Abstract Motivation The COVID-19 pandemic has prompted an impressive, worldwide response by the academic community. In order to support text mining approaches as well data description, linking and harmonization in context of COVID-19, we have developed ontology representing major novel coronavirus (SARS-CoV-2) entities. a strong scope on chemical entities suited for drug repurposing, this is target ongoing therapeutic development. Results comprises 2270 classes concepts 38 987 axioms (2622...

Abstract Motivation The importance of clinical data in understanding the pathophysiology complex disorders has prompted launch multiple initiatives designed to generate patient-level from various modalities. While these studies can reveal important findings relevant disease, each study captures different yet complementary aspects and modalities which, when combined, a more comprehensive picture disease etiology. However, achieving this requires global integration across studies, which proves...

Schizophrenia and bipolar disorder are characterized by highly similar neuropsychological signatures, implying shared neurobiological mechanisms between these two disorders. These disorders also have comorbidities, such as type 2 diabetes mellitus (T2DM). To date, an understanding of the that mediate link remains incomplete. In this work, we identify investigate patterns across multiple schizophrenia, T2DM gene expression datasets through strategies. Firstly, dysregulation at gene-level...

Abstract Motivation Epilepsy is a multifaceted complex disorder that requires precise understanding of the classification, diagnosis, treatment and disease mechanism governing it. Although scattered resources are available on epilepsy, comprehensive structured knowledge missing. In contemplation to promote multidisciplinary exchange facilitate advancement in clinical management, especially pre-clinical research, disease-specific ontology necessary. The presented designed enable better...

Although hundreds of datasets have been published since the beginning coronavirus pandemic, there is a lack centralized resources where these are listed and harmonized to facilitate their applicability uptake by predictive modeling approaches. Firstly, such resource provides information about data owners researchers who searching develop models. Secondly, harmonization supports simultaneously taking advantage several similar datasets. This, in turn, does not only ease imperative external...

As one of the leading causes for dementia in population, it is imperative that we discern exactly why Alzheimer's disease (AD) has a strong molecular association with beta-amyloid and tau. Although clear understanding about etiology pathogenesis AD remains unsolved, scientists worldwide have dedicated significant efforts to discovering interactions linked pathological characteristics potential treatments. Knowledge representations, such as domain ontologies encompassing our current AD, could...
