“…The increasing role of geotagged images and text in spatial decision making is covered in [8], and motivates approaches such as integrating geotagged citizen input from smartphones and desktops into GIS systems [9]; as these authors suggest, it is not a trivial task to automatically merge (incompatible) information into an existing GIS framework. In [10] the implications of usergenerated spatial content, especially using GPS-enabled smartphones, and crowdsourcing to add geotagged annotations, extensions and mashups to base maps (such as GeoWeb) are evaluated.…”

Abstract. As emergency first responders and commanders increasingly use mobile phones, tablets, and social media to communicate, coordinate, and manage information during disasters, we see a need and opportunity to provide a mobile device-appropriate semantic layer to a geographically-based common operating picture. The challenge is to provide a simple, usable structure for a rapidly growing body of information to simplify the development of situational awareness in an unfolding disaster. We use a hyperlinked structure based on the ASK model to organize information in a readily accessible form. In this paper we describe our initial design and experience with an Android-based prototype, supported by a Ruby on Railsbased repository service. Our prototype allows the incorporation, aggregation, assessment, and redistribution of dynamic human-generated and sensorderived information.

“…in providing timely information and analysis results of the occurring disaster. However, for the timely and available characteristics of the social data, the weakness can be reduced by the supplement of social data in disaster management [32,35]. Dorn et al [36] analyzed the effectiveness of orthophotos, LiDAR data, official land use data, OpenStreetMap data, and CORINE Land Cover data in flood simulations, and confirmed the usability of crowdsourced data.…”

Social media is valuable in propagating information during disasters for its timely and available characteristics nowadays, and assists in making decisions when tagged with locations. Considering the ambiguity and inaccuracy in some social data, additional authoritative data are needed for important verification. However, current works often fail to leverage both social and authoritative data and, on most occasions, the data are used in disaster analysis after the fact. Moreover, current works organize the data from the perspective of the spatial location, but not from the perspective of the disaster, making it difficult to dynamically analyze the disaster. All of the disaster-related data around the affected locations need to be retrieved. To solve these limitations, this study develops a geo-event-based geospatial information service (GEGIS) framework and proceeded as follows: (1) a geo-event-related ontology was constructed to provide a uniform semantic basis for the system; (2) geo-events and attributes were extracted from the web using a natural language process (NLP) and used in the semantic similarity match of the geospatial resources; and (3) a geospatial information service prototype system was designed and implemented for automatically retrieving and organizing geo-event-related geospatial resources. A case study of a typhoon hazard is analyzed here within the GEGIS and shows that the system would be effective when typhoons occur.

Users of the web are currently the main content authors. Social networks form a valuable source of large volumes of user-generated content that might be beneficial in different areas of research. In this paper, we exploit the data generated by users of micro-blogging services, in particular Twitter, for disambiguating terms and inferring possible taxonomies for terms. We conducted an exploratory study to test the possibility of inferring high-level categories and possible sub-categories for which terms might be included. This experiment exploits the collection of hashtags which are mentioned with a specific hashtag in Tweets text., and the Open Directory Project (ODP), in order to discover dynamic taxonomies for a term (hashtag) with no knowledge needed about the semantic meaning of that term. We present several experiments which we have used to test this method, and promising results are reported.
