Related keywords like surf, surfing and surfers all have “surf†as the stem (base). Few SEs use stemming to provide results from all the related terms for an entered search terms.
a process of suffix stripping that aims to reduce words to a shorter form which is closer to the linguistic root. Usually stemming is carried out by a stemming algorithm, such as that developed by Lovins or Porter.
Using the stem or root of a word to produce a variety of relevant results. For example, stemming on a search for ″hiking″ would produce search results containing hike, hiker, hikes, hiking, hiked , et cetera.
expansion of searches to include plural forms and other word variations.
The inclusion of word variations and plurals of a term. A search can include allwords that come from the same "stem" word. Examples: act acts, acting, actor
The family of words that derive from the same base (radical). Word stemming is a common way of generating new keywords.
Finding a word's root and using the root as a search term is called "stemming." Stemming allows you to enter "automotive" and get back results containing the terms "truck," "car," and "auto."
Variations of words. For example, if I entered the query 'walk', a Search Engine that supports stemming might return results that include 'walking' or 'walks'.
Some databases automatically search for all of the words that come from the same "stem" word (also called "root" word) unless you indicate that you only want the word you entered. An example would be if you entered computer, the database would also search for computing, computers, computation, etc. Stop Words: Stop words are small, frequently occurring words that are often ignored when typed into a database or search engine search. Some examples: THE, AN, A, OF. If a stop word is typed at the beginning of a title search, this will often stop the search entirely.
A method of mapping a linguistic stem to all matching words. For example, in English, the stem "buy" matches "bought," "buying," and "buys."
Variations of a root word. For example, using the query 'write', stemming might also result in returns for 'writing' and 'writes.' Stop Word A stop word is a common word that is ignored by search engines because it does not add to relevancy. Words such as 'the', 'it', 'a', and 'for' are considered stop words are ignored by many search engines. Submission Service Services that submit your website to search engines for inclusion are referred to as submission services. These can be either automated programs or manual hand submission. This is un-needed if your site is properly optimized.
Word variations. For example, if I entered the query "run", a search engine that supports stemming might return results that include "running" or "runs".
The way the search engine use to add variations to the endings of search words or phrases so there will be more hits.
The use of a stem [i.e. root] of a word to search words that are derived from it. For example, "child" would retrieve information on child, children, childhood, childless and so on.
Some search engines will use your search term as the stem of a related word, for example, you search for a singular term and the search engine includes the plural form in the results. Sometimes, exceptions are made, for example, blind/blinds are not usually related terms.
Word variations. For example, if I entered the query "swim", a search engine that supports stemming might return results that include "swimming" or "swims".
The ability of search engines to associate words with prefixes and suffixes to their word stem. If you have "water" on your website, the search engines with this ability will also associate "watering" and "watered" with your page.
In natural spoken language, expressions are used in various word forms, depending on their use in the grammatical constructions. In order to ensure that as much relevant information as possible is found, words have to be normalised so that words that are not given in exactly the same form will still be returned as hits after matching with search terms.
The use of linguistic analysis to get to the root form of a word. Search engines that use stemming compare the root forms of the search terms to the documents in its database . For example, if the user enters "viewer" as the query , the search engine reduces the word to its root ("view") and returns all documents containing the root - like documents containing view, viewer, viewing, preview, review etc.
removing (usually automatically) the ending of a word, typically with a fast algorithm, to form a canonical representation that usually approximates the root form
In keyword searching, word endings are automatically removed (lines becomes line); searches are performed on the stem + common endings (line or lines retrieves line, lines, line's, lines', lining, lined). Not very common as a practice, and not always disclosed. Can usually be avoided by placing a term in " ". (4/99)
For example, the word optimization has the stems of optimized, optimize, and so on.
The ability for a search to include the "stem" of words. For example, stemming allows a user to enter "swimming" and get back results also for the stem word "swim."
Some engines and directories return results based on the same stem as the keyword entered as a search term.(For example, a search on the word "share" would yield results with that included words such as sharing, shares, shared).
Refers to root word origins. For example, Search, Searching, and Searches all have Search as the root stem. Some search engines use stemming to provide results from more than just the entered search terms. A search on Boat could return results on Boating or Boats.
Stemming is the ability for a search engine to search for variations of a word based on its root. For example, if the word “running” is typed into a search query, search engines that utilize stemming might also display documents that contain the word "run."
The principle of reducing variations of the same word to the stem of that word.
the action performed by a search engine where it takes the stem of a keyword and delivers similar results. For example, a keyword "run" may return results for "running" or "runner".
In informational retrieval, reduction of morphological variants of a word to a common stem.
An advanced Search feature that allows you to search for all variants of your search terms. For example, a search for the word run will retrieve web pages that contain any of the words run, running, runner, etc., when word stemming is turned on.
A function of some search engines and directories which allows results to be returned from some or all keywords based on the same stem as the keyword entered as a search term. For example, when stemming is switched on, a search for the word dance will return matches for any word whose stem is danc-, matching the keywords dance, dancer and dancing.
Stemming is the process for reducing inflected (or sometimes derived) words to their stem, base or root form — generally a written word form. The stem need not be identical to the morphological root of the word; it is usually sufficient that related words map to the same stem, even if this stem is not in itself a valid root. The algorithm has been a long-standing problem in computer science; the first paper on the subject was published in 1968.
