Semantic discovery and reuse of business process patterns

Patterns currently play an important role in modern information systems (IS) development and their use has mainly been restricted to the design and implementation phases of the development lifecycle. Given the increasing significance of business modelling in IS development, patterns have the potential of providing a viable solution for promoting reusability of recurrent generalized models in the very early stages of development. As a statement of research-in-progress this paper focuses on business process patterns and proposes an initial methodological framework for the discovery and reuse of business process patterns within the IS development lifecycle. The framework borrows ideas from the domain engineering literature and proposes the use of semantics to drive both the discovery of patterns as well as their reuse

Geoscience after IT: Part L. Adjusting the emerging information system to new technology

Coherent development depends on following widely used standards that respect our vast legacy of existing entries in the geoscience record. Middleware ensures that we see a coherent view from our desktops of diverse sources of information. Developments specific to managing the written word, map content, and structured data come together in shared metadata linking topics and information types

Ontology-Based Approach for Application Integration

http://interop-esa05.unige.ch/INTEROP/Proceedings/Doctoral/PerPaper/II-1-Izza.pdfInternational audienceEnterprise Application Integration (EAI) is still facing the crucial semantic integration problem. This latter is not correctly addressed by today's EAI solutions that focus mainly on the technical and syntactical integration. Addressing the semantic integration level will promote EAI by providing it more consistency and robustness. Some efforts are suggested to solve the semantic integration problem, but they are still not mature. This paper deals with semantic problem in EAI and will present an ontology-based approach in order to overcome some issues of the integration problem

Integration via Meaning: Using the Semantic Web to deliver Web Services

Presented at the CRIS2002 Conference in Kassel.-- 9 pages.-- Contains: Conference paper (PDF) + PPT presentation.The major developments of the World Wide Web (WWW) in the last two years have been Web Services and the Semantic Web. The former allows the construction of distributed systems across the WWW by providing a lightweight middleware architecture. The latter provides an infrastructure for accessing resources on the WWW via their relationships with respect to conceptual descriptions. In this paper, I shall review the progress undertaken in each of these two areas. Further, I shall argue that in order for the aims of both the Semantic Web and the Web Services activities to be successful, then the Web Service architecture needs to be augmented by concepts and tools of the Semantic Web. This infrastructure will allow resource discovery, brokering and access to be enabled in a standardised, integrated and interoperable manner. Finally, I survey the CLRC Information Technology R&D programme to show how it is contributing to the development of this future infrastructure

A Study of E-Business/E-Manufacturing Models

Traditional business methods are taking a drastic turn and changing to digitized businesses. Information and communication technology is being integrated into orthodox business practices and giving birth to e-business. E-business in turn, is looking up to e-business models for dynamic integration. The e-business concept was first explored. It was broken down into its smaller entities to make for a clearer and better understanding. Components of an electronic business were identified, and e-commerce was understood to be a subset of e-business. It was established that for a business to be e-business enabled, it required information and communication technology (ICT) to be integrated into its brick and mortar business practice. This showed that the e-business concept was not replacing traditional business practices but improving on it. The e-manufacturing business practice was also researched. This practice was found to be in essence e-business, but in the manufacturing context. It showed that e-manufacturing made for a dynamic integration of the complex manufacturing business practice in real-time. It linked shop floors to top floors, as well as all the other areas of the whole manufacturing supply chain. Adequate relevance was established for designing e-business and e-manufacturing models. This was achieved through rigorous literature review as well as a questionnaire survey. A hypothesis design and test based on the literature review was made to ascertain what models are utilized and in what context. Currently used models in different company sectors were discovered, and their subsequent benefits identified. Also reasons behind the adoption of the different models in the firms investigated were identified. Barriers associated with the e-business practice as well as the implementation of an e-business model were also identified. A measurement system was utilized to ascertain if the investigated models met that stated in the literature (i.e. product innovation, infrastructure and the network of partners, customer relation, and finance). This was adopted from that presented in the literature review. Based on the study, a conclusion was drawn and recommendations suggested.

Adapting Searchy to extract data using evolved wrappers

This is the author’s version of a work that was accepted for publication inExpert Systems with Applications: An International Journal. Changes resulting from the publishing process, such as peer review, editing, corrections, structural formatting, and other quality control mechanisms may not be reflected in this document. Changes may have been made to this work since it was submitted for publication. A definitive version was subsequently published in Expert Systems with Applications: An International Journal, 39, 3 (2012) DOI: 10.1016/j.eswa.2011.08.168Organizations need diverse information systems to deal with the increasing requirements in information storage and processing, yielding the creation of information islands and therefore an intrinsic difficulty to obtain a global view. Being able to provide such an unified view of the -likely heterogeneous-information available in an organization is a goal that provides added-value to the information systems and has been subject of intense research. In this paper we present an extension of a solution named Searchy, an agent-based mediator system specialized in data extraction and Integration. Through the use of a set of wrappers, it integrates information from arbitrary sources and semantically translates them according to a mediated scheme. Searchy is actually a domain-independent wrapper container that ease wrapper development, providing, for example, semantic mapping. The extension of Searchy proposed in this paper introduces an evolutionary wrapper that is able to evolve wrappers using regular expressions. To achieve this, a Genetic Algorithm (GA) is used to learn a regex able to extract a set of positive samples while rejects a set of negative samples.The authors gratefully acknowledge Mart´ın Knoblauch for his useful suggestions and valuable comments.

PlanetOnto: from news publishing to integrated knowledge management support

Given a scenario in which members of an academic community collaboratively construct and share an archive of news items, several knowledge management challenges arise. The authors' integrated suite of tools, called PlanetOnto, supports a speedy but high quality publishing process, allows ontology-driven document formalization and augments standard browsing and search facilities with deductive knowledge retrieva

A Network and Repository for Online Laboratory based on Ontology

Our propose is to build a network of virtual laboratories and also use it as a global repository of online laboratory’s and experiences. This set of virtual and online laboratories can be “stored” in an “virtual closet”, and also the system will allow us to build new experiences and online laboratories, and store them is this “virtual closet”. With the drawing of this new standard we pretend define methods for storing and retrieving learning objects for remote laboratories. The objective of this standard is also define methods for linking learning objects to design and implement smart learning environments for remote online laboratories. The objects defined by this standard are, for example, interfaces for devices connected to user computers over computers networks and the devices themselves. They are also learning scenarios or collaboration tools for communications necessary to conduct an activity of practical online laboratory work, they will allow to design and implement mechanisms that make smart learning environment formed by the ad hoc aggregation of learning objects taking always into account the pedagogical context for their use. This will allow to easy design and implement the pedagogically driven remote laboratory environment and experiments as also is learning environments. The experiences and laboratories are build using the parts and separate components that we have in a separate “virtual closet” with parts, components, and already build experiences. To build this complex network we need to find a system that supports effectively this structure. This probably will be a enormous database of v-labs and independent elements, where will be possible sometimes to “recycle” some of the elements. For this structure we propose an Ontology because it allows to “re-use” the same element several times in many experiences, and provide a very detailed description of each kind of element through is classes and sub-classes.Com o apoio RAADRI
