Open Geospatial Data, capable of enriching OpenStreetMap, is being released by governments around the world at an increasing rate. The OSM import methods have been refined since the massive TIGER-import, moving towards assisted methods such as the with micro-tasking method used by the LA and NY buildings imports. While these imports serve as great case studies of imports, they do not deal with complex datasets, or updates to the data, neither do they deal with partitioning of tasks. We examine how the Norwegian FKB-dataset can be imported to OSM using micro-tasking, and perform a user-test to determine the best partition of these micro-tasking tasks. In this we hope to improve the micro-tasking method to enable efficient and correct imports and updates of Open Governmental Geospatial Data to OSM.

15th International Conference, GDN 2015, Warsaw, Poland, June 22-26, 2015, Proceedings. ; This paper presents a novel task-oriented approach to crowdsource the drafting of a constitution. By considering micro-tasking as a particular form of crowdsourcing, it defines a workflow-based approach based on Onto2Flow, an ontology that models the basic concepts and roles to represent workflow-definitions. The approach is then applied to a prototype platform for constitution-making where human workers are requested to contribute to a set of tasks. The paper concludes by discussing previous approaches to participatory constitution-making and identifying areas for future work.

"Die Arbeit untersucht Wettbewerbsstrukturen, in denen die Teilnehmer eines
Turniers in mehr als einer beobachtbaren Dimension oder Outputgröße miteinander
konkurrieren, und in denen ein Wettbewerber einen Preis gewinnt,
wenn er hinsichtlich einer vorgegebenen Anzahl von Dimensionen besser als
seine Konkurrenten abschneidet. Es zeigt sich dabei, dass ein Turnierveranstalter,
der die Anstrengungen der Turnierteilnehmer maximieren möchte, Turniere
mit einer kleinen Anzahl von Outputdimensionen bevorzugen sollte." (Autorenreferat)

Shareable interfaces, those that can be interacted simultaneously by several users, are a common tool used both in CSCW research and in real world applications. They tend however to lack a capability that has been traditionally relevant to the usefulness of computing systems: multi-tasking. In this paper we explain why a combination of the multi-user features of shareable interfaces and the multi-tasking capabilities of general-purpose computing, could be relevant for building useful systems, and why these features are not present today in most of the current prototypes and systems. We also discuss possible approaches for solving the problems that prevent shareable interfaces to fully support multi-tasking, and we present a novel approach based on a distributed, application-centered, content-based gesture disambiguation. We describe how an already existing framework, GestureAgents, implements this new approach, focusing on expanding the description of the relevant elements related to this problem, and conclude with some example applications and a discussion. ; The research leading to these results has received funding from the European Union Seventh Framework Programme FP7 / 2007–2013 through PHENICX project under grant agreement n° 601166.

What should a consultant have managers do between intervention sessions to help further the process of change? This case study suggests that the concept of organizational tasking can provide one answer to this question. Two kinds of organizational task assignments, drawn from the literature on family therapy, are discussed: prescription task assignments and formula task assignments. Their use in helping to resolve a troubled situation in a transit property is described. Time series data are presented that offer evidence on the possible effectiveness of the use of organizational tasking.

Tasking allocated combat aircraft to strike targets is a complicated and time-consuming process for combat planners. Currently, the process of scheduling missions is a two to four day process. To be able to respond quickly to the changing conditions of the battlefield, the military needs to compress the time that this process requires. Despite efforts to develop computer-based tools to automatically plan missions, combat planners still manually perform most of the tasking and scheduling of aircraft and targets. Unfortunately some of the tools currently available are perceived to be complicated and time consuming to use by the planners. They also generate schedules that often require major manual modifications. This means the combat planners often feel it is easier and faster to schedule the missions manually. With these issues in mind, this research created a prototype-scheduling tool that strikes a balance between ease of use, accurately defining and solving the problem, and generating solutions in an operationally useful amount of time. A combination of concepts from project scheduling, object-oriented programming, heuristics methodology, and genetic algorithms form the basis for the methodology developed in the research. This methodology is then demonstrated in a computer-based tool. While the focus of this research is combat planning, the object-oriented approach developed for project scheduling has applications in both the military and civilian sector. This includes a flexible method for modeling the availability of resources.

AbstractA recent paper by Gaver et al. 6 argued the importance of studying service control problems in which the usual assumptions (i) that tasks will wait indefinitely for service and (ii) that successful service completions can be observed instantaneously are relaxed. Military and other applications were cited. They proposed a model in which arriving tasks are available for service for a period whose duration is unknown to the system's controller. The allocation of a large amount of processing to a task may make more likely its own successful completion but may also result in the loss of many unserved tasks from the system. Gaver et al. 6 called for the design of dynamic policies for the allocation of service which maximizes the rate of successful task completions achieved, or which come close to doing so. This is the theme of the paper. We utilize dynamic programming policy improvement approaches to design heuristic dynamic policies for service allocation which may be easily computed. In all cases studied, these policies achieve throughputs close to optimal. © 2008 Wiley Periodicals, Inc. Naval Research Logistics, 2008
