> ##Description
> This program aims to provide the support to identify geonames for any
> unstructured text data in the project NSF polar research.
> https://github.com/NSF-Polar-Cyberinfrastructure/datavis-hackathon/issues/1
> This project is a content-based geotagging solution, made of a variaty of NLP
> tools and could be used for any geotagging purposes.
> ##Workingflow
> 1. Plain text input is passed to geoparser
> 2. Location names are extracted from the text using OpenNLP NER
> 3. Provide two roles:
> * The most frequent location name choosed as the best match for the
> input text
> * Other extracted locations are treated as alternatives (equal)
> 4. location extracted above, search the best GeoName object and return the
> resloved objects with fields (name in gazetteer, longitude, latitude)
> ##How to Use
> *Cautions*: This program requires at least 1.2 GB disk space for building
> Lucene Index
> ```Java
> function A(stream){
> Metadata metadata = new Metadata();
> ParseContext context=new ParseContext();
> GeoParserConfig config= new GeoParserConfig();
> config.setGazetterPath(gazetteerPath);
> config.setNERModelPath(nerPath);
> context.set(GeoParserConfig.class, config);
>
> geoparser.parse(
> stream,
> new BodyContentHandler(),
> metadata,
> context);
>
> for(String name: metadata.names()){
> String value=metadata.get(name);
> System.out.println(name +" " + value);
> }
> }
> ```
> This parser generates useful geographical information to Tika's Metadata
> Object.
> Fields for best matched location:
> ```
> Geographic_NAME
> Geographic_LONGTITUDE
> Geographic_LATITUDE
> ```
> Fields for alternatives:
> ```
> Geographic_NAME1
> Geographic_LONGTITUDE1
> Geographic_LATITUDE1
> Geographic_NAME2
> Geographic_LONGTITUDE2
> Geographic_LATITUDE2
> ...
> ```
