Word Embeddings

Word embeddings are essential for any NLP task. They help in mapping words to vectors in a high-dimensional space where semantically similar words are closer together, thus allowing for better interpretations of text.

Word2Vec

Word2Vec is one of the most popular methods for creating word embeddings. The Polish Word2Vec model was trained on a corpus of 1.5 billion tokens. Here’s how you can load it:

from gensim.models import KeyedVectors
word2vec = KeyedVectors.load('word2vec_100_3_polish.bin')
print(word2vec.similar_by_word('bierut'))

Think of Word2Vec as a neighborhood guide: it categorizes words based on how closely they are related to each other in meaning, much like how neighbors live near each other based on shared interests.

FastText

FastText improves upon Word2Vec by considering subword information. You can load it in a similar manner:

word2vec = KeyedVectors.load('fasttext_100_3_polish.bin')
print(word2vec.similar_by_word('bierut'))

GloVe

Global Vectors for Word Representation (GloVe) can also enhance your vocabulary understanding:

word2vec = KeyedVectors.load_word2vec_format('glove_100_3_polish.txt')
print(word2vec.similar_by_word('bierut'))

Language Models

Language models help predict the next word in a sequence, providing context and understanding. Models like ELMo, RoBERTa, and BART are ideal for tasks such as text generation and classification.

ELMo

Embedding from Language Models (ELMo) generates deep contextual representations. Here is how to utilize it:

from allennlp.commands.elmo import ElmoEmbedder
elmo = ElmoEmbedder(options_file='options.json', weight_file='weights.hdf5')
print(elmo.embed_sentence(['Zażółcić', 'gęślą', 'jaźń']))

RoBERTa

RoBERTa models can be accessed and are highly effective for various Polish NLP tasks.

Text Encoders

Text encoders provide fixed-length vector representations for larger text segments, essential for tasks like semantic search.

Machine Translation Models

These models, including T5 and Marian, are capable of translating between Polish and other languages efficiently.

Fine-Tuned Models

Fine-tuned models, such as ByT5, focus on specific tasks like text correction, making them practical for enhancing your outputs.

Dictionaries and Lexicons

Dictionaries designed for names, places, and other lexical resources can help optimize text understanding.

Models Supporting Polish Language

Resources are available for sentence analysis, machine translation, language models, and more, specifically catering to the Polish language requirements.

Troubleshooting

If you encounter issues during installation or execution of the models, consider the following steps:

• Ensure all dependencies are installed properly.
• Check for version compatibility with your coding environment.
• Refer to the GitHub repositories for any updates or fixes.
