Current Research

Research undertaken after my formal retirement focuses on valuation of the intangibles inherent in software after it has been developed, and the relationships of software maintenance in the retention of its effectiveness and value. Most applications are related to offshoring.

Published results are listed in my publication list and on-going work can be found as work-in-progress.

Past Research Projects and Activities

revolved around Large-scale Interoperation, Mediation, and Composition (LIC).

For instance:

• Managing ontologies in the context of the Semantic Web. A major project is the OntoAgents, a project under Stefan Decker's guidance within DARPA's DAML effort. An earlier project, being integrated with OntoAgents is Scalable Knowledge Composition(SKC), supported by AFOSR, which is developing an Ontology Algebra to assure scalability in the interoperation of many, heterogeneous resources.
• Compiling High-level Access Interfaces for Multi-site Software (CHAIMS), initially supported by DARPA ITO in the EDCS program, and now continued with support from ORD and CIFE.
• Access to and Formalization of Building Regulations, Supported by NSF ITR, at CIFE, Dept. of Civil Engineering. See REGNET, under direction of Professor Kincho Law, CIFE. The REGNET project is being initiated, and is looking for an interested and capable student.
• Protection of Privacy in Collaborative Settings. The novel concept is symmetric protection of access and release of information.
  Earlier work, now in technology transition state, developed security mediators for Trusted Interoperation of Healthcare Information and Secure Access Wrappers (SAW) for manufacturing data.
  
• Research in privacy protection provided checking the contents of images (TID). This work is carried out under the aegis of the NSF Digital Library II initiative.
  This latter task relates to our general research into the processing and content-based retrieval of image data, stored in on-line Digital Libraries.
• Application of mediating and security technologies in a repository, PharmGKB, to document linkages of phenotypic observations in patient populations to genotypic findings.
• A Simulation Access Language (SimQL) enabling integration and reuse of simulations within information systems. While I am not active in this area nopw, I still believe it will be a fruitful new area for future research and application.
• A meta issue for all these efforts is improving the transition of technology into practice, which is best accomplished through early engagement and support to companies who can help in development and then serve as demonstration and transfer sites to end-users.

Publications:

Many recent or important papers, as well as many viewgraphs, are available to net browsers. An up-to-date list of all my papers is also available. A list of pointers to abstracts for presentations is also available.

Research bibliographies I collected of current and past (pre 1991) work by others related to my interests are also available.

I keep accessible some work-in-progress, not for general distribution. My general policy is that readers are free to peruse all my files that are not specifically access protected, but if material is used, I request that appropriate credit is given.

Gio also participates, with Voy, in setting up educational Computer Exhibits for the Computer Science Department in the Gates building. We update the exhibits on an incremental basis. A photo tour, based on the exhibits as of July 1999, is now on-line. We are also building a forest of Stanford faculty student trees. Suggestions are welcome.

Gio maintains a Movie database {films, directors, actors, roles, remakes, studios} which has been been used for class projects as well as for fun. It has information on about 10 000 mainly classical or weird movies and their history.
