Abstract

To enable an outdoor user to acquire mobile specific information, an information retrieval system should provide contents that reflect user's circumstance such as user's position and time. There are a lot of information services that can provide contents based on geographical location. But, about temporal information, there is few works, because there is no useful indexing method for time information. In this paper, we propose a crawler which collects temporal expressions by reading Exif data of photos on blogs. Because the Exif data has shooting time of photo, the proposed system is expected to have good precision with small granularity. As a result of evaluation, the precision of the proposed method reached 0.72 even though the proposed method adopts a simple algorithm.
