Streams of user-generated content in social media exhibit patterns of collective attention across diverse topics, with temporal structures determined both by exogenous factors and endogenous factors. Teasing apart different topics and resolving their individual, concurrent, activity timelines is a key challenge in extracting knowledge from microblog streams. Facing this challenge requires the u...

Many sensor network applications are concerned with discovering interesting patterns among observed real-world events. Often, only limited apriori knowledge exists about the patterns to be found eventually. Here, raw streams of sensor readings are collected at the sink for later offline analysis – resulting in a large communication overhead. In this paper, we explore the use of in-network data ...

In the paper a detailed analysis of the dynamic response of a cooling tower shell to mining tremors originated from two main regions of mining activity in Poland (Upper Silesian Coal Basin and Legnica-Glogow Copper District) was presented. The representative time histories registered in the both regions were used as ground motion data in calculations of the dynamic response of the structure. It...

The activity of reengineering and maintaining large legacy systems involves the use of design recovery techniques to produce abstractions that facilitate the understanding of the system. In this paper, we present an approach to design recovery based on data mining. This approach derives from the observation that data mining can discover unsuspected non-trivial relationships among elements in la...

Motion information has been widely exploited for group activity recognition in sports video. However, order to model and extract the various motion between adjacent frames, existing algorithms only use coarse video-level labels as supervision cues. This may lead ambiguity of extracted features omission changing rules patterns that are also important video recognition. In this paper, a latent la...

-.Internet is today full of structured or unstructured information. and this information is directly or indirectly influencing society or peoples. Because today internet is part our daily life activity. But using this abundant and ambiguous in most efficient manner in useful decision making is still a big challenge. During our web surfing either it is online shopping or blogging or using tweets...
