Knowledge management in the network organization
- Trang 299-304 vol.1
Network organizations have become commonplace in industrialized countries, for improving productivity and competitive strength. Their success depends to a large extent on the sharing of knowledge among participating organizations. However, due to the relative independence of component firms, successful knowledge management in network organizations presents significant challenges. In this paper, re......

Expert system creator: A visual tool for expert systems construction
- Trang 217-222 vol.1
Constructing expert systems (such as production rules sets, decision trees or decision tables) is a crucial task in multiple disciplines. They encapsulate the domain knowledge as well as the application's logic. In this paper, a powerful visual tool for developing expert systems is introduced. It comes with a dictionary-based approach for the integration of expert systems into host projects. A pra......

Meeting in the agora: a description logic approach to peer-to-peer e-commerce
- Trang 319-324 vol.1
We propose a logical approach to supply-demand matching in peer-to-peer e-commerce, where demand and supply are both described as concepts to be matched, either completely -full match- or partially -partial match- as it allows for an open-world assumption. Incomplete information can be dealt with, and absence of information can be distinguished from negative information, allowing one to discard of......

A new approach for vertex guarding of planar graphs
- Trang 417-422 vol.1
Vertex guarding is one of many optimisation problems in graph theory with wide area of applications. It is proven to be NP-hard, therefore fast approximative solutions are significant. In the paper, at first, known algorithms are considered, and then a new algorithm working on planar graphs is introduced. The new algorithm is based on the dynamic approach and produces better and faster solutions. ......

Applications classification and QoS requirements
- Trang 517-522 vol.1
The applications and network services are key points that could provide the user the necessary quality of service. It is very hard to definitely divide the applications and the underlying services to uniquely describe the application and the service classes. This paper tries to comprise different classes of applications into a unique classification. Different standpoints and criteria are included ......

Maximum likelihood estimation of noisy Gaussian Markov random fields
- Trang 85-90 vol.1
In this paper we consider the issues involved in signal extraction and parameter estimation of particular spatial and spatio temporal processes observed with additive Gaussian noise. Within spatial statistics, we discuss maximum likelihood estimation of noisy auto-Gaussian models. For large lattices the estimation method can be computationally demanding thus, we present a maximum likelihood estima......

Using inverted files to compress text
- Trang 443-447 vol.1
This is the first report on a new approach to text compression. It consists of representing the text file with compressed inverted file index in conjunction with very compact lexicon, where lexicon includes every word in the text. The index is compressed using standard index compression techniques, and lexicon is compressed with original dictionary compression method that gives better compression ......

Building critical organisational knowledge: a case study
- Trang 293-298 vol.1
As the basis of competition increasingly depends on the quality of knowledge assets of companies, to sustain competitive advantage, companies must develop critical organisational knowledge. In this paper issues related to utilising knowledge within a company are investigated using a case study. Key findings of the study are outlined, and a framework is proposed to assist organisations in building ......

Implementing a customised meta-search interface for user query personalisation
- Trang 79-84 vol.1
Nowadays it is commonly accepted that the web is structured in a chaotic way. Due to the fact that it grows exponentially, it is a difficult task to efficiently locate specific information. This paper presents a User-defined Meta-Search Engine (UMSE), adaptable to user preferences. UMSE utilises tip to 9 known search engines according to a user-defined ranking, submits its queries in parallel and ......
