Part-Whole relationships. Part(s) describing surronding Whole.
The idea is to develop kind of data structure, with parts nested compounding
a whole, and the inner parts of the structure knows, in reverse order, the
containing tree of elements or structure around it.
1: Definitions:
1. *superPart:* Part containing one or more parts.
2. *part:* Inside a superPart. Can contain subParts.
3. *subPart:* Inner unit inside a part.
4. *NID:* Nesting level ID (deep level entities are in a nested/tree
structure)
XML Example:
<superPart NID="0">
<part NID="1">
<subPart NID="2">
</part> <!-- end NID 1 -->
</superPart> <!-- end NID 0 -->
5. *SeqID:* Sequence ID (symbol sequencing and identification)
Symbols sequencing and identification begins with first occurrence of
a symbol in a structure, begining with 0, next symbol is tagged with 1. If
next symbol appeared before, then the tag used before to identify it is
used.
6. *OccID:* Occurrence ID
Times element appeared in a sequence. First time same element occurs
is 0, then 1, etc.
7. *CID:* Count ID (0, 1, 2, ...)
Sequential count, begining with 0, of elements in determinate context
(Nesting level, Sequence, etc.)
8. *MvtID:* Movement ID
Signals start (S), inside (I), outside (O) or end (E) movement in a
statement chain.
2. Example:
- Linear Form:
( superPart ( part ( ( superPart ) ( subPart ( part (
superPart ) ) ) ) )
NID: 0 1 2 2 3 4
SeqID: 0 1 0 2 1 0
OccID: 0 0 1 0 1 2
CID: 0 1 2 3 4 5
MvtID: S I O I O E
- XML Example:
<superPart NID="0">
<part NID="1">
<superPart NID="2"/>
<subPart NID="2">
<part NID="3">
</superPart NID="4">
</part>
</subPart>
</part>
</superPart>
- Another Example:
( head ( face ( ( head ) ( eyes ( face ( head ) ) ) ) )
NID: 0 1 2 2 3 4
SeqID: 0 1 0 2 1 0
OccID: 0 0 1 0 1 2
CID: 0 1 2 3 4 5
MvtID: S I O I O E
3. Composite IDs:
Combining CID, NID, SeqID and OccID, other IDs for easier retrieval of
elements in statement can be achieved.
For example: NID + OccID = CID (Count of elements inside a specific nesting
level)
( head ( face ( ( head ) ( eyes ( face ( head ) ) ) ) )
NID: 0 1 2 2 3 4
SeqID: 0 1 0 2 1 0
OccID: 0 0 1 0 1 2
CID: 0 1 2 3 4 5
OrderID: (0.0) (1.0) (2.0) (2.1) (3.0) (4.0)
4. Terms (Parts) Relationships and Roles:
In specific context of container part, another part plays a role or function
in the context of container part. This is the semantics of the containment
relationship, for example: John, inside a specific Team, is a player, more
specificaly, a goalkeeper.
Parsing Example:
[previousElement]:[role/type] => [actualElement]:[role/type] =>
[nextElement]:[role/type]
5. Measurement units:
superUnit (eg.: Kilometer)
unit (eg.: Meter)
subUnit (eg.: Centimeter)
Ratio:
superUnit (1) => unit (1/n) => subUnit (1/n : n)
