Exploring Usability of Mobile Text Messaging Interfaces
Lee, Jee-Yeon ;
Journal of Information Management, volume 35, issue 4, 2004, Pages 1~16
DOI : 10.1633/JIM.2004.35.4.001
In this paper, we outline the user interface problems that the text messaging users face to provide empirical basis for developing better improved mobile text messaging system. Our initial hypothesis was that the majority of the problems that the text messaging users face, namely, 1) difficulty in correctly understanding the intent of the incoming messages and 2) problem with frequently mis-addressing the recipient of the outgoing messages, can be accounted for by the poor usability of the text messaging user interface. Our analysis is based on the text message-based communication diaries, which were recorded for one week by each and every one of 75 college students, and survey taken from the same subjects. The data was collected in 2004. The students listed various difficulties including the limited message length, obscure input method, lack of mean to express emotional content, lack of receipt confirmation, lack of auto save feature when preparing messages to send, and lack of means to permanently save messages. Some of these problems were also identified in the previous studies. However, we were able to gather additional problems that the users face and also elicit potential solutions to remedy the problems. From these findings and analysis, we attempted to provide ways to improve the text messaging user interface.

The movement toward knowledge-based economy has been accelerated, which is based on creation, diffusion and utilization of knowledge and information. In this change, Technomarket knowledge information plays a vital role in establishing R&D strategies, deciding on new investments, introducing new technology, finding new market, making up future business plans, etc. In this study, we intend to build a system for techno-market knowledge information, which enables users to analyze and acquire useful data by themselves and provides techno-market knowledge information immediately on technologies and items to experts. In conclusion, through this system we are able to cope actively with the rapid environmental changes and the increasing uncertainties and contribute to a national technology competence.
Evaluation on the Quality of Electronic Journal Usage Report Service

As the more web contents are available through the internet, relative importance of electronic resources in the library collection has gradually increased. While several measurement criteria are used for the effective collection development, the usage statistics is generally accepted as the key factor to assess the retention and cancellation of electronic resources. In this paper it was examined the roles and problems inherent in the electronic journals usage statistics, and then the quality of electronic journal usage reporting services provided by several publishers were evaluated, following the ICOLC and COUNTER guidelines. To apply the usage statistics of electronic journal on the library collection development, it is necessary that libraries, related association and publishers accomplish more consistent and practical usage statistics components. And it is recommended that publisher and aggregator accommodate the guideline for electronic journal usage report.
A Study on the Establishment of Metadata for Licensed Electronic Resources
Lee, Too-Young ; Kang, Soon-Hee ;
Journal of Information Management, volume 35, issue 4, 2004, Pages 57~80
DOI : 10.1633/JIM.2004.35.4.057
Lately, most of the libraries subscribe electronic resources such as e-journals, under the license contracts for the access and use of these electronic resources. It was found that the management of licensed electronic resources in the library has become one of the major problems due to the lack of proper metadata elements in the existing management system of electronic resources. The purpose of the study is to establish metadata for licensed electronic resources.
A Study on Automatic Text Categorization of Web-Based Query Using Synonymy List
Nam, Young-Joon ; Kim, Gyu-Hwan ;
Journal of Information Management, volume 35, issue 4, 2004, Pages 81~105
DOI : 10.1633/JIM.2004.35.4.081
In this study, the way of the automatic text categorization on web-based query was implemented. X2 methods based on the Supported Vector Machine were used to test the efficiency of text categorization on queries. This test is carried out by the model using the Synonymy List. 713 synonyms were extracted manually from the tested documents. As the result of this test, the precision ratio and the recall ratio were decreased by -0.01% and by 8.53%, respectively whether the synonyms were assigned or not. It also shows that the Value of F1 Measure was increased by 4.58%. The standard deviation between the recall and precision ratio was improve by 18.39%.
