A null model to detect coordinated online behavior integrating evidence from multiple indicators
Filipi Nascimento Silva, Manita Pote, Lake Yin +5
Coordinated online accounts can amplify messages and manipulate attention, but detecting such behavior is challenging due to confounding factors like account activity and item popu…
Comparing biased random walks in graph embedding and link prediction
Adilson Vital, Filipi N. Silva, Diego R. Amancio
Random walks find extensive application across various complex network domains, including embedding generation and link prediction. Despite the widespread utilization of random wal…
Identifying the perceived local properties of networks reconstructed from biased random walks
Lucas Guerreiro, Filipi N. Silva, Diego R. Amancio
Many real-world systems give rise to a time series of symbols. The elements in a sequence can be generated by agents walking over a networked space so that whenever a node is visit…
Recovering network topology and dynamics via sequence characterization
Lucas Guerreiro, Filipi N. Silva, Diego R. Amancio
Sequences arise in many real-world scenarios; thus, identifying the mechanisms behind symbol generation is essential to understanding many complex systems. This paper analyzes sequ…
A comparative analysis of knowledge acquisition performance in complex networks
Lucas Guerreiro, Filipi N. Silva, Diego R. Amancio
Discovery processes have been an important topic in the network science field. The exploration of nodes can be understood as the knowledge acquisition process taking place in the n…
A complex network approach to political analysis: application to the Brazilian Chamber of Deputies
Ana C. M. Brito, Filipi N. Silva, Diego R. Amancio
In this paper, we introduce a network-based methodology to study how clusters represented by political entities evolve over time. We constructed networks of voting data from the Br…
The Dynamics of Knowledge Acquisition via Self-Learning in Complex Networks
Thales S. Lima, Henrique F. de Arruda, Filipi N. Silva +3
Studies regarding knowledge organization and acquisition are of great importance to understand areas related to science and technology. A common way to model the relationship betwe…
Knowledge Acquisition: A Complex Networks Approach
Henrique F. de Arruda, Filipi N. Silva, Luciano da F. Costa +1
Complex networks have been found to provide a good representation of the structure of knowledge, as understood in terms of discoverable concepts and their relationships. In this co…
Using network science and text analytics to produce surveys in a scientific topic
Filipi N. Silva, Diego R. Amancio, Maria Bardosova +2
The use of science to understand its own structure is becoming popular, but understanding the organization of knowledge areas is still limited because some patterns are only discov…
