For example, (one sense of) the noun "director" is linked to (one sense of) the verb "direct" from which it is derived via a "morphosemantic" link. The morphology functions of the software distributed with the database try to deduce the lemma or stem form of a word from the user's input.
Pronounced "A-star". A graph traversal and pathfinding algorithm which is used in many fields of computer science due to its completeness, optimality, and optimal efficiency. abductive logic programming (ALP) A high-level knowledge-representation framework that can be used to solve problems declaratively based on abductive reasoning. It extends normal logic programming by allowing some ...
For example, once you've seen an article such as 'the', perhaps the next word is a noun 40% of the time, an adjective 40%, and a number 20%. Knowing this, a program can decide that "can" in "the can" is far more likely to be a noun than a verb or a modal. The same method can, of course, be used to benefit from knowledge about the following words.
Authors also use placeholders for generic elements in schematicized parsing, such as may be used to illustrate morpheme or word order in a language. Examples include HEAD or HD 'head'; ROOT or RT 'root'; STEM or ST 'stem'; PREF, PRFX or PX 'prefix'; SUFF, SUFX or SX 'suffix'; CLIT, CL or ENCL 'clitic' or 'enclitic'; PREP 'preposition' and POS ...
When the prefix "re-" is added to a monosyllabic word, the word gains currency both as a noun and as a verb. Most of the pairs listed below are closely related: for example, "absent" as a noun meaning "missing", and as a verb meaning "to make oneself missing". There are also many cases in which homographs are of an entirely separate origin, or ...
Stemming is performed by inputting an inflected form to the trained model and having the model produce the root form according to its internal ruleset, which again is similar to suffix stripping and lemmatisation, except that the decisions involved in applying the most appropriate rule, or whether or not to stem the word and just return the ...
British linguist Michael K. Halliday proposes a useful dichotomy of spoken and written language which actually entails a shift in paradigm: while linguistic theory posits the superiority of spoken language over written language (as the former is the origin, comes naturally, and thus precedes the written language), or the written over the spoken ...
An orthography is a set of conventions for writing a language, including norms of spelling, punctuation, word boundaries, capitalization, hyphenation, and emphasis.. Most national and international languages have an established writing system that has undergone substantial standardization, thus exhibiting less dialect variation than the spoken language.
