Despite the explosive growth of internet usage, satisfying users' experience in web search while understanding the dynamic nature of search engine ranking remains a challenge. 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.

Health literacy is the basic pre-requisite for a well and healthy life. 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.

In this paper, we propose an ad-hoc unicursal protocol for communication systems in disaster situations. 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.

Research-oriented tasks continue to become more complex, requiring more collaboration between experts. 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.

Recently, non-engineers are becoming to learn algorithms and programs. 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. In this paper, we describe the architecture of our system, and the result of our evaluation.

This paper describes a training-support environment for runners who run together with mobile sensor network. 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.

The development of a captioning system that supports the real-time understanding of monologue speech such as lectures and commentaries is required. 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.

One of today's hottest topics in the field of education is the effectiveness of Learning Management Systems have introduced text chat, bulletin boards into the classroom. However, these systems do not provide visual explanation, by drawing diagrams or numbers on the presentation slides. We developed a classroom lecture system that encourages teacher-to-student and student-to-student communication by means of sharing slides drawn notes using a digital pen. The teacher and students can confirm the explanation by sharing these slides. As a result, enhanced understanding is achieved through classroom questions and answers using both text and visual explanation.

In this paper, we propose a product retrieval method using product reviews. The method calculates the score of a product based on the similarity between a user's request extracted from a natural language query and consumers' opinions extracted from reviews of the product. We also propose the method to generate the thesaurus automatically from consumers' reviews. The thesaurus expresses semantic similarities between opinion expressions. We implemented an accommodation retrieval system and constructed the opinion thesaurus automatically from 652,875 reviews. The experimental results show the effectiveness of our method.

We have developed a system called LiNeS to facilitate exercises with virtual machines in the existing computer laboratories of universities. We achieved this by establishing a method for constructing a virtual network consisting of heterogeneous virtual machines, and another method for constructing overlay networks consisting of virtual networks on each PC; in addition, we developed several functions for supporting exercises. In this study, we evaluated LiNeS in experiments that students performed with actual machines and with LiNeS, with the help and supervision of assistants.
