Web portals are often created to unite and classify information from different web sources in order to satisfy the needs of particular group of internet/intranet users. The main difficulty arising due to maintenance of such portals is that it requires certain time and labour inputs. The other task to solve is to provide users with adaptive interfaces to recognize their interests and help them find and filter the required information.An innovative approach is proposed represented by a combination of search engine elements and an evolutionary algorithm for the navigational interface of the links panel. The system is implemented as a web-based application.
In distance learning the function of measuring the students' knowledge is carried out by computer based assessment systems. However the development of these systems and distance learning as a whole is obstructed by the fact that a human analyst is still required to analyse the reliability of tests used and results obtained.This study reveals that it is possible by analysing the results of assessments to reveal the qualitative adjectives of the tests. This consequently means that it is possible to implement the self-assessment approach into automated testing systems, which would help teachers to evaluate their tests and assessments results without the help of specialists. This will also provide a platform for further automation and improvement of computer based assessment systems using the same principle.Following the study, a set of tools was developed aimed at conducting a comprehensive analysis of the results of assessments, to discover the foregoing factors and to report the conclusions in an understandable form.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
