The process of text tagging can be explained by the following figure:
A document is tokenized and the tokens are passed to the naive tagger. The naive tagger uses a tagging algorithm to find the tags. Then, the geo-coordinate finder identifies the geo-locations (lat-long coordinates) corresponding to those tags. They are then available as the output.
There are various text tagging algorithms, each of which has its own benefits. Let us go through some of the algorithms that can be used for text tagging.
The fuzzy string matching algorithm can be used to match two strings, exactly or partially. This ...
