I did my bachelor's in Punjab, India and worked as a decision consultant for three years after at MuSigma. After that, I decided to study Data and Knowledge Engineering at the Otto-Von-Guericke University (OVGU) Magdeburg, where I finished my degree in 2022. I did a lot of research as a HiWi on Natural Language Processing and Time Series Prediction. In addition, I worked as a Machine Learning, Data Mining and Deep Learning tutor for several terms. Currently, I am pursuing my PhD at the DZHW in cooperation with the OVGU.

WISHFUL - Website extraction of Institutional Sources with Heterogeneous Factors and User-Driven Linkage.Shahania, S., Spiliopoulou, M., & Broneske, D. (2023).WISHFUL - Website extraction of Institutional Sources with Heterogeneous Factors and User-Driven Linkage. In Delir Haghighi, P. et al. (Hrsg.), Information Integration and Web Intelligence (iiWAS 2023) (S. 20-26). Cham: Springer. https://doi.org/10.1007/978-3-031-48316-5_3 Abstract
Extracting information from diverse websites is increasingly important, especially for analyzing vast data sets to detect trends, gain insights. By studying job ads, researchers can monitor employer demand shifts, assisting policymakers in aiding affected workers and industries. However, extraction faces challenges like varied website formats, dynamic content, and duplicate data. This study introduces a method for extracting data from diverse private university websites involving keyword identification, website categorization, and extraction pipelines. |

Tell me why it’s fake: Developing an explainable user interface for a fake news detection system.Shahania, S., Purificato, E., & William De Luca, E. (2022).Tell me why it’s fake: Developing an explainable user interface for a fake news detection system. In CEUR Workshop Proceedings (Hrsg.), Proceedings of the 3rd Italian Workshop on Explainable Artificial Intelligence (XAI.it 2022). Udine, Italy: CEUR. Abstract
In this paper, we present the design and development of an explainable user interface for a fake news detection system. The problem of distinguishing real from fake articles gained a lot of popularity in the last few years, mainly due to the soaring diffusion of social networks and internet bots as means for propaganda and disinformation sharing. By leveraging various explainability methods, i.e. feature importance, partial dependence plots and SHAP values, we aim to show how the combination of different techniques embedded in an interactive user interface can lead to enhance trust in a detection system for a non-expert user, such as a fact-checker or a content manager. Through several examples, we describe all the explainability component |

Legal norm retrieval with variations of the bert model combined with TF-IDF vectorization.Wehnert, S., Sudhi, V., Dureja, S., Kutty, L., Shahania, S., & W. De Luca, E. (2021).Legal norm retrieval with variations of the bert model combined with TF-IDF vectorization. In Association for Computing Machinery (Hrsg.), ICAIL '21: Proceedings of the Eighteenth International Conference on Artificial Intelligence and Law, São Paulo, Brazil (S. 285-294). New York, NY, United States: Association for Computing Machinery. https://doi.org/10.1145/3462757.3466104 Abstract
In this work, we examine variations of the BERT model on the statute law retrieval task of the COLIEE competition. This includes approaches to leverage BERT's contextual word embeddings, fine-tuning the model, combining it with TF-IDF vectorization, adding external knowledge to the statutes and data augmentation. Our ensemble of Sentence-BERT with two different TF-IDF representations and document enrichment exhibits the best performance on this task regarding the F2 score. This is followed by a fine-tuned LEGAL-BERT with TF-IDF and data augmentation and our third approach with the BERTScore. We show that there are significant differences between the chosen BERT approaches and discuss several design decisions in the context of statute law. |
