This paper presents a fusion approach to sentiment detection that combines multiple sources of evidence to retrieve blogs that contain opinions on a specific topic. Our approach to finding opinionated blogs on topic consists of first applying traditional information retrieval methods to retrieve blogs on a given topic and then boosting the ranks of opinionated blogs based on the opinion scores computed by multiple sentiment detection methods. Our sentiment detection strategy, whose central idea is to rely on a variety of complementary evidences rather than trying to optimize the utilization of a single source of evidence, includes High Frequency module, which identifies opinions based on the frequency of opinion terms (i.e., terms that occur frequently in opinionated documents), Low Frequency module, which makes use of uncommon/rare terms (e.g., "sooo good") that express strong sentiments, IU Module, which leverages n-grams with IU (I and you) anchor terms (e.g., I believe, You will love), Wilson's lexicon module, which uses a collection-independent opinion lexicon constructed from Wilson's subjectivity terms, and Opinion Acronym module, which utilizes a small set of opinion acronyms (e.g., imho). The results of our study show that combining multiple sources of opinion evidence is an effective method for improving opinion detection performance.

Recently, with the implementation of the "e-Government Performance Management Guidelines," there is a growing demand for setting performance indicators for information systems. For systems that provide information services to the public, such as CODIL, it is not easy to set performance indicators. This study presented a research model that applies Monte Carlo simulation to set expected performance targets that can be achieved through CODIL based on objective evidence. Among the survey contents conducted from 2015 to 2023, the statistical characteristics of user satisfaction regarding the frequency of use of construction technology information provided by CODIL were designated as input variables. Future expected targets and confidence intervals from 2024 to 2026 were designated as outcome variables. The expected target value was measured by generating 5 simulation alternatives and 1,000 random numbers for each alternative. Next, the measured expected goals were interpreted and compared with the results of time series regression analysis measured in previous studies. Although, as in previous studies, the expected target value could not be predicted based on time series regression analysis that considers the correlation between years. However, compared to previous studies, this study can be considered a more accurate analysis result because it predicted the expected target value based on 5,000 input variables.

This study has introduced folksonomy to general patterns of folksonomy tags for the university libraries that have practically implemented Library 2.0. From the results, we can see that average about 1.35 tag is used for one content. Typical pattern of the tags follow a power function that frequency of use decreases as No. of uses increases, 79.51% of tags are expressing topic of contents, and 84.61% of tags are tag of social motivation. The results of analysis on increase/decrease rate for tags divided into 4 quarters said that A university library has big differences from quarters while B university library has similar data between quarters. The users have used average 5.25 tags. Trends of the users can be divided into 3 groups according to tagging patterns of the users.

The major users of children's library are children and housewives. Recent increasing frequency of their visit to the library expands the function of it from the place where they borrow and read books further to the cultural space where each family unit can enjoy leisure activities. Though the children's library basically is a quiet place for reading books, peers' establishing friendship and emotional bond with the parents, and such plays as small scale muscular movements take place in addition to reading activities because the major users are infants under six or children in the lower grades in elementary school. Thus, in order to study the features and requirements that are inherent in the various behaviors of the children who use furniture, understanding of the particular factors in the physical environment of the children's library and the user context must precede. In reality, though the fixed form of the desks and chairs in the library was made by a small number of designers, a large number of children are using them in tremendously various ways beyond the ways that the designers had intended, adapting themselves to the environmental context. Therefore, the purpose of this study is to find out the children's using way of seats when they do reading and playing activities based on the way of interaction between children and parents, and, after modeling of the children's behavior data, to understand the demands inherent inside the various behaviors of children who use furniture.

In this study, the characteristics and types of 1D, 2D barcodes were examined. It is necessary to provide mobile services by making full use of the advantages of the technologies, such as 1D, 2D barcodes, and RFID, and by complementing the disadvantages of them mutually in Korea. Especially, in a mobile environment where the spread of smart phones and mobile networks are expanding, barcodes and RFID (Radio-Frequency Identification) were analyzed as a very useful information media which is able to connect offline analogue media and online digital media. In addition, library automation systems and the cases of mobile student ID services using barcodes and RFID in Korean libraries were analyzed. The cases of mobile services using barcodes in foreign countries were also analyzed. With these cases, we propose a method to empower mobile services using barcodes in Korean libraries.
