這是地球的照片
00:15
It looks very much like the Apollo pictures
1

3093
看起來和廣為人知的阿波羅計劃中
拍到的照片很像
拍到的照片很像
00:18
that are very well known.

看起來和廣為人知的阿波羅計劃中
拍到的照片很像
拍到的照片很像
00:19
There is something different;

2070
但其中有些差異
00:21
you can click on it,
4
9952
1447
你可以點擊它
00:23
and if you click on it,
5
11399
1198
如果你點擊它
00:24
you can zoom in on almost any place on the Earth.
6
12597
3072
你就可以放大地球上的幾乎每個地方
00:27
For instance, this is a bird's-eye view
7
15669
1999
舉例來說，這是洛桑聯邦理工學院的鳥瞰圖
00:29
of the EPFL campus.
8
17668
2666
舉例來說，這是洛桑聯邦理工學院的鳥瞰圖
00:32
In many cases, you can also see
9
20334
2108
很多時候你也可以從旁邊的街上
00:34
how a building looks from a nearby street.
10
22442
3740
看到某棟建築物的的長相
00:38
This is pretty amazing.
11
26182
1422
這真的很神奇
00:39
But there's something missing in this wonderful tour:
12
27604
3427
但這趟美妙的旅程還少了一樣東西：
00:43
It's time.
13
31031
2188
時間
00:45
i'm not really sure when this picture was taken.
14
33219
3070
我不確定這張照片是什麼時候拍的
00:48
I'm not even sure it was taken
15
36289
1412
我甚至無法確定這是在鳥瞰圖的當下拍的
00:49
at the same moment as the bird's-eye view.
16
37701
6083
我甚至無法確定這是在鳥瞰圖的當下拍的
00:55
In my lab, we develop tools
17
43784
2209
在我的實驗室的研發工具
00:57
to travel not only in space
18
45993
1764
不止用在空間的旅行
00:59
but also through time.
19
47757
2558
也用在時間的旅行
01:02
The kind of question we're asking is
20
50315
1870
我們想問的問題是
01:04
Is it possible to build something
21
52185
1393
有辦法做出過往時間的Google Maps嗎？
01:05
like Google Maps of the past?
22
53578
2178
01:07
Can I add a slider on top of Google Maps
23
55756
3310
有辦法在Google Maps上增加一個滑桿
01:11
and just change the year,
24
59066
1803
只要改變年份
01:12
seeing how it was 100 years before,
25
60869
1791
就可以看到100年前
01:14
1,000 years before?
26
62660
1669
1000年前的樣子嗎？
01:16
Is that possible?
27
64329
2123
這可能嗎？
01:18
Can I reconstruct social networks of the past?
28
66452
2252
我能夠重建過去的社群網路嗎？
01:20
Can I make a Facebook of the Middle Ages?
29
68704
3049
我可以建立中世紀時的Facebook嗎？
01:23
So, can I build time machines?
30
71753
3776
我能夠建造時光機嗎？
01:27
Maybe we can just say, "No, it's not possible."
31
75529
2565
我們可以說：「不，這不可能。」
01:30
Or, maybe, we can think of it from an information point of view.
32
78094
3810
或者，我們可以從資訊的角度來看
01:33
This is what I call the information mushroom.
33
81904
3190
我把這個稱之為資訊蘑菇
01:37
Vertically, you have the time.
34
85094
1583
縱軸是時間
01:38
and horizontally, the amount of digital information available.
35
86677
2740
橫軸是我們擁有的數位資訊
01:41
Obviously, in the last 10 years, we have much information.
36
89417
3482
很明顯的，在過去的10年中
我們擁有很大量的資訊
我們擁有很大量的資訊
01:44
And obviously the more we go in the past, the less information we have.
37
92899
3548
也看得出來，越早以前資訊就越少
01:48
If we want to build something like Google Maps of the past,
38
96447
2318
如果我們想建立過去的Google Maps
01:50
or Facebook of the past,
39
98765
1494
或是過去的Facebook
01:52
we need to enlarge this space,
40
100259
1574
我們就必須擴大這個空間
01:53
we need to make that like a rectangle.
41
101833
1938
像是一個長方形
01:55
How do we do that?
42
103771
1510
這要如何做到呢？
01:57
One way is digitization.
43
105281
2098
一個辦法是數位化
01:59
There's a lot of material available --
44
107395
1779
有很多的材料可以用--
02:01
newspaper, printed books, thousands of printed books.
45
109190
6270
報紙、印刷書本
好幾千本印刷書本
我可以把它們全部數位化
02:07
I can digitize all these.
46
115460
1768
02:09
I can extract information from these.
47
117228
2737
我可以從當中截取資訊
02:11
Of course, the more you go in the past,
the less information you will have.
the less information you will have.
48
119965
3543
當然，當時間越往前
你擁有的資訊就越少
你擁有的資訊就越少
02:15
So, it might not be enough.
49
123508
2646
所以，這可能不夠
02:18
So, I can do what historians do.
50
126154
2408
因此，我可以做史學家們做的事
02:20
I can extrapolate.
51
128562
1524
我可以推論
02:22
This is what we call, in computer science, simulation.
52
130086
4470
這就是我們在電腦科學中所稱的模擬
02:26
If I take a log book,
53
134556
1751
如果我有一本航海日誌
02:28
I can consider, it's not just a log book
54
136307
2404
我可以不只把它看成是一位威尼斯船長
特定的航程
特定的航程
02:30
of a Venetian captain going to a particular journey.
55
138711
2972
02:33
I can consider it is actually a log book
56
141683
1643
我可以把它看成是當時許多航程的代表
02:35
which is representative of
many journeys of that period.
many journeys of that period.
57
143326
2582
02:37
I'm extrapolating.
58
145908
2245
我就是在推論
02:40
If I have a painting of a facade,
59
148153
2038
如果我有一幅建築外觀的繪畫
02:42
I can consider it's not just that particular building,
60
150191
2751
我可以不只把它看作特定的一棟建築
02:44
but probably it also shares the same grammar
61
152942
3932
這棟建築可能和其它遺失了資訊的
建築有著相同的風格
建築有著相同的風格
02:48
of buildings where we lost any information.
62
156874
4041
02:52
So if we want to construct a time machine,
63
160915
2858
如果我們想要打造一台時光機
02:55
we need two things.
64
163773
1339
我們需要兩樣東西
02:57
We need very large archives,
65
165112
2234
大量的檔案
02:59
and we need excellent specialists.
66
167346
2742
也需要很厲害的專家
03:02
The Venice Time Machine,
67
170088
1874
威尼斯時光機 (The Venice Time Machine)
03:03
the project I'm going to talk to you about,
68
171962
1805
也就是我接下來要跟你們談論的計劃
03:05
is a joint project between the EPFL
69
173767
3020
這個計劃是由洛桑聯邦理工學院和
威尼斯大學所合作
威尼斯大學所合作
03:08
and the University of Venice Ca'Foscari.
70
176787
2978
03:11
There's something very peculiar about Venice,
71
179765
2165
威尼斯有個特點
03:13
that its administration has been
72
181930
2674
它的管理非常非常的官僚
03:16
very, very bureaucratic.
73
184604
2194
03:18
They've been keeping track of everything,
74
186798
2193
他們持續紀錄了每一件事情
03:20
almost like Google today.
75
188991
2915
就像Google一樣
03:23
At the Archivio di Stato,
76
191906
1514
在政府典藏中心 (Archivio di Stato)
03:25
you have 80 kilometers of archives
77
193420
1764
有長達80公里的檔案
03:27
documenting every aspect
78
195184
2009
記錄了超過1000年來
威尼斯生活的每個面相
威尼斯生活的每個面相
03:29
of the life of Venice over
more than 1,000 years.
more than 1,000 years.
79
197193
2246
03:31
You have every boat that goes out,
80
199439
1920
每一艘出海的船
03:33
every boat that comes in.
81
201359
1076
每一艘返航的船
03:34
You have every change that was made in the city.
82
202435
2797
在這城市裡面的每一個變化
03:37
This is all there.
83
205232
3291
都記錄得一清二楚
03:40
We are setting up a 10-year digitization program
84
208523
3908
我們正建立一個10年的數位化計劃
03:44
which has the objective of transforming
85
212431
1677
要把這個龐大的檔案
轉換成一個巨大的數位系統
轉換成一個巨大的數位系統
03:46
this immense archive
86
214108
1384
03:47
into a giant information system.
87
215492
2426
03:49
The type of objective we want to reach
88
217918
1857
我們想達成的目標是
03:51
is 450 books a day that can be digitized.
89
219775
4726
每天可以數位化450本書
03:56
Of course, when you digitize, that's not enough,
90
224501
2247
當然，只有數位化是不夠的
03:58
because these documents,
91
226748
1287
因為這些文件大部份都是用拉丁、
托斯卡納、威尼斯方言寫的
托斯卡納、威尼斯方言寫的
04:00
most of them are in Latin, in Tuscan,
92
228035
2639
04:02
in Venetian dialect,
93
230689
1515
04:04
so you need to transcribe them,
94
232204
1675
所以有時必須轉錄、翻譯它們
並編成索引
並編成索引
04:05
to translate them in some cases,
95
233879
1681
04:07
to index them,
96
235560
1120
04:08
and this is obviously not easy.
97
236680
2164
而這理所當然並不容易
04:10
In particular, traditional optical
character recognition method
character recognition method
98
238844
3844
特別是當傳統的光學字符識別法
運用在手寫稿上
運用在手寫稿上
04:14
that can be used for printed manuscripts,
99
242688
1424
04:16
they do not work well on the handwritten document.
100
244112
4004
效果不若列印稿的時候
04:20
So the solution is actually to take inspiration
101
248116
2130
解決辦法是借助另外一個方法：語音識別
04:22
from another domain: speech recognition.
102
250246
2901
04:25
This is a domain of something
that seems impossible,
that seems impossible,
103
253147
2055
這個方法看似不可能
但卻是可行的
但卻是可行的
04:27
which can actually be done,
104
255202
2537
04:29
simply by putting additional constraints.
105
257739
2194
只需要加入額外的條件
04:31
If you have a very good model
106
259933
1586
如果你有一個很好的語言模型
曾經被使用過
曾經被使用過
04:33
of a language which is used,
107
261519
1526
04:35
if you have a very good model of a document,
108
263045
2086
如果你有一個很好的文件模型
那它們就已經很完整了
那它們就已經很完整了
04:37
how well they are structured.
109
265131
1432
04:38
And these are administrative documents.
110
266563
1353
而這些是官方文件
很多都非常完整
很多都非常完整
04:39
They are well structured in many cases.
111
267931
2132
04:42
If you divide this huge archive into smaller subsets
112
270063
3308
當你把這巨大的檔案分成許多小子集
04:45
where a smaller subset
actually shares similar features,
actually shares similar features,
113
273371
2877
而每個子集都有共同的特徵的話
04:48
then there's a chance of success.
114
276248
4031
成功的機會就很大
04:54
If we reach that stage, then there's something else:
115
282761
2435
如果我們達到這個階段
就能夠做其他事情：
就能夠做其他事情：
04:57
we can extract from this document events.
116
285196
3522
汲取這個文件中的資訊
05:00
Actually probably 10 billion events
117
288718
2298
事實上這個檔案中大約可以汲取出100億個事件
05:03
can be extracted from this archive.
118
291016
1931
這個巨型資訊系統可以用多種方法搜尋
05:04
And this giant information system
119
292947
1724
05:06
can be searched in many ways.
120
294671
1816
05:08
You can ask questions like,
121
296487
1368
例如，你可以問這樣的問題
05:09
"Who lived in this palazzo in 1323?"
122
297855
2760
「誰在1323年住在這座皇宮裡面？」
05:12
"How much cost a sea bream at the Realto market
123
300615
2222
「1434年時Realto市場裡一條鯛魚多少錢？」
05:14
in 1434?"
124
302837
1724
05:16
"What was the salary
125
304561
1460
「在十年中Murano玻璃工匠的薪水多高？」
05:18
of a glass maker in Murano
126
306021
2045
05:20
maybe over a decade?"
127
308066
1406
05:21
You can ask even bigger questions
128
309472
1422
你也可以問更大的問題
05:22
because it will be semantically coded.
129
310894
2738
因為它是用語意編碼的
05:25
And then what you can do is put that in space,
130
313632
2140
然後你就可以把它放在空間中
05:27
because much of this information is spatial.
131
315772
2173
因為大部份的資訊都是空間性的
05:29
And from that, you can do things like
132
317945
1935
接下來就可以重建這座城市非凡的旅程
05:31
reconstructing this extraordinary journey
133
319880
2113
05:33
of that city that managed to
have a sustainable development
have a sustainable development
134
321993
3356
這座城市設法永續發展超過1000年
05:37
over a thousand years,
135
325349
2126
設法讓時間和環境取得平衡
05:39
managing to have all the time
136
327475
1620
05:41
a form of equilibrium with its environment.
137
329095
2861
05:43
You can reconstruct that journey,
138
331956
1248
你可以重建這趟旅程
05:45
visualize it in many different ways.
139
333204
2896
用不同方法看到它
05:48
But of course, you cannot understand
Venice if you just look at the city.
Venice if you just look at the city.
140
336100
2699
但是當然，如果只是用看的
你無法了解威尼斯
你無法了解威尼斯
05:50
You have to put it in a larger European context.
141
338799
2396
你要把它放到一個更廣大、
歐洲的概念裡面
歐洲的概念裡面
05:53
So the idea is also to document all the things
142
341195
2821
所以這個想法同時也要把檔案
放在歐洲的層級中
放在歐洲的層級中
05:56
that worked at the European level.
143
344016
2423
05:58
We can reconstruct also the journey
144
346439
1964
我們也可以重建威尼斯這個海上帝國的旅程
06:00
of the Venetian maritime empire,
145
348403
1990
06:02
how it progressively controlled the Adriatic Sea,
146
350393
3166
了解它是如何積極地控制亞德里亞海的
06:05
how it became the most powerful medieval empire
147
353559
3746
如何成為中世紀控制了大部分
東方以及南方航線的最強大的帝國
東方以及南方航線的最強大的帝國
06:09
of its time,
148
357305
1561
06:10
controlling most of the sea routes
149
358866
2172
06:13
from the east to the south.
150
361038
2933
06:17
But you can even do other things,
151
365305
2316
你甚至可以做到其它事
06:19
because in these maritime routes,
152
367621
2277
因為這些航線有相似之處
06:21
there are regular patterns.
153
369898
1975
可以更進一步建立模擬系統
06:23
You can go one step beyond
154
371889
2493
06:26
and actually create a simulation system,
155
374382
2120
建立地中海模擬器
06:28
create a Mediterranean simulator
156
376502
2815
06:31
which is capable actually of reconstructing
157
379317
2593
它可以重建我們遺失的資訊
06:33
even the information we are missing,
158
381910
2202
06:36

"If I am in Corfu in June 1323

「如果我在1323年的科孚，想去康士坦丁堡
我要去哪裡搭船？」
我要去哪裡搭船？」
06:45
and want to go to Constantinople,
162
393159
2526
06:47
where can I take a boat?"
163
395685
2143
06:49
Probably we can answer this question

我們或許可以在一天，兩天或三天的
準確度之內回答這個問題
準確度之內回答這個問題

"How much will it cost?"
166

1607
「要花多少錢？」
06:57
"What are the chance of encountering pirates?"
167
405275
3592
「有多大的機率遇到海盜？」
07:00
Of course, you understand,
168
408867
1811
當然，你懂的，這種計劃最大的挑戰
在於修飾、量化
在於修飾、量化
07:02
the central scientific challenge
of a project like this one
of a project like this one
169
410678
2609
07:05
is qualifying, quantifying and representing
170
413287
3729
並在每一步驟重現不確定以及不一致的資料
07:09
uncertainty and inconsistency
at each step of this process.
at each step of this process.
171
417016
3330
07:12
There are errors everywhere,
172
420346
2712
這份文件裡到處都有錯誤
07:15
errors in the document, it's
the wrong name of the captain,
the wrong name of the captain,
173
423058
2489
文件裡的錯誤包括把
船長的名字搞錯了，而有些船根本沒下過水
船長的名字搞錯了，而有些船根本沒下過水
07:17
some of the boats never actually took to sea.
174
425547
3213
07:20
There are errors in translation, interpretative biases,
175
428760
4857
也有翻譯的錯誤，翻譯時的誤解
07:25
and on top of that, if you add algorithmic processes,
176
433624
3466
此外，在用演算法的時候會有辨認上的錯誤
07:29
you're going to have errors in recognition,
177
437090
2949
汲取上的錯誤
07:32
errors in extraction,
178
440039
1961
07:34
so you have very, very uncertain data.
179
442000
4481
所以你會得到相當相當不確定的數據
07:38
So how can we detect and
correct these inconsistencies?
correct these inconsistencies?
180
446481
3757
那我們要如何找到並修正這些不一致之處呢？
07:42
How can we represent that form of uncertainty?
181
450238
3660
我們如何重現不確定性？
07:45
It's difficult. One thing you can do
182
453898
2097
很困難。你可以做的一件事是把每一個步驟建檔
07:47
is document each step of the process,
183
455995
2226
07:50
not only coding the historical information
184
458221
2448
不只是把歷史訊息編碼
07:52
but what we call the meta-historical information,
185
460669
2679
也把所謂的元歷史(meta-history)訊息
07:55
how is historical knowledge constructed,
186
463348
2663
也就是建立歷史知識的根基的每一步都建檔
07:58
documenting each step.
187
466011
1998
08:00
That will not guarantee that we actually converge
188
468009
1645
這沒辦法保證我們確實涵蓋到
威尼斯的每一個故事
威尼斯的每一個故事
08:01
toward a single story of Venice,
189
469654
2450
08:04
but probably we can actually reconstruct
190
472104
2138
但我們確實根據完整文件重建了威尼斯
每一個可能發生過的故事
每一個可能發生過的故事
08:06
a fully documented potential story of Venice.
191
474242
3048
08:09
Maybe there's not a single map.
192
477290
1459
也許地圖不止一幅
08:10
Maybe there are several maps.
193
478749
2120
可能有好幾幅地圖
08:12
The system should allow for that,
194
480869
2216
系統應該要可以到這樣子
08:15
because we have to deal with
a new form of uncertainty,
a new form of uncertainty,
195
483085
2859
因為我們得面對一個新型態的不確定性
08:17
which is really new for this type of giant databases.
196
485944
4641
包含這樣龐大且新穎的資料庫
08:22
And how should we communicate
197
490585
2190
那我們要如何把這個新研究告訴大眾呢？
08:24
this new research to a large audience?
198
492790
3979
08:28
Again, Venice is extraordinary for that.
199
496769
2663
威尼斯是個絕佳的地方
08:31
With the millions of visitors that come every year,
200
499432
2171
由於每年有好幾百萬的遊客
08:33
it's actually one of the best places
201
501603
1763
這裡是試著創造未來博物館最好的地點之一
08:35
to try to invent the museum of the future.
202
503366
2988
08:38
Imagine, horizontally you see the reconstructed map
203
506354
3304
想想，平躺的是建立出的特定年份的地圖
08:41
of a given year,
204
509658
1286
08:42
and vertically, you see the document
205
510944
2958
立著的是用來重建這幅地圖的文件
例如，圖畫
例如，圖畫
08:45
that served the reconstruction,
206
513902
1511
08:47
paintings, for instance.
207
515413
3400
08:50
Imagine an immersive system that permits
208
518813
2580
想像一個讓你彷彿置身於特定年份的
威尼斯的沈浸式系統
威尼斯的沈浸式系統
08:53
to go and dive and reconstruct
the Venice of a given year,
the Venice of a given year,
209
521393
3502
08:56
some experience you could share within a group.
210
524895
2715
一種讓你能和別人分享的經驗
08:59
On the contrary, imagine actually that you start
211
527610
2246
相反的，想像你能夠從一份
威尼斯手稿開始
威尼斯手稿開始
09:01
from a document, a Venetian manuscript,
212
529856
2207
09:04
and you show, actually, what
you can construct out of it,
you can construct out of it,
213
532063
3049
看看你到底能夠從當中建立什麼
09:07
how it is decoded,
214
535112
1772
它是如何被解碼、當中所蘊含的概念是如何重建
09:08
how the context of that document can be recreated.
215
536884
2415
09:11
This is an image from an exhibit
216
539299
1885
這張圖片是現在在日內瓦的展覽當中展出
09:13
which is currently conducted in Geneva
217
541184
2276
09:15
with that type of system.
218
543460
2354
它就是用這類系統所建立的
09:17
So to conclude, we can say that
219
545814
2175
總而言之
09:19
research in the humanities is about to undergo
220
547989
3079
人文研究正走向一場
09:23
an evolution which is maybe similar
221
551068
1802
像是生命科學30年前所經歷的革命
09:24
to what happened to life sciences 30 years ago.
222
552870
4582
09:29
It's really a question of scale.
223
557452
4676
事實上，問題在於它的規模
09:34
We see projects which are
224
562130
3303
我們看到
這些計劃遠超出任何一個
小型研究團隊所能夠做的
小型研究團隊所能夠做的
09:37
much beyond any single research team can do,
225
565433
3843
這在人文領域也很新穎
09:41
and this is really new for the humanities,
226
569276
2243
09:43
which very often take the habit of working
227
571519
3869
人文領域習慣小團隊或是只和數個研究員合作
09:47
in small groups or only with a couple of researchers.
228
575388
4008
09:51
When you visit the Archivio di Stato,
229
579396
2118
當你造訪政府典藏中心時
09:53
you feel this is beyond what any single team can do,
230
581514
2822
你會感覺到這超過任何一個團隊做得到的
09:56
and that should be a joint and common effort.
231
584336
3834
這必須依賴團隊合作
10:00
So what we must do for this paradigm shift
232
588170
3106
在這個典範轉移中
10:03
is actually foster a new generation
233
591276
1902
我們必須培養一些新一代
10:05
of "digital humanists"
234
593178
1537
準備好迎接這個進步的
「數位」人文學家
「數位」人文學家
10:06
that are going to be ready for this shift.
235
594715
2090
10:08
I thank you very much.
236
596805
1959
謝謝

ABOUT THE SPEAKER
Frederic Kaplan - Digital humanities researcherFrederic Kaplan seeks to digitize vast archives of historical information to make maps that move -- through time.
Why you should listen
Frederic Kaplan is the Digital Humanities Chair at Ecole Polytechnique Federale de Lausanne (EPFL) and the EPFL's Digital Humanities Lab Director. Kaplan leads the lab in applying computation to humanities research. His latest project is the Venice Time Machine, a collaborative work archiving 80 kilometers of books from throughout 1000 years of Venetician history. The goal of the time machine is to create an information system which can be searched and mapped. Think of it as a Google Maps for time.
Kaplan holds a PhD in artificial intelligence from the University Paris VI. He lives in Switzerland.
