Abstract

This study aims to identify different styles of personal digital information categorization based on the mindscape of the categorizers. To collect data, a questionnaire, a diary study, and 2 semistructured interviews were conducted with each of 18 participants. Then a content analysis was used to analyze the data. Based on the analysis of the data, this study identified 3 different types of categorizers: (i) rigid categorizers, (ii) fuzzy categorizers, and (iii) flexible categorizers. This study provides a unique way to understand personal information categorization by showing how it reflects the mindscapes of the categorizers. In particular, this study explains why people organize their personal information differently and have different tendencies in developing and maintaining their organizational structures. The findings provide insights on different ways of categorizing personal information and deepen our knowledge of categorization, personal information management, and information behavior. In practice, understanding different types of personal digital information categorization can make contributions to the development of systems, tools, and applications that support effective personal digital information categorization.

Abstract

This study investigated how people comprehend three-dimensional (3D) visualizations and what properties of such visualizations affect comprehension. Participants were asked to draw the face of a 3D visualization after it was cut in half. We videotaped the participants as they drew, erased, verbalized their thoughts, gestured, and moved about a two-dimensional paper presentation of the 3D visualization. The videorecords were analyzed using a grounded theory approach to generate hypotheses related to comprehension difficulties and visualization properties. Our analysis of the results uncovered three properties that made problem solving more difficult for participants. These were: (a) cuts that were at an angle in relation to at least one plane of reference, (b) nonplanar properties of the features contained in the 3D visualizations including curved layers and v-shaped layers, and (c) mixed combinations of layers. In contrast, (a) cutting planes that were perpendicular or parallel to the 3D visualization diagram's planes of reference, (b) internal features that were flat/planar, and (c) homogeneous layers were easier to comprehend. This research has direct implications for the generation and use of 3D information visualizations in that it suggests design features to include and avoid.

Abstract

Purpose The purpose of this paper is to investigate and model the process of organizing personal information in digital form in the context of everyday life. Design/methodology/approach A background survey, a diary study and two interviews were conducted with each of the 18 participants, who are information users in social science academic environments. In particular, the personal information organization process (PIOP) model was developed by tracking and analyzing 143 organization events. Findings The PIOP model consists of six stages: initiation, identification, temporary categorization, examination/comparison, selection/modification/creation and categorization. This model also shows actions, thoughts and decisions involved in the organization process, and 19 factors that impact the process. Originality/value This study introduces a new model that specifically shows the process of organizing personal information. This study advances our understanding of the process and informs the design and development of systems and applications that support personal information management.

Abstract

We investigate facets of online health information that are preferred, easy-to-use and useful in accessing online consumer health information from a user's perspective. In this study, the existing classification structure of 20 top ranked consumer health information websites in South Korea were analyzed, and nine facets that are used in organizing health information in those websites were identified. Based on the identified facets, an online survey, which asked participants' preferences for as well as perceived ease-of-use and usefulness of each facet in accessing online health information, was conducted. The analysis of the survey results showed that among the nine facets, the "diseases & conditions" and "body part" facets were most preferred, and perceived as easy-to-use and useful in accessing online health information. In contrast, "age," "gender," and "alternative medicine" facets were perceived as relatively less preferred, easy-to-use and useful. This research study has direct implications for organization and design of health information websites in that it suggests facets to include and avoid in organizing and providing access points to online health information.
