Text analytics

Text analytics is a search engine for IUCLID data and attachments. It is installed separately from, but connected to, an instance of IUCLID. It allows rapid and sophisticated searching of all IUCLID fields including the text content of attachments. Searches can be carried out on both structured data such as picklists and dates, and on unstructured data such as free text fields and attachments.

Text analytics indexes all the information from IUCLID dossiers using elastic search, which provides for high levels of performance. Text analytics also carries out optical character recognition (OCR) on scans within attachments. Instance-Based Security (IBS) is supported. Both Text Analytics and the installation of IUCLID 6 Server to which it points must both use an Oracle database. This is not supplied with Text Analytics.

In version 3.8.0 the creation of queries has been improved. Queries can either be built up from preformed templates, or custom queries can be created with the help of a new feature that automatically proposes the correct syntax. See the release notes for a summary of changes, and the user manual for detailed descriptions.

The current version is not affected by the vulnerability in log4j that was announced in 2021.

Hardware requirements for a large IUCLID database are presented below; assuming that the Wildfly Server and Elastic Search Server are installed on the same host.

  • CPU: 6
  • RAM: 16 GB (4 GB Wildfly Server, 4 GB Elastic Search Server,  8 GB OS and Tesseract)
  • HDD: 50 GB

The IUCLID 6 Server and its database can also be hosted on the same server. The hardware requirements vary according to the amount of data managed by IUCLID.
