# EarningsCall2Vec
This is a [fastText](https://fasttext.cc/) model trained via [`Gensim`](https://radimrehurek.com/gensim/): It maps each token in the vocabulary (i.e., unigram and frequently coocurring bi-, tri-, and fourgrams) to a dense, 300-dimensional vector space, designed for performing **semantic search**. It has been trained on corpus of ~160k earning call transcripts, in particular the executive remarks within the Q&A-section of these transcripts (13m sentences).

## Usage (API)
```
pip install -U xxx
```
Then you can use the model like this:
```python
py code
```

## Usage (Gensim)

## Background

Context on the project. 


## Intended Uses

Our model is intented to be used for semantic search on a token-level: It encodes search-queries (i.e., token) in a dense vector space and finds semantic neighbours, i.e., token which frequently occur within similar contexts in the underlying training data. Note that this search is only feasible for individual token and may produce deficient results in the case of out-of-vocabulary token.


## Training procedure

```python
logging.basicConfig(format='%(asctime)s : %(levelname)s : %(message)s', level=logging.INFO)

# init
model = FastText(
    vector_size=300,
    window=5,
    min_count=10,
    alpha=0.025,
    negative = 5,
    seed=2021,
    sample = 0.001,
    sg=1,
    hs=0,
    max_vocab_size=None,
    workers=10,
)

# build vocab
model.build_vocab(corpus_iterable=LineSentence(<PATH_TRAIN_DATA>))

# train model
model.train(
    corpus_iterable=LineSentence(<PATH_TRAIN_DATA>),
    total_words=model.corpus_total_words,
    total_examples=model.corpus_count,
    epochs=50,
)

# save to binary format
save_facebook_model(<PATH_MOD_SAVE>)
```
