HERMES Components

HERMES Components

The HERMES project is subdivided into four parts. They are motivated by the process (dataflow) a model goes under while being reused. This process could be explained from start to end, but with the figure to the right in mind it is easier in reverse order.

Last, a model is actually reused (thumb up), but this means, it was found somehow in a larger collection of models. Hence, a component adapts ideas from recommender systems so "the right model" can be found and reused.

Second to last, collections of models where models are actually reused, will expose issues of single models over time. Certainly, these need to be fixed, discussed, or at least reasoned about. In other words, models evolve or mature over time (king).

First, collections of models are only as beneficial for reuse as they grow continuously and are feed with "good" models. But such models are only found in existing, real world models. Getting the reusable parts out of models preserving a low degree of redundancy it what model harvesting (shovel) should be all about.

Underneath, a persistence layer needs to provide functionality to store, query for, and retrieve models. But this persistence can come of different flavors. This depends on the size of the group working with this persistence (local, or remote, one or few users).

In a nutshell and now from start to end, a model is analyzed for reusable parts, which are harvested, i.e., stored in a model library. Of course, the newly harvested models might not be perfectly suited for reuse. Hence, they evolve in this model library and are offered for reuse after they matured to a certain degree.
  • Harvest Demo

    This video shows the basic functionality how models can be stored into a model library. The process takes "known" parts into account and links them to the newly stored.

  • Evolution Demo

    This video shows how the evolution approach assesses model quality and offers a staged approach that guides model quality.

  • Reuse Demo

    This video shows how models can be "applied", i.e., reused. They are loaded from a model library and inserted into the open editor. Several libraries and several editors are supported.
