Gaillard, Emmanuelle. "Gérer et exploiter des connaissances produites par une communauté en ligne : application au raisonnement à partir de cas". Electronic Thesis or Diss., Université de Lorraine, 2016. http://www.theses.fr/2016LORR0092.
Texto completo da fonteThis research work presents two approaches to improve the quality of the results returned by a case-based reasoning system (CBR) exploiting knowledge produced by an e-community. The first approach relies on a new model to manage the trustworthiness of the knowledge produced by the e community. In this model, the trustworthiness is represented through a score which is used to filter untrustworthy knowledge so that the CBR system will not use it anymore. Moreover, the trustworthiness score is also used to rank the CBR results. The second approach addresses the issue of representing the typicality between subclasses and classes in a hierarchy. The typicality is used to change the hierarchical organization used by the CBR system. Both approaches have been evaluated in the framework of eTaaable, a CBR system which adapts cooking recipes using knowledge coming from an e-community. The evaluations show that managing the trustworthiness of the knowledge produced by an e-community improves the quality of the results returned by eTaaable. The evaluations also shows that eTaaable returns also better results when using knowledge reorganized according to typicality

Texto completo da fonteWith the digital advent, it is now possible for researchers to collect important amounts of data and online social network platforms are surely part of it. Sociologists, among others, seized those new resources to investigate over interaction modalities between individuals as well as their impact on the structure of sociability. Following this lead, this thesis work aims at analyzing a large number of Facebook accounts, through data analysis and graph theory classical tools, and to bring methodological contributions. Two main factors encourage to study Facebook social activities. On one hand, the importance of time spent on this platform by many Internet users justifies by itself the sociologists interest. On the other, and contrarily to what we observe on other social network websites, ties between individuals are similar to the ones that appear offline. First, the thesis proposes to detangle the multiple meanings that are behind the fact of ”being on Facebook”. The uses of our surveyed are not compacted in fantasized normative practices but vary depending on how they appropriate the different composers of the platform tools. These uses, as we will see it, do not concern all the socioprofessional categories in the same way and they also influence how the respondents interact with their online friends. The manuscript also explores these interactions, as well as the lover role into the relational structure. Second part of the thesis builds a typology of these relational structures. They are said as egocentred, which means that they are taken from the perspective of the respondent. This typology of social networks is based on their graphlet counts, that are the number of times each type of subnetwork appear in them. This approach offers a meso perspective (between micro and macro), that is propitious to underline some new social phenomena. With a high pluri-disciplinary potential, the graphlet methodology is also discussed and explored itself

Baytok, Hazal. "Participation in Citizen Science : Motivational and Contextual Factors". Electronic Thesis or Diss., université Paris-Saclay, 2024. http://www.theses.fr/2024UPASI001.
Texto completo da fonteCitizen science is the participation of people who are not scientists in research processes such as data collection and analysis. Citizen science provides various benefits like faster and easier data collection, investigation of environmental challenges from biodiversity to climate change, as well as contributing to astronomy research and leading to collaboration between the scientists and the public.Realising the potential benefits of citizen science depends on understanding the perspectives of participants. In this study, I examine different ways of participation in citizen science and how the motivations of participants, the design of the platforms, and other factors are associated with these. The thesis contributes to our understanding of the key ingredients in designing citizen science programs so as to increase the engagement of the public.In the first part, I carried out a literature survey by bibliometric analysis. This part focuses on challenges, success factors, and motivations in citizen science. The rest of the thesis is composed of one qualitative and another quantitative study by focusing on three citizen science platforms that are actively used in the field of ornithology in two countries, Turkey and France, which are Faune-France from France, Trakuş and eKuşbank (eBird Turkey) from Turkey.In the qualitative part, through semi-structured in-depth interviews, I examine the actors, different ways of participation, motivations, and negative externalities that may arise using the Multi-Sided Platforms (MSPs) and knowledge commons literature.The results of this part helped us identify four roles in the platforms: birdwatcher, bird photographer, scientist, and hunter, interacting with each other and creating externalities.I also found two types of participation: active and passive. Regarding motivations, the findings suggested similarities in the previous studies. However, as different from previous work, I highlighted the need to distinguish motivations for engagement in the platform on the one hand and motivations for the subject matter (birds in our case) on the other.In the second part, by conducting a large-scale survey targeted at the participants of the three platforms and an econometric analysis, I examined how motivations are associated with participation, as well as the negative externalities and values created by the platform. In this part, I draw upon the Self-Determination Theory (SDT), Multi-Sided Platforms (MSPs), and negative externalities concept from the commons literature.The findings in the second part suggest that the two types of motivations identified in the first part (motivation for the subject and motivation for platform engagement) are positively associated with active and passive participation. Also, values offered by the platform and platforms' ways of addressing negative externalities have different impacts on active and passive participation based on the context, such as the participants' perceived importance of competitions positively affecting their active participation in France, whereas not having a significant impact in Turkey. Similarly, participants' perceived importance of the protection of sensitive data by the platform has a negative association with passive participation in France while being positively associated with it in Turkey. These results are important to understand the participants and to better design successful citizen science platforms

Texto completo da fonteAfter presenting the different methods to measure the power line cables propagation parameters, we justify our choice to measure these parameters up to 100 MHz using an impedance meter. Then, we validate the method of measurements and estimate these parameters on a reference cable (50 Ω cable). This phase has led us to develop a novel method for estimating propagation parameters that can overcome the measure artifacts. Afterwards, we present a comparative study on power line cable responding to the same electrical standards. This study highlights the variability of propagation: one manufacturer to another (using different dielectric), for different types (rigid versus flexible: U1000 R02V / H07 VVF) for different sections (1.5 mm² 2.5 mm²). For an optimal model is therefore essential to have the propagation parameters for the specific cable installation studied. Moreover, the grid should not be changed during installation (near the driver: cable trays, performing loops ...).The final section begins by presenting the different types of noise present on the PLC channel (time-domain and frequency-domain noise). This part allows us to present an original method for estimating the background noise of the channel less sensitive to frequency-jammers. We compare measurements on several simple network topologies with simulation results (using chain matrices). This comparison allows us to validate the method of measurement, the power line cable propagation parameter estimation, and a simple grid model. Finally, this study shows the limits of this model in the case of an actual installation. Indeed, it does not take into account e.g. the “installation parameters” or the phenomena of radiation

Texto completo da fonteThis thesis focuses on the conversion of static images of offline handwriting into temporal signals of online handwriting. Our goal is to extend neural networks beyond the scale of images of isolated letters and as well to generalize to other complex types of content. The thesis explores two distinct neural network-based approaches, the first approach is a fully convolutional multitask UNet-based network, inspired by the method of [ZYT18]. This approach demonstrated good results for skeletonization but suboptimal stroke extrac- tion. Partly due to the inherent temporal mod- eling limitations of CNN architecture. The second approach builds on the pre- vious skeletonization model to extract sub- strokes and proposes a sub-stroke level modeling with Transformers, consisting of a sub- stroke embedding transformer (SET) and a sub-stroke ordering transformer (SORT) to or- der the different sub-strokes as well as pen up predictions. This approach outperformed the state of the art on text lines and mathematical equations databases and addressed several limitations identified in the literature. These advancements have expanded the scope of offline-to-online conversion to include entire text lines and generalize to bidimensional content, such as mathematical equations

Texto completo da fonteThe aim of this thesis is to build a sentence regognition system based on an existing word regognition system. Two research axes are considered: the sentence segmentation int words as well as the integration of linguistic knowledge to take into account the context of the sentences. We studied several types of statistic language models by comparing their respective impact on the recognition system performances. We also tried to find the best strategy to introduce them efficiently into the whole recognition system. One of the originality of this study is the integration of a representation of the different sentence hypotheses in the form of a confusion network; which is then used to detect and correct the remaining regognition errors. Using the aforementioned techniques allowed us to considerably reduce the number of recognition errors among the words of the sentences
