A synonym dictionary is a type of lexical resource that provides a list of words and phrases that have the same or similar meaning. They are often used in text analytics to improve the accuracy of language processing algorithms.
When used in the context of enterprise search, a synonym dictionary is a file that contains a list of words and their synonyms. This file is used by the search engine to expand user queries and improve search accuracy.
The format of a synonym dictionary file is relatively simple. Each line in the file represents a single word or phrase and its synonyms. The words are separated by commas, and each synonym is enclosed in quotation marks. For example, the following line from a synonym dictionary file represents the word “car” and its three synonyms:
“car”, “automobile”, “vehicle”
Enterprise search engines typically come with a default synonym dictionary, but this file can be customized to the specific needs of an organization. Custom synonym dictionaries are often used to account for industry-specific terminology, abbreviations, and nicknames.
When adding custom entries to a synonym dictionary, it is important to consider the different ways that users might search for the same thing. For example, someone looking for information about “cars” might also search for “automobiles” or “vehicles”. But they might also search for “trucks”, “SUVs”, or “sedans”. As such, it is important to include as many relevant synonyms as possible in the synonym dictionary file.

They are often used in text analytics to improve the accuracy of language processing algorithms. Synonym dictionaries can be general or specific, depending on the needs of the application.
