Guélorget, Paul. « Active learning for the detection of objects of operational interest in open-source multimedia content ». Electronic Thesis or Diss., Institut polytechnique de Paris, 2022. http://www.theses.fr/2022IPPAS018.
Texte intégralA profusion of openly accessible content, actors and interactions is targeted by analysts for intelligence, marketing or political purposes. Analysing the immensity of open source data requires automated assistance. Although recent propositions in neural network architectures have demonstrated strong capacities for image and text modalities, their training harnesses massive training datasets, non-existent for the majority of operational classes of interest. To address this issue, active learning takes advantage of the great amounts of unlabelled documents by soliciting from a human oracle the ground-truth labels of the presumed most informative documents, to improve accuracy. Yet, the model's decision-making rationales are opaque and might be unrelated to those of the oracle. Furthermore, with its time-consuming iterative steps, the active learning workflow is detrimental to its real-time performances. Our contributions in this thesis aim to analyse and address these issues at four levels. Firstly, we observe the rationales behind a neural network's decisions. Secondly, we put these rationales into perspective with human rationales. Thirdly, we try and make the neural network align its decision-making rationales with those of a teacher model to simulate the rationales of a human oracle and improve accuracy in what is called active learning with rationales. Finally, we design and exploit an active learning framework to overcome its usual limitations. These studies were conducted with uni-modal text and image data, and multi-modal text and image associations, principally press articles in English and French. Throughout this work's chapters, we address several use cases among which fake news classification, vagueness classification, the detection of lack of contradiction in articles, the detection of arbitrary topics such as demonstrations and violence

Texte intégralDue to the considerable increase of freely available data (especially on the Web), the discovery of relevant information from textual content is a critical challenge. Open Source Intelligence (OSINT) specialists are particularly concerned by this phenomenon as they try to mine large amounts of heterogeneous information to acquire actionable intelligence. This collection process is still largely done by hand in order to build knowledge sheets summarizing all the knowledge acquired about a specific entity. Given this context, the main goal of this thesis work is to reduce and facilitate the daily work of intelligence analysts. For this sake, our researches revolve around three main axis: knowledge modeling, text mining and knowledge gathering. We explored the literature related to these different domains to develop a global knowledge gathering system. Our first contribution is the building of a domain ontology dedicated to knowledge representation for OSINT purposes and that comprises a specific definition and modeling of the event concept for this domain. Secondly, we have developed and evaluated an event recognition system which is based on two different extraction approaches: the first one is based on hand-crafted rules and the second one on a frequent pattern learning technique. As our third contribution, we proposed a semantic aggregation process as a necessary post-processing step to enhance the quality of the events extracted and to convert extraction results into actionable knowledge. This is achieved by means of multiple similarity measures between events, expressed according a qualitative scale which has been designed following our final users' needs

Texte intégralUnderstanding the dynamics of a conflict in order to anticipate its evolution is of major interest for open source military intelligence (OSINT) and police intelligence, particularly in the context of Intelligence Led Policing. If the ambition to predict the events of a conflict is not realistic, the ambition to detect them is an important and achievable objective. The human and social sciences, particularly the information and communication sciences combined with the science of data and documents, make it possible to exploit digital social networks in such a way as to make event detection and monitoring a more appropriate objective and method than the standard "protest event analysis" in the context of modern wars and the connected society. At the same time, this requires a renewed intelligence cycle.Based on data from the social network Twitter, collected during the Ukrainian crisis, this thesis shows the relevance of conflict detection and monitoring using our DETEVEN method. This method not only identifies relevant events in a conflict, but also facilitates their monitoring and interpretation. It is based on the detection of statistical anomalies and the adaptation of protest event analysis to social media. Our method is particularly effective on what we define as connected theatres of operation (CTOs) characteristic of new hybrid warfare contexts and on operations of misinformation or influence. These detected events were analytically exploited using a platform designed for an analyst, allowing effective data visualization. In a crisis situation, especially in a "social movement war", where each user becomes a de facto social sensor, information control is a strategic issue. This thesis therefore shows how information literacy is an important issue for individuals and groups

Texte intégralDue to the massive and progressive deployment of video surveillance systems in major cities, a posteriori analysis of videos coming from these systems is facing many problems, including the following: (i) interoperability, due to the different data (video) formats and camera specifications associated to each system; (ii) time-consuming nature of analysis due to the huge amount of data and metadata generated; and (iii) difficulty to interpret videos which are sometimes incomplete. To address these issues, the need to propose a common format to exchange video surveillance data and metadata, to make video content filtering and querying more efficient, and to facilitate the interpretation of content using external (contextual) information is an unavoidable concern. Therefore, this thesis focuses on heterogeneous and multi-source metadata modeling in order to propose negative filtering and intelligent data querying, which are applicable to video surveillance systems in particular and adaptable to systems dealing with large volumes of data in general. In the applicative context of this thesis, the goal is to provide human CCTV operators with tools that help them to reduce the large volume of video to be processed or viewed and implicitly reduce search time. We therefore initially propose a so-called "negative" filtering method, which enables the elimination from the mass of available videos those that it is know in advance, based on a set of criteria, that the processing will not lead to any result. The criteria used for the proposed negative filtering approach are based on metadata modeling describing video quality and usability/usefulness. Then, we propose a contextual enrichment process based on metadata from the context, enabling intelligent querying of the videos. The proposed contextual enrichment process is supported by a scalable metadata model that integrates contextual information from a variety of sources, and a multi-level query mechanism with a spatio-temporal reasoning ability that is robust to fuzzy queries. Finally, we propose a generic metadata modeling of video surveillance metadata integrating metadata describing the movement and field of view of cameras, metadata from content analysis algorithms, and metadata from contextual information, in order to complete the metadata dictionary of the ISO 22311/IEC 79 standard, which aims to provide a common format to export data extracted from video surveillance systems. The experiments performed using the framework developed in this thesis showed the reliability of our approach in a real case and enabled the validation of our proposals
