Parent-Child relation --- useless?

It seems that Parent-Child relations should not be implemented in the core of PCnous.
It seems that Reason-Consequence relations are good enough for keeping all relationships between concepts.
Sibling (synonyms) search can be accomplished any time when it's necessary. Sibling search can be accomplished based on reason-consequence relations (cause-effect relations).

Reader prototype: Current status

Implemented:
1) Find statement in the text.
2) FindWords in a statement (and add them to WordDictionary).
3) FindPhrases in a statment (and add them to PhraseDictionary).
4) FindTextPairs (and add them to TextPairDictionary).

Not implemented:
1) Short memory.
2) Merge Method (which merges the Short Memory and the Main Memory)
3) Reason-Consequence relations
5) Forgetting process.
6) HTML parser/reader which will allow to find and to read big amount of information.

Why does Chatter need for TextPairs?

Question: What are TextPairs for? I read text pairs description and do not understand why you divide a sentence in such a way.

Answer:
I divide a sentence into: words and phrases.

But in order to remember "how correct natural language sentence looks like" I also
remember typical text pairs.

Text pairs are like the links in the chain.

TextPair table will help TextWriter to build sentence in a correct
way.

Please, ask me more if it is not clear.

Text pairs

For 3 words sentence there will be 6 text concepts.
3 words and 3 phrases.

3 TextPairs will be found:
word1 -> word2
word1 -> phrase2
word2 -> word3



For 10-words sentence there will be
10 words
9 two-word phrases
8 three-word phrases
7 four-word phrases
6 five-word phrases
(I don't consider phrases longer than 5 words)
=====================
Total: 40 Text copcepts in the TextConcept collection

There will be maximum 5 text concepts with the same "StartingPosition" key.

TextPairs search

Well, here is the task:

Sentence consists of words.
For instance, "Word1 word2 word3".
Words are grouped by phrases.
For example:
phrase1 = "Word1 word2"
phrase2 = "Word2 word3"
phrase3 = "Word1 word2 word3"

I consider both words and phrases as
text concepts.

Every text concept has a "start position" and an "next position".

I'm going to use "start position" as the key for text concept in the
collection.

As you can see, text concept "word2" has start position = 2
Text concept "phrase2" has start position = 2. That is the same with
"word2". That means duplication.

Original task is to find all text pairs in the specified sentence.

Any suggestions?
