Databases
The concept of the Tox-Hub system relies on the idea that existing external information does not need to be duplicated.
We simply need to know where information is stored and how to access it. To that purpose, external databases are scanned, their contents analyzed and keywords extracted and carefully classified.
Every selected keyword is associated with a web-link of the external database where the original information related to it can be found. The Tox-Hub thus simply keeps “keyword/weblink” combinations (called “references”) which are readily accessible to the user. This constitutes the so called “internal or built-in dictionary”.
The process is programmed to be continuously running so that the references are revisited at a programmed schedule and thus permanently updated. This iterative process also ensures that any refinement introduced in the text processing, can be easily and quickly incorporated without any need of resetting the system.
About 20 external databases are currently available to the user from the Tox-Hub platform, though not all of them have the same searching possibilities.
They were carefully selected based on expert judgment and access feasibility. External databases presently accessible from Tox-Hub are listed in the table below
