Signature extraction for overlap detection in documents
- 2002
-
Ingår i: Australian Computer Science Communications. - 0157-3055. ; 24:1, s. 59-64
-
Tidskriftsartikel (refereegranskat)abstract
- Easy access to the Web has led to increased potential for students cheating on assignments by plagiarising others' work. By the same token, Web-based tools offer the potential for instructors to check submitted assignments for signs of plagiarism. Overlap-detection tools are easy to use and accurate in plagiarism detection, so they can be an excellent deterrent to plagiarism. Documents can overlap for other reasons, too: Old documents are superseded, and authors summarize previous work identically in several papers. Overlap-detection tools can pinpoint interconnections in a corpus of documents and could be used in search engines.We describe a web-accessible text registry based on signature extraction. We extract a small but diagnostic signature from each registered text for permanent storage and comparison against other stored signatures. This comparison allows us to estimate the amount of overlap between pairs of documents, although the total time required is linear in the total size of the documents. We compare our algorithm with several alternatives and present both efficiency and accuracy results.

An enterprise viewpoint of wireless virtual communities and the associated uses of software agents
- 2001
-
Ingår i: Internet commerce and software agents. - Hershey : Idea Group Publishing. - 1930708017 ; , s. 265-288
-
Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- We envision the integration of the concepts of virtual communities, electronic markets, and ubiquitous wireless services into agent-enhanced mobile virtual communities which we call AMV-communities, a set of which form the AMV-community-space. We present concepts for an AMV-community modelled with RM-ODP Enterprise Viewpoint concepts, and outline an architecture of AMV-communities using software agents attached to roles. We also illustrate how we cope with disconnected computing by using agents and meta-policy rules.

Awareness and agility for autonomic distributed systems : platform-independent and publish-subscribe event-based communication for mobile agents
- 2003
-
Ingår i: Proceedings. - Los Alamitos, Calif : IEEE Communications Society. - 0769519938 ; , s. 669-673
-
Konferensbidrag (refereegranskat)abstract
- We propose using the publish-subscribe model to complement proprietary or standard agent communication languages, useful particularly in the case of exchanging and disseminating short communications about events and consequently, reducing complexity of multi-agent messaging. We describe how we implemented the event notification mechanism for mobile agents, and analyse experiments that demonstrate the Elvin-based event notification mechanism for communication between Grasshopper agents and aglets. We also discuss message loss due to agent migration and offer solutions to reliable communication between mobile agents using events.

Towards a mobile enterprise framework
- 2000
-
Ingår i: Proceedings. - Los Alamitos, Calif : IEEE Communications Society. - 0769506283 ; , s. 233-
-
Konferensbidrag (refereegranskat)abstract
- The RM-ODP Enterprise Language comprises concepts, rules and structures for the specification of a community, where a community comprises objects (human, software, or combinations thereof) formed to meet an objective. The Enterprise Language focuses on the purpose, scope and policies of the community, where an enterprise policy is a set of rules with a particular objective related to the community's purpose described as obligations, prohibitions, and permissions. In order to enable adaptations of the enterprise's objectives, structure, policies and roles, we are designing a conceptual architecture with a process-oriented view of roles and policy adaptation mechanisms. Mobile enterprise objects interact with the rest of the community via processes called role-proxies

Meta object approach to database schema integration
- 2000
-
Ingår i: Proceedings. - Los Alamitos, Calif : IEEE Communications Society. - 0769508197 ; , s. 145-154
-
Konferensbidrag (refereegranskat)abstract
- Database schema integration is significant not only in building multidatabase systems but also in data warehousing. Meta data, which define schemas, are normally involved in the surrounding issues. And while many of these issues have been addressed in the past, unresolved issues remain. The authors present an approach that not only uses metadata but also uses meta-meta information to make schema integration more possible. Our solution requires a meta object facility that serves not only as a repository but also as a more feasible means of managing meta data. We also advocate the use of such a facility as part of an object oriented middleware environment that provides an open interface standard and several useful services in distributed object management
