Re: [agi] Context dependent words/concepts
This is one of the main concepts / problems of AI, is it not? Removing the ambiguity from our language in order to understand it. So you could remove it on the KR side, but you would still need to convert the regular language into the KR language, unless you would propose to have all inputs and outputs in the new KR language alone.So that conversion process would have to handle the context and ambiguity of the system still. And this is something we havnt accomplished to a high enough degree yet, but we have given it some attention, and realize that that alone is not enough.What kind of mapping would the KR need extra to handle the relationships between these newly seperated terms.JamesThe 'language' used in KR need not be context-dependent or ambiguous. If the blackboard is recognized (by the sensory perception module) as 'black', that would be the best description in KR, because that's the limit of sensory perception. Of course, normally the AGI will have more details of the board such asbetter color discernment, and that the board has a frame, etc. I still think the KR language does not need context-dependency or ambiguity. Except ambiguities with respect to the external world, which always exist.

[agi] Context dependent words/concepts

Well, no. It is true that NL has unnecessary ambiguities, but it is NOT true that a good knowledge representation will remove ALL ambiguities. Complete removal of ambiguity is an unachievable ideal, and trying to approach it too closely results in massive increase in the complexity of representations.Some degree of ambiguity is often useful to achieve representational compactness. And, context is not just about words having different meanings --- it's about concepts having different meanings in different situations ... which need to be determined **on the fly** by a contextualizing process, and can't be pre-figured up-front by decomposing every concept into a set of context-specific subconcepts... Let's take the examples: -apple piemeans a pie with apple fillings. - pizza pie is a pie that islikepizza (not a pie with pizza fillings). - apple juice means a juice made from apples. In #1 #3, I don't see how you can generate the target concepts merely by mixing apple with pie/juice on the fly. In all these cases, the target concepts areactually complex concepts that are first defined in episodic memory (eg we know that there is this thing which is a pie with apple fillings, and this thing is mapped to the phrase apple pie by the natural language processor). So, complex concepts are formed in episodic memory first, using an internal representation that is unambiguous, because they are formed from and groundedby experience (ie sensory processing).

Not all concepts are formed in episodic memory, of course.. Well, once again the distinction between NL (natural language) andKR (knowledge representation) is important here. Determining what is themeaningof mushroom pieis an NL -- KR problem. In this case a heuristic rule like try to construct the meaning of a compound word XY by looking for words like X'Y where X' is similar to X may be applicable. So NL can be ambiguous, KR is not. Within KR itself, we can form novel concepts out of existing ones, and this operation is not dependent on NL. For example I can form the concept unfair justice.
