Abstract
Abstract Nowadays, a large part of the multimedia data on the Internet is generated with devices that automatically annotate them with location information However, free-form content on websites does not implicitly contain any geographical information. This is the biggest challenge for building a location-aware search engine. In this paper, we study how to extract location-aware information from the web. The key challenges are to detect location from a web page and to extract relevant information related to that location. We detect locations by identifying postal addresses using freely available gazetteers. Additional information for summarising the search results are titles and representative images, which we mine from the content using simple rule-based approaches utilising the structure of web pages. This information can be used to personalise search results for mobile users so that the results are relevant to their location.
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
