Alat Penapisan Kesamaan Nama Fail Teks

Kumpulkan fail TXT/HTML berdasarkan persamaan nama fail, dan kekalkan fail ideal dalam setiap kumpulan secara automatik berdasarkan metrik kandungan seperti bilangan perkataan dan ayat untuk penyahduaan yang cekap.

Penggunaan Alat

Kembali ke versi lama

Petua pemprosesan:Sahkan ambang persamaan, algoritma dan peraturan simpan dalam “Tetapan penapis” sebelum mula menapis. Fail hanya dibaca dan dibungkus pada halaman ini, tidak perlu dimuat naik ke pelayan.

1Peraturan kumpulan

Ambang persamaan nama fail

76%

Nilai lebih tinggi bermakna nama fail perlu lebih hampir untuk masuk kumpulan sama.

Algoritma persamaan

Algoritma gabungan sesuai untuk nama fail campuran Cina, Inggeris dan bernombor.

Kaedah kumpulan

Kumpulan rantaian lebih longgar, kumpulan fail wakil lebih stabil.

2Peraturan simpan

Asas simpan dalam kumpulan

Metrik hanya dibandingkan dalam kumpulan serupa dan tidak mengubah fail asal.

Kendalian seri

Digunakan apabila skor asas simpan sama.

Fail kandungan kosong

Sesuai untuk mengecualikan fail pemegang tempat yang teksnya kosong selepas dibaca.

3Baca & normalkan

Pengekodan teks

Kesan auto mengutamakan BOM dan pengekodan Cina biasa.

Nama fail ZIP

Biarkan kosong untuk guna nama fail lalai.

Baris pratonton hasil

Hanya mempengaruhi paparan halaman, bukan hasil pakej.

Abaikan sambungan semasa banding Abaikan huruf besar/kecil Seragamkan ruang, sengkang & tanda baca Kurangkan penanda salinan, copy, versi Kumpulkan terus jika teks sama tepat Lampirkan laporan CSV dan JSON dalam ZIP

Arahan

Arahan Penggunaan Perisian

Pilih fail atau muatkan contoh:Klik “Pilih fail” untuk memilih fail teks seperti .txt, .html, .htm secara pukal, atau gunakan data contoh untuk menguji dahulu. Halaman hanya mempratonton 20 fail pertama; semua fail akan dikira semasa pemprosesan.
Tetapkan pengumpulan keserupaan:
- Ambang keserupaan:Semakin tinggi nilainya, semakin hampir nama fail perlu untuk dimasukkan ke dalam kumpulan yang sama.
- Algoritma keserupaan:Anda boleh memilih algoritma gabungan, jarak suntingan Levenshtein, nisbah padanan berturutan, Jaccard, atau kosinus kekerapan aksara.
- Kaedah pengumpulan:Pengumpulan rantaian serupa sesuai untuk fail dengan perubahan versi berterusan; pengumpulan fail wakil sesuai untuk menyusun fail berdasarkan nama rujukan.
Pilih asas pengekalan:Fail yang dikekalkan dalam kumpulan boleh ditentukan berdasarkan skor kualiti kandungan gabungan, bilangan aksara teks biasa, bilangan perkataan, bilangan ayat, purata panjang ayat, peratusan nombor, peratusan tag HTML atau saiz fail.
Konfigurasi bacaan dan output:Anda boleh menetapkan pengekodan teks, nama fail ZIP, bilangan baris pratonton, serta memilih sama ada mengabaikan sambungan fail, huruf besar/kecil, tanda salinan, tanda nombor versi, dan sama ada melampirkan laporan CSV dan JSON dalam ZIP.
Mulakan penapisan:Selepas mengklik “Mulakan penapisan”, alat akan membaca fail, mengekstrak kandungan utama, mengira keserupaan nama fail, menjana kumpulan dan mengekalkan fail mengikut peraturan.
Lihat dan muat turun:Selepas pemprosesan selesai, anda boleh melihat pratonton kumpulan, pratonton fail yang ditapis dan log pemprosesan. Klik “Muat turun fail yang dikekalkan ZIP” untuk mendapatkan hasilnya. Jika terdapat fail dengan nama yang sama dalam hasil, nombor akan ditambahkan pada hujung nama fail untuk membezakannya.

Soalan Lazim

J: Disarankan bermula dengan ambang lalai untuk ujian. Apabila ambang lebih tinggi, hanya fail dengan nama yang hampir sama akan dikumpulkan; apabila ambang lebih rendah, fail dengan perbezaan nama yang lebih besar juga mungkin masuk ke dalam kumpulan yang sama. Anda boleh menggunakan “Pratonton kumpulan” dahulu untuk melihat kesannya sebelum melakukan penapisan rasmi.

J: Levenshtein terutamanya mengukur jarak suntingan nama fail, sesuai untuk fail dengan perubahan nama yang kecil; algoritma gabungan pula menggabungkan jarak suntingan, padanan berturutan, set aksara dan kekerapan aksara, menjadikannya lebih fleksibel untuk nama fail yang mencampurkan bahasa Cina, bahasa Inggeris, nombor siri dan tanda salinan.

Jawapan: Ini adalah untuk memastikan paparan halaman kekal kemas dan operasi berjalan lancar. Bilangan pratonton tidak akan menjejaskan skop pemprosesan; semua fail yang dipilih secara pukal akan disertakan dalam pengiraan kesamaan dan pembungkusan ZIP.

Jawapan: Fail yang dikekalkan akan cuba menggunakan nama fail asal. Jika terdapat fail dengan nama yang sama dalam ZIP, sistem akan menambah nombor selepas nama fail asal, contohnya 文章_2.txt, untuk mengelakkan penindihan.

Jawapan: Fail HTML akan mengekstrak kandungan teks yang kelihatan terlebih dahulu dan membuang kandungan seperti skrip dan gaya, kemudian mengira metrik seperti bilangan aksara, bilangan perkataan dan bilangan ayat. Laporan juga akan merekodkan peratusan tag HTML untuk memudahkan penilaian kepadatan kandungan halaman.

Jawapan: Tidak. Pembacaan fail, statistik kandungan, pengelompokan kesamaan dan pembungkusan ZIP semuanya dilakukan pada halaman setempat; pelayan tidak akan menerima kandungan fail anda.

Jawapan: Tidak. Fail asal tidak akan dipindahkan, dinamakan semula atau dipadamkan. Penapisan hanya menentukan fail mana yang dimasukkan ke dalam pakej hasil muat turun; fail yang tidak dikekalkan akan disenaraikan dalam laporan dan pratonton halaman.
