L&amp;rsquo;indexation des connaissances peut-elle s&amp;rsquo;exercer au profit de l&amp;rsquo;interdisciplinarit&amp;eacute;&amp;nbsp;? Nous tentons d&amp;rsquo;y r&amp;eacute;pondre dans cet article. Nous proposons une exp&amp;eacute;rimentation visant &amp;agrave; utiliser la classification internationale des brevets (CIB) comme pivot de classement interdisciplinaire. Le terrain &amp;eacute;tudi&amp;eacute; concerne la &amp;laquo;&amp;nbsp;science en train de se faire&amp;nbsp;&amp;raquo;, ici les th&amp;egrave;ses de doctorat, mais peut &amp;ecirc;tre calqu&amp;eacute; &amp;agrave; d&amp;rsquo;autres sources de donn&amp;eacute;es. Nous d&amp;eacute;taillons les r&amp;eacute;sultats par un exemple li&amp;eacute; directement aux sciences dures, mais qui peut &amp;ecirc;tre &amp;eacute;galement appliqu&amp;eacute; aux sciences humaines et sociales. Cette &amp;eacute;tude originale est au croisement du monde acad&amp;eacute;mique et du monde technologique.&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/p&gt;

Can the indexation of knowledge be applied in favor of interdisciplinarity? We try to answer it in this article. We propose an experiment to use the International Patent Classification (IPC) as an interdisciplinary pivot. The field studied concerns &amp;quot;science in the making&amp;quot;, here doctoral theses, but can be modeled on other sources of data. We detail the results by an example directly related to the hard sciences, but which can also be applied to the human and social sciences. This original study is at the crossroads of the academic world and the technological world.&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/p&gt;
