Genderizer
======================

Genderizer is a language independent module which tries to detect gender by looking at given first names and/or
analyzing sample texts.

##Installation
You can install this package using the following ```pip``` command:

```sh
$ sudo pip install genderizer3
```

##Examples

```python
from genderizer3.genderizer3 import Genderizer

print(Genderizer.detect(firstName='John'))
# >>> male

print(Genderizer.detect(firstName='Marry'))
# >>> female

print(Genderizer.detect(firstName='mustafa'))
# >>> male

print(Genderizer.detect(firstName='fatma'))
# >>> female

print(Genderizer.detect(firstName='fikret'))
# >>> None

print(Genderizer.detect(firstName='fikret', text='galatasary maÃ§Ä± kaÃ§maz'))
# >>> male

print(Genderizer.detect(firstName='fikret', text='annemlerle yemek yedik'))
# >>> female

print(Genderizer.detect(text='askerlik yoklamasÄ±nÄ± kaÃ§Ä±rdÄ±m mk'))
# >>> male

print(Genderizer.detect(text='bana Ã§iÃ§ek alan erkek iÃ§in canÄ±m feda'))
# >>> female

print(Genderizer.detect(firstName='fatma', text='askerlik yoklamasÄ±nÄ± kaÃ§Ä±rdÄ±m mk'))
# >>> female

print(Genderizer.detect(text='futbol sevgi'))
# >>> None

print(Genderizer.detect(text='lan bi siktir git'))
# >>> male

```

***Note***: You may claim that women can say ```lan bi siktir git```, of course. But the probability of being female is
less than the probability of being male according to the trained data of the classifier.

So it is obvious that the success of detection depends on the trained data.

By the way, in Turkish saying 'lan bi siktir git' makes you quite rude.

## How It Works

Genderizer is a module which tries to detect gender by looking given first names and/or analyzing sample text of a
person.

If a first name is definitely used for only one gender, the system will accept this gender and will not make any further
analysis. For example, while 'Mustafa', 'Osman', 'Hasan' is used in Turkish only for male; 'Fatma', 'Ceyda', 'Elif' only
for female.

When looking at first names does not infer any gender for sure, the system will make text analysis if it is given. For
example; 'Ekim', 'Meric', or 'TÃ¼may' is used for both male and female.

The text analysis is the classification of sample texts. It simply try to compute the probability of being male or
female mining the sample text. In this system Naive Bayesian Classification is adopted and [naiveBayesClassifier][1] is
used.

TODO: give a few examples

## Customization and Optimization

### Using Memcached For Speed

```python
"""
Under heavy usage, for example tens of thousands detection request
in a few seconds the default configuration could not meet the
demand. By the default configurations, genderize will load necessary
data from files and this is well known to be slow. Instead of each
time loading data into memory, doing this one time will be clever
approach. One of the best way of this approach is to use memcached.
For more information have a look at the documentation of memcached.

Genderizer provides a memcached interface to store first names in 
memory. To active this interface, you need to instantiate 
memcachedNamesCollection interface and pass it to genderizer3 while 
initializing it.
"""

from genderizer3.memcachedNamesCollection import MemcachedNamesCollection

# For memcached, do not forget to setup the memcached server.
MemcachedNamesCollection.memcacheHost = '127.0.0.1:11211'
Genderizer.init(
    namesCollection=MemcachedNamesCollection
)
print
Genderizer.detect(firstName='John')
```

### Using Mongodb

```python
"""
If you want to use Genderize on Mongodb for arbitrary reasons, the
MongoNamesCollection first names collection interface will do much
of the necessary works for you.
"""
from genderizer3.mongoNamesCollection import MongoNamesCollection

MongoNamesCollection.mongodbURL = 'mongodb://192.168.1.170'
Genderizer.init(
    namesCollection=MongoNamesCollection
)
print
Genderizer.detect(firstName='Marry')

```

### Custom Text Classifier

```python
"""
NaiveBayesClassifier is adopted as the default classifier. But you
can use another, entirely different classifier; as long as the
classifier has a 'classify' method taking text as a parameter.

For more information please have a look at the naiveBayesClassifier
project's documentation.
https://github.com/muatik/naive-bayes-classifier
"""

from naiveBayesClassifier import tokenizer
from naiveBayesClassifier.classifier import Classifier
from cachedModel import CachedModel

Genderizer.init(
    lang='en',
    classifier=Classifier(CachedModel.get('en'), tokenizer)
)

print
Genderizer.detect(firstName='fikret', text='annemle kahve keyfi')
```
