It&#8217;s up on HuggingFace now:<\/p>\n<p><a href=\"https:\/\/huggingface.co\/datasets\/tomron87\/hebrew-wikipedia-sentences-corpus\">https:\/\/huggingface.co\/datasets\/tomron87\/hebrew-wikipedia-sentences-corpus<\/a><\/p>\n<p><strong>Why this exists:<\/strong> Hebrew is seriously underrepresented in open NLP resources. If you&#8217;ve ever tried to find a clean, large-scale Hebrew sentence corpus for downstream tasks, you know the options are&#8230; limited. I wanted something usable for language modeling, sentence similarity, NER, text classification, and benchmarking embedding models, so I built it.<\/p>\n<p><strong>What&#8217;s in it:<\/strong><\/p>\n<ul>\n<li>~11 million sentences from ~366,000 Hebrew Wikipedia articles<\/li>\n<li>Crawled via the MediaWiki API (full article text, not dumps)<\/li>\n<li>Cleaned and deduplicated (exact + near-duplicate removal)<\/li>\n<li>Licensed under CC BY-SA 3.0 (same as Wikipedia)<\/li>\n<\/ul>\n<p><strong>Pipeline overview:<\/strong> Articles were fetched through the MediaWiki API, then run through a rule-based sentence splitter that handles Hebrew-specific abbreviations and edge cases. Deduplication was done at both the exact level (SHA-256 hashing) and near-duplicate level (MinHash).<\/p>\n<p>I think this could be useful for anyone working on Hebrew NLP or multilingual models where Hebrew is one of the target languages. It&#8217;s also a decent foundation for building evaluation benchmarks.<\/p>\n<p>I&#8217;d love feedback. If you see issues with the data quality, have ideas for additional metadata (POS tags, named entities, topic labels), or think of other use cases, I&#8217;m all ears. This is v1 and I want to make it better.<\/p>\n<\/div>\n<p><!-- SC_ON -->   submitted by   <a href=\"https:\/\/www.reddit.com\/user\/tomron87\"> \/u\/tomron87 <\/a> <br \/> <span><a href=\"https:\/\/www.reddit.com\/r\/datasets\/comments\/1r4jrax\/i_built_an_open_hebrew_wikipedia_sentences_corpus\/\">[link]<\/a><\/span>   <span><a href=\"https:\/\/www.reddit.com\/r\/datasets\/comments\/1r4jrax\/i_built_an_open_hebrew_wikipedia_sentences_corpus\/\">[comments]<\/a><\/span><\/p><div class='watch-action'><div class='watch-position align-right'><div class='action-like'><a class='lbg-style1 like-39030 jlk' href='javascript:void(0)' data-task='like' data-post_id='39030' data-nonce='848a019030' rel='nofollow'><img class='wti-pixel' src='https:\/\/www.graviton.at\/letterswaplibrary\/wp-content\/plugins\/wti-like-post\/images\/pixel.gif' title='Like' \/><span class='lc-39030 lc'>0<\/span><\/a><\/div><\/div> <div class='status-39030 status align-right'><\/div><\/div><div class='wti-clear'><\/div>","protected":false},"excerpt":{"rendered":"<p>Hey all, I just released a dataset I&#8217;ve been working on: a sentence-level corpus extracted from the&#8230;<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[85],"tags":[],"class_list":["post-39030","post","type-post","status-publish","format-standard","hentry","category-datatards","wpcat-85-id"],"_links":{"self":[{"href":"https:\/\/www.graviton.at\/letterswaplibrary\/wp-json\/wp\/v2\/posts\/39030","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.graviton.at\/letterswaplibrary\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.graviton.at\/letterswaplibrary\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.graviton.at\/letterswaplibrary\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.graviton.at\/letterswaplibrary\/wp-json\/wp\/v2\/comments?post=39030"}],"version-history":[{"count":0,"href":"https:\/\/www.graviton.at\/letterswaplibrary\/wp-json\/wp\/v2\/posts\/39030\/revisions"}],"wp:attachment":[{"href":"https:\/\/www.graviton.at\/letterswaplibrary\/wp-json\/wp\/v2\/media?parent=39030"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.graviton.at\/letterswaplibrary\/wp-json\/wp\/v2\/categories?post=39030"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.graviton.at\/letterswaplibrary\/wp-json\/wp\/v2\/tags?post=39030"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
