Multiple descriptions of location that a user lived in the past. From this analysis, we found that most users write something in their profile document but rarely their attributes. This makes it essential to estimate the user attributes. We also found that manual checking of the extraction results is inevitable because applying text matching method to a free-form text tends to yield a lot of noise. We then counted the number of statuses_count and analyzed how many tweets were, on average, available as an estimation resource.
It first finds users who have both Twitter and blog accounts (TwiBlo users) by using the URL described in the url field. It then extracts the attributes that a user specified in his/her blog as true labels of the training data in Twitter about the user. The extraction rules are predefined for each blog site and extraction script outputs user attributes when it is input the URL described in the url field.

It (ut ) = − log 35 kind(ut ) + α |Ft | . (3) Let u be a user with the user’s profile document up and tweets ut . As indicated by Eq. (1), final estimation probability P is obtained by aggregation of estimation probabilities from the profile document Pp and tweets Pt weighted by reliability scores Rp and Rt , respectively. Rp and Rt are calculated by self-information Ip and It that are obtained by the log ratio of the kind function’s value and the total number of kinds of features |Fp | and |Ft | shown as Eqs.
