STAIR Captions: Constructing a Large-Scale Japanese Image Caption Dataset

In recent years, automatic generation of image descriptions (captions), that is, image captioning, has attracted a great deal of attention. In this paper, we particularly consider generating Japanese captions for images. Since most available caption datasets have been constructed for English language, there are few datasets for Japanese. To tackle this problem, we construct a large-scale Japanese image caption dataset based on images from MS-COCO, which is called STAIR Captions. STAIR Captions consists of 820,310 Japanese captions for 164,062 images. In the experiment, we show that a neural network trained using STAIR Captions can generate more natural and better Japanese captions, compared to those generated using English-Japanese machine translation after generating English captions.Comment: Accepted as ACL2017 short paper. 5 page

PRIME: A System for Multi-lingual Patent Retrieval

Given the growing number of patents filed in multiple countries, users are interested in retrieving patents across languages. We propose a multi-lingual patent retrieval system, which translates a user query into the target language, searches a multilingual database for patents relevant to the query, and improves the browsing efficiency by way of machine translation and clustering. Our system also extracts new translations from patent families consisting of comparable patents, to enhance the translation dictionary

The solubility of quartz in the aqueous sodium chloride solution at high temperatures and high pressures

The solubility of quartz in the aqueous solutions of 1, 3 and 7% sodium chloride concentration was measured at the temperatures up to 500℃ and at the packing ratios from 1/3 to 1/1.6ml/ml by observing the loss in the weight of quartz blocks in contact with the solution. The solubility of quartz in sodium chloride solution was larger than in water at temperatures above 280℃, and rose more rapidly with temperature than in water. Reproducible values were not always obtained at temperatures above 340℃ to the critical temperature in the same conditions, and the solubility values were roughly classified into three groups, higher, lower and intermediate. The results under supercritical conditions being considered as the effect of sodium chloride on the solubility of quartz in steam, it is shown that the smaller the density of steam is, the larger the effect of sodium chloride, and the effect can not be found when the density is sufficiently large. As the results the author gave some consideration on the effect. of sodium chloride on the equilibrium in the quartz-water system

The solubility of quartz in water at high temperatures ans high pressures

The solubility of quartz in water was measured at the temperature range up to 500℃ and at the pressure range up to 900 atm by observing the loss in the weight of quartz blocks in contact with water. The measurements were made along the three-phase boundary, quartz-gas-liquid, and in the two-phase field, quartz-gas, under supercritical conditions. The present values are generally lower than those already published, and the maximum value for the discrepancy is about 10 per cent. The solubility is proportional to the fugacity under supercritical conditions except the portion under higher pressures at temperatures below 420℃, provided that the temperature is kept constant
