It is realised that user's search for information on the web using information scent of the clicked URLs is analogous to that of ants searching for food using the pheromone in ACO. The user clicks to the personalised search results is used to update increase/decrease the information scent of the corresponding clicked URLs of the stored query sessions and the associated clusters dynamically. This regular updation of information scent optimises the relevant set of clicked URLs associated with the clusters and hence personalises the user's search effectively. An experimental study was conducted on the web user query sessions to test the effectiveness of the proposed approach and results shows the effective improvement in the precision of search results.","PeriodicalId":113936,"journal":{"name":"Int.

Our aim is to clarify the characteristics, problems in the scientific communication related to the health effects of radiation. The eight books are compared from the aspects of: 1 how units such as Bq, Gy and Sv are defined; 2 how the dose limits are explained; 3 how deterministic and stochastic effects of radiation are differentiated; 4 how LNT model is explained and evaluated; 5 how the fact that we evolved in the midst of natural background radiation is treated. The main finding of our survey is that although the authors of the examined texts start from the same 'scientific facts', in trying to make these facts easily understandable, they adopt different rhetorical strategies and eventually they end up delivering quite different and conflicting messages to the people.","PeriodicalId":113936,"journal":{"name":"Int.

To do so efficiently, after following a hyperlink, a user must be able to rapidly determine whether the desired information is contained on the destination web page. In this paper, therefore, we propose a method called hyperlink referring block estimation HERB, which infers the existence and location of relevant contents on destination web pages. HERB utilises user context in web browsing, in particular, the selected hyperlink and the text around it. Through experiments simulating ordinary web browsing, we quantitatively investigate the effectiveness of HERB. Our experiments show that HERB can infer blocks relevant to a hyperlink with approximately 65% precision and 70% recall. Furthermore, we design two HERB implementations, namely, a web proxy and a web browser, and we present an overview of a web proxy prototype and an example use case.","PeriodicalId":113936,"journal":{"name":"Int.

To overcome these difficulties, this paper applies a revised version of regular polygon-based search algorithm RPSA to approximately search aggregate range query results over remote spatial databases. The algorithm requests a series of k-NN queries to obtain aggregate range query results. The query point of a subsequent k-NN query is chosen from among the vertices of a regular polygon inscribed in a previously searched circle. Experimental results show that precision is over 0.97 with regard to sum range query results and NOR is at most 4.3. On the other hand, precision is over 0.87 with regard to maximum range query results and NOR is at most 4.9.","PeriodicalId":113936,"journal":{"name":"Int. J. Knowl.

Learners use a system to perform a learning task in the domain of history. They have to build a concept map containing a chronology using the system. To be able to support, we combined multiple semantic information sources and Wikipedia, for the natural language information, to create a semantic open learning space. The system provides advice by generating questions based on the semantic information and enhancing document based on the Wikipedia corresponding to the semantic information. All the advices are provided on demand and are generated depending on the learner's concept map for adaptive support question generation.

The navigational maps let evacuees know the current situations of disaster areas: namely, which roads can be used for evacuation, which paths is the shortest to shelters, and so on. In this system, in order to acquire up-to-minute information on road condition in the area, evacuees with mobile devices record roads chosen for evacuation to the shelter as data collection agents. Furthermore, in order to take recentness of information into account, collected road information is restructured into a navigational map based on a mechanism of ant colony systems. By this method, more recently used roads are treated as safer roads for evacuation. In the simulation experiments, we can observe that the proposed map construction system can follow changing situation and provide an up-to-minute safe-road map to a shelter in a disaster area. In addition, we can also clarify that navigational maps provided by our system can reduce evacuation time to shelters in disaster areas.","PeriodicalId":113936,"journal":{"name":"Int. J. Knowl.

Our research objective is to develop a system which automatically generates multiple-choice cloze exercises from input text according to the student's understanding. Our target is supporting individual study of learning English grammar.

Emma shows maps of different scales on the same display region, so that users can use wide maps Context and confirm details Focuses simultaneously. However, when multiple Focuses overlap, Emma is problematic in that road-network connections cannot be correctly drawn. In this paper, we propose the Water Drop method as a solution to this problem. It prevents overlapping by transforming Focuses much in the same way that drops of water are transformed, united, and divided due to surface tension. In order to prove the efficiency of the proposed method, we also developed the Overlap Repulsion method as a baseline approach. It prevents overlapping by moving the inactive Focuses away from the active Focus when an active Focus overlaps inactive Focuses. We conducted three experimental evaluations from the point of view of the both usability of the interface and map visibility.","PeriodicalId":113936,"journal":{"name":"Int. J. Knowl.
