Up to now many medical record softwares were not mach more than narrative reports of what did appen at some time in the past in some specific context. Student can find much static knowledge on internet, but have to learn a “medical methodology” about how to use this large amount of knowledge.

Evolution to a “task oriented model”, to help to solve patients health problems. Visual support of "Natural Intelligence". Focus on the relations between medical concepts. Intended for the training of students. Mind synchronisation between the members of care teams across Internet

We recently released a graph algorithms library for Neo4j.

You can use these graph algorithms on your connected data to gain new insights more easily within the transactional database and to improve query results from your graph data, for example by focusing on particular communities or favoring popular entities.

We developed this library as part of our effort to make it easier to use Neo4j for a wider variety of applications. Many users expressed interest in running graph algorithms directly on Neo4j without having to employ a secondary system.

We also tuned these algorithms to be as efficient as possible in regards to resource utilization as well as streamlined for later management and debugging.

In this session, we'll look at some of these graph algorithms and the types of problems that you can use them for in your applications and the implementation choices we made.

We want to present the openCypher project, whose purpose is to make Cypher available to everyone – every data store, every tooling provider, every application developer. openCypher is a continual work in progress. Over the next few months, we will move more and more of the language artifacts over to GitHub to make it available for everyone.

openCypher is an open source project that delivers four key artifacts released under a permissive license: (i) the Cypher reference documentation, (ii) a Technology compatibility kit (TCK), (iii) Reference implementation (a fully functional implementation of key parts of the stack needed to support Cypher inside a data platform or tool) and (iv) the Cypher language specification.

We are also seeking to make the process of specifying and evolving the Cypher query language as open as possible, and are actively seeking comments and suggestions on how to improve the Cypher query language.

The purpose of this talk is to provide more details regarding the above-mentioned aspects.

In this talk, Michael Hunger is going to shed some light over the new High Availability architecture for the popular Neo4j Graph Database. We are going to look at the different variants of the Paxos protocol, master failover strategies and cluster management state handling. This piece of infrastructure poses non-trivial challenges to distributed consensus-finding, an interesting session for anyone into scalable systems.
