　前回のエントリで紹介したように文書のテキスト解析に特化したGoogle Cloud Vison APIの”DOCUMENT_TEXT_DETECTION”に日本語がまだ対応していないため、英語の文書で試してみました。今回は2つの英語の文書について、以下をそれぞれ試しました。

　今回、”DOCUMENT_TEXT_DETECTION”で使用したスクリプト（kekiさんがQitaで公開したocr.php）の一部を以下のように修正したものを使用しました。

"features" => array(
   array(
    "type" => "DOCUMENT_TEXT_DETECTION",
    "maxResults" => 10,
    ),
),
"imageContext" => array(
  "languageHints" => array("en"),
),

結論から申せば、Googleドライブを使ったほうだ断然よい、というか、”DOCUMENT_TEXT_DETECTION”のほうの結果が、”TEXT_DETECTION”とほとんど変わらないというか、単純に”TEXT_DETECTION”を”DOCUMENT_TEXT_DETECTION”を置き換えて、英語に言語指定するだけではだめなのか、APIの投げ方に問題がなかったか検証が必要そうです。

Phase Analysis of the Twentieth Air Force Strategic Mining Blockade of the Japanese Empire
SECTION A-OVERAL PLANNING
The Mission
The In1n ing mission was to complet e the de struction of the Japanese shipborne lines of communication. The three principal objectives were:
l. To prevent the importation of raw materials and food into Japan.
2. To prevent the supply and deployment of her military forces.
3. To disrupt her internal marine transportatilon wl thin the Inland Se8 .
It was belie ved that the mining, if carried out, in force, would terminate practically all imports into Japan; first of raw materials, finally of food. As a result, enemy industry would be starved for materials and eventually cease production, and the enemy population would be reduced to starvation. The effect of starvation would combine with the incendiary raids to reduce the civilian will to wage war. Therefore, the operation was called ST.RVATION.
The Torget
When the mining campaign began, the enemy had approximately 2,000,000 gt of shipping of looC) gt or Over 8a fall Oat This shipping passed freely through Shimonoseki Straits into the Sea of Japan and the Yellow Sea, as well as to the southern areas conque red by the Japanese, via the Straits of Formosa. Very little Japanese shipping was able to challenge the mastery of the American submarines in Pacific waters, but on the other hand, enemy minefields and escorts, as well as air patrols, prevented any effective utilization of our forces against the shipping in the Japanese Inner Zone. The amount of shipping and the routes were adequate at the beginning of the year to supply the enemy’s needs in the Inner Zone.
It is estinated that foods and raw na terials were moving into Japan at a rate of from l,000,000 to l , 500 000 tons per month. There were numerous indications that, whatever the shipping requirements were, Japan’s shipping position was approaching a marginal point, and that any further substantial re
duction in either the number or IOOvement of availsable vessels would Strike a severe blow to the Japanese war economy.
The mining was to be of a strategic nature, and was to supplement the strategic bombing of Japan. The estimates which follow show the importance of waterborne freight to the Japanese.
During l?44 the following percentages of imports required by Japanese industries were sea borne:
l. 80 percent of all oil supplies.
2. 88 percent of all iron (iron ore and in
gots).
3. 24 percent of all coal ( including 90 percent coking coal).
4. 20 percent of all food.
As regards food alone, in Japan were such that the percent was the ence and tion.

Inside the Japanese Home laters, the Inland Sea forms a natural freight shipping route, well prote cted and free from the overland obstacle S of terrain which have prevented the development of extensive railroads and motor transportation facilities. As a result, 75 percent of all transportation was waterborne, including 57 percent of all the coal used. One-half of the power used in the great indus trial regions of Kobe-Osaka, Nagoya, and Tokyo was obtained from waterborne Coal.
The number of Japan ese ships available had been greatly reduced by our submarine warfare, but the remaining shipping, for the time being, was invulnere ble to our Submarine attacks be cause it w2s Operating in the Inner Zone, and was protected by extensive minefields, difficult to penetrate.
The Japanese mer chant fleet position as of 27 ..arch 45 was as follows for steel ships of loC0 gt and Over:

fore than 60 percent of the tonnage of this shipping was composed of ships with a size of 4000 gross tons or larger. These large ships were the prime targets, and one of the mining problems was to sink ships selectively. One mine could sink or seriously damage one lo,000 ton ship at ten times the profit that would be obtained if the same mine sank or damaged one l000 ton ship.
The Shipping, necessary to support the faltering enemy war industry each year required approximately l2,000 passages from Chinese and Korean ports via Shimonoseki Straits, approxima tel y l2,000 local voyages between In) and Sea ports, and l3,000 voyages to the Kobe-Osaka region. As the enemy attempted to disperse industries, a move made necessary by the strategic bombing of Japan by the Twentieth Air Force, his transportation requirements increased markedly. Since his railroads and motor facilities were already strained to the maximum, this had to be effected largely by sea transportation. Furthermore, the destruction of his stockpiles by in cendiary and bombing raids required an abnormal transfer of raw materials between different regions. In particular, the transfer of his fuel supplies, which were stored in a few regions, could be greatly disorganized by strategic mine warfare. Because the flow of oil and aviation gas from his sources in the South had been reduced, such a disorganization would further seriously affect his war industry.
Plate I (page 20 ) represents schematically the railroad routes of Japan and indicates the ports served by railroads which might be used for diversinary ports.
