The fields of biomedical researches included biology and medicine has resulted in a sheer amount of published reports, and papers. Above all biomedical text mining has emerged as a vital research domain that has an impact in the project development of these research areas. Therefore, we describe not only the important basic tasks of process of biomedical text mining but also our research experienc... View full abstract»

Context: Cross-project defect prediction (CPDP)research has been popular. One of the techniques for CPDP isa relevancy filter which utilizes clustering algorithms to selecta useful subset of the cross-project data. Their performanceheavily relies on the quality of clustering, and using an advancedclustering algorithm instead of simple ones used in the past studiescan contribute to the performance ...

Usability is one of the crucial quality characteristics of Web applications. It depends strongly on users' subjective evaluation as a result of operating an application. Prototypes employing functions for enhancing usability are therefore needed so that users can validate the functions based on their subjectivity at an early stage of software development. Furthermore, the prototypes need to be ref... View full abstract»

In software development, multiple developers compose a team, and perform a development process. To succeed the development, understanding developers' characteristics are needed. However, there is no way to measure the characteristics of the developer by quantitative analysis. Therefore, a project manager often assigns team members based on his/her own sense, considering experience year of them. Th... View full abstract»

Software maintenance is an important activity on the software lifecycle. Software maintenance does not mean only removing faults found after software release. Software needs extensions or modifications of its functions due to changes in a business environment, and software maintenance also indicates them. In this research, we try to establish a benchmark of work efficiency for software maintenance... View full abstract»

Courses to train modeling competence are held in higher educational institutions. These courses focus on the final artifacts submitted by learners for analysis and/or evaluation and do not clarify the intermediate creation process. This study focuses on quality of the final class diagram submitted by learners and trials and errors during the creation process. We tried to verify a hypothesis that l... View full abstract»

Over Design (OD) and Under Design (UD) are two common forms of negative variability construction which should be considered together to avoid both functional incompleteness and unexpected software quality degradation during design time and run time. Elimination of OD and UD demands the correct identification of OD and UD, and remedy actions rely on the precision of identification of them. A challe... View full abstract»

We propose a software tool REMEST to assist education of the basics of requirement management based on requirements engineering body of knowledge (REBOK) developed by IT professionals in Japan. REMEST automatically examines diagrams containing mind map and activity diagram created using Astah* professional and assists the learning process by providing proper advises according to the progress of th...

Pencil puzzles are the puzzles such that people write answers on problems printed on paper. In this paper, we deal with three pencil puzzles, Satogaeri, Hebi and Suraromu. We show that the problems to decide the solvability of these puzzles are NP-complete. Also, in all of these puzzles, we show that there exist the rules without which the puzzles remain NP-complete.

This paper proposes the design of a computer player. For fighting games that has the advantages of both rule-based and online machine learning players. This method combines multiple computer players and switches control of the fighting character among them at regular time intervals. In this way the computer player as a whole tries to act advantageously against the current opponent player. To selec... View full abstract»

This paper explores the attractiveness of Pokemon which is a turn-based Role Playing Game (RPG) and has been very popular for the decades. In this study we focus on Pokemon battle which is the most important component in Pokemon. The game refinement theory is used as a tool to assess the degree of sophistication of Pokemon battle. For this purpose we apply two approaches of game progress modeling ... View full abstract»

We are concerned with a card game called Daihinmin, which is a multi-player imperfect information game. Using Marvin Minsky's "Society of Mind" theory, we attempt to model the workings of the minds of game players. The UEC Computer Daihinmin Championship is held at The University of Electro-Communications every year, to bring together competitive client programs that correspond to players of Daihi...

Probabilistic model checker plays an important role in quantitative verification for required properties of probabilistic behavior model. PRISM is a well-used tool to be used as a probabilistic model checker. It takes PRISM language to describe probabilistic behavior model. But it is difficult for users of variety background to understand the PRISM language quickly. Meanwhile, manually writing is ... View full abstract»

In order to realize a Shogi program that can select natural moves, in this paper, we propose a method for predicting natural moves based on the flow of preceding moves. We extracted the sequence of moves appearing frequently in the game records of professional Shogi players and compared them with the game records of Shogi programs. We proposed a method that considers the flow of preceding moves, r... View full abstract»

Rating systems are widely used to represent the players' strengths or skills in playing major games such as chess, go, and shogi. We present an alternative method for estimating a player's strength by using the moves played. While popular rating systems including Elo rating are based only on the results of games, i.e., wins, losses, and draws, there are substantial demands for evaluating the quali... View full abstract»
