Sentiment and structure in word co-occurrence networks on Twitter [PDF]
Applied Network Science, 2022 AbstractWe explore the relationship between context and happiness scores in political tweets using word co-occurrence networks, where nodes in the network are the words, and the weight of an edge is the number of tweets in the corpus for which the two connected words co-occur.

Fluvial network organization imprints on microbial co-occurrence networks [PDF]
Proceedings of the National Academy of Sciences, 2014 Significance Microbial communities orchestrate most biogeochemical processes on Earth. In streams and rivers, surface-attached and matrix-enclosed biofilms dominate microbial life. Despite the relevance of these biofilms for ecosystem processes (e.g., metabolism and nutrient cycling), it remains unclear how features inherent to stream

Empirical Co-occurrence Rate Networks for Sequence Labeling [PDF]
2013 12th International Conference on Machine Learning and Applications, 2013 Structured prediction has wide applications in many areas. Powerful and popular models for structured prediction have been developed. Despite the successes, they suffer from some known problems: (i) Hidden Markov models are generative models which suffer from the mismatch problem.

Difficulty in inferring microbial community structure based on co-occurrence network approaches
BMC Bioinformatics, 2019 Background Co-occurrence networks—ecological associations between sampled populations of microbial communities inferred from taxonomic composition data obtained from high-throughput sequencing techniques—are widely used in microbial ecology.

Co-occurrence network of TV advertisements revealing Japanese lifestyle
Applied Network Science, 2021 The relationship between culture and the appeals in TV advertisements has been extensively studied. We attempted to reveal the image structure produced by TV commercials in Japan, which may show the cultural features of the country, and to evaluate its ...

Inferring microbial co-occurrence networks from amplicon data: a systematic evaluation
mSystems, 2023 Microbes commonly organize into communities consisting of hundreds of species involved in complex interactions with each other. 16S ribosomal RNA (16S rRNA) amplicon profiling provides snapshots that reveal the phylogenies and abundance profiles of these

Topic Network Analysis Based on Co-Occurrence Time Series Clustering
Mathematics, 2022 Traditional topic research divides similar topics into the same cluster according to clustering or classification from the perspective of users, which ignores the deep relationship within and between topics. In this paper, topic analysis is achieved from
