Machine tags, also known as triple tags, provide more precision in coding and searching for web developers and software programmers. They are useful for geotagging and allow users to retrieve items without tag data. Tags are metadata that make items easier to find and can be used on text, images, bookmarks, and files. Tag clouds provide a visual means for users to see popular terms. Different websites use unique tagging methods, such as geotagging and hash tags on Twitter.
In computers, a machine tag is also called a triple tag. Web developers and software programmers sometimes use triple tags to give their users more precision in coding and searching. Using a machine tag gives more power to the user in terms of retrieving items, especially if those items don’t contain the tag data itself like in photos and images. The machine tag can also be useful in the emerging tagging practice called geotagging. Geotagging is the method used to place geographic identification, such as latitude and altitude, on photographs, websites or videos.
Several websites help site visitors navigate their pages by allowing users to tag their content. Some websites implement the use of a machine tag to allow their users to have more accuracy in coding. A car tag uses a special syntax to provide more information about an existing tag. The syntax of a machine tag involves a value, a predicate, and a namespace. A namespace describes which classification a tag is included in, the predicate describes the property of the namespace, while the value contains any character usually enclosed in quotes.
The term tag in computer systems and Internet terminology refers to a keyword attached to or assigned to a group of related data or information. It can be used on blocks of text, digital images, Internet bookmarks and computer files. Tags are descriptive of items that may or may not be visible to users. In this way, tags are considered metadata. They are something that is not necessary to be viewable by people browsing websites or people using computer files, but they are extremely useful for machines and search engines.
Labeling items with a tag makes them easier to find when people search for them using search engines or the search features built into websites or operating systems. Searching for a particular item can also be facilitated by the presence of tag clouds on web pages. Tag clouds provide a visual means for users to see which terms are the most popular and which terms are not typically searched for by users. A tag is usually chosen informally by people uploading or posting information.
Other websites use other forms of tagging that cater to the specific and unique needs of their visitors. Websites that use geotagging such as Flickr use automatic tags to add geographic location information to photos. Twitter uses hash tags to describe the information contained in a tweet. Hash tags are kept compact to fit Twitter’s character limit, which is 140 characters. Whatever form tagging takes, it gives users the flexibility to search and describe their data for their own convenience and that of other people as well.
