Notebook ini mengilustrasikan cara mengakses modul Multilingual Sentence Encoder dan menggunakannya untuk kesamaan kalimat di berbagai bahasa. Modul ini merupakan perpanjangan dari modul Universal Encoder asli .

Buku catatan dibagi sebagai berikut:

  • Bagian pertama menampilkan visualisasi kalimat antar pasangan bahasa. Ini adalah latihan yang lebih akademis.
  • Di bagian kedua, kami menunjukkan cara membuat mesin pencari semantik dari sampel korpus Wikipedia dalam berbagai bahasa.

Visualisasikan Kesamaan Teks Antar Bahasa

Dengan penyisipan kalimat sekarang, kita dapat memvisualisasikan kesamaan semantik di berbagai bahasa.

Menghitung Penyematan Teks

Kami pertama-tama mendefinisikan satu set kalimat yang diterjemahkan ke berbagai bahasa secara paralel. Kemudian, kita menghitung embeddings untuk semua kalimat kita.

# Some texts of different lengths in different languages.
arabic_sentences = ['كلب', 'الجراء لطيفة.', 'أستمتع بالمشي لمسافات طويلة على طول الشاطئ مع كلبي.']
chinese_sentences = ['狗', '小狗很好。', '我喜欢和我的狗一起沿着海滩散步。']
english_sentences = ['dog', 'Puppies are nice.', 'I enjoy taking long walks along the beach with my dog.']
french_sentences = ['chien', 'Les chiots sont gentils.', 'J\'aime faire de longues promenades sur la plage avec mon chien.']
german_sentences = ['Hund', 'Welpen sind nett.', 'Ich genieße lange Spaziergänge am Strand entlang mit meinem Hund.']
italian_sentences = ['cane', 'I cuccioli sono carini.', 'Mi piace fare lunghe passeggiate lungo la spiaggia con il mio cane.']
japanese_sentences = ['犬', '子犬はいいです', '私は犬と一緒にビーチを散歩するのが好きです']
korean_sentences = ['개', '강아지가 좋다.', '나는 나의 개와 해변을 따라 길게 산책하는 것을 즐긴다.']
russian_sentences = ['собака', 'Милые щенки.', 'Мне нравится подолгу гулять по пляжу со своей собакой.']
spanish_sentences = ['perro', 'Los cachorros son agradables.', 'Disfruto de dar largos paseos por la playa con mi perro.']

# Multilingual example
multilingual_example = ["Willkommen zu einfachen, aber", "verrassend krachtige", "multilingüe", "compréhension du langage naturel", "модели.", "大家是什么意思" , "보다 중요한", ".اللغة التي يتحدثونها"]
multilingual_example_in_en =  ["Welcome to simple yet", "surprisingly powerful", "multilingual", "natural language understanding", "models.", "What people mean", "matters more than", "the language they speak."]

# Compute embeddings.
ar_result = embed_text(arabic_sentences)
en_result = embed_text(english_sentences)
es_result = embed_text(spanish_sentences)
de_result = embed_text(german_sentences)
fr_result = embed_text(french_sentences)
it_result = embed_text(italian_sentences)
ja_result = embed_text(japanese_sentences)
ko_result = embed_text(korean_sentences)
ru_result = embed_text(russian_sentences)
zh_result = embed_text(chinese_sentences)

multilingual_result = embed_text(multilingual_example)
multilingual_in_en_result = embed_text(multilingual_example_in_en)

Memvisualisasikan Kesamaan

Dengan penyisipan teks di tangan, kita dapat mengambil produk titik mereka untuk memvisualisasikan betapa miripnya kalimat antar bahasa. Warna yang lebih gelap menunjukkan bahwa embeddings secara semantik serupa.

Kesamaan Multibahasa

                     multilingual_example_in_en, multilingual_example,  "Multilingual Universal Sentence Encoder for Semantic Retrieval (Yang et al., 2019)")

Membuat Mesin Pencari Kemiripan Semantik Multibahasa

Sedangkan pada contoh sebelumnya kita memvisualisasikan beberapa kalimat, di bagian ini kita akan membangun indeks pencarian semantik sekitar 200.000 kalimat dari Korpus Wikipedia. Sekitar setengahnya akan dalam bahasa Inggris dan setengah lainnya dalam bahasa Spanyol untuk menunjukkan kemampuan multibahasa dari Encoder Kalimat Universal.

Unduh Data ke Indeks

Pertama, kita akan men-download kalimat berita dalam bahasa kelipatan dari Berita Commentary Corpus [1]. Tanpa kehilangan sifat umum, pendekatan ini juga harus berfungsi untuk mengindeks bahasa lain yang didukung.

Untuk mempercepat demo, kami membatasi hingga 1000 kalimat per bahasa.

    ('ru', 'en-ru.txt.zip', 'News-Commentary.en-ru.ru', 'Russian'),
    ('es', 'en-es.txt.zip', 'News-Commentary.en-es.es', 'Spanish'),

  language_to_sentences[language_code] = pd.read_csv(news_path, sep='\t', header=None)[0][:1000]

Verifikasi bahwa mesin pencari kesamaan semantik berfungsi

Pada bagian ini kami akan mendemonstrasikan:

  1. Kemampuan pencarian semantik: mengambil kalimat dari korpus yang secara semantik mirip dengan kueri yang diberikan.
  2. Kemampuan multibahasa: melakukannya dalam beberapa bahasa saat mereka menanyakan bahasa dan bahasa indeks cocok
  3. Kemampuan lintas bahasa: mengeluarkan kueri dalam bahasa yang berbeda dari korpus yang diindeks
  4. Korpus bahasa campuran: semua hal di atas pada satu indeks yang berisi entri dari semua bahasa

Kemampuan lintas bahasa pencarian semantik

Di bagian ini kami menunjukkan cara mengambil kalimat yang terkait dengan kumpulan contoh kalimat bahasa Inggris. Hal-hal untuk dicoba:

  • Coba beberapa contoh kalimat yang berbeda
  • Coba ubah jumlah hasil yang dikembalikan (dikembalikan dalam urutan kesamaan)
  • Cobalah kemampuan lintas-bahasa dengan kembali hasil dalam bahasa yang berbeda (mungkin ingin menggunakan Google Translate pada beberapa hasil ke bahasa asli Anda untuk cek kewarasan)

Kami menawarkan variasi model Universal Encoder yang dioptimalkan untuk berbagai hal seperti memori, latensi, dan/atau kualitas. Silakan bereksperimen dengan mereka untuk menemukan yang cocok.

Perpustakaan tetangga terdekat

Kami menggunakan Annoy untuk mencari tetangga terdekat secara efisien. Lihat bagian pengorbanan untuk membaca tentang jumlah pohon (memori tergantung) dan jumlah item untuk mencari (latency-dependent) --- SimpleNeighbors hanya memungkinkan untuk mengontrol jumlah pohon, tetapi refactoring kode untuk penggunaan mengganggu secara langsung harus sederhana, kami hanya ingin membuat kode ini sesederhana mungkin untuk pengguna umum.

Jika mengganggu tidak skala untuk aplikasi Anda, silakan juga memeriksa Faiss .

Semua yang terbaik membangun aplikasi semantik multibahasa Anda!
