Abstract: A lot of diverse information exists in the Web. It is important to consider whether one really can trust certain Web content. Especially, Web 2.0 content might have lower quality than other media such as books or news papers, so care should be taken. In this article, we discuss how to approach Web information credibility problems using information technology. We review the concept of the information credibility, and describe several researches related to information credibility. We also present our research of Web information credibility analysis.
Keywords： credibility / quality / trustworthiness / expertise / trust / web information / web 2.0 content

Abstract: How much is information found on the Internet reliable? Are overall media representations trustworthy? Is our virtual surfing secured or safe enough? These tree interrogations related to the level of trust and fear over the Internet use, have wide significance.
Statistical data from surveys (Japanese people's information behavior) carried out under our modest supervision indicate that over the past 10 years, the degree of trust Japanese people place in information accessed via the Internet has jumped, even if the content churned out by newspapers and TV is still perceived as more reliable.
Besides, in a comparative survey we made, even though they are, by far, less vulnerable to the Internet related abuses, Japanese people seem to entertain a higher degree of fear than their counterparts in the other 9 countries targeted. The Japanese society's high exposure to news about Internet related problems and abuses, explains such behavior.
One has to bear in mind, though, that the correlation between such news and the level of fear was not of even proportion among targeted countries.

Abstract: Today's information environment has became more hybrid nature of e-resources and physical resources such as Web and book materials. We have conducted multiple experiments in order to understand user's behavior on hybrid information environment. In the experiments, we have focused on academic libraries as an example of hybrid information environment, have used a series of term paper writing tasks for undergraduate students, and have collected various data including eye-tracking and web action data during a task. In this paper, the author shows several experimental and analytical methodologies as well as their results on problem solving behavior of college students.

Abstract: Since the 1990s, Evidence-based Medicine has become widely accepted in medical research and practice. This idea has brought into Library and Information Science, and it became Evidence-based Librarianship (EBL) or Evidence-based Library and Information Science (EBLIS). This article describes Conflict of interest (COI) in biomedical research as an example of Information Science. COI is important issue concerning research integrity and transparency and, eventually, the lives and well-being of people. Many studies about industry relationships with researchers and their consequence were conducted. We reviewed their and our COI research, and discussed current and future issues of them.

Abstract: In order to exemplify the trustworthiness of records and documents, this paper analyses cases on forged Hitler Diary, forged e-mail sent by former Livedoor President Horie Takafumi, and secret agreement on the reversion of Okinawa. It then reviews the origin and methods of diplomatics. Next, it points out that archival science has addressed these issues from the viewpoint of contemporary and custodian. It mentions that the advent of electronic and digitized records redefine these traditional methodologies, and refers some new methods for ensuring the trustworthiness of them, such as digital signature, time stamping, evaluation of optical discs, and documentation of digitization processes.
Keywords： Hitler Diary / E-mail by Horie Takafumi / Secret Agreement on reversion of Okinawa / diplomatics / archival science / ISO 15489 / digital signature / time stamp / optical disc

Abstract: Abiko et al. are proposing the number of patent case that indicates a technical scope of the patent as a qualitative index with a high correlation.
The case grammar that becomes rationales of this number of case elements is a grammatical theory advocated by the linguist named Charles Fillmore, and the theory that analyzes the sentence assuming that the simple sentence consists of one verb related to a deep case (object, place, tool, starting point, terminal, and time, etc.) that shows substance and these.
The present study aims to propose the method of extracting the patent case number of the claim with software automatically, and to verify the automatic extraction accuracy of the patent case number with this software statistically through an actual analysis of sample.
