“…Leskovec et al [8] propose a framework for tracking short phrases ("memes") across mainstream media sites, and to study the diffusion dynamics of the news cycle. Similar techniques enable the tracking of emerging trends on social and mainstream media [6], [9] and the study of the dynamics of diffusion process across different kinds of topics [12].…”

Abstract-We study the data mining problem of modeling adoptions and the stages of the diffusion of an innovation. For our aim we propose a stochastic model which decomposes a diffusion trace (sequence of adoptions) in an ordered sequence of stages, where each stage is intuitively built around two dimensions: users and relative speed at which adoptions happen. Each stage is characterized by a specific rate of adoption and it involves different users to different extent, while the sequentiality in the diffusion is guaranteed by constraining the transition probabilities among stages.An empirical evaluation on synthetic and real-world adoption logs shows the effectiveness of the proposed framework in summarizing the adoption process, enabling several analysis tasks such as the identification of adopter categories, clustering and characterization of diffusion traces, and prediction of which users will adopt an item in the next future.

“…A set of DTVs can be aggregated together to obtain a set centroid for the corresponding documents, which can be used to summarize the document set. Given the centroid, a system can produce other summary measures, such as a representative set of "bursty" terms [19,37], the medoid [9,18], or a diverse set of representative documents [12].…”

Partial materialization for online analytical processing over multi-tagged document collections

The New York Times Annotated Corpus, the ACM Digital Library, and PubMed are three prototypical examples of document collections in which each document is tagged with keywords or phrases. Such collections can be viewed as high-dimensional document cubes against which browsers and search systems can be applied in a manner similar to online analytical processing against data cubes. After examining the tagging patterns in these collections, a partial materialization strategy is developed to provide efficient storage and access to centroids for document subsets that are defined through queries over tags. By adopting this strategy, summary measures dependent on centroids (including measures involving medoids, sets of representative documents, or sets of representative terms) can be efficiently computed. The proposed design is evaluated on the three collections and on several synthetically generated collections to validate that it outperforms alternative storage strategies.
