Semiotics

Semiotics can be taken as the study of signs and how we relate them to meaning - any communication and any part of it.

Signs in this context are are anything that can be interpreted to have a meaning, including but not limited to sounds, motions, gesture, images.

(Meaningful things aren't even limited to things done intentionally. Signs that are present but not made intentionally are e.f. those used in medical diagnosis, as a symptom can be a a sign of a medical condition.)

In a practical sense we often still focus on words, yet the term is used in part to remind you these are far from the only meaning-carriers, even in diagolgue you consider to be word-based first.

Sign process is sometimes synonym for semiotics, arguably a more self-explanatory name to those not already deep in the theory.

Sign process is also sometimes a little more specifically meant as a "any process/activity that involves signs, and probably meaning".

You can argue that linguistics is mostly about intentional meaning, in a sense we try to keep compact and practical and structural, and semiology is a wider, more anthropological thing about any signs and symbols anyone may have used along the way.

As such, linguistics courses may skim over semiology, or use the term only for some of the more symbolic inbetweens we meet - analogy, allegory, metonymy, metaphor, symbolism, and also conduct, behaviour, and a lot of other sociology.

It also overlaps with philosophy, relating to structuralism, and more. (see e.g. Saussure)

Philology, Etymology

Etymology is the study of the history of words and phrases, primarily reporting use, change, transfer between languages and such, often comprising of finding and proving (or disproving) these genetic-like relations.

While it is focused a little less on meaning, it often ends up mentioning things in terms of morphology simply because a lot of carried meaning comes from morphemes.

The term is related to philology, which refers to the extensive study of historical linguistics, which may easily include many aspects of a language at a time - grammar, culture, relevant politics, and more.

You can usually see systematic differences between cognates between similar languages in terms of phonetics and meaning. Partly because of this, a game of guess-the-cognate plays a role in second language vocabulary aquisition. Of course, it's easy to guess false cognates and false friends this way and get rather confused.

Loaning across languages can introduce various cognate relations. Consider for example:

False etymology, folk etymology

People regularly guess at etymologies.

And, with some regularlity, incorrectly.

They may sound quite plausible, and some get a status similar to urban legend -- they just won't die even though they're not hard to falsify.

This also sometimes leads to changes how these words are used, which are essentially neologisms.

Cognates

Cognates are words that are related by origin, by common ancestry, but have started developing independently, and as such now have distinct meanings and etymologies.

Meaning may have drifted apart, or are similar and now serve to distinguish two similar concepts.

For example, the English skirt and shirt have a common Old English origin.

May be used to refer to cognates within a language, but note that words that sound about the same across languages, particularly those in the same language family, are also commonly considered cognates - often because of their common origin and their development within their language.

For example, the word 'night' looks and/or sounds similar between most Indo-European languages.

Various cognates grow from long-term development, from common origins that unites two languages in the language trees. For example, English and German are fairly closely related, while English and Spanish's common ground is mostly in Latin.

False cognates

False cognates are words that are thought to be similar, usually because they look and sound it, but do not share a direct or common root.

For example, Latin habere (to have) and German haben (to have) seem like likely cognates, but these two words come from different origins. Tracing them back reveals that their similarity is coincidental; the sounds changed over time, and from distinct origins.

Doublets (etymological twins)

Repeated loaning from the same origin, often at different times, creates doublets, a.k.a. etymological twins: words with the same origin, but that are made distinct in the loaning process.

Could be considered a special case of cognates.

Regularly have similar but distinct meanings and/or uses, often (near-)synonyms, sometimes (near-)antonyms.

For example, English has

fire and pyre,

aperture and overture

carton and cartoon,

and, less recognizably, sovereign and soprano

Triplets also exist, but are fairly rare.

False friends

False friends are words that look quite similar between languages, but significantly differ in meaning.

They are easily misidentified when the words are homonyms, or cognates (false or not).

False friend recognition probably happens most often across languages. Literal translation of regular sentences and especially idioms regularly introduces false friends.

Onomastics

Onomastics, also known as onomatology, is the study of names, and usually refers to its etymological aspects,like figuring out where they came from and how they evolved.

Not to be confused with Onomasiology (the means of expressing concepts).

Lexicology

✎ This article/section is a stub — some half-sorted notes, not necessarily checked, not necessarily correct. Feel free to ignore, or tell me about it.

Lexicology is the general and objective study of words and their meanings.

In some ways, it is the lexical part of philology.

In other ways it is closely related to etymology, phraseology, and semantics.

Lexicography can be said to be the applied part of lexicology, as it studies the use of words.

'Lexicography' is also and is often used to refer to the compilation of a lexicon. Note that lexicographer is a comparatively specific word, referring to someone who writes dictionaries.

Onomasiology

Onomasiology concerns itself with the means of expressing concepts in language - often in either the context of lexicology, or more widely in the sense of lexical semantics.

Not to be confused with onomastics/onomatology, the somewhat more specific study of names.

The distributional hypothesis

The distributional hypothesis is the idea that words that are used and occur in the same contexts tend to convey similar meanings - "a word is characterized by the company it keeps".

This idea is known under a few names,

latent semantic analysis

Latent Semantic Analysis (LSA) is the application of Singular Value Decomposition on text analysis and search.

random indexing

https://en.wikipedia.org/wiki/Random_indexing

Topic modeling

Roughly the idea given documents that are about a particular topic, one would expect particular words to appear in the each more or less frequently.

Assuming such documents sharing topics, you can probably find groups of words that belong to those topics.

Assuming each document is primarily about one topic, you can expect a larger set of documents to yield multiple topics, and an assignment of one or more of these topics, so act like a soft/fuzzy clustering.

This is a relatively weak proposal in that it relies on a number of assumptions, but given that it requires zero training, it works better than you might expect when those assumptions are met. (the largest probably being your documents having singular topics).

+: "this sentence probably says something about people moving"
+: "walk is like run, and to a lesser degree swim",
+: "I am making an ontology to encode these and would like some assistance to not forget things"

+and much esier to have ''tons'' of un-annotated data.
+It may pick up relations only softly, and in ways you can't easily fetch out,
+but it's pretty good at not missing them,
+meaning you don't have to annotate half the world's text with precise meaning

+You just feed it lots of text.
-Such a system doesn't need to know what pronouns or determiners are,
-to still encode a certain verbiness and nouniness as a result (other things it doesn't know),
-and from other contexts perhaps learn the tooliness as well.
-It is still going to learn the difference, and from text you do not need to annotate.
-Maybe you can get further with the same amount of well annotated data,
-but it is usually so much easier to find a lot more un-annotated data.
 There are limitations. It might pick up on more subtleties,
