In recent years, there has been considerable research on information extraction and constructing RDF knowledge bases. In general, the goal is to extract all relevant information from a corpus of documents, store it into an ontology, and answer future queries based only on the created knowledge base. Thus, the original documents become dispensable. On the one hand, an ontology is a convenient an...

In this work we use of an optimized homotropic transformation structural element in order to improve the preprocessing stage for handwriting and hand printed document analysis. The homotropic transformation is use to improve the sequential thinning procedure. In that case we produce less coarse skeleton lines with a reduced number of thinning cycles. If the documents are not good enough, an ada...

In our research work, we consider that access to semi-structured documents is carried out by a data-oriented query. With different users and a same query, the returned results are always the same although users’ characteristics (interests, preferences, etc.) may be different. In order to solve this problem and to offer a personalized access to semi-structured documents, our objective is to impr...

Given a document collection, existing systems allow users to locate documents either using search keywords or by navigating through some predefined organization of the collection. Other approaches help the user understand a collection by generating summaries or clusters of the documents at hand. However, often users would like to understand how the documents may be related to each other and acc...

In this paper, we propose a novel, hybrid approach to optimize the query expansion source. The main idea is that, on one hand, we analysis the documents selected by user and use the knowledge of Formal Concept Analysis to construct a user concept lattice; on the other hand, we find some documents which are different from the documents mentioned above and build another concept lattice. Then we c...

We describe two empirical studies of how professionals explain documents to lay clients who have varying levels of knowledge about the domain under discussion. We find that hand gestures, and in particular deictic gestures by the professional at various parts of the document play a major role in explanations of documents with clients in face-to-face settings. We describe a preliminary computati...

In traditional Information Retrieval (IR), users often express their needs using simple keywords, because this is the most simple way to query systems. Queries composed of simple keyword terms are also very used in structured IR (i.e. IR on structured documents like XML documents), since they do not require any knowledge of the documents structure. However, such queries are often not sufficient...

Dewarping of documents captured with hand-held cameras in an uncontrolled environment has triggered a lot of interest in the scientific community over the last few years and many approaches have been proposed. However, there has been no comparative evaluation of different dewarping techniques so far. In an attempt to fill this gap, we have organized a page dewarping contest along with CBDAR 200...

The growing volume of RDF documents and their inter-linking raise a challenge on the storage and transferring of such documents. One solution to this problem is to reduce the size of RDF documents via compression. Existing approaches either apply well-known generic compression technologies but seldom exploit the graph structure of RDF documents. Or, they focus on minimized compact serialisation...

Objective The research compared and contrasted hand-scoring and computerized methods of evaluating the grade level of patient education materials that are distributed at an academic medical center in east Tennessee and sought to determine if these materials adhered to the American Medical Association's (AMA's) recommended reading level of sixth grade. Methods Librarians at an academic medical...
