Internationalize SILPA project with Wikimedia jquery projects


SILPA project has many Indic language applications, but as of now, if somebody want to input in Indian languages, there is no built in tool in it. Similarly, the application is not internationalized. Both of these can be achieved by using the jquery.ime and jquery.i18n libraries from Wikimedia. A sample implementation is avaliable in our website. The i18n should be in the SILPA flask framework with a nice templating system. Similarly the interface should have webfonts using jquery.webfonts library.

Expertise required: jquery, css, html5, python

A spell checker for Indic language that understands inflections


SILPA project has a spellchecker written using python with a not so simple algorithm. But still it is not capable of handling inflection and agglutination happening in Indian languages especially south indian languages. The dictionary we have for Malayalam spellchecker is having 150000 words. Of course we can expand the dictionary, but that has no much value since words can be formed in Malayalam or Tamil etc by joining multiple words. In addition to that, words get inflected based on grammar forms(sandhi), plural, gender etc. Hunspell has a system to handle this, but so far nobody succeeded in getting it working for multi level suffix stripping as required for Malayalam. Some times a malayalam word can be formed by more than 5 words joining together. We will need a word splitting logic or a table taking care of all patterns. The project is to attempt solving this inside hunspell. If that is not feasible(hunspell upstream is not active), develop and algorithm and implement it.

Expertise required: Basic understanding of grammar system of atleast one Indian language

Indic rendering support in ConTeXt.

ConTeXt is another TeX macro system similar to LaTeX but much more suitable for design. (We already have rendering module in SILPA this can be improved to allow the implementation of above idea. )

Create Bold and Italic variants for Meera and Rachana

Project :The Meera font has only regular version now. Synthetic bold and italic is not perfect and suitable for Malayalam. Create a bold and italic variant version for the Meera and Rachana fonts

Expertise required: Digital typography, good understanding of Malayalam writing system, fontforge, understanding of rendering engines like Harfbuzz.

Port remaining modules to the new flask based Silpa


Expertise required:

Mentor : Rajeeesh Nambiar/ Jishnu

Provide REST API for new flask based Silpa, including conversion of templates to this REST API from JSON RPC.


Expertise required:

Mentor : Vasudev/Jishnu

Separate templates from SILPA and have it inside modules packaged for pypi


this should give more idea on it

Converting indic processing modules currently in SILPA into Jquery library

Project: Port some of the silpa alogorithms to javascript

Expertise required: javascript, python

Mentor :Vasudev/Jishnu

Improving cross language transliteration system.


Currently only Kannada and Malayalam are perfect rest all are first converted to Malayalam then to English due to lack of language internal. Also currently for English to Indic we use CMUDict so transliteration capability is limited to words in CMUDict only probably we could develop better method for English to Indic transliteration

Improving the webfonts module in Silpa using jquery.webfonts and proving more Indic and complex fonts as part of it.

Adding Indic Sript Rendering Support to GIS applications

Add proper Indic / Malayalam rendering to Mapnik

Mapnik is a free mapping toolkit, written in C++. One of it's major users is OpenStreetMap. If you check OpenStreetMap, you can see that Languages like Russian, Arabic, Persian, Chinese etc are rendered in it (Not sure whether they are properly rendered or not). The lack of proper Indic support is the major reason for the absence of Malayalam.

Add Indic / Malayalam rendering to MapServer + OpenLayers stack.

Both are OSGeo projects, and used in most of the WebGIS applications recently. MapServer is an open source development environment for building spatially enabled internet applications. OpenLayers is an open source JavaScript library for displaying map data in web browsers. OpenLayers is used by OpenStreetMap for its "slippy map" map interface.

Add proper Indic / Malayalam support and rendering to GRASS GIS.

It is used by a number of organizations for analysing GIS data, creating maps etc. GRASS also is an OSGeo project. It is in the process of rewriting the old Tcl/Tk interface in the new wx-python.

Building a systme and API's for accessing and upadating Malayalamgrandham Bibligiography Data

[1] Malayala Grantha Vivaram is a project intended to make available reliable bibliographic information on all Malayalam books published in Kerala and elsewhere. This Open data set contains Complete bibliography data from first Impression to 1995. This project wants to add following features to Malayalagrandham DB and build it as a bibliography web service 1. Facility for adding copyright expired books to malaylagrandha vivaram 2. Adding ISBN 3. Building Interface for Publishers through with they can contribute their publication bibliography . 4. Similar module for Libraries . That will be added to found in library section of each book 5. A module for building qr code of bibliography with a malayalagrandham link . It can be used by publishers and libraries 6. Crowd sourced way for input and an evaluation interface for submissions. 7. MARC21 and MARCXML support
