Twitter User Gender Inference Using Combined Analysis of Text and Image Processing

Profile inference of SNS users is valuable for marketing, target advertisement, and opinion polls. Sev-eral studies examining profile inference have been reported to date. Although information of various types is included in SNS, most such studies only use text information. It is expected that incorporating information of other types into text classifiers can provide more accurate profile inference. As de-scribed in this paper, we propose combined method of text processing and image processing to im-prove gender inference accuracy. By applying the simple formula to combine two results derived from a text processor and an image processor, significantly increased accuracy was confirmed.
