Hebrew and Arabic are known for their complex morphology (linguistic forms and inflections system), especially in the unvowelized spelling. Melingo’s morphological analysis enables to analyze each word and each unvowelized inflected form in a text and to decode it according to its context and based on a vast/rich linguistic database. (For example, the word ‘מספר’ can be read in several ways according to the sentence in which it is embedded: מִסְפָּר, מְסַפֵּר, מִסֵּפֶר, מִסַּפָּר and so forth. The morphological analysis recognizes each form according to its context and thus enhances significantly the ability to summarize the text.
Natural Language Processing (NLP) is one of the most rapidly developing areas of software technology today. Melingo’s groundbreaking technology is unique within this field, in that it succeeds in breaking down text into workable components, using efficient algorithms, economical in data capacity.
