這是我的代碼來計算每個我在裏面輸入的查詢的期限頻率。 現在我正在嘗試爲每個文件添加每個查詢頻率。我如何總計每個文件查詢計數?
輸出示例:
文件的數量是這個文件夾是:11 請輸入查詢: 你怎麼樣 如何 - >這個數字包含這個詞3 是文件 - >這個數字包含這個詞的文件7 你 - >包含該字詞7
字輸入文件的這個數字:你怎麼樣
| File = abc0.txt |
how - >Word count = | 4 |總計數= | 957 |術語頻率= | 0.0042 |
- > IDF = 0.5642714398516419 - > TF/IDF = 0.0023585013159943234
是 - >字數 = | 7 |總計數= | 957 |術語頻率= | 0.0073 |
- > IDF = 0.1962946357308887 - > TF/IDF = 0.00143580193324579
你 - >字數 = | 10 |總計數= | 957 |術語頻率= | 0.0104 |
- > IDF = 0.1962946357308887 - > TF/IDF = 0.002051145618922557
實施例:總頻率爲4 + 7 + 10 = 21 ..
輸入的字:你怎麼樣
| File = abc1.txt |
how - >Word count = | 4 |總計數= | 959 |術語頻率= | 0.0042 |
- > IDF = 0.5642714398516419 - > TF/IDF = 0.0023535826479734803
是 - >字數 = | 7 |總計數= | 959 |術語頻率= | 0.0073 |
- > IDF = 0.1962946357308887 - > TF/IDF = 0.0014328075600794795
你 - >字數 = | 10 |總計數= | 959 |術語頻率= | 0.0104 |
- > IDF = 0.1962946357308887 - > TF/IDF = 0.002046867942970685
我怎樣才能使它以總價3查詢字數爲每個文件?
示例:總頻率爲4 + 7 + 10 = 21 ..

不,這是我面臨的另一個問題,但是,我已經弄清楚了......感謝您的關注。 – 2011-03-15 13:44:03
如果是這樣的話,那麼你真的很難弄清楚你實際上在問什麼。 – 2011-03-15 13:45:53
