TL;DR: In this paper, a working definition of Digital Twins is proposed and the state-of-the-art in the three topics in their relation to DTs are examined, along with potentials for each topic mapped against the working definition.

TL;DR: A distributed index mechanism where each peer is provided with a Semantic Routing Index (SRI) for routing queries effectively is proposed and a fuzzy-oriented model for SRI is presented where operations for creating and maintaining SRIs are well-founded.

TL;DR: This paper proposes a solution based on a purely syntactic approach for searching similarities within sentences, named approximate sub2sequence matching, that allows us to deploy approximate sub 2 sequence matching without changing the underlying database.

TL;DR: In this article, the problem of effective search and query answering in heterogeneous web document bases containing documents in XML format of which the schemas are available is dealt with, where a new solution is proposed for the structural approximation of the submitted queries which, in a preliminary schema matching process, is able to automatically identify the similarities between the involved schemas and to use them in the query processing phase, when a query written on a source schema is automatically rewritten in order to be compatible with the other useful XML documents.
