INDIAN STATISTICAL INSTITUTE Documentation Research & Training Centre 8th Mile, Mysore Road, RVCE Post Bangalore, 560 059 DRTC Seminar-4 Geo-tagging & Spatial Indexing of Text-Specified Data ABSTRACT =========== Standard web search engines, traditionally, used to treat the geographical terms in the same way as other terms. This can result in failure to find relevant documents when there is ambiguity with the place names and names of organizations, people, buildings and streets. Librarians and bibliographers used to maintain authority files for disambiguating among them with proper choice of attribute sets. But, complexity increases when the data is unstructured as in news articles, blogs, tweets. For, successful execution of location-based and feature-based queries, the construction of spatial indices based on the spatial attributes is required, including the integration of text indexing with spatial indexing methods that exploit geo-tagging procedures to categorize documents with respect to geographic space. In this seminar, we will discuss about geo-tagging, possible spatial indexing structures and few research problems in this area.
