00:00:06,070 --> 00:00:07,120
Salom, mening ismim Jon.

2
00:00:07,510 --> 00:00:10,140
Men Googleda qidiruv va mashinalarni o'rganish
bo'yicha guruhlarga rahbarlik qilaman.

3
00:00:12,130 --> 00:00:14,230
Menimcha, butun dunyodagi odamlar ahamiyatsiz

4
00:00:14,230 --> 00:00:16,214
va yoki nihoyatda muhim savollar berish uchun

5
00:00:16,215 --> 00:00:19,160
qidiruv tizimlariga

6
00:00:19,160 --> 00:00:20,930
murojaat qilishlari hayratlanarli darajada qiziq.

7
00:00:20,930 --> 00:00:23,450
Shuning uchun ularga eng yaxshi javoblarni berish

8
00:00:23,450 --> 00:00:24,864
juda katta mas'uliyatdir.

9
00:00:26,710 --> 00:00:30,610
Salom, mening ismim Akshaya va men Bing 
qidiruv tizimi guruhida ishlayman.

10
00:00:30,910 --> 00:00:33,190
Biz sun'iy intellekt va mashinani

11
00:00:33,190 --> 00:00:35,800
o'rganishni ko'p marotaba boshlashimiz mumkin,

12
00:00:35,830 --> 00:00:39,010
ammo foydalanuvchilar undan foydalanishi uchun

13
00:00:39,140 --> 00:00:42,390
qaror qabul qilishimiz kerak,
chunki oxiri baribir jamiyatga ta'sir o'tkazishni xohlaymiz.

14
00:00:43,780 --> 00:00:45,400
Keling, oddiy savol beraylik.

15
00:00:45,820 --> 00:00:48,070
Marsga sayohat qilish uchun qancha vaqt ketadi?

16
00:00:49,330 --> 00:00:50,950
Bu natijalar qayerda kelib chiqgan

17
00:00:51,370 --> 00:00:54,100
va nega birinchisidan oldin ro'yxatga olingan?

18
00:00:55,700 --> 00:00:58,150
Xo'sh, keling chuqurlashamiz va qidiruv tizimi

19
00:00:58,150 --> 00:00:59,860
sizning so'rovingizni va natijangizni nimaga aylantirganini
ko'rib chiqamiz.

20
00:01:00,690 --> 00:01:03,360
Siz bilishingiz kerak bo'lgan narsa shundan iboratki,

21
00:01:03,430 --> 00:01:06,480
siz qidiruvni amalga oshirganingizda, qidiruv tizimi haqiqatan

22
00:01:06,480 --> 00:01:08,010
real vaqtda qidirish uchun butun dunyo bo'ylab veb-saytga chiqmaydi.

23
00:01:08,140 --> 00:01:10,610
Buning sababi, Internetda milliarddan ziyod 

24
00:01:10,610 --> 00:01:14,140
veb-saytlar mavjud va har daqiqa yuzlab veb-saytlar yaratilmoqda.

25
00:01:14,140 --> 00:01:16,210
Qidiruv tizimi kerakli saytni topishi uchun

26
00:01:16,240 --> 00:01:18,690
har bir saytni bosib o'tishi kerak bo'lsa,

27
00:01:18,690 --> 00:01:20,120
bu abadiy davom etardi.

28
00:01:20,500 --> 00:01:21,940
Shuning uchun qidiruvni tezlashtirish uchun,

29
00:01:21,970 --> 00:01:24,940
qidiruv tizimlari keyinchalik qidirishingizga yordam 

30
00:01:25,420 --> 00:01:28,560
berishi mumkin bo'lgan ma'lumotlarni yozib olish 
uchun doimiy ravishda Internetni skanerlashadi.

31
00:01:28,930 --> 00:01:31,270
Shunday qilib, siz Mars sayohatini qidirayotganingizda

32
00:01:31,630 --> 00:01:33,700
qidiruv tizimida sizga

33
00:01:33,700 --> 00:01:35,728
real vaqtda javob berish uchun kerak
bo'lgan narsalarni berishi kerak.

34
00:01:36,250 --> 00:01:37,540
Mana bu qanday ishlaydi.

35
00:01:37,900 --> 00:01:42,010
Internet bir-biriga giperlinklar
orqali bog'langan veb-sahifadir.

36
00:01:42,400 --> 00:01:44,680
Qidiruv tizimlari doimiy ravishda

37
00:01:44,680 --> 00:01:47,380
veb-sahifalardan ular haqida
ma'lumot to'plash uchun 

38
00:01:47,380 --> 00:01:49,040
Spider deb nomlangan dasturdan foydalanadilar.

39
00:01:49,780 --> 00:01:51,550
U har gal giperlinkni topganda,

40
00:01:52,090 --> 00:01:55,000
Internet bo'ylab topadigan har bir

41
00:01:55,030 --> 00:01:57,240
sahifasiga kirguniga qadar unga amal qiladi.

42
00:01:57,335 --> 00:01:59,170
Spider tashrif buyurgan,

43
00:01:59,200 --> 00:02:02,320
har bir sahifa uchun qidiruv indekslari deb nomlangan

44
00:02:02,500 --> 00:02:05,650
maxsus ma'lumotlar bazasiga qo'shib qidirish uchun
kerak bo'lgan ma'lumotlarni yozib oladi.

45
00:02:07,166 --> 00:02:09,530
Keling, avvalgi qidiruvga qaytamiz

46
00:02:09,590 --> 00:02:11,990
va tizimning natijalarini

47
00:02:11,990 --> 00:02:13,333
qanday qaytarganligini bilib olamiz.

48
00:02:13,640 --> 00:02:16,460
Marsga qancha vaqt ketishini so'raganingizda,

49
00:02:16,640 --> 00:02:18,860
qidiruv tizimi ushbu so'zlarni o'z ichiga olgan Internetdagi

50
00:02:18,920 --> 00:02:21,410
barcha sahifalar ro'yxatini darxol

51
00:02:21,410 --> 00:02:24,500
olish uchun qidiruv indeksidagi so'zlarning
har biriga qarab chiqadi.

52
00:02:24,890 --> 00:02:26,870
Ammo qidiruv so'zlarni qidirib

53
00:02:26,870 --> 00:02:28,760
topishi millionlab sahifalarni qaytarishi mumkin,

54
00:02:28,760 --> 00:02:31,110
shuning uchun qidiruv tizimi sizni

55
00:02:31,110 --> 00:02:33,120
birinchi natijangizni ko'rsatishi uchun
eng yaxshi mosliklarni aniqlay olishi kerak.

56
00:02:33,340 --> 00:02:36,010
Bu juda qiyin bo'ladi, chunki qidiruv tizimida

57
00:02:36,010 --> 00:02:38,040
nima qidirayotganingizni taxmin
qilish kerak bo'lishi mumkin.

58
00:02:38,930 --> 00:02:41,360
Har bir qidiruv tizimi o'z algoritmidan foydalanib,

59
00:02:41,360 --> 00:02:44,230
sahifalarni siz xohlagan narsaga
qarab saralashga imkon beradi.

60
00:02:44,930 --> 00:02:47,660
Qidiruv tizimining reyting algoritmi

61
00:02:47,990 --> 00:02:50,360
sizning qidiruv so'zingiz sahifa sarlavhasida
ko'rinishni tekshirishi mumkin,

62
00:02:50,900 --> 00:02:53,820
barcha so'zlar bir-birining yonida ko'rinishini
tekshirishi mumkin,

63
00:02:54,520 --> 00:02:57,020
yoki uni aniqlashga yordam beradigan

64
00:02:57,020 --> 00:02:58,610
boshqa har qanday hisob-kitoblar,

65
00:02:58,670 --> 00:03:01,420
qaysi sahifalarni ko'rishingiz va 
qaysi birini ko'rmaslikni tekshirishi mumkin.

66
00:03:02,960 --> 00:03:04,960
Google eng munosib qidiruv natijalarini tanlash bo'yicha

67
00:03:04,960 --> 00:03:08,530
joriy sahifaga qancha veb-sahifalar
bog'langanligiga oid

68
00:03:08,560 --> 00:03:11,230
eng mashhur algoritmni ishlab chiqdi.

69
00:03:11,830 --> 00:03:14,140
Ushbu g'oya shundan iboratki,

70
00:03:14,140 --> 00:03:15,660
agar ko'plab veb-saytlar sahifani qiziqarli deb hisoblasa,

71
00:03:15,660 --> 00:03:17,940
ehtimol bu siz izlayotgan narsa bo'lishi mumkin.

72
00:03:18,190 --> 00:03:20,020
Ushbu algoritm veb-sahifalarni reytingi uchun emas,

73
00:03:20,590 --> 00:03:22,330
balki Google ga asos solgan,

74
00:03:22,570 --> 00:03:25,210
ixtirochi Larry Page nomi bilan berilganligi uchun,

75
00:03:25,480 --> 00:03:27,333
sahifalar reytingi deb ataladi.

76
00:03:27,940 --> 00:03:30,520
Veb-saytga tez-tez tashrif buyurganingizda pul 
ishlab topganligi sababli,

77
00:03:30,820 --> 00:03:32,950
spammerlar doimiy ravishda qidiruv
algoritmini chetlab o'tishning

78
00:03:32,950 --> 00:03:35,741
yo'llarini qidirmoqdalar,

79
00:03:35,742 --> 00:03:37,931
natijada ularning sahifalari yuqoriroq bo'lib ko'rinadi.

80
00:03:38,260 --> 00:03:40,750
Qidiruv tizimlari soxta yoki ishonchsiz saytlarni
yuqori darajaga chiqishiga yo'l qoymaslik uchun

81
00:03:40,750 --> 00:03:44,296
o'zlarining algoritmlarini muntazam
ravishda yangilab turishadi.

82
00:03:44,680 --> 00:03:47,350
Oxir oqibat, ushbu ishonchsiz sahifalarni
veb-manziliga qarab

83
00:03:47,500 --> 00:03:49,450
va uni ishonchli manba

84
00:03:49,690 --> 00:03:52,990
ekanligini tekshirib turishingiz kerak.

85
00:03:53,680 --> 00:03:55,390
Algoritmlarni takomillashtirish uchun ular

86
00:03:55,420 --> 00:03:58,420
raqobatchilariga qaraganda

87
00:03:58,540 --> 00:04:00,460
yaxshi va tez natijalar beradi.

88
00:04:01,000 --> 00:04:03,100
Zamonaviy qidiruv tizimlari

89
00:04:03,100 --> 00:04:06,820
qisqartirishga yordam berishi uchun aniq berilmagan
ma'lumotlardan ham foydalanadi.

90
00:04:07,150 --> 00:04:10,120
Masalan, agar siz kuchuklar parkiga bog'larni qidirsangiz,

91
00:04:10,240 --> 00:04:12,190
ko'plab qidiruv tizimlari sizga 

92
00:04:12,190 --> 00:04:13,840
hatto siz joylashuvingizni kiritmagan bo'lsangiz ham.

93
00:04:14,080 --> 00:04:16,260
yaqin atrofdagi barcha kuchuk parklarni natijalarini beradi.

94
00:04:17,800 --> 00:04:20,530
Zamonaviy qidirish bo'yicha muhandislar
nafaqat sahifadagi so'zlarni,

95
00:04:20,530 --> 00:04:22,060
balki ular qidirayotgan narsaga mos keladigan,

96
00:04:22,300 --> 00:04:24,970
eng yaxshisini topish uchun

97
00:04:24,970 --> 00:04:26,750
aslida nimani anglatishini tushunishadi.

98
00:04:27,130 --> 00:04:29,980
Masalan, siz tezkor suv ichish idishini qidirsangiz,

99
00:04:30,280 --> 00:04:32,300
u sportchi uchun izlayotganini bilib oladi.

100
00:04:32,500 --> 00:04:34,450
Agar siz katta suv ichish idishini qidirsangiz,

101
00:04:34,450 --> 00:04:36,730
u sizga oshxonangiz uchun variantlarni topadi.

102
00:04:38,420 --> 00:04:41,910
So'zlarni yaxshiroq tushinish uchun
biz sun'iy intelllektning bir turi deb nomlangan,

103
00:04:41,910 --> 00:04:43,985
mashinasozlikdan foydalanamiz.

104
00:04:43,985 --> 00:04:46,050
Bu qidiruv algoritmlariga sahifadagi

105
00:04:46,090 --> 00:04:48,400
so'zlarning alohida harflarini emas,

106
00:04:48,400 --> 00:04:51,280
balki so'zlarning asosiy ma'nosini
ham tushinishga imkon beradi.

107
00:04:53,690 --> 00:04:55,850
Internet su'ratlar bilan tez o'sib bormoqda,

108
00:04:56,210 --> 00:04:59,810
agar qidiruv tizimlarini ishlab chiqaradigan jamoalar
bizning vazifamizni to'g'ri bajaradigan bo'lsa,

109
00:05:00,080 --> 00:05:04,090
siz istagan ma'lumotlar har doim bir necha
marta bosilishi kerak, xolos.
