title: the repetitions in Gensim Word2Vec training corpus
body: <p>I am using <code>Gensim</code> to train a <code>Word2Vec</code> embedding on different corpora, pertaining to different years, to compare the embedding vectors.
  My question is: if I repeat the documents of a specific year twice and documents of another year just once, do the resulting embeddings give more weight to the repeated documents?
  I have in my mind to make a corpus that gives more weight to recent documents and less weight to documents from far past.
  I simply train the model on my <code>Line Sentence</code> corpus file.</p>
  <pre><code>Word2Vec(corpus_file=corpus, vector_size=100, window=5, min_count=5, workers=4)
  </code></pre>
