This paper defines a new structure which is a key component, the expanded entity phrase (EPx). This paper also presents an approach for extracting EPx's from free text. The structure of the EPx's facilitates quantitative comparison with other EPx's. A combination of part of speech-based template matching and ontology-driven NLP provides an effective technique for extracting complex entity structures that cross clause boundaries. This approach also uses ontology-based inferences to lay the ground work for linking EPx's for semantic relatedness assessments involving different named entities not explicitly stated in the text. The real world data used in this research were derived from a collection of law enforcement email messages submitted by hundreds of investigators seeking information or posting information about crimes, incidents, requests, and announcements. Performance data on the approaches used for extracting EPx's and links from this data are presented.","PeriodicalId":220165,"journal":{"name":"Proceedings of 2011 IEEE International Conference on Intelligence and Security Informatics","volume":"9 2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114001194","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}

Country risk has traditionally been assessed by monitoring economic and financial indicators. However, social media (such as forums, blogs, and websites) are now important transporters of citizens' daily conversations and opinions, and as such may carry discernible indicators of risk, but they have been as yet little-used for this task. The Geopolitical Web project is a research effort with the ultimate goal of developing computational approaches for monitoring public opinion in regions of conflict, assessing country risk indicators in the social media of fragile or weakening states, and correlating these risk signals with commonly accepted quantitative geopolitical risk assessments. This paper presents the initial motivation for this data-driven project, collection procedures adopted, preliminary results of an automated topical analysis of the collection's content, and expected future work. By catching and deciphering possible signals of country risk in social discourse we hope to offer the international community an additional means of assessing the need for intervention in or support for fragile or weakening states.","PeriodicalId":220165,"journal":{"name":"Proceedings of 2011 IEEE International Conference on Intelligence and Security Informatics","volume":"263 1-2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134628673","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}
