Learning activity plays important role in enhancing one's knowledge and skill. There are many ways to acquire and extract learning activities of students from their learning information; we focus on comments handwritten in their attendance sheets. It is easy for teachers to collect the sheets every class and for students to write their activities as comments. The sheets consequently provide time-series text data related to students; such the data are treasures because the comments and the questionnaire reflect their learning activities directly and indirectly. We propose a method called a PCN method for quantifying the comments into triple showing inferred learning activities student by student. Case studies illustrate the validity of the PCN method.

The first aim of this paper is to make a modeling framework of the interest area of a library patron by utilizing library's circulation records. In other words, to profile a person with his/her interest field. Interest area profiling is not only interesting of itself but also useful for library when it chooses purchasing books, for professors when they give lectures, and for other people. The eventual goal of the study presented in this paper is to develop various data analysis methods that provide with useful tips in assisting people, including library patrons, as they learn. The second aim is to develop some useful analysis tools for such pedagogical purpose, especially for analyzing the library data and lecture data. In this paper we propose a concept of virtual faculty of a member of university, which is defined based on the interest area profile of a patron and a faculty. We also give a comparative study between patron and faculty. Even though the approach and analysis methods presented in this paper are in the primitive stage of the research toward this direction, they have a high potential and are expected to be developed to be matured and be practical in the future. © 2013 IADIS.

In this paper we deal with estimating the ranks of library books in their expertise levels. The estimated ranking score is applicable to library-provided learning assistant service. Due to the advancement of information society, library is expected to change in order to meet the patrons' needs. Helping patrons with learning is a key service for libraries. We put emphasis on the learning material recommendation facility for assisting learning patrons and we put focus on material book's expertise level estimation for recommending the material(s) to be learned to the patrons in this paper. As the very first step toward this direction we propose two candidate measures for expertise level ranking, calculate the books expertise level ranking scores, compare them, and evaluate the potential usefulness of this approach. Even though the precision is not yet very high right now, we are expecting the measure can become more precise in the future research and thus becomes practically applicable to libraries. © 2012 IEEE.

To grasp a student's lesson attitude and learning situation and to give a feed back to each student are educational foundations. Goda et al. proposed the PCN method to estimate a learning situation from a comment freely written by students[6, 7]. The PCN method categorizes comments into three items of P (previous), C(current) and N(next). They pointed out a correlation between the student's final results and the validity of a descriptive content of item C, that is something related to understanding of the lesson and learning attitudes to the lesson. However, a problem left in their work is the badness of performance in prediction for upper grade students. This paper proposes two manners of utilization of PCN scores: the validity level determination for assessment, and for prediction performance of students' final grades. In order to validate the proposed manners of utilization, we conducted two experiments. First, we employed multiple regression analysis to calculate PCN scores that determine the validity level with respect to each viewpoint. Students who wrote comments with a high PCN score are considered as those who describe their learning attitude appropriately. We also applied a machine learning method SVM (support vector machine) to students' comments for predicting their final results in five grades of S, A, B, C and D. Experimental results illustrated that as comments of students get higher PCN scores, the prediction performance of the students' grades becomes higher. © 2013 ACM.

The social role of library to assist patrons learn becomes more important toward the future. As our society is changing rapidly and our lives are getting longer, we will keep wishing to learn while we live. So it becomes hard to catch up with the changes of patrons' needs and requirements to libraries if librarians keep working based on the traditional role model. A recommendable idea is to utilize the objective data libraries can get useful knowledge and tips for services and management. Such knowledge backed by data could be very helpful in capturing the patrons' needs for libraries. In this paper, we focus on data analysis for library's learning assisting feature; especially on patron profiling from circulation records of Kyushu University Library. First, we review the measure for expertise level of a book and a patron, which we call prank. Then we propose two concepts for measuring interest range size and earnestness in learning. We compare faculties in their features by applying these measures. It is expectable that such an approach of library marketing with data analysis will eventually reaches to the level in the future so that the measures and tools developed in this approach will become essential for libraries in order to catch up with the environmental changes of patrons and social needs to them. © 2012 IEEE.

This paper proposes a set of Advanced Sunlight Shield Equipment (ASSE) composed of a flat balloon with an attitude control function. Balloon's surface has a mirror function. When ASSE is deployed in the stratosphere, its surface reflects sunlight to space effectively. The gross area of many sets of ASSE amounts to about 2.6 × 106 square kilometre, and when they are deployed, the global average atmospheric temperature value decreases by about 0.7 degrees centigrade. A total cost of ASSE for the average atmospheric temperature decrease is roughly estimated, and it is 1 to 30 ×10 10 euro/year. Copyright © 2012 Inderscience Enterprises Ltd.

Due to the progress of information and communication technology, our society is changing very quickly. Along with this, people's requirements to information are not only changing vigorously but also have a huge variety in their forms. As a result it becomes more and more difficult for the libraries to provide their patrons with appropriate information services. In this paper, we demonstrate the usefulness of the concept of library marketing through some examples; especially with some analysis methods for seat-usage, or seat-occupation, data in library. We investigate what seats are more preferred than others and try to deduce tips for better seat arrangement, combination of different types of seats, etc. Even though our research is in a very early stage so that we could not infer that good suggestions to better seat arrangements, we believe in its importance and it would propose the best solution in seat design in the future. © 2011 Springer Berlin Heidelberg.

Marketing is an essential tool for customer relation management of companies. Contrastingly, non-profit organizations like libraries have not been considered it very useful. However, due to the progress of the information society, our society becomes too complex to capture the patrons's needs for them in the way they have been using so far. The aim of this paper is to demonstrate the importance and usefulness of marketing by presenting some analysis methods of circulation data of a university library and showing what can get about the patrons' behavior. The analysis methods presented in this paper are not only some statistical ones but also non-statistical ones, such as the one for analyzing patron's borrow-return behavior pattern; in other words patron profile. Even though library marketing is in its very early stage, it has a big potential for aiding library management. We have to accumulate the case studies and establish useful marketing methodologies. © 2011 Springer-Verlag.

These days, many university teachers are concerned about the increasing number of students whose motivation is declining. Some of them fall into a situation that they cannot recover from by themselves, and require assistance, but they hesitate to call for help. In order to recognize such students quickly and give guidance to them in class, we have collected time-series comments in the classroom and analyzed them. In the analysis, we divided the comments into the three time slots: P (Previous), C (Current), and N (Next), and quantify them so that we can infer the learning behaviors between the previous and the current classes. We call this analysis method the PCN method. The PCN method is useful for grasping students' learning status in the class. Some of our case studies illustrate the validity of the PCN method. © 2011 Springer-Verlag.

Along with the development of ICT (Information and Communications Technology) and popularization of mobile devices, the information environment of our society has radically changed. As a result, the library's role model also needs to be changed. It is necessary to develop new information services as of e-library at the same time to enrich the currently providing services. Among the various types of e-library services, the most important ones are those of personalized services reflecting the patron's profile such as his/her interest knowledge fields, knowledge level, preferences, etc. The approach we take as the first step toward this direction is to analyze the loan records of library for extracting the patron's interest area information as a profile, and then we understand what the patrons want. We define the interest area based on the decimal classification (DC) categories and use the ratios of books borrowed in these categories as the patron's interest area profile. In this paper, we investigate the correlations of DC categories, and we redefine the profile of a patron so that to understand his/her profile more exactly. The studies in this direction are considered to be useful in developing better elibrary services. © 2014 IADIS.
