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 ......

On-line learning and eTesting
- Trang 147-152 vol.1
In this paper we introduce an eLearning upgrade to the current system for online computer-based testing, applied at the PMF Institute of Informatics. This upgrade offers a possibility for the students to attend the lectures online during the school year and at the same time possibility to check their knowledge. The system is built on a well structured organization of the testing questions. It is t......

Implementing advanced cleaning and end-user interpretability technologies in Web log mining
- Trang 109-113 vol.1
Two new approaches to Web log mining are presented. Novel advanced cleaning improves Web log mining results. Improved filtering removes pages with no links from other pages. In the data visualisation phase, technical representations of Web pages are replaced by user attractive text interpretations. Experiments with the real world problems showed that the proposed techniques significantly increase ......

Off-line signature verification using geometric features specific to Chinese handwriting
- Trang 229-235 vol.1
This paper is concerned with the off-line signature verification scheme. The distinction in our work is that we have taken more consideration with the Chinese signature structure. And we present four main features for the optimization of the verification of the Chinese signatures, viz, the envelop of the signature, cross-count feature, center of gravity of sub-region and distance between vectors m......
