What does disambiguation mean on Wikipedia?

the process of resolving conflicts

What is a disambiguation link?

Disambiguation pages with links is a project that patrols the incoming links to disambiguation pages. These non-article pages exist to clarify and ease confusion in cases where two or more similarly named articles exist—for example, if two or more notable people have the same name.

Is disambiguation a real word?

Disambiguation refers to the removal of ambiguity by making something clear. Disambiguation narrows down the meaning of words. This word makes sense if you break it down. Dis means “not,” ambiguous means “unclear,” and the ending -tion makes it a noun.

What is disambiguation in NLP?

Word sense disambiguation, in natural language processing (NLP), may be defined as the ability to determine which meaning of word is activated by the use of word in a particular context. Lexical ambiguity, syntactic or semantic, is one of the very first problem that any NLP system faces.

What does word sense mean?

In linguistics, a word sense is one of the meanings of a word. People and computers, as they read words, must use a process called word-sense disambiguation to find the correct meaning of a word. This process uses context to narrow the possible senses down to the probable ones.

How do you use word sense disambiguation?

Two (or more) words are disambiguated by finding the pair of dictionary senses with the greatest word overlap in their dictionary definitions. For example, when disambiguating the words in pine cone, the definitions of the appropriate senses both include the words evergreen and tree (at least in one dictionary).

What are the key heuristics of Yarowsky algorithm?

This method, hereinafter referred to as the Yarowsky algorithm, uses two main heuristics: (i) one sense per collocation, meaning that words co-occurring with the target give strong clues about its correct sense, and (ii) one sense per discourse, by which it can be assumed that the target has the same sense in multiple …

How does Lesk algorithm work?

The Lesk algorithm is based on the assumption that words in a given “neighborhood” (section of text) will tend to share a common topic. A simplified version of the Lesk algorithm is to compare the dictionary definition of an ambiguous word with the terms contained in its neighborhood.

What are the application of word sense disambiguation?

WSD is basically solution to the ambiguity which arises due to different meaning of words in different context. For example, consider the two sentences. “The bank will not be accepting cash on Saturdays. ”

What is supervised word sense disambiguation?

Supervised Word Sense Disambiguation (WSD) systems use features of the target word and its context to learn about all possible samples in an annotated dataset. In supervised WSD, word embeddings can be used as a high-quality feature representing the context of an ambiguous word.

What is gloss in thesaurus of word sense disambiguation?

Word Sense Disambiguation (WSD) aims to identify the correct meaning of polysemous words in the particular context. Therefore, we propose GAS: a gloss-augmented WSD neural network which jointly encodes the context and glosses of the target word.

What role does Bayesian statistics play in word sense disambiguation?

Word Sense Disambiguation (WSD) is the process of identifying the correct sense of the word in the context. In this paper, Naive Bayes supervised classifier has been used to disambiguate words of Punjabi language. The feature extraction process plays a vital role in building the supervised machine learning models.

What is sense inventory?

Abstract. Word Sense Disambiguation (WSD) is the task of associating a word in context with one of its meanings. While many works in the past have focused on raising the state of the art, none has even come close to achieving an F-score in the 80% ballpark when using WordNet as its sense inventory.

Which are the difficulties challenges in word sense disambiguation?

There are significant challenges associated with the informal nature of clinical text, such as typographical errors and incomplete sentences; difficulty with insufficient clinical resources, such as clinical sense inventories; and obstacles with privacy and security for conducting research with clinical text.

Which of the following is approach of WSD?

WSD APPROACHES: There are two approaches that are followed for Word Sense Disambiguation (WSD): Machine-Learning Based approach and Knowledge Based approach. Three types of techniques of machine learning based approaches are: supervised techniques, unsu- pervised techniques, and semi-supervised techniques.

Which technique is used in shallow analysis?

… Shallow NLP conducts partial analysis of a sentence or extracts partial, specific information from a sentence. Deep NLP aims at full-sentence analysis toward capturing the entire meaning of a sentence (Zouaq 2011) . …

Are the Lexemes with the same orthographic form but different meaning?

Homonymy and Types of Homonyms Briefly said homonyms are two or more different lexemes which have the same form but are unrelated in meaning and have different historical sources in language. The words which are homonyms usually have different entries in dictionaries.

What is WordNet in NLP?

WordNet is the lexical database i.e. dictionary for the English language, specifically designed for natural language processing. Synset is a special kind of a simple interface that is present in NLTK to look up words in WordNet. Synset instances are the groupings of synonymous words that express the same concept.
