Information Retrieval and Text Mining direction Another direction in research conducted by the Software Engineering Lab is Cross- Lingual Information Retrieval. New techniques related to Web search technologies applied to Japanese and Chinese were proposed and later tested on data sets provided by the organizers of NTCIR 6 Workshop.

International Relations International Project on Text Mining Last year, we started an international project on Text Mining. Our partner is the Faculty of Applied Mathematics and Control Processes Saint Petersburg State University, Russia. Results of our joint research were presented at The 6th IEEE Conference on Computer and Information Technology (CIT 2006), Korea, September 2006, and at The 9th International Conference on Humans and Computers (HC 2006), September Japan, September 2006. Exchange of undergraduate students Our undergraduate student Mr. Yoshiroh Takanashi visited Saint Petersburg State University, Russia in April 2006 and presented his paper at the XXXVII Conference on Control Processes and Stability. Russian undergraduate student Ms. Elena Smirnova attended the HC 2006 conference in September 2006. This annual conference is organized by our university. This exchange of students was done in accordance with our agreement with Saint Petersburg State University. Coordination Meeting In September 2006, prof. Klyuev visited Saint Petersburg, met members of the Information Retrieval Group, professors and Administration of Faculty of Applied Mathematics Control Processes, Saint Petersburg State University. Key results of these discussions are as follows: Parties discussed the current achievements and agreed to continue cooperation in the field of text mining. Parties agreed that the first year of collaboration was successful: Results of joint research were presented and published in the proceedings of two high rank conferences. Parties defined the priority topics in joint research on text mining and defined the short term perspective. Parties also agreed to exchange 1 or 2 students next year to attend the International XXXVIII Conference on Control Processes and Stability, April 2007, S.Petersburg, Russia and the 10th International Conference on Humans and Computers, Aizu, Japan, December 2007. To implement item 3, Parties agreed to make reasonable efforts to develop, and attempt to provide funding to cover local expenses for students (Russian side for Japanese students and Japanese side for Russian students). Each side will find funds to cover airfare for their students. Our Russian partner proposed to put a report on our meeting on the department Web site. This report in Russian including photos is available at http://top.apmath.spbu.ru/wiki/Aisumeeting1309 These aforementioned activities are supported by the Center for Strategy of International Programs of the University of Aizu. The Software Engineering Lab plays a key pole in these activities.

	Plagiarism detection systems are known for years in the university community. However, most of the existing detectors for the natural language texts use rather simple comparison methods that make the instances of plagiarism easy to hide. The software, designed for plagiarism detection in computer programs, utilizes far more advanced techniques. We propose a method, which adds functionalities similar to tokenization and tree matching, to the natural language texts-oriented detectors. This method requires noticeable work to be applied in practice, but also makes use of the existing software for parsing and word sense disambiguation.

	There are several universities in Japan where English is the official language of instruction. Japanese students are expected to read numerous scientific papers and books in English as well as write reports using their second language. This paper presents different language information technologies that support students in their study. We investigate features of Web technologies and handheld devices. We conducted a survey among first and second year students to analyze how they use technologies to improve their comprehension of teaching materials. From the results, we conclude the following: students have to be trained to ensure that they know the details of the technologies and to apply them in practice.
