Even ongoing Covid-19 pandemic—which has forced whole sectors social life, including teaching, exercise, religious celebrations, and academic small talk over wine cheese, into virtual sphere—did not change overall ambivale...

A spatial signal is defined by its evaluations on the whole domain. In this paper, we consider stable reconstruction of real-valued signals with finite rate of innovations (FRI), up to a sign, from their magnitude measurements on the whole domain or their phaseless samples on a discrete subset. FRI signals appear in many engineering applications such as magnetic resonance spectrum, ultra wide-b...

Consistency is an essential aspect of the quality of metadata. Inconsistent metadata records are harmful: given a themed query, the set of retrieved metadata records would contain descriptions of unrelated or irrelevant resources, and would even do not contain some resources considered obvious. This is even worse in when the description of the location is inconsistent. Inconsistent spatial desc...

How an object or event is described depends upon numerous factors that have been identified by prior research in linguistics, pragmatics, and psychology. What this prior research has not established, however, is what consequences the resulting choice of linguistic form has on subsequent comprehension processes. This dissertation begins with the assertion that the quantity of information encoded...

The performance evaluation of Content Based Image Retrieval systems (CBIR), can be considered as a challenging and overriding problem even for human expert users regarding the important numbers CBIR proposed in literature applied to different image databases. automatic measures widely used assess are inspired from general Text (TR) domain such precision recall metrics. This paper proposes new q...

Although ethical guidelines for doing Internet research are available, most prominently those of the Association Researchers ( www.aoir.org ), decision-making on publicly naturally-occurring data remains a major challenge. As researchers might also turn to others inform their decisions, this article reviews recent papers online data. Research involving forums such as Facebook pages, Twitter, Yo...
