Tamilpesu.us update – Text Summarizer

Tamilpesu.us updated on Aug 8th. This brings all bug fixes of the development in Open-Tamil from March 2018 to present, and new functionality via Tamil text summarizer. This works on text analysis of essay input to split into sentences and words, and forms a correlation matrix to develop a score based off that we pull sentences from text into final summary. Give it a try http://tamilpesu.us/


Text summarizer output of the article from The Hindu Tamil newspaper. Its quite relevant summary in this case, providing an agreeable output.

Unfortunately we are not able to put the Tamil word classifier [using SciKit Learn and Python] online since currently the Python/Django dependency on AWS machine is incompatible; wait for that in future or try it out by yourself.

Thanks to all our contributors, as always to keep this volunteer work going.


Tamilisch – தமிழ் மொழியின் பெயர்

முதல் முரை நான் செருமன் மொழி கற்கும் போது தமிழ் மொழியின் பெயர் Tamilisch என்று சொன்னாங்க. ஜெர்மென் கற்க வாய்ப்பை பயன்படுத்திக்கொள்ளமுடியவில்லை.

ஒரு தானியங்கி ஆட்டொமாடிக்கா பல மொழிகளில் தமிழ் மொழியின் பெயர் இதோ!

Apple’s second Keyboard for Tamil

Traditionally Apple Keyboard for Tamil has supported “Tamil Standard” [there are some anecdotal frustrations of senior Tamil computing innovators about Apple culturally appropriating this ‘Tamil99’ as their ‘standard’ and stripping away any mention of Tamil99, but this is for another day. Shh.] or Tamil99 layout which is quite useful for most practitioners. However one may observe in Tamil computer user community the prevalence of preference for transliteration input [Google has trained us by providing some good tools here, and Apple follows suit].

Beginning with iOS 12, Apple has released a Tamil transliterator. இதன் வழி எப்படியும் தமிழில் டைப்பிங் செய்யலாம்.

Apple iOS v12 update provides an additional IM by Tamil Keyboard with transliteration input. This July, 2018 updates provides this facility in Apple iPhone and Mac devices via iOS 12.

This method is useful for typing short sentences for my use so far, but I have to spend long enough time to pick it up. I hope Apple continues to support this feature and introduce Tamil input to several newer younger generation folks.

Plusses include – easy predictive input. Minusses include – somewhat non-intuitive mapping for certain letters. I cannot post a full review here, only for lack of trying. Thanks, Apple.

Language Transformations

Question  of Translation

How can you convert a text like “Me Amor!” to “என் உயிரே!” [from Spanish to தமிழ்] ? Lets  assume we have Spanish to English and Tamil to English translators [bidirectional with English] then we can convert Spanish to English then to Tamil. Likewise one can translate between any two languages from a clique of languages [so far as the clique is defined such that each language can be translated to at least one other language in clique].

Development – Theory

Language can exist as text (print/message/document) or speech (audio, conversations) etc. Ideas are represented in any language. Ideas originate from one language and move to another, or sometimes originate iñ many lañguages simultaneously. Ideas cañ cross from oñe language to añother via text or speech.

In mathematical terms if we write L as set of lañguages = { L1, L2, .. Ln} and then if we define each language as a tuple Li = (Ti,Si) then we may further define mathematical function operating on text and converting it to speech as :

TTSi : Ti -> Si

we may define a function speech recognition as,

ASRi : Si -> Ti

we may also define a translation function as,

TXij : Li -> Lj

Essentially what we can do is by representing the language as a node in a graph with two text and speech parts to it, we may connect these nodes to each other via the edges – functions – like ASR and TTS, and to nodes of other languages via translators function edge.

In a graph with only two languages [English, Tamil] with all edges representing functions like TTS, ASR within same language and functions like Translator between two languages (one for each direction) we see a graph like the following:

Fig. 1: Language transformation graph. Nodes represent languages and their components. Edges represent functions like TTS, ASR [for same language] and Translators [directional between languages]. Clearly we may see this is a directed graph with ability to go from a specific language to another language in text or speech or both forms, provided a path exists from source to target language. Using such a graph with no orphan nodes, we may have universal translation powers from language A to language B [so far as bidirectional connectivity is present with at least one neighbor].

Problems to Ponder

So the curious reader now having a background of representing the translation problem as a graph problem of reaching node B from node A, can use rich set of path finding algorithms and shortest distance algorithms may attempt to answer some of these questions:

  1. What is the graph criteria for a language to have no translations ?
  2. What is the graph criteria for a language to not be able to have virtual assistant ? [Siri, Cortana, Alexa etc.]
  3. Conversely, to 2, what is minimum criteria [necessary but not sufficient] to have a virtual assistant [that can speak and listen] ?
  4. Given two paths to translating from language A -> F, which are of two different lengths which one would you choose and why? Assume all jumps have a uniform information loss. What if information loss at each edge is non-uniform, how can you optimized such a problem ?
  5. How would you introduce a new language into this graph so that it maybe translated to all other languages [unidirectionally] ?
  6. How would you introduce a new language into this graph so that it can be bi-directionally translated ?
  7. How can you represent the transliteration function in this graph ?

Answers will be posted soon! Feel free to leave your comments in section below.


Dispatches from Kovai, India

Kovai – Coimbatore, India – also known as Manchester of India, and various monickers for its beautiful weather, Tamil dialect, and cool weather at foothills of the Nilgiris-Ooty mountain range and clear waters from Sravani river, it is a microcosm of all that is nice and beautiful in முல்லை Tamilnadu.

Our team of fearless open-source enthusiasts añd contributing developers of open-tamil project, Shrinivasan and our newest contributor this year Syed Abuthahir made an impressive presentation at the conference, and gained new clients for the open-tamil library demonstrating the prowess of various tools, particularly from the web-interface http://tamilpesu.us

Growth and evolution of Open-Tamil – presented at TNAU, Coimbatore. Full slides here

Syed has gladly shared the presentation with me, and I put it up on slideshare for all of us to read/comment. Thanks to all earnest contributions of time, effort, code and thought towards this project over the years!

Best Regards,
