> Delegate language identification to Tika
> ----------------------------------------
>
> Key: NUTCH-1075
> URL: https://issues.apache.org/jira/browse/NUTCH-1075
> Project: Nutch
> Issue Type: Improvement
> Components: parser
> Affects Versions: 1.4
> Reporter: Julien Nioche
> Assignee: Julien Nioche
> Fix For: 1.4
>
> Attachments: NUTCH-1075.patch
>
>
> In 2.0 the language identification is delegated to Tika and is done as part
> of the parsing step (and not during the indexing as done currently).
> The patch attached is a backport from trunk which implements this and adds a
> new parameter to determine the strategy to use
> {code:xml}
> <property>
> <name>lang.extraction.policy</name>
> <value>detect,identify</value>
> <description>This determines when the plugin uses detection and
> statistical identification mechanisms. The order in which the
> detect and identify are written will determine the extraction
> policy. Default case (detect,identify) means the plugin will
> first try to extract language info from page headers and metadata,
> if this is not successful it will try using tika language
> identification. Possible values are:
> detect
> identify
> detect,identify
> identify,detect
> </description>
> </property>
> {code}
