The Web is large and information is present in many forms. Complex techniques are necessary to discover the hidden structure of content and a single software provider cannot be expert on all them. Thus the integration platform comes as a perfect solution enabling the use of the best tools for each function. In this presentation we will present OSINT challenges and its growing importance. Then we will detail the WebLab approach to build flexible and scalable OSINT applications matching the fast-paced nature of OSINT. From semantic data models to upper architecture passing through selected technologies used, the presentation will do the complete tour of the WebLab project.
