Lecture 2: From Semantics to Semantic-Oriented Applications

From the “Natural Language Processing” LinkedIn group: John Kontos, Professor of Artificial Intelligence I wonder whether translating into formal logic is nothing more than transliteration which simply isolates the part of the text that can be reasoned upon using the simple inference mechanism of formal logic. The real problem I think lies with the part of text that CANNOT be translated one the one hand and the one that changes its meaning due to civilization advances. My own proposal is to leave NL text alone and try building inference mechanisms for the UNTRANSLATED text depending on the task requirements. All the best John” … Read entire article »
