Structure-semantics interplay in complex networks and its effects on the predictability of similarity in texts
Diego R. Amancio, Osvaldo N. Oliveira, Luciano da F. Costa
There are different ways to define similarity for grouping similar texts into clusters, as the concept of similarity may depend on the purpose of the task. For instance, in topic e…
On the use of topological features and hierarchical characterization for disambiguating names in collaborative networks
Diego R. Amancio, Osvaldo N. Oliveira, Luciano da F. Costa
Many features of complex systems can now be unveiled by applying statistical physics methods to treat them as social networks. The power of the analysis may be limited, however, by…
Complex networks analysis of language complexity
Diego R. Amancio, Sandra M. Aluisio, Osvaldo N. Oliveira +1
Methods from statistical physics, such as those involving complex networks, have been increasingly used in quantitative analysis of linguistic phenomena. In this paper, we represen…
Unveiling the relationship between complex networks metrics and word senses
Diego R. Amancio, Osvaldo N. Oliveira, Luciano da F. Costa
The automatic disambiguation of word senses (i.e., the identification of which of the meanings is used in a given context for a word that has multiple meanings) is essential for su…
Using Complex Networks to Quantify Consistency in the Use of Words
Diego R. Amancio, Osvaldo N. Oliveira, Luciano da F. Costa
In this paper we quantify the consistency of word usage in written texts represented by complex networks, where words were taken as nodes, by measuring the degree of preservation o…
Three-feature model to reproduce the topology of citation networks and the effects from authors' visibility on their h-index
Diego R. Amancio, Osvaldo N. Oliveira, Luciano da F. Costa
Various factors are believed to govern the selection of references in citation networks, but a precise, quantitative determination of their importance has remained elusive. In this…
