  This paper provides an insight into the possibility of how to find ontologies
most relevant to scientific texts using artificial neural networks. The basic
idea of the presented approach is to select a representative paragraph from a
source text file, embed it to a vector space by a pre-trained fine-tuned
transformer, and classify the embedded vector according to its relevance to a
target ontology. We have considered different classifiers to categorize the
output from the transformer, in particular random forest, support vector
machine, multilayer perceptron, k-nearest neighbors, and Gaussian process
classifiers. Their suitability has been evaluated in a use case with ontologies
and scientific texts concerning catalysis research. From results we can say the
worst results have random forest. The best results in this task brought support
vector machine classifier.
