This has lead to increasing availability of geographic context for the picture, videos and audio users share on the web. Such data has allowed systems to search through, browse and analyse media according to location without being wholly dependant on expensive manual annotation. However, the current extent of much geographic metadata consists of describing a single pair of coordinates per item. There is difficulty in encoding the multiple locations pertinent to the content of an image, the location of the camera, as well as handling the multiple locations that may be associated with sections of video. Current media retrieval systems use geographic indexing to return results that are relevant to an area defined as within the radius of a point or an official bounding box. This ignores the complexity of canonical geographic boundaries, as well as the colloquial nature of many commonly-referred to geographic points and areas, highlighting the relationship between these two complementary geographies. By addressing these current limitations, future geographic multimedia retrieval systems will be able to better support user engagement with media.","PeriodicalId":441886,"journal":{"name":"GeoMM '12","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130496244","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To date, models of location have ignored the differences between users. This paper focuses on one aspect of demographics, namely gender, and explores the relationship between gender and location in a large-scale corpus of geo-tagged Flickr images. We find that male users are much more likely to geo-tag their photos than female users, and that the geo-tagged photos of male users have wider geographic coverage than those of females. We create gender-based language models of location using the Flickr tags describing geo-tagged photos, and find that Flickr tags created by male users contain more geographic information than those created by female users, and that they can be located based on their tags far more accurately. Further, models created exclusively with data from male users are more accurate than those created from female users' data. Although our results suggest that there is some benefit from using gender-specific models, this benefit is quite minor, and is overwhelmed by the richer location information in the male data. The results also show that gender-based differences in location models are more important at the hyper-local level.","PeriodicalId":441886,"journal":{"name":"GeoMM '12","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131191087","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
