Automatic indexing uses computer programs to examine files and websites for keywords, making it easier to search and classify documents. It is commonly used in search engines, but can have inaccuracies due to poor programming or strange keywords.
Automatic indexing is the act of using a computer program or algorithm to examine files, documents and websites for keywords. This can be used in individual programs, but is also a popular algorithm for search engines, which need to crawl various websites to ascertain their information. An advantage of automatic indexing is that the computer can easily index and search a document much faster than a person can. The downside is that one person has to build the indexer and it is possible for the indexer to miss key points due to incorrect programming.
There are many files found on the internet, computers and storage devices. Each of these documents is usually about a specific topic, and recurring words will reveal the subject of the documents. For example, a medical document will typically use medical terms. An automatic indexing program will examine the document and classify the document based on these words.
Some individual programs, such as document readers, are capable of automatic indexing. When it comes to searching a local network, this feature is usually included with databases which can be difficult to search manually. The most popular place to find automatic indexing is an online search engine, because the search engine has to match the user’s keyword, or search term, with all existing websites. Without this feature, it would be difficult for people to find relevant websites.
The most obvious benefit of automatic indexing is that it takes the work out of humans, who can’t scan a document as fast as a computer. The computer can also classify documents after scanning them, so users don’t have to do this tedious job. While users may need to check the organization for errors, as an indexer can sometimes misplace a document, it’s still easier than doing everything manually.
While there are many benefits, there are also drawbacks to using automatic indexing. As with any program or algorithm, one person must create the program. This means that the programmer has to tell the indexer how to match words, which can lead to inaccuracies resulting from poor programming. The indexer may also be unable to distinguish certain words or may have a large number of inaccuracies due to strange keywords. For example, a medical document discussing the dangers of cosmetics may be misclassified as a beauty and makeup document.
