== A spell checker for Indic language that understands inflections =='''Project''': 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 occurring in Indian languages especially south Indian languages. The dictionary we have for Malayalam spellchecker have about 150000 words. Of course we can expand the dictionary, but that doesn't have 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 with hunspell. If that is not feasible(hunspell upstream is not active), develop an algorithm and implement it. Recently Tamil attempted developing a spellchecker using Hunspell with multi level suffix stripping. You can see the result here https://github.com/thamizha/solthiruthi. Our attempt should be first to use Hunspell to achieve spellchecking with agglutination and inflection. Probably it will require lot of scripting to generate suffix patterns, we can ask help from existing language communities too. If Hunspell has limitation with multi level suffxes- sometimes Indian languages require more than 5 levels of suffix stripping, we need to document it(bug and documentation) and try to attempt python based solution on top of SILPA framework. * '''[https://savannah.nongnu.org/task/index.php?12558 Savannah Task]'''* '''Expertise required''': Average level understanding of grammar system of at least one Indian language* Complexity: Advanced* '''Mentor''' : Santhosh Thottingal ==Indic rendering support in ConTeXt==Add proper '''Project''': ConTeXt is another TeX macro system similar to LaTeX but much more suitable for design.

MapServer is To develop an open source development environment automatic speech recognition system in a language, acoustic model and language model has to framed for building spatially enabled internet applicationsthat particular language. Acoustic models characterize how sound changes over time. It captures the characteristics of basic recognition units. OpenLayers The language model describes the likelihood, probability, or penalty taken when a sequence or collection of words is an open source JavaScript library for displaying map data seen. It attempts to convey behavior of the language and tries to predict the occurrence of specific word sequences possible in the language. Once these two models are developed, it will be useful to every one doing research in web browsersspeech processing. For Indian languages Hindi, Tamil, Telugu and Marati, ASR systems have been developed using sphinx engine. OpenLayers In this project work is used by OpenStreetMap aimed at developing acoustic model and language model for Malayalam. '''Mentor''': Deepa P.
