Abstract
A method of performing a semantic textual similarity search between a target document and a set of source documents includes: selecting target textual data from the target document; identifying and classifying, name entities for each textual sequence of the target textual data; generating, a semantic textual similarity model and using the semantic textual similarity model to generate textual embedding of the identified name entities for each textual sequence of the target textual data; aggregating the textual embedding with the structural features of the target textual data to generate target document embedding; searching, by a similarity estimator, for similar documents by measuring similarities of the target document embedding with embeddings of each source document of the set of source documents; and computing explanatory information about a degree of similarity between the target document and any document of the set of the source documents.
