through interest groups within a larger association, several targeted conferences, and focused publications, such as the International Journal of Metadata , Semantics , and Ontologies . Despite strong, historical grounding, metadata research in data science, and the larger digital ecosystem, is restrained by not being considered a true scientific endeavor. More specifically, challenges to metadata research stem, to a large degree, from two intersecting factors: 1) the utilitarian nature of metadata, and 2) historical and traditional perceptions of metadata. 3

is the fierce competition that stems from extreme homogenization, making it difficult to generate a cluster effect and achieve collaboration effectively ( Huang, 2014 ). Therefore, methods that are solely based on technical similarities are not necessarily effective in identifying IURC partners. The method proposed in this paper is meant to improve the matching process for collaborative partners, and thereby, overcome barriers in the innovation process that prevent collaborations from forming and to encourage innovations to move along the chain. In this study, we

first year the OBRSS was implemented, 85% of academic staff updated their profiles as opposed to 75% over the previous three years. Using the publication records in CRIS, we can compare the coverage of research outputs per School and College in Scopus and the OBRSS ranked publication list. Although many international university ranking organisations use either Scopus or Web of Science as a data source to evaluate the research performance of an institution, the data source only works well for STEM (Science, Technology, Engineering & Mathematics) disciplines where

similarities between a search term and each source in the semantic network. Usually the angle (cosine similarity) between two search query vectors is calculated as the index of the similarity between these two search queries. Lucchese et al. (2011) first processed the search log, including the removal of empty log records and stop words, as well as stemming and deleting sessions that last too long or include too many queries, which indicates it is likely produced by machines. Then they calculated the word and semantic similarities between queries using two methods to

by hundreds or even thousands of authors – with papers authored by two or three researchers. It seems extremely unlikely that the intensity of close collaboration in the former case is as high as it is in the latter case. Next, we have two hypotheses regarding prediction performance: H2a: The performance of a weighted predictor is better than the performance of its unweighted counterpart. H2b: The performance of a bipartite predictor is better than the performance of both its weighted and unweighted counterpart. Hypothesis H2a stems from the fact that

-positive autistic sera were also positive for MBP autoantibodies, suggesting a strong association between MMR and Central Nervus System (CNS) autoimmunity in autism. Stemming from this evidence, we suggest that an inappropriate antibody response to MMR, specifically the measles component thereof, might be related to pathogenesis of autism” ( Singh et al., 2002 ). A second study concluded: “The higher the proportion of children receiving recommended vaccinations, the higher was the prevalence of AUT [autism] or SLI [speech language impairment]. A 1% increase in vaccination was
