By dynamic I mean all of  the following interpretations:

1- Hasti learns ontology elements (which I call Ontels
and consists of concepts, relations and axioms) incrementally.
It may add new ontels, change and modify existing ontels or
delete ones by learning more and more. In other words it learns
in a non monotonic manner. Receiving new texts and new
knowledge may cause it to re-interprete what it knows.

2- Hasti tries to find knowledge about what it needs to know. As it  is
mentioned in section 4.2.2 it may generate tests to extract or prove
paradigmatic similarities between two concepts. The tests may be
evaluated by a human or be searched for in the future texts.so Hasti
can read texts with the aim of finding an answer to its questions.

3-   As the paper describes the world can be conceptualized from
several different perspectives and we may have various views of
concepts and relations and so various ontologies. A system may
contain all or some of these viewpoints in the same time and use
any one on demand. This property have been considered in the
design of Hasti. Suppose your ontology as a graph with different
colored weighted nodes and links. each color may be the
representative for a perspective or for a domain and weights show
the importance or relevance factor of the ontel to that perspective
or domain. when you use the ontology in a specific domain or
specific perspective or even specific ideology, you can just see the
corresponding colors. or if you suppose them to be linked by
various threads it seems like you drag a thread and all linked
ontels to the thread remains and others will fall. the remained
ontols (linked by the thread) are the needed ontology for your task.
This idea is under development in Hasti.
