Steganography is a science of hiding messages into multimedia documents. A message can be hidden in a document only if the content of a document has high redundancy. Although the embedded message changes the characteristics and nature of the document, it is required that these changes are difficult to be identified by an unsuspecting user. On the other hand, steganalysis develops theories, meth...

COMPOSING SYSTEMIC ASPECTS INTO COMPONENT-ORIENTED DOC MIDDLEWARE

The arXiv is the most popular preprint repository in the world. Since its inception in 1991, the arXiv has allowed researchers to freely share publication-ready articles prior to formal peer review. The growth and the popularity of the arXiv emerged as a result of new technologies that made document creation and dissemination easy, and cultural practices where collaboration and data sharing wer...

Purpose – Many companies still use paper documents within their service processes, which is supposed to be inefficient, and a digitalisation of documents is a promising alternative. However, such a change is expensive and the process typically has to be adapted. Thus, the purpose of this paper is to show how business process simulation (BPS) can be used to forecast the effects of the introducti...

AIM The name of a disease entered in medical documents often differs from the true diagnosis in psychiatric practice. We examined the effects of different translations of 'schizophrenia' into Japanese on the usage of disease names in documents. METHODS We conducted a retrospective survey of the names of diseases used in the medical documents of 250 outpatients with schizophrenia or depression...

IN THE CLINICAL SETTING we want to enhance the learning of students, junior doctors and trainees to help them be better doctors, but not increase the time we spend making that happen. Junior doctors are adults who want to learn. If we feel that learning is not progressing as it should, we need to consider whether the style in which we teach and the style in which junior doctors like to learn ar...

The goal of this dissertation is to develop methods for supporting and enhancing intellectual activities. For this purpose, firstly, we propose a method for retrieving relevant documents. Secondly, we propose a summarization method for multiple articles. Thirdly, we investigate a method of acquiring case frames from monolingual corpora. And, we present a word-sense disambiguation method require...

Given the enormous amounts of information available only in unstructured or semi-structured textual documents, tools for information extraction (IE) have become enormously important. IE tools identify the relevant information in such documents and convert it into a structured format such as a database or an XML document. While first IE algorithms were hand-crafted sets of rules, researchers soo...

One of the main purposes of textual documents collation is to identify a base text or closest witness to the base text, by analyzing and interpreting differences also known as types of changes that might exist between those documents. Based on this fact, it is reasonable to argue that, explicit identification of types of changes such as deletions, additions, transpositions, and mutations should...
