Abstract: One among the major concerns of managers since the emergence of Information Technology (IT) in organizations in the sixties is to prove that the IT /IS (information system) investments have a positive impact on the organization. Over time, the IS’s evaluation dominated the research in IS field. Several variables of IS measurement, called IS success measurements, like user satisfaction, system use, organizational performance and u ser decisional performance [41 ] were developed and considered as substitute for the effectiveness of IS (IS e ffectiveness is measured against the achievement of objectives according to Hamilton and Chervany [ 25 ]). User satisfaction is the most use d in measuring the success of IS and their impact on the organization. This article focuses on the "user satisfaction". Through the analysis of a set of selected articles from the literature about the evaluation of IS , w e have developed a class model (using UML formalism) about the construct user satisfaction.

Abstract: The proposed work exploits acoustic cues at various levels and incorporates them in the present (Spoken Term Detection) STD frame work. Recently proposed new syllabification method [1] for speech signal is being used for STD . In STD, a query and reference speech signals are provided, these speech signals are syllabified using the new syllabification method and features like Mel - frequency cepstral coefficients (MFCC), posterior grams are extracted. These features are then matc hed using template based match techniques like dynamic time warping (DTW) at syllable level instead of regular frame level. This essentially reduces the unwanted matching done at frame level.
