The problem to solve

2

• Nowadays information published on internet is not manageable any

more; the consequence is that any internet search is not precise.

• Due to the overwhelming amount of information and the inherent nature
• f internet (polling protocol), manual internet retrieval can be a human

exhaustive activity;

• The relevant information is only a fraction of the available one;
• All these problems, that lead to a loss of information (hence power),

pertain to the information created by a company as well;

• Data Monitoring:
• Finance, stock markets…
• Information monitoring and analysis (document repositories, news, web

press, news feeds, blogs, mails,…)

• Brand analysis (brand monitoring, sentiment analysis,…)
• Massive text indexing and retrieval
• …by and large any domain where the retrieval and analysis of information

creates new (and more useful) information;
