutsa chiwindi mwa anthu.Ngakhale kuoneka kosiyana kwa deta, zitsanzo zawonetsa mphamvu zabwino zolosera zomwe zimawunikiridwa ndi njira zakunja zovomerezeka za 5.Mphamvu zolosera zakunja zamitundu ya binary za QSAR zidatsimikiziridwanso ndikugwiritsa ntchito kwawo kumagulu omwe adabwezedwa kapena kuphunziridwa pambuyo poti chitsanzocho chinapangidwa.Monga momwe tikudziwira, iyi ndi phunziro loyamba la kuneneratu kwa poizoni wa mankhwala omwe adagwiritsa ntchito QSAR modelling ndi njira zina za cheminformatics ku deta yowunikira yomwe imapangidwa ndi makina opangira malemba omwe ali ndi zolemba zochepa, ndikutsegula mwayi watsopano wopanga ndi kuyerekezera mankhwala a toxicology. deta.
