Dr. Rachael is a conversational agent, in the form of a virtual caregiver, for use in helping to identify rare diseases. The rationale for the system is grounded in the fact that rare disorders by their very nature are difficult to diagnose unless the caregiver or doctor is familiar with a wide range of these conditions. The conversational agent uses unstructured free-flowing natural language together with a large database of rare disorders, and is easily updatable by human caregivers without any technical expertise. Matching of users' comments with database entries is performed using a general cognition engine; which is able to understand natural language regardless of specific wording or grammar.

After each session, the user is provided with the most likely condition that the user or family member is thought to be at risk of, and a written pre-formulated general description is given, so that suitable health care services can be contacted. Each comment most of the time can relate to more than one condition so counters are kept, and when a given statement relates to more than one condition all conditions counters are increased by one. The final rating of the patient's likely condition is calculated based on which counter is largest, and where there is not sufficient confidence of a given diagnosis. The user can also see, at the end of the session, a short description of the condition(s) most likely to apply to the symptoms discussed. This feature allows the patient or the family to get a firm suggestion even if the session lasts a long time or is even completed over many sittings, hopefully helping in the right direction towards a suitable diagnosis.

This app uses a proprietary general cognition engine, able to “understand” natural language regardless of the specific wording or grammar used in any of the top 10 languages used in Internet and can do some basic first order logic, coupled to the virtual assistant for generating and processing material to help in the diagnosis and continuing support for those at risk of or living with a disease.

We believe that this app offers an attractive option for those who have a need for new, simple, online, confidential quick methods in the general area of e-Health as well as individual users or a professional who might be seeking support for an initial diagnosis as well as 24/7 support for patients.
