Report on New Methods for Representing and Interacting with Qualitative Geographic Information, Stage 2: Task Group 1 Core Re-engineering and Place-based Use Case.

摘要

This report documents Pennsylvania State University's (PSU) research on place-focused analysis of microblogs, specifically Twitter. The first section of the report identifies three categories of location information related to tweets: the location where a tweet originates, places mentioned in tweets, and the profile location of the tweeter. The report summarizes previous research on location information and contributes new insights resulting from additional PSU analysis. The second section of the report focuses on the visualization of place information. Place trees, place clouds, and place-coreferencing are introduced in the context of the SensePlace2 system. The third section of the report summarizes the SensePlace2 system architecture enhancements required to support the dynamic visualization of Twitter location information, including the development of an innovative user interface coordination mechanism and implementation of faceted search using Apache Solr.
