“…The Wings workflow system, in particular, was developed to assist scientists in managing complex computations [7,8] and it has been used in several large-scale distributed scientific applications. For this work, we re-purposed existing workflows [9,10,11] and developed new workflows for image processing and fusion of image and text analyses.…”

Analyzing web content, particularly multimedia content, for security applications is of great interest. However, it often requires deep expertise in data analytics that is not always accessible to non-experts. Our approach is to use scientific workflows that capture expert-level methods to examine web content. We use workflows to analyze the image and text components of multimedia web posts separately, as well as by a multimodal fusion of both image and text data. In particular, we re-purpose workflow fragments to do the multimedia analysis and create additional components for the fusion of the image and text modalities. In this paper, we present preliminary work which focuses on a Human Trafficking Detection task to help deter human trafficking of minors by thus fusing image and text content from the web. We also examine how workflow fragments save time and effort in multimedia content analysis while bringing together multiple areas of machine learning and computer vision. We further export these workflow fragments using linked data as web objects.

Finally, after five years, I can finally say that I see light at the end of the tunnel. Maybe the other side is still a bit cloudy at the moment, but the important thing is to have arrived here. And, honestly, I think I wouldn't have made it to this point without all the people who have been by my side during these years.First, I would like to thank my supervisors Oscar Corcho and Yolanda Gil for guiding me whenever I got stuck and for having the patience to answer all my questions. Furthermore, thanks to their help, together with Asunción Gómez Pérez's advice, I was granted the FPU (Formación de Profesorado Universitario) scholarship from the Ministerio de Ciencia e Innovación. This scholarship has funded the internships and the research described on this document, and I am very grateful for having had the opportunity to enjoy it.I would also like to thank my family, specially my parents (Francisco Javier and María Felisa) and my sister Elisa for all their support, advice and suggestions during this period. Even from the distance! Next up are my lab mates, who have helped me with the figures (María Poveda, I really think you could write a thesis just by doing cool figures), logos (Idafen Santana, also responsible for our soccer team), technical support (Miguel Angel García and Raúl Alcázar), advice for the thesis (Andrés García and Esther Lozano) or just cheering me up when hanging out with them

“…Second, the scenario involves machine learning algorithms, and consequently a large choice of options of algorithms (and thus many exploration and update options). Lastly, we had implemented a variety of workflows in previous work (e.g., [37,44,67]) using older versions of Weka, as well as new ones using Scikit-learn and other machine learning libraries [40]. The workflows run in the WINGS [39] workflow system.…”

I would like to thank my supervisors Claudia Bauzer Medeiros at Unicamp and Yolanda Gil at the University of Southern California, for their guidance and encouragement during all this time. I will take their advices with me for the rest of my life.I owe a special thank you to my wife Flávia, who was by my side and supported me along the way, even when we were in different countries.I am grateful to my parents, who always supported my studies. My family and relatives made every moment very enjoyable in each visit or each time I went home.I also would like to thank my first supervisor, Hendrik Teixeira Macedo, who introduced me to Science during my undergraduate studies, and again as my supervisor in my Master's degree.
