| Type: | Algolit extension |
| Datasets: | Tristes Tropiques |
| Technique: | calculating semantic similarity with word-embeddings, code inspection |
| Collectively developed by: | The people behind Google Tensorflow's word2vec, Algolit |
This is an annotated version of the basic word2vec script. The code is based on this Word2Vec tutorial provided by Tensorflow.
History
Word2vec consists of related models used to generate vectors from words (also called word embeddings). It is a two-layer neural network, produced by a team of researchers led by Tomas Mikolov at *Google*.
word2vec_basic_algolit.py
The structure of the annotated word2vec script is the following:
- Step 1: Download data.
- Algolit step 1: read data from plain text file
- Algolit inspection: from continuous text to list of words, exported as wordlist.txt.
- Step 2: Create a dictionary and replace rare words with UNK token.
- Algolit inspection: from list of words to a list with the structure [(word, value)], exported as counted.txt.
- Algolit inspection: reversed dictionary, a list of the 5000 (=vocabulary size) most common words, accompanied by an index number.
- Algolit inspection: the object data is created, the original texts where words are replaced with index numbers, exported as data.txt.
- Algolit inspection: list of disregarded words, that fall outside the vocabulary size, exported as disregarded.txt.
- Algolit adaption: reversed version of the initial dataset, where all the disregard words are replaced with UNK (unkown).
- Step 3: Function to generate a training batch for the skip-gram model, exported as reversed-input.txt.
- Algolit inspection: an example of a training batch, a vector with a vector size 128x20.
- Step 4: Build and train a skip-gram model.
- Algolit inspection: a big random matrix is created, with a vector size of 5000x20, exported as big-random-matrix.txt.
- Algolit adaption: select your own set of test words to be previewed during the training proces, using the dictionary.txt
- Step 5: Begin training.
- Algolit inspection: export a training batch of 64 words, with a vector size of 128x20, exported as training-words.txt.
- Algolit inspection: export a the 128 connected window words, one to the left, one to the right, with a vector size of 128x20, exported as training-window-words.txt.
- Algolit adaption: visualisation of the cosine similarity calculation updates.
- Algolit inspection: save training log, exported as logfile.txt
- Step 6: Visualize the embeddings.
- Algolit adaption: select 3 words to be included in the graph and highlighted in red.
Source
The script word2vec_basic.py provides an option to download a dataset from Matt Mahoney's home page. It turns out to be a plain text document, without any punctuation or line breaks.
For the tests that we wanted to do with the script, we decided to work with a piece of academic literature instead: Tristes Tropiques, written by Claude Lévi-Strauss and translated by John Russell. (https://archive.org/details/tristestropiques000177mbp).
Before we could use Lévi-Strauss' text as training material, we needed to remove all the punctuation from the file. To do this, we wrote a small python script text-punctuation-clean-up.py. The script saves a *stripped* version of the original book under another filename.
The book contains 153.003 words in total.
