The main reason is that user queries and web documents may belong to different categories given a taxonomy of information. In this study, we attempt to detangle the ambiguity in web search by using a systematic approach. A weighted graph model is utilised to represent the complicated documents network from web search results. In this model, document topics are explicitly defined from the weighted document graph with an unsupervised learning method. On weighing each topic, both the size of the topic and the intra-topic document importance distribution are considered. In order to achieve web search results diversity, the reranking method proposed in this work leverages on the relevance of the documents to the query and related topics. Evaluation results on synthetic data and realistic web pages show the efficacy of a proposed system.","PeriodicalId":113936,"journal":{"name":"Int. J. Knowl.

More than 80% of the everyday ailments can be handled by the patients themselves. However, when symptoms appear, it is often difficult for them to make the right decision, whether a health professional has to be seen or self care is still safe. This paper's objectives are to describe and design a design for all (DFA) principles based web solution for a system that guides the user through a symptom-orientated process of medical history, taking in order to determine a diagnosis. The specific questions and answers are analysed applying a highly sophisticated medical rules-engine. After the analysis, the online medical system (OLMS) presents arguments to the user, which either indicate, that it is still appropriate to self care, or recommend to see a health professional within a defined timeframe. Moreover, OLMS suggests what would be best to do in the user's specific situation.","PeriodicalId":113936,"journal":{"name":"Int. J. Knowl.

This protocol is designed for gathering information about rescues effectively in a big earthquake. For the longevity of networks, terminals are connected to each other in linear form in our protocol, which makes the communication loads among terminals relatively equal. In order to decrease frequency of packet sending, our protocol introduces virtual terminals, in which two neighbouring terminals activate alternatively. Experimental results show that our protocol needs less packets and that the average life time of terminals is longer than other protocols.","PeriodicalId":113936,"journal":{"name":"Int. J. Knowl.

Historically, research has focused on either finding a single expert for a specific task Expertise Finding (EF), or trying to form a group that satisfies various conditions Group Formation (GF). EF is typically group context agnostic, while GF requires complex models that are difficult to automate. This paper focuses on the union of these two, forming groups of experts. We concentrate in this paper on the expertise aspect of GF, since without the needed expertise, regardless of other factors, the task cannot be accomplished.","PeriodicalId":113936,"journal":{"name":"Int.

Although learners' backgrounds have been greatly changed, programming/algorithm education methods remain unchanged. In a typical method, learners are given the grammar of a programming language, an algorithm and some exercises. In such a method, however, many learners who do not understand the algorithm repeat a trial-and-error process without considering the algorithm. Hence, our system can lets learners externalise their understanding of an algorithm by operating objects in a domain world before they code a program.

The system provides awareness information as feedbacks to runners by using their kinetic feature and communication conditions between sensors at the real-time. In particular 3D-acceleration sensor catches repeats of arm swing. Moreover, sensors transmit such information to the remote server on the web. The remote advisor can observe the condition of runners by way of graphic reports of sensing information on the web and control the trigger of awareness manually. We have designed and implemented our proposal. From the result of a trial use, the system contributes some runners' improvements about the stabilisation of their pace.","PeriodicalId":113936,"journal":{"name":"Int. J. Knowl.

In monologues, since a sentence tends to be long, each sentence is often displayed in multilines on the screen. In the case, it is necessary to insert linefeeds into a text so that the text becomes easy to read. This paper proposes a rule-based technique for inserting linefeeds into a Japanese spoken monologue sentence as an elemental technique to generate the readable captions. Our method inserts linefeeds into a sentence by applying the rules based on morphemes, dependencies and clause boundaries. We established the rules by circumstantially investigating the corpus annotated with linefeeds. An experiment using Japanese monologue corpus has shown the effectiveness of our rules.","PeriodicalId":113936,"journal":{"name":"Int. J. Knowl.
