This paper compares information theoretic approaches to building Bayesian belief networks to perform market index prediction. We show that the automatic model building can be done efficiently using the 2 ! criteria rather than mutual information alone. We suggest that when the number of variables are small, and instantiations are small, this criteria is a straightforward way of determining cond...

In this paper, we propose a simple and efficient reversible information-hiding scheme for VQ index tables. One secret bit can be embedded into one index pair if this pair passes the predefined restriction. Even if the index pair does not pass the test, it can still carry one secret bit if an additional indicator (a preserved index value) is attached. The experimental results show that our propo...

This paper presents results from the analysis of user interactions in the GEI (German Education Index) specialised search engine. The main interest of this study is getting insights into the GEI users’ typical search behaviour to identify optimisation potential for the further development of the GEI search engine. Based on a sample of query logfiles, the study has revealed that the users apply ...

Age of information is a new concept that characterizes the freshness of information at end devices. This paper studies the age of information from a scheduling perspective. We consider that a base-station updates many users on stochastic information arrivals over a wireless broadcast network, where only one user can be updated for each time. In this context, we aim at developing a transmission ...

The application of information theory to the measurement of income inequality has yielded an impressive array of measurement techniques known as Generalized Entropy (GE) measures. Special cases of this class of index include Theil’s T and L measures which are considered axiomatically superior to other types of metrics including the popular Gini coefficient. In this paper we show that the parall...

Objectives Health information technology (IT) can assist healthcare providers in ordering medication and adhering to guidelines while improving communication among providers and the quality of care. However, the relationship between health IT and Case Mix Index (CMI) has not been thoroughly investigated; therefore, this study aimed to clarify this relationship. Methods To examine the effect o...

We apply a new bibliometric measure, the h-index (Hirsch, 2005), to the literature of information science. Faculty rankings based on raw citation counts are compared with those based on h-counts. There is a strong positive correlation between the two sets of rankings. We show how the h-index can be used to express the broad impact of a scholar’s research output over time in more nuanced fashion...

In connection with the index code construction and the decoding algorithm for interlinked cycle (IC) structures proposed by Thapa, Ong and Johnson in [1] (”Interlinked Cycles for Index Coding: Generalizing Cycles and Cliques”, IEEE Trans. Inf. Theory, vol. 63, no. 6, Jun. 2017), it is shown in [6] (”Optimal Index Codes For A New Class of Interlinked Cycle Structure”, in IEEE Communication Lette...

This paper explores the effectiveness of index terms more complex than single words in conventional information retrieval systems. Retrieval is performed in two phases. In the first phase, a conventional retrieval method (the Okapi system) is used and in the second phase, complex index terms such as syntactic relations and single words with part of speech information are introduced to rerank th...
