We have a dataset for Baybayin characters — let’s say character A and then character BA. SVM uses techniques or mathematical methods that can separate the two datasets to determine characters BA and A,” Pino said in a release.</p><p>The group collected over 1,000 images for each Baybayin character, gathering a total of 110 paragraphs from different websites that have either hand- or type-written Baybayin, Latin, or Baybayin and Latin writing, “Adding more character images improves the recognition rate of SVM,” Pino explained.</p><p>The current OCR system can spell out the Latin equivalent of the Baybayin characters on a page, thus producing a transliterated version of the text but the researchers are looking to enable it to do so much more, they said.</p><p>They also plan to make the OCR system more aware of the context of Baybayin words and phrases to be a full-fledged translator and make the system work both ways, with the ability to convert Latin words with foreign sounds into Baybayin.</p><p>“We’re trying to refine the software we developed to make it easier for future users to navigate it. We also dream of creating a mobile application that automatically and accurately translates Baybayin characters just by hovering over the phone,” Mendoza said.</p><p>Mendoza said that it was challenging to get the OCR system to translate Baybayin words and sentences accurately. </p><p>“For now the system can’t distinguish between some Baybayin characters that are similar in writing, such as E and I, and O and U. We also have a lot of words that have different Latin equivalents. The algorithm we used shows all possible translations of the Baybayin words,” he said.</p><p>The team published their data to encourage more researchers to conduct studies on Baybayin and OCR. </p><p>“We cleaned the data in such a way that researchers could use it in analyzing Baybayin through other algorithms. We made the data readily available for use, so researchers wouldn’t go through the difficulty we experienced in gathering data,” Mendoza said.</p><p>The scientists said that Baybayin is living proof that Filipinos have our own technically-sophisticated traditions, noting that conducting more research on the said text will help preserve this heritage. </p><p>“This can be forgotten. It’s important to have a record of each Baybayin character — even having digitized ones,” Sambayan said.</p><p>“We’re hoping that through this OCR system, we could preserve and pass on the knowledge of understanding Baybayin to future Filipino generations,” she added.</p><div><strong>FROM THE ARCHIVES:</strong></div><figure class="op-interactive"><iframe allow="autoplay; fullscreen" frameBorder="0" height="100%" id="ivsplayer01" scrolling="no" src="https://player.ivideosmart.com/ivsplayer/v4/dist/html/iframe-src.html?iframeid=ivsplayer01&amp;key=e8c22c015ca9eafa76f1e3edfa03c603&amp;spid=3001339&amp;vid=2715063" width="100%"></iframe></figure><div class="iwantbar">Watch more News on <a href="https://www.iwanttfc.com/#!/browse/Genres/News/tag_id_genres/id_news" target="_blank">iWantTFC</a></div>

Filipino mathematicians from the University of the Philippines Diliman have invented a computerized method to convert text written in the ancient Filipino Baybayin writing system into understandable text.
