An organic electroluminescent element has at least one pair of electrodes including an anode and a cathode and one or more organic functional layers between the anode and the cathode that are in a pair. The organic electroluminescent element includes an organic functional layer that exists as a continuous phase over an entire display area and includes an at least one light emitting compound with a concentration gradient in an in-plane direction and in a thickness direction of the organic functional layer.

An inter-word score calculation apparatus calculates a degree of relatedness between words included in an amount of data from at least one document. The inter-word score calculation apparatus includes a memory storing document data from the documents, term list data wherein predetermined terms are written and a processor. The processor performs a combination process of amplifying an amplification candidate word, which is a word corresponding to a term in the term list data and included in the document data, creating an amplified word, and adding the amplified word to the document data creating processed document data, calculate the degree of relatedness between words included in the processed document data using a predetermined calculation method, and when an amount of documents accumulated in the document data is smaller than a first predetermined amount, add the amplification candidate word to the processed document data.

Provided is a polyhedral transition metal complex including a hollow shell, the hollow shell including n1 (where n1 is an integer from 6 to 60) transition metal atoms and 2(n1) bidentate organic ligands, the bidentate organic ligands including a group derived from a polyhydroxy compound via a linking group, and formed so that the group derived from the polyhydroxy compound is oriented toward an inner space of the hollow shell. Also provided are: an ultrafine particle-containing transition metal complex including the polyhedral transition metal complex, and ultrafine particles of a metal oxide, the ultrafine particles being included within the hollow shell of the polyhedral transition metal complex; a method of producing the same. The invention thus provides a polyhedral transition metal complex that makes it possible to efficiently produce metal oxide particles having a uniform particle size of several nanometers, an ultrafine particle-containing polyhedral transition metal complex in which metal oxide particles are included within a polyhedral structure and the method of producing the same.
