Save data in Mongodb about natural HOT 10 CLOSED

Yeah it's Bayesian classifier module

from natural.

Support for a number of storage methods has been added. See #727

how did you load the model can u provide some code snippets

from natural.

Of course, we can build everything we want :-)

I am curious to know which module you are working with? Is it the Bayesian classifier?

I think this would be a configuration to choose between database and JSON. In the end a back-end to save to and load from different types of storage methods. But starting with a choice between JSON and database would be great.

Some design ideas:

• Pass a config object to Classifier in classifier.js. Also put the stemmer in there to prevent many arguments when creating the object.
• Adapt the load and and save methods to work with mongodb depending on the configuration: return a key on save, and load using a key. Instead of filenames.

can anyone provide code snippets of Bayesian classifier module that's compatible with the latest package version

from natural.

You could take a look at the tests:

This will be amazing! The classifier could receive an object that implements an interface, allowing us to access the data and handle it effectively. This enables the user implementing 'natural' to choose their preferred database. Instead of loading all the data at once, we could simply read from the database.

Yes, you could store a trained classifier in a database. Later on you could retrieve and re-instate it as an object using `SetPrototypeOf``.

Wrt design I am considering a backend that supports file-based storage and MongoDB to begin with by means of plugins or something like that. In this way we can abstract away the concrete storage method.
