From lojban@cuvmb.cc.columbia.edu Sat Mar 6 22:59:04 2010 From: lojban@cuvmb.cc.columbia.edu To: u7911005@cc.nctu.edu.tw Date: Sat Oct 30 00:11:57 1993 X-From-Space-Date: Sat Oct 30 00:11:57 1993 X-From-Space-Address: lojban@cuvmb.cc.columbia.edu Message-ID: I'm responding today because I just ran across your post on comp.ai.nat-lang regarding subjects and objects, dated 16 Jun. Your posting was interesting because in Loglan/Lojban it is indeed true that there is little difference between a noun and a verb. In your post, you make the following definitions: >When we analyze a sentence using predicate logic (i.e., >arrest(sheriff(), Charlie())), I think we can take everything as a >function, so: A noun would be a function without arguments; and a verb >or an adjective would be a function with one or more arguments. And the >"subject" would be the "first argument" of the verb function, which (as >you pointed out) doesn't have to be the "active argument" at all. In Lojban we could not even say this much. Nouns may also have arguments in Lojban (and I suspect in other languages as well) For "sheriff", the obvious arguments are the person who fills the role, and the place he is sheriff of: sheriff(John(), Nottingham()). So [arrest(sheriff(John(), Nottingham()), Charlie())] would seem to be the formalism I want. In Loglan/Lojban we attach the Nottingham onto the sheriff easily, and in a way identical to an option way of attaching arguments to the main predicate (verb). Using English content words in the Lojban, this gives: le sheriff be la Nottingham bei fa la John cu arrest be la Charlie. noun noun"object" noun "subject" ---------------------------------------------- ------ ------------- verb subject verb verb object Note that in this case I expressed the 'subject' in 'VOS' order, probably most natural if one were to actually express the sentence this way in Lojban which is unlikely. Rather, as in natural languages, we tend to express further information about the noun in the form of relative clauses or relative phrases that attach to the noun but analyze independently from it. Loglan/Lojban allows the option of going either way. However, my statements are a little misleading, because in analysis we came to a different conclusion. 'Nouns' in Lojban, which are the arguments of the various predicates expressed in the language, are either names (i.e. labels), pronouns, or "descriptions", which themselves are verbs WHICH ARE EXPRESSED IN TERMS OF THEIR FIRST ARGUMENT. i.e. "Sheriff of Nottingham" is a reference to the first argument of the function 'Sheriff()', which is the person filling the job. We are describing that person by expressing another verb about him wherein he serves the first argument. It is abnormal therefore to express the first argument of such a noun overtly as I did in more early pseudo-Lojban sentence mentioning "John", Though it is permitted. Normally in English (I don't know about other natural languages), an appositive is used to express such a first argument since it is just ANOTHER expression of the same first argument that the descriptive argument itself is providing. Lojban allows it in all three ways: as appositive, relative clause/phrase, or attached as a direct expression of the first argument as I did in my pseudo-Lojban above. Interesting about this analysis is that it assigns a special grammatical role to the first argument - i.e. it is what enables a verb to be turned into a noun, (or actually, a predicate into an argument). Thus we could label this first argument "subject" and it would be useful and meaningful as a label. But in Loglan/Lojban, that first argument need not be agent, passive, or any other particular semantic role in the sentence - it just is the first argument of the referenced predicate, whatever role may be played by that argument. In most Lojban "active verbs" the first argument is indeed an agent, but there are some where it is not, and reordering the places is a simple grammatical function with no defined semantics beyond that reordering (we label this re-ordering "conversion", and its usual purpose is indeed to move an argument not naturally in the first position to that position so it may be used in an argument). In Lojban words that equate to English nouns or adjectives, the first argument is typically the thing that is labelled by the noun or described by the adjective, but there are usually other arguments defined as well (a standard or observer for many 'adjectives' for example). But this is only when we look at these words with an English eye. For the sentences expressing sheriff(John, Nottingham) and blue(eye, some_standard), we can look at these as verbs just as easily as nouns or adjectives. The resulting English is strange, but understandable: John sheriffs at Nottingham. -------- The eye blues according to some standard. ----- where I have underlined the odd verb form of the "noun" and "adjective" respectively. Thus, I think I agree with you that: >As I said above, the "everything's a function" (i.e., lambda calculus) >concept, when applied to designing (artificial) languages, can result in >no distinctions between nouns and verbs being needed. And Lojban indeed avoids some ambiguities of natural language through this practice, though far more are avoided by the structures of the formal grammar, which genrally act as parentheses that may be elided when unnecessary. Note that we get a special definition for "subject" based on its logical position, but otherwise the distinction is between predicate=function and argument=object. Lojban thus can be attributed an ordering by saying that an argument being a subject is thereby not an object, while all the rest of the objects keep that label. By this rather arbitrary standard the unmarked order for Lojban is either SVO or SOV with preference generally determined by the order of ones natural language (hence most commonly SOV due to English influence, these days, but it doesn't have to be.) But the markings necessary to support any of the other orders is relatively minimal, and, for example, certain predicates (those which in English are expressed as subjectless modals, e.g "It's possible that I am coming" are often expressed in VSO order even though the form is marked by a single word. But this abnormal order is not mandatory. As for your request for information: I sent to you several files, including our electronic form of the brochure, a minilesson, an article on Lojban's applications in lingustics, a 6-part grammar summary, an order form for our materials, and a description of how to use the Planned Languages Server to get many of those materials via email, although the formatting is often not screen-friendly or garbled in electronic versions. If you got the order form, then you should know the prices that we charge on international orders. We can accept cheques or Master Card/Visa credit card orders, but we pass the fees we pay for these services on to you. If the costs are too high for you, you can ask for help and state your intentions regarding learning/using the language in your work and we may be able to send you materials at a reduced cost or for free. Since we are interested in spreading Lojban around the linguistics community and overseas (the latter reducing English speaker biases during these formative years of the language), we try to accomodate people who need help, but our resources are pretty sparse. Because, as you may know from the Scientific American article on Loglan, Chinese played a significant role in the creation of the set of root words for the language according to a weighted phoneme algorithm, Lojban words are supposed to have a decided Chinese flavor to them. But with no Chinese speakers of the language, we don't know whether the high Chinese "recognition scores" really mean anything to a Chinese learner. We thus are especially interested in encouraging anything that will open doors into China, both Taiwan and the mainland, to gain access to the enormous and possibly extremely interested potential speaker-base. Any help you could give us in this, recruiting additional people there to learn the language, distributing copies of any material we send you to them (possibly splitting the cost if you are paying - we do not charge for permission to copy and distribute our materials in other countries so such cost-sharing may make it easier for long-term involvement in the Lojban community), helping us get materials translated into Chinese and getting such materials distributed, and formal research that leads to published linguistics and NLP papers in which Lojban plays a significant part, are all factors that would make us extremely interested in working with you. That you posted material that reveals an interest and insight into aspects of language that match those we are working on means that we should be able to find some further common ground. Thank you for your inquiry, and I look forward to your response. lojbab
