Luca Scagliarini pointed out that the present information discovery suffered from both information overload and information underload due to a lack of meaning-based text processing. He reviewed current technologies and illustrated problems with shallow automatic linguistic analysis and the lack of 'understanding' of the meaning that is encoded in the relationships between verbs, prepositions and nouns. He illustrated how a 'deep semantic analysis' based on the analysis of relationships works in Expert System's new semantic intelligence software, Cogito. Cogito utilizes an innovative 'semantic network' to achieve improved machine 'understanding'. The semantic network contains 350,000 definitions and 2.8 million relationships for the English language vocabulary.
