Named Entity Recognition

Embeddings

Morphological Analysis

Stemmer

  • PersianStemmer – (JavaDelphi,C# and Python) – PersianStemmer is a longest-match stemming algorithm that is based on pattern matching. It uses a knowledge base which consist of a collection of rules named “patterns”. Furthermore, the exceptions and problems in the Persian morphology have been studied, and a solution is presented for each of them. So our stemmer evaluated. Its result was much better than the previous stemmers.

Sentiment Analysis

  • polyglot (polarity) – Natural language pipeline that supports massive multilingual applications (like lokenization (165 languages), language detection (196 languages), named entity recognition (40 languages), part of speech tagging (16 languages), sentiment analysis (136 languages), word embeddings (137 languages), morphological analysis (135 languages), transliteration (69 Languages)).
  • NRC-Persian-Lexicon – NRC Word-Emotion Association Lexicon useful for persian sentiment analysis.

Spell Checking

  • async_faspell -Persian spellchecker. An algorithm that suggests words for misspelled words.

Information Extraction

Data

Part-of-Speech Tagger

  • Bijankhan Corpus – Bijankhan corpus is a tagged corpus that is suitable for natural language processing research on the Persian (Farsi) language. This collection is gathered form daily news and common texts. In this collection all documents are categorized into different subjects such as political, cultural and so on. Totally, there are 4300 different subjects. The Bijankhan collection contains about 2.6 millions manually tagged words with a tag set that contains 40 Persian POS tags.
  • Mojgan Seraji Corpus – Uppsala Persian Corpus (UPC) is a large, freely available Persian corpus. The corpus is a modified version of the Bijankhan corpus with additional sentence segmentation and consistent tokenization containing 2,704,028 tokens and annotated with 31 part-of-speech tags. The part-of-speech tags are listed with explanations in this table.
