Effectiveness of Context-Aware Character Input Method for Mobile Phone Based on Artificial Neural Network
Opportunities and needs are increasing to input Japanese sentences on mobile phones since performance of mobile phones is improving.
Applications like E-mail, Web search, and so on are widely used on mobile phones now.
We need to input Japanese sentences using only 12 keys on mobile phones.
We have proposed a method to input Japanese sentences on mobile phones quickly and easily.
We call this method number-Kanji translation method.
The number string inputted by a user is translated into Kanji-Kana mixed sentence in our proposed method.
Number string to Kana string is a one-to-many mapping.
Therefore, it is difficult to translate a number string into the correct sentence intended by the user.
The proposed context-aware mapping method is able to disambiguate a number string by artificial neural network (ANN).
The system is able to translate number segments into the intended words because the system becomes aware of the correspondence of number segments with Japanese words through learning by ANN. The system does not need a dictionary. We also show the effectiveness of our proposed method for practical use by the result of the evaluation experiment in Twitter data
Re-calibration of SDF/SXDS Photometric Catalogs of Suprime-Cam with SDSS Data Release 8
We present photometric recalibration of the Subaru Deep Field (SDF) and
Subaru/XMM-Newton Deep Survey (SXDS). Recently, Yamanoi et al. (2012) suggested
the existence of a discrepancy between the SDF and SXDS catalogs. We have used
the Sloan Digital Sky Survey (SDSS) Data Release 8 (DR8) catalog and compared
stars in common between SDF/SXDS and SDSS. We confirmed that there exists a
0.12 mag offset in B-band between the SDF and SXDS catalogs. Moreover, we found
that significant zero point offsets in i-band (~ 0.10 mag) and z-band (~ 0.14
mag) need to be introduced to the SDF/SXDS catalogs to make it consistent with
the SDSS catalog. We report the measured zero point offsets of five filter
bands of SDF/SXDS catalogs. We studied the potential cause of these offsets,
but the origins are yet to be understood.Comment: 36 pages, 19 figures(128 EPS files), PASJ accepte
