the study is based on 1808 citations appended to 101 research articles published in 7 volumes of 14 issues appeared in the international journal of information science and management (ijism) during 2003 to 2009. earlier, this journal was known (before 2008) as the iranian journal of information science and technology (ijist). here, the author is considering the latest title (ijism) for the stud...

The use of a PDA with ad-hoc built-in information retrieval functionalities can help people in visiting an historical site in a natural manner instead of traditional audio/visual pre-recorded guides. The aim of this work is to build a versatile virtual-guide system adaptable to the user needs of mobility and therefore usable on different devices (e.g. PDAs, Smartphones). An information retrieva...

The purpose of this paper is to investigate acoustic characteristics which distinguish ejectives from pulmonic stops in Ingush (a Northeast Caucasian language), and to compare Ingush ejectives to those of other languages. The articulation of ejectives is relatively well understood, but their acoustic effects are less clear. Working with a native speaker of Ingush, ejectives and pulmonic voicele...

We present a perceptually designed hardwareaccelerated algorithm for generating unique background textures for distinguishing documents. To be recognizable, the texture should produce a random feature vector in the brain after visual feature extraction. Our motivating example is a hypertext user interface which shows a fragment of a link’s target in the margin. Upon traversing the link, the fra...
