Information collection and discovery tasks involve aggregation and manipulation of information resources. An information resource is a location from which a human gathers data to contribute to his/her understanding of something significant. Repositories of information resources include the Google search engine, the ACM Digital Library, Wikipedia, Flickr, and IMDB. Information discovery tasks involve having new ideas in contexts of information collecting. The information one needs to collect is large and diverse and hard to keep track of. The heterogeneity and scale also make difficult writing software to support information collection and discovery tasks. Metadata is a structured means for describing information resources. It forms the basis of digital libraries and search engines. As metadata is often called, "data about data," we define meta-metadata as a formal means for describing metadata as an XML based language. We consider the lifecycle of metadata in information collection and discovery tasks and develop a metametadata architecture which deals with the data structures for representation of metadata inside programs, extraction from information resources, rules for presentation to users, and logic that defines how an application needs to operate on metadata. Semantic actions for an information resource collection are steps taken to generate representative objects, including formation of iconographic image and text surrogates, associated with metadata. The meta-metadata language serves as a layer of abstraction between information resources, power users, and application developers. A power user can enhance an existing collection visualization application by authoring meta-metadata for a new information resource without modifying the application source code. The architecture provides a set of interfaces for semantic actions which different information discovery and visualization applications can implement according to their own custom requirements. Application developers can modify the implementation of these semantic actions to change the behavior of their application, regardless of the information resource. We have used our architecture in combinFormation, an information discovery and collection visualization application and validated it through a user study.

Over a decade ago, there was no standardised method for information sharing during emergency situations. Governments, first responders, and emergency practitioners often had to rely on what little technology that was available to them. This situation slowed down communications, putting entire recovery operations, and lives at stake. The Emergency Data Exchange Language (EDXL) is the umbrella standard for several emergency communication standards that are being developed to address this issue. The Semantic Web is slowly, but steadily becoming a natural extension of the present-day Web. Thanks to efforts from researchers, and corporations such as Google, Facebook, etc., we are seeing more, and more semantics aware applications on the Web. These applications have been successful in bringing Semantic Web technologies to the common user to a large extent. Semantic Web technologies have found applications in a wide range of domains, from medical research to media management. However, a study to see if EDXL messaging standards can benefit from Semantic Web technologies has not yet been made. In this thesis, we investigate the possibility of enabling Semantic Web technologies for EDXL standards, specifically the EDXL Resource Messaging (EDXL-RM) standard, and explore the benefits that can come out of it. The possibility of converting XML based EDXL-RM messages to semantic formats is explored at first. This step is achieved through the evaluation of existing tools and technologies. Based on the outcome of this study, an EDXL to OWL converter that works in two stages is developed. The motivation for enabling semantic support for EDXL standards is illustrated through several use cases.
