Most cognitive psychology experiments evaluate models of human cognition using a relatively small, well-controlled set of stimuli. This approach stands in contrast to current work in neuroscience, perception, and computer vision, which have begun to focus on using large databases of natural images. We argue that natural images provide a powerful tool for characterizing the statistical environme...

mation repositories to meet this challenge. This metainformation represents the principal domain of the underlying information repositories. The ontologies group database collections that store similar information, and individual databases join and leave the formed ontologies at their discretion. A common global ontology has been proposed to share information sources in large environments. This...
متن کاملEvaluation of PTFs Developed From Large Databases for Iranian Soils To Predict SMRC
The majority of hydraulic processes under a natural condition in a field are carried out under unsaturated flow conditions. The soil moisture retention curve (SMRC) is the most important hydraulic characteristic of an unsaturated soil whose knowledge is of prime importance in soil-water studies such as soil conservation, soil erosion, land evaluation, soil reclamation, and water resources manag...
متن کاملTautomerism in large databases
We have used the Chemical Structure DataBase (CSDB) of the NCI CADD Group, an aggregated collection of over 150 small-molecule databases totaling 103.5 million structure records, to conduct tautomerism analyses on one of the largest currently existing sets of real (i.e. not computer-generated) compounds. This analysis was carried out using calculable chemical structure identifiers developed by ...
متن کاملConstructing Large Proposition Databases
Using semantic parsing or related techniques, it is possible to extract knowledge from text in the form of predicate–argument structures. Such structures are often called propositions. With the advent of massive corpora such as Wikipedia, it has become possible to apply a systematic analysis of a wide range of documents covering a significant part of human knowledge and build large proposition ...
