approximately 90 s, with an additional 10 min to set up all the virtual machines.
This compares rather well to the almost 20-h processing time on a single processor.
Users can access the portal via a web-based GUI. After successful login, users
can upload the documents to be processed, and start processing them by accepting
the calculated cost. The processed contents, including signatures, OCRized contents
and metadata, can be downloaded from the portal.
19.3.4 Further Development Plans
The
first release of the eDOX Document Archiver Gateway collects document type
independent sets of the metadata, as was explained earlier. Future releases will
consider more sophisticated approaches, such as form recognition, for example.
This method can identify metadata that is dependent on various document types and
will be more helpful searching information in documents, such as:
Invoices [invoice no., issuer, company, price per unit, total price],
Salary documents [name, birthday, year],
Sickness/bene
t documents [name, birthday, year],
Employment contracts [name, year, job],
Delivery notes [date, ID, order ID, company name],
Ledger documents [year, period],
Balance sheets [year, period],
