Outlier Recognition via Linguistic Aggregation of Graph Databases

open access: yesApplied Sciences, 2021
Datasets frequently contain uncertain data that, if not interpreted with care, may affect information analysis negatively. Such rare, strange, or imperfect data, here called “outliers” or “exceptions” can be ignored in further processing or, on the other

Some problems on graph databases

open access: yesТруды Института системного программирования РАН, 2018
Graph databases appear to be the most popular and relevant among non-relational databases. Its popularity is caused by its relatively easy implementation in the problems in which data have big numbers of relations such as protein-protein interaction and ...

Mining Frequent Neighborhood Patterns in Large Labeled Graphs [PDF]

open access: yes, 2013
Over the years, frequent subgraphs have been an important sort of targeted patterns in the pattern mining literatures, where most works deal with databases holding a number of graph transactions, e.g., chemical structures of compounds. These methods rely
