A clear and concise description of what the problem is.</strong></p><p>The<a href=\"http://futureu.europa.eu/\" target=\"_blank\"> futureu.europa.eu</a> platform is one of the first Decidim instances to be using the machine translation feature.</p><p>Based on the proposal “Machine translation enhancement for source language detection edge cases” we’d like to offer a more complete solution to the source language problem.</p><p><strong><br></strong>As described in the additional context, adding a dropdown for language selection on UGC (User generated content) forms might not be enough as some users won’t notice it or take the time to select the right language.</p><p><br></p><p><strong>Describe the solution you'd like</strong></p><p>We propose to leverage on the automatic language detection feature that some machine translation services offer. This way we’d be able to select the source language for the user.&nbsp;</p><p>The issue with automatic language detection is that it doesn’t work well on short sentences like (OK , Da etc.). Also some languages are very close (ex : Romanian and Moldavian)&nbsp; and errors can be made.</p><p>Considering the user experience needs to be as smooth as possible, and in order to avoid issues with availability of the language detection software, the implementation we are considering is to have a Javascript widget that would query the external service through AJAX. This will allow us to use external services like google translate, or add our own implementation (for instance a small Python script that would allow language detection - Please note there are no mature enough libraries to use in the ruby context). Also, this implementation would allow the user to select the language from a drop down in case the Confidence score provided by the used library is not high enough.&nbsp;</p><p><strong>Acceptance criteria</strong></p><p>Given that I’m logged in<strong><br></strong>When I am writing a comment / proposal / meeting in the same language as the one I selected to browse the website<strong><br></strong>Then the form displays the language selection dropdow with my preferred language.</p><p>Given that I’m logged in<strong><br></strong>When I am writing a comment / proposal / meeting in another language than the one I selected to browse the website<strong><br></strong>If the language detection is at a high confidence level<strong><br></strong>Then the language of my contribution is automatically selected and a message offers me via a click to display the language selection dropdown to correct if any mistake was made.</p><p>If the language detection is at a low confidence level<strong><br></strong>Then a message appears explaining the situation and showing the detected language and its confidence level (%).&nbsp;</p><p><strong><img src=\"https://lh4.googleusercontent.com/1uNjNWKuQ0hzm9VZ6rfCz5SAc-_Syp0Nrvkr2g3Oll2-BxbbpwNfHAZIf_YaSUjcoqUoKgIf6fTzm_VCNodlSJgsknCUGhc8I9a1j4zhL795bdbBOGBF05C0Gf92oHcxryW4c6tQ\"></strong></p><p><strong><br></strong>Given I am a logged in user<strong><br></strong>When I create an event of proposal<strong><br></strong>Then the language detection should be done only by one field, the body of the content added.</p><p><strong>Describe alternatives you've considered</strong></p><p>None</p><p><strong><br>Additional context</strong></p><p>This builds upon the meta proposal “Machine translation enhancement for source language detection edge cases”</p><p><strong><br></strong>Resources : Libraries for automatic language selection&nbsp;</p><p><a href=\"https://github.com/ankane/fastText\" target=\"_blank\">https://github.com/ankane/fastText</a> &lt; Ruby fast text implementation&nbsp;</p><p><a href=\"https://github.com/bung87/whatlangid\" target=\"_blank\">https://github.com/bung87/whatlangid</a> &lt; Python library&nbsp;</p><p><a href=\"https://github.com/tremend-cofe/language-detection\" target=\"_blank\">https://github.com/tremend-cofe/language-detection</a> &lt; Python implementation of the language detection application (based on whatlangId)</p><p><strong><br>Does this issue could impact on users private data?</strong></p><p>No</p><p><strong>Funded by</strong></p><p>EU Commission</p>"},"title":{"en":"Use automatic language detection for the machine translation feature"}}

This fingerprint is calculated using a SHA256 hashing algorithm. In order to replicate it yourself, you can use an MD5 calculator online and copy-paste the source data. ×
