java.lang.Object

com.bericotech.clavin.resolver.LuceneLocationResolver

All Implemented Interfaces:

LocationResolver

Deprecated.

2.0.0 Use ClavinLocationResolver

@Deprecated
public class LuceneLocationResolver
extends Object
implements LocationResolver

Resolves location names into GeoName objects. Takes location names extracted from unstructured text documents by LocationExtractor and resolves them into the appropriate geographic entities (as intended by the document's author based on context) by finding the best match in a gazetteer.

LuceneLocationResolver

@Deprecated
public LuceneLocationResolver(File indexDir,
                                 int maxHitDepth,
                                 int maxContextWindow)

Deprecated. 2.0.0 Use ClavinLocationResolver

Builds a LuceneLocationResolver by loading a pre-built Lucene index from disk and setting configuration parameters for resolving location names to GeoName objects.

Parameters:

indexDir - Lucene index directory to be loaded

maxHitDepth - number of candidate matches to consider

maxContextWindow - how much context to consider when resolving

Throws:

IOException

org.apache.lucene.queryparser.classic.ParseException

resolveLocations

@Deprecated
public List<ResolvedLocation> resolveLocations(List<LocationOccurrence> locations,
                                                 boolean fuzzy)
                                        throws IOException,
                                               org.apache.lucene.queryparser.classic.ParseException

Deprecated. 2.0.0 Use ClavinLocationResolver.resolveLocations(java.util.List, boolean) or ClavinLocationResolver.resolveLocations(java.util.List, int, int, boolean)

Resolves the supplied list of location names into ResolvedLocations containing GeoName objects. Calls Gazetteer.getClosestLocations(com.bericotech.clavin.gazetteer.query.GazetteerQuery) on each location name to find all possible matches, then uses heuristics to select the best match for each by calling ClavinLocationResolver.pickBestCandidates(java.util.List<java.util.List<com.bericotech.clavin.resolver.ResolvedLocation>>).

Specified by:

resolveLocations in interface LocationResolver

Parameters:

locations - list of location names to be resolved

fuzzy - switch for turning on/off fuzzy matching

Returns:

list of ResolvedLocation objects

Throws:

org.apache.lucene.queryparser.classic.ParseException

IOException
