Abstract

This paper presents ARCA, a software system that enables semantic search and exploration over a book catalog. The main purpose of this work is twofold: to propose a general paradigm for a semantic enrichment workflow and to evaluate a visual approach to information retrieval based on extracted information and existing knowledge graphs. ARCA has been designed and implemented following a user-centered design approach. Two different releases of the system have incrementally and iteratively developed and evaluated. The first release has evaluated the quality and usefulness of the extracted data. The second release, whose design was a refinement based on the previous evaluation results, was assessed by several users. Moreover, a comparative test with other information retrieval systems was conducted in order to study the potential added-value of the system. ARCA is employed in a real editorial scenario to visually search and explore the books of a publishing house. [ABSTRACT FROM AUTHOR]

Abstract

The article discusses what one might do with a life's worth of digital memories and the applications that might prove useful. It also considers reasons why one might not want to keep everything, outlines research challenges and identifies the leverage that having a complete life record could bring to personal information management problems. It is reported that the primary research challenge in digital memories is how to cope with the vast quantity of material. Summarization, abstraction and data mining approaches can be helpful in identifying important items, though what is important to one person may not be important to another. Use of multiple levels of detail and resolution is desirable for reviewing all captured media, especially sensor data. Another challenge is posed by making use of the increasing number and types of data sources primarily from ubiquitous sensors. It is concluded that however, difficult, technological, legal and social issues must also be solved to make lifetime recording valuable.

4. VidaMine: a visual data mining environment

Abstract

That the already vast and ever-increasing amounts of data still do present formidable challenges to effective and efficient acquisition of knowledge is by no means an exaggeration. The knowledge discovery process entails more than just the application of data mining strategies. There are many other aspects including, but not limited to: planning, data pre-processing, data integration, evaluation and presentation. The human-vision channel is capable of recognizing and understanding data at an instant. Effective visual strategies can be used to tap the outstanding human visual channel in extracting useful information from data. Unlike is the case with most research efforts, the exploitation should be employed not just at the beginning or at the end of the knowledge discovery process but across the entire discovery process. In essence, this calls for the development of an effective user/visual component, the development of an overall framework that can support the entire discovery process/all discovery phases, and the strategic placement of the visual component in that framework. Key issues of this component will be the open architecture, allowing extensions and adaptations to specific mining environments, and the precise semantics and syntax, allowing an optimal integration between the presentation and the computation.
