An Event Graph Model for Discovering Trends from Text Streams
نویسندگان
چکیده
In this paper, we formally define and study the event graph model based on set theory and multi-relations theory, and discuss the methods of modeling event and event relations in detail. The event graph model is mainly designed to extract the potential events and the relationships between events from massive text streams, and further discover the trends embodied in the contents in text streams. We also study the connectivity of the event graph model, and give the equivalent conditions to determine the connectivity of event graph.

Early detection and precise characterization of emerging topics in text streams can be highly useful in applications such as timely and targeted public health interventions and discovering evolving regional business trends. Many methods have been proposed for detecting emerging events in text streams using topic modeling. However, these methods have numerous shortcomings that make them unsuitab...
متن کاملMining Social Streams: Models and Applications
Online social networks are rich in terms of structural connections between entities and the content propagated between them. When this data is available as a continuous stream of interactions on the social graph, it is referred to as a social stream. Social streams have several challenges: (1) size of the underlying graph, (2) volume of the interactions, and (3) heterogeneity of the content and...

Temporal Text Mining (TTM) is concerned with discovering temporal patterns in text information collected over time. Since most text information bears some time stamps, TTM has many applications in multiple domains, such as summarizing events in news articles and revealing research trends in scientific literature. In this paper, we study a particular TTM task – discovering and summarizing the ev...
متن کاملEvent Detection and Visualization for Social Text Streams
In this paper, we propose to detect events from social text streams by exploring the content as well as the temporal, and social dimensions. We define the term event in the social text streams(e.g., blogs, emails, and Usenets) as a set of relations between social actors on a specific topic over a certain time period. We represent social text streams as multi-graphs, where each node represents a...
متن کاملEvent Intensity Tracking in Weblog Collections
Event tracking is the task of discovering temporal patterns of events from text streams. Existing approaches for event tracking have two limitations: scalability and their inability to rule out non-relevant portions within texts in the stream ‘relevant’ to the event of interest. In this study, we propose a novel approach to tackle these limitations. To demonstrate our approach, we track news ev...
