Knowledge graph embeddings provide powerful latent semantic representation for the structured knowledge in knowledge graphs, which have been introduced recently. Being different from the already widely-used word embeddings that are conceived from plain text, knowledge graph embeddings enable direct explicit relational inferences among entities via simple calculation of embedding vectors. In par...

OBJECTIVE To examine internal construct validity of the Neurobehavioral Functioning Inventory (NFI) by applying Rasch analysis. SETTING An outpatient rehabilitation program trial in New Zealand employing a goal-setting intervention in people with traumatic brain injury (TBI). PARTICIPANTS One hundred eight people (mean age = 46 years; 73% male) between 6 months and 5 years post-TBI. DESIG...

BACKGROUND Little research has assessed the degree of severity and ordering of different types of sexual behaviors for HIV/STI infection in a measurement scale. The purpose of this study was to apply the Rasch model on psychometric assessment of an HIV/STI sexual risk scale among men who have sex with men (MSM). METHODS A cross-sectional study using respondent driven sampling was conducted am...

In the last few years, Twitter has become a powerful tool for publishing and discussing information. Yet, content exploration in Twitter requires substantial efforts and users often have to scan information streams by hand. In this paper, we approach this problem by means of faceted search. We propose strategies for inferring facets and facet values on Twitter by enriching the semantics of indi...

AIM The aim of this study was to test and improve the unidimensionality and item hierarchy of the Modified House Classification (MHC) for the assessment of upper limb capacity in children with unilateral cerebral palsy (CP) using Rasch analysis. The construct validity of the Rasch-reduced item set was evaluated. METHOD Modified House Classification items were scored from 369 videotaped assess...

Background: Cloud-native software systems often have a much more decentralized structure and many independently deployable (horizontally) scalable components, making it complicated to create shared consolidated picture of the overall system state. Today, observability is understood as triad collecting processing metrics, distributed tracing data, logging. The result complex composed three stove...

We present a comprehensive study of the variability properties young disk-bearing stars in Taurus star-forming region, paralleling our previous investigation rho Oph and Upper Sco. A sample 99 confirmed association members is placed diagnostic Q-M plane flux asymmetry (M) quasi-periodicity (Q), which guides assignment classes. find similar proportion flux-symmetric variables Taurus, but more bu...

We performed a Rasch analysis of cross-sectional developmental data gathered from children and adults who were presented with a task series derived from Inhelder's and Piaget's balance beam. The partial credit model situates both participants and items along a single hierarchically ordered dimension. As the Model of Hierarchical Complexity predicted, order of hierarchical complexity accurately ...

PURPOSE To validate the Sumi Visual Disability Questionnaire (Sumi VDQ) to estimate visual disability in glaucoma patients using Rasch analysis. METHODS A total of 162 glaucoma patients underwent visual field (VF) testing in both eyes (Humphrey 24-2 Swedish Interactive Threshold Algorithm [SITA] standard program). The binocular VF was then calculated using the integrated VF (IVF) method. Visu...

Faceted search represents one of the most practical ways to browse a large corpus of information. Information is categorized automatically for a given query and the user is given the opportunity to further refine his/her query. Many search engines offer a powerful faceted search engine, but only on the textual level. Faceted Search in the context of Math Search is still unexplored territory. In...
