Department of Hepatogastroenterology and Proctology Medicine B, Ibn Sina University Hospital Center, Mohamed V University of Rabat, Rabat, Morocco.

Squamous cell carcinoma (SCC) of the stomach is a rare entity with fewer than 100 cases of primary SCC reported in the literature, while esophageal SCC is prevalent and more common. However, a synchronous squamous cell carcinoma found in the esophagus and stomach remains very uncommon. We present the case of a 64-year-old with a history of dysphagia who had an endoscopy that showed an impassable stenosis of the middle esophagus, with histopathology in favor of an esophagus squamous cell carcinoma.

A step towards quantifying, modelling and exploring uncertainty in biomedical knowledge graphs.

Comput Biol Med

January 2025

International University of Rabat, TICLab, Sala el Jadida 11103, Morocco; University of Leeds, Faculty of Engineering, University of Leeds, Leeds LS2 9JT, UK. Electronic address:

Objective: This study aims at automatically quantifying and modelling the uncertainty of facts in biomedical knowledge graphs (BKGs) based on their textual supporting evidence using deep learning techniques.

Materials And Methods: A sentence transformer is employed to extract deep features of sentences used to classify sentence factuality using a naive Bayes classifier. For each fact and its supporting evidence in a source KG, the deep feature extractor and the classifier are used to quantify the factuality of each sentence which are then transformed to numerical values in [0,1] before being averaged to get the confidence score of the fact.
