Fully automated text mining (TM) systems promote efficient literature searching, retrieval, and review but are not sufficient to produce ready-to-consume curated documents. These meant replace biocurators, instead assist them in one or more curation steps. To do so, the user interface is an important aspect that needs be considered for tool adoption. The BioCreative Interactive task (IAT) a track designed exploring user-system interactions, promoting development of useful TM tools, providing...

In many databases, biocuration primarily involves literature curation, which usually retrieving relevant articles, extracting information that will translate into annotations and identifying new incoming literature. As the volume of biological increases, use text mining to assist in becomes increasingly relevant. A number groups have developed tools for from a computer science/linguistics perspective, there are initiatives curate some aspect biology Some efforts already make tool, but not...

A wealth of knowledge concerning relations between genes and its associated diseases is present in biomedical literature. Mining these biological associations from literature can provide immense support to research ranging drug-targetable pathways biomarker discovery. However, time cost manual curation heavily slows it down. In this current scenario one the crucial technologies text mining, relation extraction shows promising result explore with diseases. By developing automatic gene-disease...

A novel coronavirus (SARS-CoV-2) has caused a major outbreak in human all over the world. There are several proteins interplay during entry and replication of this virus human. Here, we have used text mining named entity recognition method to identify co-occurrence important COVID 19 genes/proteins interaction network based on frequency interaction. Network analysis revealed set genes/proteins, highly dense genes/protein clusters sub-networks Angiotensin-converting enzyme 2 (ACE2), Helicase,...

Abstract The timely detection and precise classification of brain tumors using techniques such as magnetic resonance imaging (MRI) are imperative for optimizing treatment strategies improving patient outcomes. This study evaluated five state‐of‐the‐art models to determine the optimal model tumor diagnosis MRI. We utilized 3064 T1‐weighted contrast‐enhanced MRI images that included gliomas, pituitary tumors, meningiomas. Our analysis employed advanced categories: machine learning classifiers,...

The present study aimed to reveal the molecular mechanism of T-2 toxin-induced cerebral edema by aquaporin-4 (AQP4) blocking and permeation. AQP4 is a class aquaporin channels that mainly expressed in brain, its structural changes lead life-threatening complications such as cardio-respiratory arrest, nephritis, irreversible brain damage. We employed dynamics simulation, text mining, vitro vivo analysis functional induced toxin on AQP4. action leads disrupted permeation water coefficients are...

Automatic extraction of protein-protein interaction (PPI) pairs from biomedical literature is a widely examined task in biological information extraction. Currently, many kernel based approaches such as linear kernel, tree graph and combination multiple kernels has achieved promising results PPI task. However, most these methods fail to capture the semantic relation between two entities. In this paper, we present special type for which exploits both syntactic (structural) vectors known...
