Semantic Type - Word Sense Disambiguation

STI (Semantic Type Indexing) uses JDI methodology as the basis to calculate the average ST scores from the Word-St table. STI can be used for word sense disambiguation by selecting the best semantic type. STWSD is a tool developed for this purpose.

• The selected Semantic Type in the abbreviation form

III. Algorithm

• Find variants of ambiguous word
  • Use Lexical Tools fruitful variants flow
  • Remove fruitful variants have punctuation (no punctuation for words in STI)
  • Unify and sort fruitful variants
• Check WSD inputs
  • Check if input text is empty
  • Check if ST Candidates are legal STs
• Find forced legal words
  • Tokenize all variants into words
  • Unify and sort
• Find the ST with highest score
  • Use default input filter (or tokenize word)
  • Get STI scores (DC & WC)
  • Use combined score system
  • Find the ST with highest score
