gensim Topic Modelling in Python
==================================

Gensim is a Python library for *topic modelling*, *document indexing*
and *similarity retrieval* with large corpora. Target audience is the
*natural language processing* (NLP) and *information retrieval* (IR)
community.
Features
--------
- All algorithms are **memory-independent** w.r.t. the corpus size
(can process input larger than RAM, streamed, out-of-core),
- **Intuitive interfaces**
- easy to plug in your own input corpus/datastream (trivial
streaming API)
- easy to extend with other Vector Space algorithms (trivial
transformation API)
- Efficient multicore implementations of popular algorithms, such as
online **Latent Semantic Analysis (LSA/LSI/SVD)**, **Latent
Dirichlet Allocation (LDA)**, **Random Projections (RP)**,
**Hierarchical Dirichlet Process (HDP)** or **word2vec deep
learning**.
- **Distributed computing**: can run *Latent Semantic Analysis* and
*Latent Dirichlet Allocation* on a cluster of computers.
- Extensive [documentation and Jupyter Notebook tutorials].
If this feature list left you scratching your head, you can first read
more about the [Vector Space Model] and [unsupervised document analysis]
on Wikipedia.
Installation
------------
This software depends on [NumPy and Scipy], two Python packages for
scientific computing. You must have them installed prior to installing
gensim.
It is also recommended you install a fast BLAS library before installing
NumPy. This is optional, but using an optimized BLAS such as [ATLAS] or
[OpenBLAS] is known to improve performance by as much as an order of
magnitude. On OS X, NumPy picks up the BLAS that comes with it
automatically, so you dont need to do anything special.
Install the latest version of gensim:
```bash
pip install --upgrade gensim
```
Or, if you have instead downloaded and unzipped the [source tar.gz]
package:
```bash
python setup.py install
```
For alternative modes of installation, see the [documentation].
Gensim is being [continuously tested](https://travis-ci.org/RaRe-Technologies/gensim) under Python 3.6, 3.7 and 3.8.
Support for Python 2.7 was dropped in gensim 4.0.0 install gensim 3.8.3 if you must use Python 2.7.
How come gensim is so fast and memory efficient? Isnt it pure Python, and isnt Python slow and greedy?
--------------------------------------------------------------------------------------------------------
Many scientific algorithms can be expressed in terms of large matrix
operations (see the BLAS note above). Gensim taps into these low-level
BLAS libraries, by means of its dependency on NumPy. So while
gensim-the-top-level-code is pure Python, it actually executes highly
optimized Fortran/C under the hood, including multithreading (if your
BLAS is so configured).
Memory-wise, gensim makes heavy use of Pythons built-in generators and
iterators for streamed data processing. Memory efficiency was one of
gensims [design goals], and is a central feature of gensim, rather than
something bolted on as an afterthought.
