> Add Lookup Cache to EntityLinking Engine
> ----------------------------------------
>
> Key: STANBOL-1230
> URL: https://issues.apache.org/jira/browse/STANBOL-1230
> Project: Stanbol
> Issue Type: Improvement
> Components: Enhancement Engines
> Affects Versions: 0.12.0
> Reporter: Rupert Westenthaler
> Assignee: Rupert Westenthaler
> Fix For: 0.12.0
>
>
> The EntityLinkingEngine should cache results of lookups on the
> EntitySearchers.
> Entities are often reoccurring in analyzed Documents. Because of that caching
> results for look upped tokens should provide considerable performance
> improvements as tatistics shows that ~90% of the processing time for the
> EntityLinking engine is contributed by the entity look-up.
> So if 20% of all Entity mentions are about reoccurring Entities the
> processing time should be reduced by about 18%.
> The cache will use the list of search string as key and a list of returned
> Entities as value. The cache will only collect look-up results for the
> currently analyzed document.
> EntityLinking statistics will be updated to include the cache hit percentage.
> This issue affects both the trunk (1.0.0-SNAPSHOT) as well as the stable 0.12
> releasing branch.
