Abstract—Semantic composition in distributional semantic models (DSMs) offers a powerful tool to represent word meaning in context. In this paper, we investigate methods to utilize compositional DSMs to improve word sense discrimination and word sense disambiguation. In this work, we rely on a previously proposed multiplicative model of composition. We explore methods to extend this model to exploit richer contexts.
This chapter explores the different sources of linguistic knowledge that can be employed by WSD systems. These are more abstract than the features used by WSD algorithms, which are encoded at the algorithmic level and normally extracted from a lexical resource or corpora. The chapter begins by listing a comprehensive set of knowledge sources with examples of their application and then explains whether this linguistic knowledge may be found in corpora, lexical knowledge bases or machine readable dictionaries.

The author builds on recent work that indicates that distributional models can in fact distinguish to some extent between semantic relations, and argues that (the right kind of) distributional similarity indicates property overlap, and proposes a probabilistic account of semantic knowledge that can learn from such data.

Grading word sense assignment is studied based on a recent dataset of graded word sense annotation and finds the task of labeling a word in context with the best-fitting sense from a sense inventory such as WordNet is difficult.

Lecture 2. Word meaning is studied by the branch of lexicology called semasiology. Usually meaning is defined as the realization of a notion (or concept, in other terms) by means of a definite language system.
The word: basic unit of lexicology The most important characteristics of the word : 1. The word is a unit of speech which serves the purposes of human communication. So the word can be defined as a unit of communication. 2. The word is the total of the sounds which compose it. 3. The word possesses both external and internal characteristics.
The word is a unit used for purposes of human communication, materially representing a group of sounds, possessing a meaning, characterised by formal and semantic unity and a capacity for grammatical employment. The word may be described as the basic unit of language. Uniting meaning and form, it is composed of one or more morphemes, each consisting of one or more spoken sounds or their written representation.
Types of meaning grammatical meaning (unites words into parts of speech) Ex. : goes, stops, works lexical meaning (individual for every word) Ex. : went, kissed, looked
Denotational and connotational meaning Denotational component expresses the notional content of the word, shows what the word refers to. Connotational component expresses additional meanings of the word which may be of different types: stylistic, evaluative (rational and emotional) and emotional, etc.
Types of connotational meaning Evaluative (rational and emotional) Ex. : brain Ex. : brock (“a scoundrel”) Cf. also: notorious – celebrated Emotional, or emotive connotation of the word is its capacity to evoke and express emotion ( duckling, darling (diminutive emotive value). Stylistic connotation shows the stylistic status of a word: neutral, bookish, colloquial, slang, etc.
Componential Analysis consists in decomposition of the word meaning into semes – minimal components of meaning, or elementary units of sense. archisemes differential semes Ex. : girl, woman, spinster
Motivation morhological (Ex. : leader, cranberry) phonetical (Ex. : splash, boom, chung, ching) semantic (Ex. : chain store, chain hotel, chain smoker) folk etymology asparagus sparrow grass полуклиника , спинжак→
Polysemy Ex. : do, go, see, etc. lexico-semantical variants of the word (LSVs) Primary and secondary meanings in the semantic structure of the word Table “a piece of furniture” “ a supply of food”, “an act of assembling to eat”, “a group of people assembled at a table”, etc. Meanings can also be direct and figurative, concrete and abstract, central and peripheral, general and special
Semantic changes. Causes: historical, or extralinguistic, and linguistic. villain ( « деревенский житель » → « негодяй » Tory « ирландский разбойник » → « член партии Тори » lord « хранитель хлеба » → « господин , владелец , etc. » Borrowing Ex. : “any animal”: Deer, beast (Fr. ), animal (Lat. ) Ellipsis Ex. : daily newspaper→daily Analogy catch “understand”, grasp ”understand”
The nature of semantic change Association Transference: 1) based on similarity linguistic metaphor: neck (of a human being) → neck (of a bottle). 2) based on contiguity (real connection between the two objects). linguistic metonymy: hands (“limbs of a human body”) → hands (“a worker”).
Metaphors Based on similarity between two physical objects (concrete to concrete metaphores): teeth of a saw, leg of a table, a goose (of a silly woman). Zoosemy. concrete to abstract metaphors: a ray of hope, a shade of doubt. different types of similarity: similarity of shape (tongue of a bell), function (leg of a table), position (foot of a page), character of motion (snail (of a sluggish person)), dimensions (dumpling (of a short, chabby creature)), value (dirt cheap). proper names → common names: Appolo, Don Juan, Othello. Structural metaphors: Time is money. Argument is war
Metonymy 1) instrument → agent: pen (“writer”); 2) consequence → cause: grey hair (“old age”); 3) symbol →the thing symbolized (crown “monarchy”) 4) material → the thing made from it (silver “money”) 5) container → the thing contained (to drink a cup); 6) name of a place → institution (Whitehall); 7) action → the object of action (my love); quality →the person possessing the quality (He is a talent).
Synechdoche is a variety of metonymy which consists in using the name of a part to denote the whole or vice versa: Hands are wanted; OE mete “food” →Mn. E meat “kind of food”.
Semantic change may result in the change of the range of meaning. narrowing (specialization) of meaning. OE fugol (“any bird”) → domestic bird (fowl) widening (generalization) of meaning. girl “a child of either sex → “a female child”.
The change of the connotational structure Degradation (pejoration) of meaning: the process when the object to which the word refers acquires negative characteristics, and the meaning develops a negative evaluative connotation. OE word cnafa (Mn. E knave) “a boy” → a “boy servant” → “a swindler, a scoundrel”. Elevation (amelioration): the development of a positive evaluative connotation. OE cwen (Mn. E queen) “woman” cniht (Mn. E knight) – “a young servant”
