In [6], we have proposed a solution for the organization
of a semantic document repository in a specific domain,
which manages semantic information related to document
content and supports semantic representation and
processing in document retrieval. The solution includes a
model called SDB (Semantic Base Document) with
problems, semantic processing techniques and advanced
search techniques based on measuring semantic similarity.
Theoretically, we have contributed to the development of
several models that can be used to design document
retrieval systems in many different knowledge domains.
These models include:
