Task-Centered Information Management (original) (raw)

Task-centred information management

2007

The goal of DELOS Task 4.8 Task-centered Information Management is to provide the user with a Task-centered Information Management system (TIM), which automates user's most frequent activities, by exploiting the collection of personal documents. In previous work we have explored the issue of managing personal data by enriching them with semantics according to a Personal Ontology, ie a user-tailored description of her domain of interest.

The goal of DELOS Task 4.8 Task-centered Information Management is to provide the user with a Task-centered Information Management system (TIM), which automates user’s most frequent activities, by exploiting the collection of personal documents considered as a Digital Library. In previous work we have explored the issue of managing personal data by enriching them with semantics according to a Personal Ontology, i.e. a user-tailored description of her domain of interest. Moreover, we have proposed a task specification language and a top-down approach to task inference, where the user specifies main aspects of the tasks using forms of declarative scripting. Recently, we have addresses new challenging issues related to TIM personalization and user’s task inference. More precisely, the first main contribution of this paper is the design of a profiling ontology for the user, that can be used to semi-automatically populate the Personal Ontology. The second contribution is the investigatio...

From information to interaction: in pursuit of task-centred information management

2007

Abstract In this paper we describe two automatic inference mechanisms constructed around a personal ontology with the aim of providing human like assistance for form-filling. This is part of the wider vision of DELOS Task 4.8 Task-centered Information Management, which aims to create a more activity or task-focused interaction environment for users, taking their individual library of digital information and turning it into a resource for automated support.

Working through task-centered system design

2004

This chapter presents a how-to tutorial to a version of Lewis and Rieman's Task Centered System Design methodology. Using an example of an interface being developed for a catalog store, we show in detail how a practitioner can identify key tasks, use those tasks to do a rudimentary requirements analysis and how one can evaluate prototype designs through a task-centered walkthrough.

Digital Work Environment (DWE): Using Tasks to Organize Digital Resources

2001

DWE is aimed at providing a one-stop access point to local and remote digital library collections, traditional in-house libraries, and most importantly, to the vast array of information resources that exists in the academic community’s local Intranet. Due to vast amount of information available and the difficulty faced by students and staff in finding the relevant resources, there is a need for a better and logical organization of these resources. DWE uses tasks as a means of directing students and staff to the relevant resources. Tasks generally play an important role in system and user interface design. Identifying the user’s tasks enables the designer to construct user interfaces reflecting the tasks’ properties, including efficient usage patterns, easy-to-use interaction sequences, and powerful assistance features. The resources in DWE are organized according to specific tasks performed by the research students and staff in the division of information studies. The tasks and resources were elicited based on the needs of faculty and students through interviews and focus groups.

The Meaning of an Information-Centric Computer Environment

Proceedings of Intersymp 2001 the 13th International Conference on Systems Research Informatics and Cybernetics Baden Baden Germany, 2001

It is often lamented that we human beings are suffering from an information overload. This is a myth, as shown in Fig.1 there is no information overload. Instead we are suffering from a data overload. The confusion between data and information is not readily apparent and requires further explanation. Unorganized data are voluminous but of very little value. Over the past 15 years, industry and commerce have made significant efforts to rearrange this unorganized data into purposeful data, utilizing various kinds of database management systems. However, even in this organized form, we are still dealing with data and not information.

Organizations for greater efficiency and savings in time and cost usually benefit from information systems. To carry out the activity of this system is a great investment. Therefore, studying the impact of Task Characteristics’ Related Factors on Information Systems’ Use can help organizations achieve a significant contribution to the specified goals. Data collected by researcher-made questionnaire. The research used the data collected from 105 users of Ahvaz Metropolitan Municipality Information System. The results show that there are a positive and significant relationship between Task Compatibility and Intention to Use (r= 0.489), Task Compatibility and Use (r= 0.611), Task Difficulty and Intention to Use (r= 0.517) and Task Difficulty and Use (r= 0.588).
