In linguistics, semantic analysis is the process of relating syntactic structures, from the levels of words, phrases, clauses, sentences and paragraphs to the level of the writing as a whole, to their language-independent meanings. It also involves removing features specific to particular linguistic and cultural contexts, to the extent that ...
A prominent example is probabilistic latent semantic analysis (PLSA). Latent Dirichlet allocation , which involves attributing document terms to topics. n-grams and hidden Markov models , which work by representing the term stream as a Markov chain , in which each term is derived from preceding terms.
The use of Latent Semantic Analysis has been prevalent in the study of human memory, especially in areas of free recall and memory search. There is a positive correlation between the semantic similarity of two words (as measured by LSA) and the probability that the words would be recalled one after another in free recall tasks using study lists ...
Cross-language explicit semantic analysis (CL-ESA) is a multilingual generalization of ESA. [9] CL-ESA exploits a document-aligned multilingual reference collection (e.g., again, Wikipedia) to represent a document as a language-independent concept vector.
SemEval (Semantic Evaluation) is an ongoing series of evaluations of computational semantic analysis systems; it evolved from the Senseval word sense evaluation series. The evaluations are intended to explore the nature of meaning in language.
Conceptual semantics is a framework for semantic analysis developed mainly by Ray Jackendoff in 1976. Its aim is to provide a characterization of the conceptual elements by which a person understands words and sentences, and thus to provide an explanatory semantic representation (title of a Jackendoff 1976 paper).

ESA (explicit semantic analysis) based on Wikipedia and the ODP; SSA (salient semantic analysis) [48] which indexes terms using salient concepts found in their immediate context. n° of Wikipedia (noW), [49] inspired by the game Six Degrees of Wikipedia, [50] is a distance metric based on the hierarchical structure of Wikipedia.
