ODAC: Hierarchical Clustering of Time Series Data Streams
This paper presents a time series whole clustering system that incrementally constructs a tree-like hierarchy of clusters, using a top-down strategy. The Online Divisive-Agglomerative Clustering (ODAC) system uses a correlation-based dissimilarity measure between time series over a data stream and possesses an agglomerative phase to enhance a dynamic behavior capable of concept drift detection....
متن کاملAn Empirical Comparison of Distance Measures for Multivariate Time Series Clustering
Multivariate time series (MTS) data are ubiquitous in science and daily life, and how to measure their similarity is a core part of MTS analyzing process. Many of the research efforts in this context have focused on proposing novel similarity measures for the underlying data. However, with the countless techniques to estimate similarity between MTS, this field suffers from a lack of comparative...
متن کاملL2 Learners’ Use of Metadiscourse Markers in Online Discussion Forums
This study aimed to investigate the use of interactional metadiscourse markers in 168 comments made by 28 university students of engineering via an educational forum held as part of a general English course. The students wrote their comments on six topics, with a total of 19,671 words. Their comments during educational discussions were analyzed to determine their use of five metadiscourse categ...
متن کاملClustering of Time-Series Data Streams
This paper presents a time-series whole clustering system that incrementally constructs a tree-like hierarchy of clusters. The Online DivisiveAgglomerative Clustering (ODAC) system uses a correlation-based similarity measure between time-series over a data stream. When turning a leaf into a node, the cluster is divided in two and new leaves start new computations. An agglomerative phase is used...
متن کاملViral Marketing in an Online Discussion Forum
Online opinion leaders play an important role in the dissemination of information in discussion forums. They are a high-priority target group for viral marketing campaigns. On an average, an opinion leader will tell about his or her experience with a product or company to 14 other people. It is important to identify such opinion leaders from data derived from online activity of users. We presen...
