The issue of coordination in Socio-Technical Systems (STS) mostly stems from “humans-in-the-loop”: besides software-software we have software-human interactions to handle, too. Also, a number of peculiarities and related engineering challenges makes a socio-technical gap easy to rise, in the form of a gap between what the computational platform provides, and what the users are expecting to have. In this paper we try to shed some light on the issue of engineer- ing coordination mechanisms and policies in STS. Accordingly, we highlight the main challenges, the opportunities we have to deal with them, and a few selected approaches for specific STS application domains.]]>

The thesis proposes the Molecules of Knowledge (MoK) model for self-organisation of knowledge in knowledge-intensive socio-technical systems. The main contribution is the conception, definition, design, and implementation of the MoK model. The model is based on a chemical metaphor for self-organising coordination, in which coordination laws are interpreted as artificial chemical reactions ruling evolution of the molecules of knowledge living in the system (the information chunks), indirectly coordinating the users working with them. In turn, users may implicitly affect system behaviour with their interactions, according to the cognitive theory of behavioural implicit communication, integrated in MoK. The theory states that any interaction conveys tacit messages that can be suitably interpreted by the coordination model to better support users' workflows. Design and implementation of the MoK model required two other contributions: conception, design, and tuning of the artificial chemical reactions with custom kinetic rates, playing the role of the coordination laws, and development of an infrastructure supporting situated coordination, both in time, space, and w.r.t. the environment, along with a dedicated coordination language.]]>

Distributed systems are more about interaction than computation: thus, they need coordination abstractions and techniques for managing the associated space of interaction. Inspired to the archetypal Linda model, TuCSoN is a coordination model and technology providing tuple-based coordination services to (mobile) software agents through the notion of tuple centre—that is, a programmable tuple space. ReSpecT is a coordination language enabling run-time programmability of TuCSoN tuple centres—that is, of the coordination primitives and laws enabling and constraining interaction.

Molecules of Knowledge (MoK) is a coordination model supporting self-organisation of knowledge in Knowledge Intensive Environments (KIE). Usual approaches to knowledge management in KIE consider data as a passive, "dead" entity and rely on "brute force" approaches assuming an ever-increasing computational power and storage capacity (e.g. big data). This won't scale forever, thus alternative approaches should be explored. MoK promotes the vision of data as a "live" thing, continuously and spontaneously interacting and evolving---self-organising. Accordingly, MoK relies on features such as locality, probability and situatedness to tackle KIE challenges such as scale, openness and unpredictability. In this seminar, the MoK model is motivated and introduced, then some early "evaluation" described.]]>

The “local-to-global” issue in self-organisation is about finding a way to engineer local mechanisms according to the emergent, global behaviour desired for the system at hand. In this paper, we propose an approach to deal with such issue, by modelling the local mechanisms as artificial chemical reactions and by carefully designing their kinetic rates as “custom” functional expressions.]]>

Molecules of Knowledge (MoK) is a coordination model supporting self-organisation of knowledge in Knowledge Intensive Environments (KIE). Usual approaches to knowledge management in KIE consider data as a passive, "dead" entity and rely on "brute force" approaches assuming an ever-increasing computational power and storage capacity (e.g. big data). This won't scale forever, thus alternative approaches should be explored. MoK promotes the vision of data as a "live" thing, continuously and spontaneously interacting and evolving---self-organising. Accordingly, MoK relies on features such as locality, probability and situatedness to tackle KIE challenges such as scale, openness and unpredictability. In this seminar, the MoK model is motivated and introduced, then some early "evaluation" described.]]>

Situatedness is a fundamental requirement for to- day’s complex software systems—as well as for the computation models and programming languages used to build them. Spatial situatedness, in particular, is an essential feature for coordination models and languages, as they represent the most effective approach to face the critical issues of interaction. Following some seminal works [1], [2], [3], in this paper we try to bring some novel results from the Coordination field into the Spatial Computing perspective, by identifying a minimal set of primitives that could be used to build a virtual machine for a space-aware coordination language, using ReSpecT as our reference example.]]>
