This paper adopts the use of the diffusion maps method for joining long string values, such as paper abstracts, movie summaries, product descriptions, and user feedback, to improve the performance of the existing similarity join methods. In this work, we showed that using attributes of long string values to detect similar records would significantly improve the overall similarity join performance...
In this paper, we propose a pre-processing technique to improve existing string similarity join algorithms using fuzzy clustering. Our approach first identifies groups of related attributes and then, using this information, we apply existing string similarity join algorithms on these attributes. To identify the clustered attributes we use fuzzy techniques. This approach can be applied to the integration...
This paper describes a method and system for monitoring and correlating digitized non-verbal data (like emotions and eye-gaze) with other kinds of data for decision support and information personalization. This is illustrated through two applications in this paper. The first one describes detection, monitoring and correlation of emotional state changes for behavior profiling of sales candidates. The...
String is a primary data format in majority of applications. With the rapid growth of diverse data driven applications in the current information era, retrieving string data from heterogeneous structured sources becomes more and more significant and challenging. The main concern is duplicate records are created when data is integrated from heterogeneous sources. Those duplicate records represent the...
We present a virus detection-and-removal service architecture for digital ecosystems which is inspired by biological ecosystems. This service becomes active as soon as a virus infection of a machine is identified. In a biological ecosystem, as a virus is found to be active, all organisms infected by it need to be identified and treated. In some cases, if they cannot be treated, the only option left...
Video frame rate conversion is often recognized as video temporal interpolation. In this paper, a region-based approach to automated video frame rate conversion is presented. The region extraction is performed by spatially dividing the reference video frames. Since this step involves image segmentation, the resulting regions are under or over segmented. Consistent frame to frame region extraction...
We proposed a temporal object system (TOS) which maintains changes to both the structure and the state of an object in a temporal fashion. Objects in TOS are referred to as temporal objects and are allowed to evolve over time. A collection of temporal objects which share the same set of common properties is grouped into a family. A temporal object that can be defined by using the local knowledge of...
Temporal Object System (TOS) handles the structural and stature changes to an object in a uniform and temporal fashion. The TOS takes a hybrid approach of the class-based and prototype-based approaches in modeling the real-word objects and knowledge sharing among the objects. This hybrid approach makes it flexible than the two approaches, i.e., the class-based approach and the prototype-based approach...
