Soo ogow sida ay tirakoobku u caawinayaan sanduuqaaga nadiifka ah
Faylasha spam ee Bayesian waxay ku xisaabtamaan itimaalka fariin ah inuu yahay spam iyada oo ku saleysan waxyaabaha ku jira. Si ka duwan shaandhada sahlan ee sahlan, Bayaanka Spam filtering waxuu ka bartaa spam iyo boosteejo wanaagsan, taasoo keentay in aad u xooggan, is qabadsiinta iyo hufnaanta habka anti-spam in, ugu fiican ee dhan, si adag u celiyaa wax kasta oo been abuur ah.
Sidee Ayaad u Aqoonsan Doonta Boostada?
Ka feker sida aad u ogaato spam . Muuqaal degdeg ah ayaa badanaa ku filan. Waad ogtahay waxa uu spam u eg yahay, oo waad taqaanaa boosteejada fiican.
Itimaalka suurtagalka ah ee spam u eg sida boosteejo wanaagsan ayaa ku dhaw ... eber.
Falanqaynta Filterska Ku-saleysan Mabda 'Uma Beddabayn
Ma jeclaan laheyd haddii filimka spam ee otomaatikada ah ee sidan oo kale ah,
Tartanka sifooyinka spam-ku salaysan ee ku salaysan ayaa isku deyaya. Waxay raadiyaan erayada iyo sifooyinka kale ee caadiga ah ee spam. Wax walba oo astaamo ah ayaa loo qoondeeyey dhibcaha, dhibcaha spam ee fariinta oo dhan waxaa lagu xisaabiyaa dhibcooyinka shakhsiyeed. Qalabka dhibcaha ee qaar ka mid ah ayaa sidoo kale raadinaya astaamaha waraaqaha sharciga, hoos u dhigista dhibcaha ugu dambeeya farriinta.
Nidaamka sawirada buundada ee buuggu wuu shaqeynayaa, laakiin waxa kale oo uu leeyahay dhowr dhibaatooyin:
- Liiska dabeecadaha waxaa laga dhisay boostada (iyo boostada wanaagsan) ee la heli karo injineerada feylaha. Si aad u heshid war fiican oo ah spam caadiga ah qof kasta oo laga yaabo inuu helo, boostada waa in lagu uruuriyaa boqolaal cinwaanno email. Tani waxay wiiqaysaa waxtarka filimka, gaar ahaan sababtoo ah sifooyinka wanaagsan ee mailka way ka duwanaan doonaan qof kasta , laakiin tan lama xisaabin.
- Dabeecadaha la eegayo waa kuwo badan ama ka yar dhagax . Haddii spamiyayaashu ay isku dayaan in ay la qabsadaan (oo ay ka dhigaan spamadooda waxay u eg yihiin boosteejo fiican ee filtarrada), sifooyinka shaandhayntu waa in ay noqdaan kuwo isbarbardhigi doona - dadaal aad u weyn.
- Dhibcaha loo qoondeeyey erey kasta waxaa laga yaabaa inuu ku saleysan yahay qiyaas wanaagsan, laakiin wali waa ikhtiyaari. Iyo sida liiska dabeecadaha, waxay isbarbardhigi mayso adduunka isbedelka ee spam guud ahaan ama baahida qofeed ee shakhsi ahaaneed.
Bayesian Spam Filters Tweak Qalbigooda, Helitaanka Better iyo Si Fiican
Sifooyinka spam ee Bayesian waa nooc ka mid ah dhibcaha dhibco-ku-salaysan, sidoo kale. Hadafkoodu waa uu ka baxsan yahay dhibaatooyinka sahaminta sahlan ee sahlan, inkastoo, taasina si wayn ayuu u sameeyaa. Maaddaama daciifinta natiijooyinka liiska ay ku jiraan liiska astaamaha iyo astaamaha, liiskan waa la tirtiray.
Taa baddalkeeda, filimka spam ee Bayesian ayaa dhisaya liiska. Fikrad ahaan, waxaad ka bilowdaa farabadan (far waaweyn) farriimo aad uheshay sida spam, iyo farabadan ee boosteejo wanaagsan. Filters ayaa eegaya labadaba falanqaynta boostada iyo sidoo kale spam si loo xisaabiyo suurtogalnimada sifooyinka kala duwan ee muuqanaya spam, iyo boosteejo wanaagsan.
Sidee Foomka Baybalka ee Baybaanku wuxuu baari doonaa Email
Tilmaamaha sifooyinka Bayaanka ee spam ayaa eegi kara:
- ereyada jidhka farriinta, dabcan, iyo
- madaxdooda (tusaale ahaan kuwa soo diraya iyo wadooyinka fariimaha , tusaale ahaan!), laakiin sidoo kale
- Qodobo kale sida HTML / CSS code (sida midabada iyo qaabaynta kale), ama xataa
- kelmadaha kelmadaha, odhaahyada iyo
- Macluumaadka Meta (halkaas oo ah weedha gaar ah, tusaale ahaan).
Haddii ereyga, "Cartesian" tusaale ahaan, marnaba muuqan spam laakiin inta badan e-mail sharci ah oo aad hesho, itimaalka "Cartesian" waxay muujinaysaa spam waa u dhowdahay eber. "Toner", dhinaca kale, waxay u muuqataa mid gaar ah, iyo inta badan, spam. "Toner" waxay leedahay feejignaan aad u sarreeya oo lagu helo spam, oo aan ka badneyn 1 (100%).
Marka fariin cusub la yimaado, waxaa lagu falanqeynayaa filterka Baytiga ee Bayesian, iyo suurtagalnimada fariinta dhamaystiran ee spam waxaa lagu xisaabiyaa iyadoo la adeegsanayo sifooyinka shakhsi ahaaneed.
Ka feker fariin ay ku qoran tahay "Cartesian" iyo "toner". Kalmada ereyadan kelidii weli ma caddayn haddii aanu haysanno spam ama legitit mail. Tilmaamo kale (rajo ahaan iyo inta badanba) waxay muujinaysaa itimaal u saamaxaya shaandhaynta inay u kala soocdo farriinta sida spam ama boosteejo wanaagsan.
Bayesian Spam Filters waxay baran kartaa si otomaatig ah
Hadda waxaan leenahay kala-saarid, fariinta waxaa loo isticmaali karaa si loo baro filterka laftiisa. Xaaladdan, hadday suuragal tahay "Cartesian" oo muujinaysa warqad wacan ayaa la yareeyey (haddii fariinta ay ku qoran tahay "Cartesian" iyo "toner" loo yaqaan "spam"), ama suurtagalnimada "toner" oo tilmaamaysa spam waa in dib loo eegaa.
Iyadoo la adeegsanayo farsamadan la-qabsashada, baqshadaha Bayesian waxay ka baran karaan labadoodaba iyo go'aammada isticmaalaha (haddii ay gacanta ku hagaajinayso khalad-galka shaandhada). Isku-xirnaanshaha shaandhada Bayesian sidoo kale waxay hubisaa inay yihiin kuwa ugu wax ku oolka ah isticmaalaha email-ka. Inkastoo spam dadka intooda badani ay leeyihiin sifooyin isku mid ah, boosta sharciyadeed ayaa si kala duwan u kala duwan qof walba.
Sidee Spamiyadu u Heli Karaan Filimada Bayesian?
Noocyada warqadaha sharciyeynta ahi waxay muhiim u yihiin habka loo yaqaan spam filtering ee Bayesian sida spamku yahay. Haddii shaandhada si gaar ah loogu tababbaro qof walba, spammers waxay yeelan doonaan wakhti adag oo ka shaqeeya dadka oo dhan (ama xitaa dadka intooda badan) filimayaasha spam, iyo filtarradu waxay la qabsan karaan wax kasta oo isbaaro isku dayaan.
Spammers waxay kaliya ka dhigi doonaan shaandhada Bayesian si wanaagsan loo tababaray haddii ay fariin u diraan fariinadooda si fiican u ekaa sida email caadiga ah oo qof walba heli karo.
Spammers caadi ahaan ma soo diraan emails caadi ah. Aan u maleyno in tani ay tahay sababtoo ah emayadahaani ma shaqeeyaan sida email ahaan. Sidaa darteed, fursadaha ma ay qabanayaan marka caadiga ah, emails caajisku waa habka kaliya ee ay u sameeyaan filter spam soo dhaafay.
Si kastaba ha ahaatee, haddii spammers ay u wareegaan emailada caadiga ah ee caadiga ah, si kastaba ha ahaatee, waxaynu arki doonaa waxyaabo badan oo spam ah oo ku yaala shabakadayada mar kale, emailkuna wuxuu noqon karaa mid niyad jab ah sida ay ku jireen maalmaha ka horeeya Bayesian (ama xitaa ka sii daran). Waxay sidoo kale burburin doontaa suuqyada noocyada kala duwan ee spamka, inkastoo, sidaas darteedna ma sii socon doonto muddo dheer.
Muujiyeyaasha xooggan waxay noqon karaan Farsameedka Bayerka ee Bayesian & # 39; Achilles & # 39; Caws
Mid ka reeban waxaa loo arki karaa spamerada si ay u shaqeeyaan habka ay u maraan shaashadaha Bayesian xataa iyada oo ay ka kooban yihiin maaddooyinka caadiga ah. Waxaa ku jira nooca Bayesian in hal erey ama sifooyin ay si aad u badan u muuqato in boosteejo wanaagsan ay noqon karto mid aad u muhiim ah si loo soo celiyo fariin kasta oo ka eegaya sida spam in lagu qiimeeyo sida ham by filter.
Haddii spammers ay helayaan hab lagu ogaado ereyadaada saxda ah ee dab-dirka-adigoo isticmaalaya rasiidhada HTML-celiska si aad u aragtid fariimaha aad u furtay, tusaale ahaan, waxay ku dari karaan mid ka mid ah xaashiyaha junkada oo kugu soo gaari kara xataa si wanaagsan, Qalinjabinta Bayesian.
John Graham-Cumming ayaa isku dayey tan isagoo u ogolaanaya laba shaandhayn oo Bayesian ah oo ka shaqeynaya midba midka kale, "xun" midkale oo la qabsashada fariimaha lagu helo in lagu helo "filter" wanaagsan. Waxa uu sheegay in ay shaqeyso, inkastoo nidaamku uu waqti badan yahay oo uu kakan yahay. Uma maleyneyno inaan aragno wax badan oo ka mid ah tani dhaceyso, ugu yaraan ma ahan mid aad u ballaaran, oo aan ku haboonayn sifooyinka emailka shakhsiyaadka. Spammers waxay isku deyi karaan (isku dayaan) in ay qiyaasaan ereyada muhiimka ah ee ururrada (sida "Almaden" qaar ka mid ah dadka ku jira IBM)?
Sida caadiga ah, spam marwalba way ka duwan tahay warqad caadi ah ama ma noqon doonto spam, inkastoo.
Qadka Hoose: Baybalka Bayesian & # 39; Strength Waxay noqon kartaa Tabar darnaansho
Spam filterers Bayesian waa filtarrada ku -salaysan content taas oo:
- waxaa si gaar ah loogu tababbaray in ay aqoonsadaan emailka spammer-ga qofkale iyo fariin wacan , iyaga oo ka dhigaya kuwo aad wax ku ool ah kuna adagtahay inay la qabsadaan lafdhabarta.
- si joogta ah oo aan lahayn dadaal badan ama falanqaynta buuggan la qabsata tabaha ugu dambeeya spammers.
- u qaad khadka emailka shaqsiyadeed ee shakhsi ahaaneed iyo xisaab aad u hooseeya oo muujinaya cillad been abuur ah .
- Nasiib darro, haddii tani ay keento kalsooni indhoole ah oo ku saabsan baqdinta anti-spam ee Bayesian, waxay keeneysaa khalad marmar ah xitaa halis dheeraad ah . Saameynta ka soo horjeeda diidmo been abuur ah (spam oo u muuqda sida boosteejo caadi ah) ayaa leh awood ay ku dhibtoonaan oo ay carqaladeeyaan dadka isticmaala.
