Description : Back on the principles of intelligent processing applied by search engines not only to find pages likely to meet the needs of the user but also to extract the answers from these pages and summarize them on the result page. Google search engine does so through its "Rich Snippet" which is powered by metadata submitted by the producers of information via the "Structured Data Test Tool" made available by the giant of Mountain View . It was still necessary to agree on a shared vocabulary for metadata: "Titre" in French = "Title" in English or even "Akọle" in Yoruba (according to an online translator). Google, Microsoft, Yahoo! and Yandex therefore agreed to create in 2011 schema.org, a real metadata classification for web pages and electronic messages. Then, the limitations of these techniques are mentioned, the most notable being paradoxically the lack of precision of these metadata due to an overly universal scheme.
