As information resources on the web continue to grow tremendously, it becomes progressively more difficult to meet high expectations of users and find relevant information. Although existing search engine technologies can find valuable information, however, they suffer from the problems of information overload and information mismatch. This paper presents a hybrid Web Information Retrieval approach allowing personalised search using ontology, user profile and collaborative filtering. This approach finds the context of user query with least user’s involvement, using ontology. Simultaneously, this approach uses time-based automatic user profile updating with user’s changing behaviour. Subsequently, this approach uses recommendations from similar users using collaborative filtering technique. The proposed method is evaluated with the FIRE 2010 dataset and manually generated dataset. Empirical analysis reveals that Precision, Recall and F-Score of most of the queries for many users are improved with proposed method.","PeriodicalId":113936,"journal":{"name":"Int. J. Knowl.

However, evaluating an adaptive system is a difficult task due to the complexity of such systems. Evaluators need to ensure correct evaluation methods and measurement metrics are used. This paper reviews a variety of evaluation techniques applied in adaptive and user-adaptive systems. More specifically, it focuses on the user-centred evaluation of adaptive systems such as personalised recommender systems and adaptive information retrieval systems. The review tackles the question of \"i¾˜How have user-centred evaluations of adaptive and user-adaptive systems been conducted and how can these evaluation practices be improved?' Based on the analysed results of the: (a) evaluation approaches, (b) user-centred evaluation techniques, and (c) evaluation metrics, we propose an evaluation framework for end-user experience in evaluating adaptive systems (EFEx).","PeriodicalId":113936,"journal":{"name":"Int.

But, most existing approaches to social behaviour analysis are static and fall short of considering the varieties and differences in cultures and localities. We propose a dynamic approach to extract localised users' favourite websites through logging the URLs that were accessed by users in places such as universities and government institutions; then by categorising the content of logged websites, our categorised users' favourite websites were created dynamically. We evaluated our approach in a real setting by dynamically building up a database of users' favourite websites in a six months period operating in the ICT Ministry of Iran. Comparison with famous static URL databases showed the superiority of our approach in catching newly published websites, making our approach more durable in performance.","PeriodicalId":113936,"journal":{"name":"Int.

Considering the organisation challenge the students face in CSCL, there is a need for developing computer supported tools to support the students' organisation activity. In this study, we consider the personalised information retrieval in a CSCL task through the use of a Group-Awareness widget (GAw), called EuroCAT. The GAw EuroCAT supports the students' declaration of personal information and their display to the teammates. We aim to analyse the comparative use of the collaboration tools available for the students in the CSCL task comparing the use of GAw EuroCAT allowing to retrieve personalised information and traditional communication tools such as the forum and the chat. A quasi-experimental situation was conducted on psychology undergraduate students. The results showed a higher organisational and knowledge convergence in the group of students using EuroCAT.","PeriodicalId":113936,"journal":{"name":"Int. J. Knowl.

As a consequence Software Engineers spend a significant proportion of time (20\"i¾“30%) searching for information and engaging in opportunistic programming practices, reusing the existing software elements. In this paper, we summarise the findings, discussing how software developers interact with information and information retrieval systems. Importantly we investigate to what extent a domain-specific search and recommendation system can be delivered in order to support their daily activities. Based on two user studies, a questionnaire and an automated observation of user interactions with the browser, we identify that software engineers engage in a finite number of work-related tasks and also develop a finite number of \"i¾˜work practices'/\"i¾˜archetypes of behaviour'. Secondly we identify a group of domain-specific behaviours that can successfully be used for relevance feedback of a domain-specific and semi-collaborative information recommendation system that can support software engineers in performing their daily work-related tasks more effectively.","PeriodicalId":113936,"journal":{"name":"Int.

We made a statistical analysis based on our test. We determined the most frequently occurring errors based on these statistics. We took into account these typical errors, when we determined our minimal guidelines in ten points.
