Abstract:Abstract. DSMW is an extension to Semantic Mediawiki (SMW), it allows to create a network of SMW servers that share common semantic wiki pages. DSMW users can create communication channels between servers and use a publish-subscribe approach to manage the change propagation. DSMW synchronizes concurrent updates of shared semantic pages to ensure their consistency. It offers new collaboration modes to semantic wiki users and supports dataflow-oriented processes.
“…The synchronization operations in a decentralized social wiki are sketched in Algorithm 5 and make use of these concepts. See Reference for a formal description of the aforementioned operations in the decentralized social wiki DSMW. …”

“…All incremental modifications are immediately visible to other users. In some cases, users may observe inconsistent states of the wiki, as in a database system without transactional support . Handling disagreements: Even when changes to a page are not made with malicious intent, they can still lead to ‘edit wars’ when different groups of users disagree on the content that is being contributed, and they attempt to cancel or override the other groups' input.A single point of view: There is only one authoritative entry on each topic, because either only one version is ever kept by the system or the latest version is the one that is displayed to the user, and the user typically is not encouraged to compare that latest version with previous ones. This is the case for most wikis, including Wikipedia.…”

“…While large systems such as Wikipedia can manage scalability using a distributed infrastructure, this comes at a massive cost, for storage, bandwidth and system maintenance. To address the different issues outlined earlier, many systems have been proposed, such as Wooki , UniWiki , DistriWiki , DSMW , git‐wiki , Smallest Federated Wiki and P2Pedia . These systems extend the wiki concept to a distributed infrastructure, under the names ‘peer‐to‐peer wiki’, ‘mobile wiki’, ‘offline wiki’, ‘federated wiki’ and others.…”
Distributed wiki' is a generic term covering various systems, including 'peer-to-peer wiki', 'mobile wiki', 'offline wiki', 'federated wiki' and others. Distributed wikis distribute their pages among the sites of autonomous participants to address various motivations, including high availability of data, new collaboration models and different viewpoints of subjects. Although existing systems share some common basic concepts, it is often difficult to understand the specificity of each one, the underlying complexities or the best context in which to use it. In this paper, we define, classify and characterize distributed wikis. We identify three classes of distributed wiki systems, each using a different collaboration model and distribution scheme for its pages: highly available wikis, decentralized social wikis and federated wikis. We classify existing distributed wikis according to these classes. We detail their underlying complexities and social and technical motivations. We also highlight some directions for research and opportunities for new systems with original social and technical motivations.

“…These exchanges can be supported by centralized or distributed architectures. In this paper, we propose to use a distributed architecture, and we use DSMW as a support for this architecture [15,14].…”

In this paper, we study tools for providing assistance to users in distributed spaces. More precisely, we focus on the activity of collaborative construction of knowledge, supported by a network of distributed semantic wikis. Assisting the users in such an activity is made necessary mainly by two factors: the inherent complexity of the tools supporting that activity, and the collaborative nature of the activity, involving many interactions between users. In this paper we focus on the second aspect. For this, we propose to build an assistance tool based on users interaction traces. This tool will provide a contextualized assistance by leveraging the valuable knowledge contained in traces. We discuss the issue of assistance in our context and we show the different types of assistance that we intend to provide through three scenarios. We highlight research questions raised by this preliminary study.
