Recently, a customer review of travel information website has been a big influence on users in accommodations by the spread of the internet. In our research, as preprocessing of picking out information from the reviews, we propose a method to classify sentences into "Opinion sentences" and "Fact sentences" using SVM. And we confirm effectiveness of "opinion sentences" to estimate values by classification reviews into Positive and Negative using SVM.

As C program compilers do not check the array bounds during compiling, array index out of bounds attacks cause serious security problems. Array bound checking is becoming more and more important, however, original array bound checking, which needs programmers manual working, wastes too much time. In this paper, we propose a strategy to address this issue for C code. In this strategy, we use predicate abstraction in the generated CFG (control flow graph), then the CFG is translated to the SMV model using a translating algorithm. Finally, we use the model checking tool-nuXmv to check the array bound. If the array is out of bound, the nuXmv will give the counter-examples.

As Web applications are more widely used and the browser and operating system becomes more diversiform, cross-browser incompatibility becomes more and more serious which may lead to visual faults or malfunction. The existing tools are difficult to pinpoint incompatibility. We propose a model comparison-based compatibility testing method. CRAWLJAX, an open source crawler tool, is used to build the behavioral model of the Web application under testing. Two models are generated by crawling the application in the reference browser and the target browser respectively, and then they are compared to find and locate incompatibility issues. It reduces the workload of the test and repair. Finally, we use a simple example to illustrate our approach.

Speech recognition technology is spreading with personal digital assistants such as smart phones. However, we are concerned about the decline in the recognition rate at places with multiple voices and considerable noise. Therefore, we have been studying a lip operation that would recognize the content of an utterance by reading from an image. Based on this research, we created a database of utterances by Japanese television announcers and English teachers for utterance training in Japanese and English. Furthermore, applying the technology we developed, we propose a method of utterance training using specific equipment. First, we compared the student's utterance with data in the lip movement database. Second, we evaluated the effectiveness of the utterance training equipment.

Kanban is a method used in agile software development. It is a most important tool as it acts as a central communication hub among the members of an agile development team. In this research, the authors develop a prototype of a Kanban tool. The tool displays each developer's tasks across multiple horizontal rows. Therefore, users can assess the task assignment and workloads of team members in one glance. The board also links up with GitHub and has a feature of real time synchronization among clients for distributed development. An experiment showed that the proposed approach was effective.

In this paper, we introduce a case study of digital textbook-based education in professional school to educate nursing and care. Digital textbook is utilized on digital textbook viewer software installed on the table computer. In professional education, using digital textbook is one of promising field to enhance its quality since the detailed description can be easily understood. Further, instructors can know students' condition of learning viewing recorded log of their learning and users history. The latter half of this paper discusses our challenges of use of digital textbook in actual professional education. In nursing education, digital textbook-based instruction and study is not familiar with instructor and students. However, we achieve a measure of our goal of instruction using digital textbook in nursing school.

The Sentiment analysis targeted customer reviews is an active research field in recent years. Customer reviews contain various topics that closely related to interest of reviewer and situation of utilization. Using this relation, it will be possible to show readers information that fits in interest of them. We collected customer reviews from a tourism information web site, estimate topics in the customer reviews by applying LDA and estimate that customer reviews was whether positive or negative.

We previously proposed a utterance recognition system that uses the tracking and analysis of speakers' lip movements as words and sentences are uttered. Also, we compared the lip movements in the SQLite database with those of utterances produced by students learning the method. We accumulated lips movement history of the utterance learner in the conventional utterance learning system and added a function to manage the change of the lips movement of the learner. In this report, we write development and the result of the system.

Students who are not good programming made media art for workshop for children. It was difficult for them to complete it. So, I developed framework in Processing to support and simplify programming. This framework introduced features to simplify. These features are the one for control movement of images. Consequently, All of the student team was completed the work. Therefore introducing features was useful. But improvement is needed, because introducing own concept caused the confusion at the time of introduction to students. This framework is intended for the student who is weak in programming. So it is necessary to solve this problem. Furthermore there was a request that add the function of the random play when the students are creating. This request was intended to improve the quality of work. Consequently, this framework needed two functions. The first is the function to simplify the programming. The second is the function for the improvement of quality of work.
