Information visualization techniques have been applied to many research fields in recent years. This paper introduces the concept of visual signature for financial time series. Unlike other information visualization, visual signatures are designed to ...

Friend recommendation is popular in social network services to help people make new friends and expand their networks. Friend recommendation is either based on topological structures of a social network, or derived from profile information of users. ...

Multidimensional visualization, which creates visual presentations for datasets of multiple variables, helps users to gain an insight of represented information from different perspectives. This paper presents a multidimensional information ...

In this paper, we introduce an approach to visualize the inference process in a rule engine -- Drools, which employs Rete as its pattern matching algorithm. As a software visualization work, our approach is focused on both static structure of the Rete ...

Recently, pen tilting has been explored in pen-based user interfaces and has shown potential to improve user interaction in various tasks (e.g., menu selection, modeless object manipulation). However, some basic questions concerning pen tilting ...

Establishing and maintaining communication between decision makers, professional responders and general public is vital in many emergency planning and rescue situations. In this paper we present our research on using first-hand information collected by ...

Nowadays, many people are suffering from the disease that their kidneys no longer function adequately. Knowing their own physical conditions accurately and then recognizing the necessity of self-management are the key to the exploration of a better ...

We often want to select tunes based on our purposes or situations. For example, we may want background music for particular spaces. We think interactive evolutionary computing is a good solution to adequately recommend tunes based on users' preferences. ...

An intermediate representation between tabular forms and parallel coordinates is proposed. The new representation makes it possible to switch back and forth between tables and parallel coordinates in smooth transformations. The authors have developed a ...

Large data repositories such as electronic journal databases, document corpora and wikis often organise their content into categories. Librarians, researchers, and interested users who wish to know the content distribution among different categories ...

We present research focused on designing visual analytics (VA) systems for workers in organizational environments. We focus on business analysts and asset managers, who work collaboratively to analyze information and make decisions. Through extensive ...
