Mosses (a section of bryophytes), are considered as an important group of non-flowering plants which a modern computer-assisted database system is not yet prepared for their determination and description key in Iran. Following a software package recently designed under a research project for assessment of moss diversity of Iran by the authors, the present paper is prepared to: I) introducing co...

Semantic Web resources such as DBpedia provide a rich source of structured knowledge about geographical features such as towns, rivers and historical buildings. Retrieval from these resources of all content that is relevant to a particular spatial query of, for example, containment or proximity is not always straightforward because there is considerable inconsistency in the way in which geograp...

environmental monitoring and rest or at ion requires efficient access to large amounts of spatial information. the geographic information system (gis) and remotely sensed data are related to both physical and man-mad e features. in order to handle this task, the environmental scienc es section (ess) created the environmental data atlas (eda) that uses spatial keys to link all data sources to a ...

abstract— due to the daily mass production and the widespread variation of medical x-ray images, it is necessary to classify these for searching and retrieving proposes, especially for content-based medical image retrieval systems. in this paper, a medical x-ray image hierarchical classification structure based on a novel merging and splitting scheme and using shape and texture features is prop...

We suggest that the proximity of a country to other countries is a factor that affects its choice as an MNE location. We introduce the concept of a country’s proximity to the global distribution of knowledge, markets and resources, and frame this concept as a function of both geographic distance and the worldwide spatial distribution of these factors. We test our location model on a dataset com...

A methodology for matching bidimensional entities is presented in this paper. The matching is proposed for both area and point features extracted from geographical databases. The procedure used to obtain homologous entities is achieved in a two-step process: The first matching, polygon to polygon matching (inter-element matching), is obtained by means of a genetic algorithm that allows the clas...

Assigning geographical coordinates to shared content has become a popular activity on the Web, but nevertheless there are still huge amounts of media data without any geographical tags. Our approach enables these media data to be geotagged with the help of recently tagged media and knowledge-based collaborative systems. It includes three different methods–querying collaborative systems, documen...
