(1) SMU_NAME slot: SUM slot for short, is the conceptual description of the
SMU, usually a word or a phrase.
(2) Constraint slots: CON slots for short, are the restraints on the SMU.
Usually, they are just restraints on the description of the SMU and not in a
structural manner. In addition, each constraint includes a CAS facet
linked to a THY facet.
(3) Taxonomy slots: TAX slots for short, define some parents and sons of
this SMU in its involved taxonomy systems. So, they describe the
classification among the nodes in the memory network.
(4) Causality slots: CAU slots for short, define the cause and effect
connections to other SMUs. The SUM may be other SMU's cause, or the
effect of other SMUs. So, they describe the cause and effect connection
among the nodes in the memory network.
(5) Similarity slots: SIM slots for short, define the SUMs similar to the SUM
and describe the similarity among the nodes in the memory network.
(6) Partonomy slots: PAR slots for short, define the SUMs with whole-part
relation to the SUM.
(7) Case slots: CAS slots for short, define the set of cases relevant to the
SUM.
(8) Theory slots: THY slots for short, define the theory about the SUM.
The above eight kinds of slots can be divided into three classes. The first
is about the inter-SMU relations, including TAX slots, CAU slots, SIM slots,
and PAR slots; the second type is about the content and characteristics of the
SUM's own, including SMU slot and THY slots; the last type is about the
information of cases related to the SMU, including CAS slots and CON slots.
As for similar SMUs, we introduce a special kind of nodes, i.e., the intension
nodes MMU to express the fact that the SMUs linked to the SMU have
similar intension with the SMU. Knowledge more special can be stored near
the SMU by adding additional restraints to the SMU and hence a lot of
knowledge can be retrieved through the corresponding SMU. This makes
memory of knowledge layered into levels. PAR slots do not influence the
retrieval of knowledge in our model, yet they play an important role in the
recall of knowledge. Through the whole-part connections, we can recall the
knowledge of a certain theme or a certain field. The memory in THY slots is
about the theories about SMU, e.g., the knowledge of “resource conflict”. The
knowledge can be represented by any ripe representation methods, such as
