Abstract [en]

The Semantic Web will enable business-to-business in new ways. In this context, organizations will need to incorporate the Semantic Web into their work routines. However, this should be done in a way that does not require major changes in the organization. To this aim we propose a model for integrating the usage of the Semantic Web into an organization's work routines. The central component of the model is an sButler, a software agent that mediates between the organization and the Semantic Web. Further, we describe an architecture for one of the important parts of the sButler, show its feasibility with an implemented prototype, and discuss a test using a travel scenario.

Abstract [en]

In the sButler project (Semantic Web Butler) at Linköpingsuniversitet, Sweden, we examine the modeling and instantiation ofworkflows based on Web services (services described in a rule-basedlanguage). The aim of the project, which is part of the SwedishSemantic Web initiative, is to support on-the fly creation ofworkflows and their subsequent maintenance. Our sButler agent willmanage workflows and Web services modeled as Petri Nets, use thelanguage facilities provided by the Semantic Web, and employ a newpush-and-pull protocol to handle communication with other sButlers.

Abstract [en]

Electronic mail (e-mail) is an under-utilised resource of information and knowledge. It could be an important part of the larger so-called organisational memory (OM)—if it were not so disorganised and fragmented. The OM contains the knowledge of the organisation’s employees, written records, and data. This thesis is about organising and managing information in, and about, e-mail so as to make it retrievable and usable for task management purposes.

The approach is user-centred and based on a conceptual model for task management. The model is designed to handle tasks that occur in the communications in an open distributed system, such as Internet e-mail. Both structured and unstructured tasks can be supported. Furthermore, the model includes management of desktop source information, which comprises the different electronically available sources in a user’s computer environment. The information from these is used in the model to sort information and thereby handle tasks and related information. Tasks are managed as conversations, that is, exchanges of messages.

We present a language called Formal Language for Conversations (FLC), based on speech act theory, which is used to organise messages and relevant information for tasks. FLC provides the container for task-related information, as well as the context for managing tasks. The use of FLC is exemplified in two scenarios: scheduling a meeting and making conference arrangements. We describe a prototype based on the conceptual model. The prototype explicitly refines and supports the notion of threads, which are employed so as to give tasks a context. It integrates the use of FLC into the traditional threading mechanism of e-mail, in addition to matching on text in the body. An agent architecture is also described, which is used to harmonise the information in the heterogeneous desktop sources. Finally, human-readable filtering rules created by a machine learning algorithm are employed in the prototype. The prototype is evaluated with regard to its thread-matching capability, as well as the creation of usable and readable filtering rules. Both are deemed satisfactory.

Abstract [en]

Managing information in the form of text is the main concern of this thesis. In particular,we investigate text that is daily made available through the increasing use of e-mail. Wedescribe the design and implementation of a conceptual model,CAFE (CategorizationAssistant For E-mail). We also present the results of a case study and a survey that moti-vate the model.

The case study studies the effect of the computer screen on people’s structural build-up ofcategories for e-mail messages. Three different representations of categories are used:desktop, tree, and mind map. Cognitive science theories have served as an inspiration andmotivation for the study. The survey presents a selection of currently available e-mail cli-ents and the state-of-the-art and trends in e-mail management.

Our conceptual model provides support for organization, searching, and retrieval of infor-mation in e-mail. Three working modes are available for satisfying the user’s variousneeds in different situations: the Busy mode for intermittent usage at times of high stress,the Cool mode for continuous usage at the computer, and the Curious mode for sporadicusage when exploring and (re-)organizing messages when more time is at hand.

A prototype implementation has been developed. Each mode required using a different in-formation retrieval and filtering technique. Busy uses the text-based Naive Bayesian ma-chine learning algorithm, Cool uses common e-mail filtering rules, and Curious uses acombination of clustering techniques known asSCATTER/GATHER. Preliminary tests of theprototype have proved to be promising.
