In this paper we study the predictive ability of some association rule measures typically used to assess descriptive interest. Such measures, namely conviction, lift and χ are compared with confidence, Laplace, mutual information, cosine, Jaccard and φ-coefficient. As prediction models, we use sets of association rules generated as such. Classification is done by selecting the best rule, or by ...

Th is paper investigates the role of information technology in fi nancial reporting as well as the relationship between using information technology and its impact on the quality of fi nancial reporting. To identify the impact of information technology on quality of fi nancial reporting, a questionnaire was designed and developed. In order to test the hypotheses, T-Test, ANOVA and Duncan’s Test...

Brute health information delivery to various devices can be easily achieved these days, making health information instantly available whenever it is needed and nearly anywhere. However, brute health information delivery risks overloading users with unnecessary information that does not answer their actual needs, and might even act as noise, masking any other useful and relevant information deli...

The inverted index is widely used in the existing information retrieval field. In order to support containment queries for structured documents such as XML, it needs to be extended. Previous work suggested an extension in storing the inverted index for XML documents and processing containment queries, and compared two implementation options: using an RDBMS and using an Information Retrieval (IR...

The text surrounding citations within scientific papers may contain terms that usefully describe cited documents and can benefit retrieval. We present a preliminary study that investigates appending citation contexts from citing documents to cited documents in the iSearch test collection. We examine the effect on information retrieval performance of a range of citation context sizes and their v...

We develop in this paper a (semi-) blind channel estimation algorithm for space time (ST) block precoded OFDM transmissions over frequency-selective channels. We establish that multi-channel identifiability is guaranteed up to one or two scalar ambiguities, when distinct or identical precoders are employed for even and odd indexed symbol blocks. With known pilots inserted before precoding, we r...

On the Semantic Web, the types of resources and the semantic relationships between resources are defined in an ontology. By using that information, the accuracy of information retrieval can be improved. In this paper, we present effective ranking and search techniques considering the semantic relationships in an ontology. Our technique retrieves top-k resources which are the most relevant to qu...

The purpose of this note is to give the readers of 4OR information on the state of the journal and its future, abiding by a triennial tradition which started with Bouyssou et al. (4OR 1(1):1–6, 2003) and continued with Bouyssou et al. (4OR 4(1):1–9, 2006) and Bouyssou et al. (4OR Q J Oper Res 7(1):15, 2009). In the 3years that have passed since the last editorial note, three volumes of the jour...
