“A CONTEXT-BASED ACTOR MODELING APPROACH TO SUPPORT HUMAN MULTITASKING AT ORGANIZATIONS”

Abstract:
Organizational Modeling has been used both for Management and Engineering ends. As an engineering tool, Business Process Modeling has been extremely useful in improving the efficiency of organizations. Nevertheless, it does not provide all the answers to the operational problems of the organization. Current business process oriented tools do not work as well for non-structured processes because they assign tasks in a mechanistic, machine-oriented, way. This is an important issue because many business processes are fairly static only at a high level. At lower levels -at the activity or task level- they tend to be more agile. Business process models are also not capable of capturing the multitasking dynamics of people at work. Task-switching implies less time to obtain the information required by tasks and knowledge about when tasks are actually being executed. This entails not only personalized and fast, but also timely information provision mechanisms.
An organization must be viewed from several perspectives or views if it is to be fully described and understood. The goal of the present research is to propose an organizational perspective capable of describing the actual execution of the various business activities, focusing on its actors and on the multitasking capabilities of its performers. The proposed model is to be used for engineering ends. The main expected contributions of this model are: (1) serve as a visualization tool of the state of the different tasks being performed by each actor and the rules that govern actions and interactions among actors within activities, (2) facilitate a task-based support of ad-hoc environments created by agile process execution and (3) provide a bottom-up approach for the reification of business concepts such as actors, tasks, and organizational units, to establish links with other organizational views and enable ‘consistency checks’ between actual execution and these other views.

Upcoming Events
Research data repositories and tools for human genomics data sharing

Inform the human research community of the status and availability of BioData.pt Local EGA and discuss its need and usability challenges.
The European Genome-phenome Archive (EGA) is a repository for all sequence and genotype experiment types, including case-control, population, and family studies. The EGA will serve as a permanent archive that will archive several levels of data, including the raw data (which could, for example, be re-analysed in the future by other algorithms) as well as the genotype calls provided by the submitters.
Responding to national regulations over human data sharing and other constraints, BioData.pt deploys and operates a Local EGA instance and tools that allow data discovery of genomic and phenoclinic data, following the GA4GH standard and international best practices.
This workshop aims at informing the human research community of the status and availability of BioData.pt Local EGA and discuss from several perspectives its need and usability challenges.
Further details and registration are available here.

The 13th Lisbon Machine Learning School | LxMLS 2023

The Lisbon Machine Learning Summer School (LxMLS) takes place yearly at Instituto Superior Técnico (IST). LxMLS 2023 will be a 6-day event (14-20 July, 2023), scheduled to take place as an in-person event.
The school covers a range of machine learning topics, from theory to practice, that are important in solving natural language processing problems arising in different application areas. It is organized jointly by Instituto Superior Técnico (IST), a leading Engineering and Science school in Portugal, the Instituto de Telecomunicações, the Instituto de Engenharia de Sistemas e Computadores, Investigação e Desenvolvimento em Lisboa (INESC-ID), the Lisbon ELLIS Unit for Learning and Intelligent Systems (LUMLIS), Unbabel, Zendesk, and IBM Research.
Check online for information about past editions: LxMLS 2011, LxMLS 2012, LxMLS 2013, LxMLS 2014, LxMLS 2015, LxMLS 2016, LxMLS 2017, LxMLS 2018, LxMLS 2019, LxMLS 2020, LxMLS 2021, LxMLS 2022 (you can also watch the videos of the lectures for 2016, 2017, 2018, and 2020).
31st International Conference on Information Systems Development (ISD 2023)

The 31st International Conference on Information Systems Development (ISD 2023) conference provides a forum for research and developments in the field of information systems. The theme of ISD 2023 is “Information systems development, organizational aspects and societal trends”. New trends in developing information systems emphasize the continuous collaboration between developers and operators in order to optimize the software delivery time. The conference promotes research on methodological and technological issues and how IS developers and operators are transforming organizations and society through information systems.
The ISD 2023 conference held this year also provides an opportunity for researchers and practitioners to promote their research, practical experience, and to discuss issues related to Information Systems through papers, posters, and journal-first paper presentations.
ISD 2023 will be hosted by Instituto Superior Técnico, in Lisbon, Portugal, on August 30–September 1, 2023.
