Examples of Lexicon

com.digitalpebble.classification.Lexicon
A lexicon contains all the information about the tokens used during learning and ensures that the same mapping is used during classification
com.sun.speech.freetts.lexicon.Lexicon
Provides the phone list for words. A Lexicon is composed of three pieces: an addenda, the compiled form, and the letter to sound rules.
- The addenda either contains Word instances that are not in the compiled form, or it contains Word instances that replace definitions in the compiled form. The addenda is meant to be relatively small (e.g., 10's of words).
- The compiled form is meant to hold a large number of words (e.g., 10's of thousands of words) and provide a very efficient means for finding those words.
- The letter to sound rules will attempt to find a definition for a word not found in either the addenda or compiled form.
edu.stanford.nlp.parser.lexparser.Lexicon
An interface for lexicons interfacing to lexparser. Its primary responsibility is to provide a conditional probability P(word|tag), which is fulfilled by the {#score} method. Inside the lexparser, Strings are interned and tags and words are usually represented as integers. @author Galen Andrew

simplenlg.lexicon.Lexicon
This is the generic abstract class for a Lexicon. In simplenlg V4, a Lexicon is a collection of {@link simplenlg.framework.WordElement} objects; it does not do anymorphological processing (as was the case in simplenlg V3). Information about WordElement can be obtained from a database ( {@link simplenlg.lexicon.NIHDBLexicon}) or from an XML file ( {@link simplenlg.lexicon.XMLLexicon}). Simplenlg V4 comes with a default (XML) lexicon, which is retrieved by the getDefaultLexicon method. There are several ways of retrieving words. If in doubt, use lookupWord. More control is available from the getXXXX methods, which allow words to retrieved in several ways
1. baseform and {@link simplenlg.framework.LexicalCategory}; for example "university" and Noun
2. just baseform; for example, "university"
3. ID string (if this is supported by the underlying DB or XML file); for example "E0063257" is the ID for "university" in the NIH Specialist lexicon
4. variant; this looks for a word given a form of the word which may be inflected (eg, "universities") or a spelling variant (eg, "color" for "colour"). Acronyms are not considered to be variants (eg, "UK" and "United Kingdom" are regarded as different words).
  Note: variant lookup is not guaranteed, this is a feature which hopefully will develop over time
5. variant and {@link simplenlg.framework.LexicalCategory}; for example "universities" and Noun
For each type of lookup, there are three methods
- getWords: get all matching {@link simplenlg.framework.WordElement} in the Lexicon. For example,getWords("dog") would return a List of two WordElement, one for the noun "dog" and one for the verb "dog". If there are no matching entries in the lexicon, this method returns an empty collection
- getWord: get a single matching {@link simplenlg.framework.WordElement} in the Lexicon. For example,getWord("dog") would a for either the noun "dog" or the verb "dog" (unpredictable). If there are no matching entries in the lexicon, this method will create a default WordElement based on the information specified.
- hasWord: returns true if the Lexicon contains at least one matching WordElement
