The main obstacle to realize real semantic-based image retrieval is that semantic description of versatile images is difficult. The basic ideas of this paper are that the semantics of an object can be refined through top–down orthogonal semantic classification and that the semantics of an object can be reflected by the semantics of relevant objects and the semantic relationships between them. T...

The aim of this study is to investigate the relationships between citations and the scientific argumentation found in the abstract. We extracted citation lists from a set of 3200 full-text papers originating from a narrow domain. In parallel, we recovered the corresponding MEDLINE records for analysis of the argumentative moves. Our argumentative model is founded on four classes: PURPOSE, METHO...

The scientific community is sensitive to concerns about how and why animals are used in biomedical research and testing. Although alternatives to methods based on the use of animals may not satisfy all the requirements of the biomedical research communities, alternatives to the use of vertebrates have been developed and validated. Research on such methodologies is aimed at refining procedures t...

This paper investigates the use of the logical structure in XML documents for the retrieval of XML multimedia objects. We study different logical levels and their combinations. Our investigation is carried on a purposebuilt test collection based on the INEX test collection. Our findings are the followings. First, all logical levels allow discriminating between elements contained in different do...

BACKGROUND Cancer is a disease characterized as an uncontrolled growth of abnormal cells that invades neighboring tissues and destroys them. Lung cancer is the primary cause of cancer-related deaths in the world, and it diagnosis is a complex task for specialists and it presents some big challenges as medical image interpretation process, pulmonary nodule detection and classification. In order ...

Advances concerning publication-level classification system have been demonstrated striking results by dealing properly with emergent, complex and interdisciplinary research areas, such as nanotechnology and nanocellulose. However, less attention has been paid to propose a delineation procedure using specific subjects and understand how it could provide interesting regards about it. This study ...

1 We discuss the use of heuristic search in a graph of cases and other domain knowledge to supply support for an argument. We contend that for legal argument, a gap exists between the vocabulary of constraints upon arguments and the indexing vocabulary for cases and other domain resource knowledge. We suggest best-first search of a graph of cases and other domain knowledge as a means to partial...

Two critical stages in case-based design are the retrieval of a suitable design and the adaptation of that design. When a new design problem is presented to the system, the retrieval stage locates a similar design solution that is reusable in the current context. During adaptation, retrieved designs are modified to meet the specific demands of the target problem. In this paper, we address both ...

Both Geographic Information Systems and Information Retrieval have been very active research fields in the last decades. Lately, a new research field called Geographic Information Retrieval has appeared from the intersection of these two fields. The main goal of this field is to define index structures and techniques to efficiently store and retrieve documents using both the text and the geogra...

In this paper we introduce, the ​FlashText​,​1 algorithm for replacing keywords or finding keywords in a given text. FlashText can search or replace keywords in one pass over a document. The time complexity of this algorithm is not dependent on the number of terms being searched or replaced. For a document of size ​N ​(characters) and a dictionary of ​M keywords, the time complexity will be ​O(...
