Task ideas for Google Code-in

This is the task ideas page for Google Code-in, here you can find ideas on interesting tasks that will improve your knowledge of Apertium and help you get into the world of open-source development.

The people column lists people who you should get in contact with to request further information. All tasks are 2 hours maximum estimated amount of time that would be spent on the task by an experienced developer, however:

1. this does not include time taken to install / set up apertium.
2. this is the time expected to take by an experienced developer, you may find that you spend more time on the task because of the learning curve.

Categories:

• code: Tasks related to writing or refactoring code
• documentation: Tasks related to creating/editing documents and helping others learn more
• research: Tasks related to community management, outreach/marketting, or studying problems and recommending solutions
• quality: Tasks related to testing and ensuring code is of high quality.
• interface: Tasks related to user experience research or user interface design and interaction

You can find descriptions of some of the mentors here: List_of_Apertium_mentors.

code	Fix a memory leak in matxin-transfer	The matxin-transfer program is a component of the Matxin MT system, a sister system to Apertium. Run valgrind on the code and find and fix a memory leak. There may be serveral.	c++	Fran
code	Refactor/mege the main "processing" functions of lrx-proc	lrx-proc has two modes, "-m" mode and default mode. They are implemented by each their huge function, nearly identical to each other. Refactor the code to remove the redundancy, and run tests on lots of text with several language pairs to ensure no regressions.	c++	Fran, Unhammer
code	Profile and improve speed of lrx-proc	lrx-proc is slower than it should be. There is probably some low-hanging fruit. Try profiling it and implementing an improvement.	c++	Fran, Unhammer
research	See if you can precompile xpath expressions or xslt stylesheets	An XSLT stylesheet is a program for transforming XML trees. An Xpath expression is a way of specifying a node set in an XML tree. Investigate the possibility of pre-compiling either stylesheets or xpath expressions.	parsing	Fran
research	Review literature on linearisation of dependency trees	A dependency tree is an intermediate representation of a sentence with no implicit word order. Linearisation is finding the appropriate word order for a dependency tree. Do a survey of the available literature and write up a review.	parsing	Fran, Schindler

code	Convert Chukchi Nouns to HFST/lexc	There is a freely available lexicon of Chukchi, a language spoken in the north-east of Russia. The objective of this task is to convert part of the lexicon covering nouns to lexc format, which is a formalism for specifying concatenative morphology.		Fran
code	Convert Chukchi Numerals to HFST/lexc	There is a freely available lexicon of Chukchi, a language spoken in the north-east of Russia. The objective of this task is to convert part of the lexicon covering nouns to lexc format, which is a formalism for specifying concatenative morphology.		Fran
code	Convert Chukchi Adjectives to HFST/lexc	There is a freely available lexicon of Chukchi, a language spoken in the north-east of Russia. The objective of this task is to convert part of the lexicon covering nouns to lexc format, which is a formalism for specifying concatenative morphology.		Fran
interface	Make a design for a web-based viewer for parallel treebanks	(also for viewing diff annotation for same sentence)	HTML,CSS	Fran, Schindler

interface	Design an annotation tool for adding dependencies	Like c.f. brat
code	Train lexical selection rules	from a large parallel corpus for a language pair		Fran
documentation	Document how to set up the experiments for weighted transfer rules			Fran
code	convert UD treebank to apertium tags, use unigram tagger	(see #apertium logs 2016-06-22)
code	Write a script to extract sentences from CoNLL-U	where they have the same tokenisation as Apertium.		Fran

code	Implement `lt-print --strings` lt-print -s		c++	Fran, wei2912
code	Implement lt-expand -n	Implement an algorithm that prints out a transducer but only follows n cycles.	c++	Fran, wei2912
code	in-browser globe with apertium languages as points	Use d3 globe to make an apertium language/pair viewer (like pairviewer), maybe based on this or this or this. This file contains coordinates of Apertium languages.	js,html,maps	Firespeaker, kvld
code	Write a program to detect contexts where a path in a compiled transducer begins with a whitespace		c++
code	Make the lt-comp compiler print a warning when a path begins with a whitespace.	Common mistake in dix files is to have some bad whitespace at places, this needs to be aqutomatically detected in the compilation tool and warning to user issued.	c++
	apertium-mar-hin: make the TL morph for any part of speech less daft	Some morph in Marathi or Hindi are currently daft.	morphology	vin-ivar
	add indic scripts/formal latin transliterations	Translitteration is a ways to write stuffs in different scripts. Currently some indic scrpts are done only to some WX transliterator	python	vin-ivar
code	apertium-hin: more consistency with apertium-mar for verbs	Verbs in Marath and Hindi are incosistently.	morphology	vin-ivar
code	apertium-mar: replace cases with postpositions	Marathi cases are postpositions	morphology	vin-ivar
