About Vistology

Vistology is a company that received a Department of Defense SBIR/STTR grant for a project entitled: Exposing Latent Information in Folksonomies for Reasoning. The abstract given for this project is as follows: User tagging by means of authority-free folksonomies has become standard for making online videos, photos, bookmarks and blog posts discoverable. We propose to develop a system that identifies and exposes the ontological structure that is latent in the folksonomic tags used in open, publicly available sites such as Flickr (photos), YouTube (video) and Blogger (blogs) and demonstrates the ability to perform higher order processing using the induced structure. Specifically, the technology developed will allow the system to identify photos, videos or blog posts about the same event by means of the tags applied in one medium (e.g. photos) in order to identify tagged items in another medium (videos or blog posts). We plan to use (i) the surrounding text, (ii) the user's other tagging practices, and, most importantly, (iii) large-scale topic hierarchies used in DMOZ, Wikipedia (dbPedia) and lexical resources such as Beth Levin's taxonomy of verb classes in order to tokenize and disambiguate the tags into unambiguous topics. These will then be mapped onto who, what, when, and where slots, and used to identify depictions of the same event in other media using a formal reasoner, VIStology's BaseVISor, a forward-chaining OWL/RDF reasoner using r-entailment.Vistology is a company that received a Department of Defense SBIR/STTR grant for a project entitled: Security Policy Reconciliation. The abstract given for this project is as follows: The Department of Defense Goal Security Architecture (DGSA) transition plan has established a framework and a long range road map for the implementation of security policies in the DoD information systems. DGSA establishes a number of requirements that should be implemented in order to achieve the goals of the roadmap. One of the requirements is that a representation for security policy rules be developed as well as tools to support policy management. Moreover, it stipulates that interpretation of security policies should be context dependent and the tools should support the security engineers in composing and reusing existing policies. Towards these goals, VIStology proposes to develop a formal, ontology-based representation for security policy rules that is amenable to policy reconciliation and composition. VIStology will analyze requirements for a policy representation language; review various representation languages and propose a language that will support easy policy representation, reuse, composition and reconciliation; propose tools for the support of policy management; develop initial prototypes of tools and policies, assess the usability of the proposed language and tools; develop a plan for the implementation and evaluation of a full-scale prototype of the proposed tools.
