Corpus linguistics investigates language using extensive text databases. Tools assist researchers in analyzing, extracting, and interpreting linguistic information efficiently. Furthermore, if only use traditional tools corpus analysis, they will lack the comprehensiveness efficiency required to effectively navigate derive valuable insights from data. This paper employed preferred reporting items for systematic reviews meta-analyses (PRISMA) approach find primary data based on a few keywords linguistic, computational corpora tool support. Based this method, we used advanced searching techniques Scopus Web of Science (WoS) discovered (N=28) pertinent study. Expert scholars decide theme problem, which is (i) types their uses; (ii) contributions capabilities (iii) limitations tools. All were interdisciplinary studies. In summary, review uncovers pivotal key findings at intersection enriching knowledge. It highlights potential corpus-based analysis advancing and, applications, as well analysis.

In his book 'A Beautiful Question', physicist Frank Wilczek argues that symmetry is 'nature's deep design,' governing the behavior of universe, from smallest particles to largest structures. While a cornerstone physics, it has not yet been found widespread applicability describe biological systems, particularly human brain. this context, we study brain network engaged in language and explore relationship between structural connectivity (connectome or network) emergent synchronization mesoscopic regions interest (functional network). We explain through different kind than physical symmetry, derived categorical notion Grothendieck fibrations. This introduces new understanding by proposing local theory connectome, which accounts for how structure brain's determines its coherent activity. Among allowed patterns connectivity, elicits subsets according functional engagement show resting state particular realization cerebral pattern characterized fibration broken transition rest language. Our findings suggest at level function, can understand theoretical principles.

Abstract Understanding the relative contribution of various factors influencing initial severity aphasia and recovery after a stroke is essential for optimising neurorehabilitation programmes. We investigated how significant sociodemographic, cognitive, clinical, stroke‐related rehabilitation‐related modulate language following left‐hemispheric stroke. Employing an innovative method, we conducted retrospective analysis 96 participants to explore combined impact these factors. The was categorised into severe, mild/moderate no based on their deficits in subacute phase (Aphasia Severity Rating Scale, ASRS). To assess speech‐and‐language recovery, classified 53/96 patients with high poor categories using gain score formula (ASRS_discharge—ASRS_admission)/ASRS_admission. Subsequently, performed statistical analyses (univariate forward stepwise logistic regression bootstrap) identify determinants degree recovery. Our unveiled that more severe initially correlated (Odds Ratio, OR = .90, p .041), moderate/severe executive dysfunction (OR .068, < .001) larger lesion size .001). Furthermore, associated intensity therapy 1.47, .043). These findings enrich our understanding employing original methodology scrutinise collective effect multiple variables participants.

Hemispheric specialization is a fundamental feature of human brain organization. However, it not yet clear to what extent the lateralization specific cognitive processes may be evident throughout broad functional architecture cortex. While majority people exhibit left-hemispheric language dominance, substantial minority population shows reverse lateralization. Using twin and family data from Human Connectome Project, we provide evidence that atypical dominance associated with global shifts in cortical Individuals organization exhibited corresponding hemispheric differences macroscale gradients situate discrete large-scale networks along continuous spectrum, extending unimodal through association territories. Analyses revealed both gradient asymmetries are, part, driven by genetic factors. These findings pave way for deeper understanding origins relationships linking population-level variability properties
