Rupert Westenthaler updated STANBOL-1049:
-----------------------------------------
Description:
This issue will allow the EntityLinkingEngine to use upper case token
information for linking of languages without NLP support.
If TextProcessingConfig#LinkUpperCaseTokens is enabled only upper case tokens
that are equals or longer than the configured min search token length will be
linked with the controlled vocabulary. Lower case Tokens equals or longer than
the min search token length will be used for matching.
Deactivating TextProcessingConfig#LinkUpperCaseTokens will preserve the current
behavior where all Tokens with equals or more chars as the configured min
search token length will be linked.
NOTE: that this will require to explicitly configure
{lang};uc=MATCH
for languages that do not upper case characters (e.g. Arabic)
---
Definitions:
-------
The EntityLinking Engine distinguishes three (Token Types)[1]:
* Linkable Token: A Word that triggers a lookup in the Controlled Vocabulary
* Matchable Token: A Word that is used to search and match Entities, but does
not trigger an lookup
* Other Tokens: Not used for search and matching. Might be used for fine tuning
confidence values.
Language level information incude
* isUnicaseScript [true, false]: If the processed language uses a unicase
script - does not know upper case letters
Token level information include
* hasLinkablePos [true,null,flase]: If a POS tag matches the linkable POS
* hasMatchablePos [true,null,false]: If a POS tag matches the processable POS
* isUpperCase [true,false]: If the first letter is an upper case one
* hasAlphaNumeric [true,false]: if the word has an alpha numeric char
* hasSearchableLength [true,false]: if the word is longer as the configured
"Min Search Token Length"
* isSubSentenceStart [true, false]: If the POS tag of an Token is Pos#Quote.
Algorithm:
------
This describes the algorithm used to classify Tokens as linkable, matchable and
other based on the above properties. Rules are applied in the given order. A
summary of the result for Tokens with no POS tags is given in the next section
__(1) Basic rules:__
* all Tokens without an AlphaNumeric character are not linkage and matchable
* all tokens with hasLinkablePos are linkable
* all linkable tokens and tokens with matchable POS matchable
__(2) Unknown POS tag Rules
This rules only apply to Tokens with AlphaNumeric characters that are not (yet)
marked as linkable
* if the processed language uses a unicase script or
* all tokens equals or longer than
__(2) Uppercase Rules__
This rules are applied to all none linkable token that are (1) upper case and
(2) not at a sentence or subSentence start
* if TextProcessingConfig#LinkUpperCaseTokens is enabled
* all matchable Tokens are also linkable
* all other Tokens are converted to matchable
* if TextProcessingConfig#MatchUpperCaseTokens is enable
* all other Tokens are converted to matchable
* all Tokens with linkablePos == null and searchableLength are converted to
linkable
__(3) Searchable Token Rules__
This rules are only applied to not linkable Tokens with hasLinkablePos == null
and hasMatchablePos == null
* if TextProcessingConfig#LinkUpperCaseTokens == false
* all Tokens with searchableLength are marked as linkable
Languages without NLP support
-----
The above algorithm ensures that for languages without NLP support (no POS
tags) Tokens are marked as follows:
__ LinkUpperCaseTokens is enabled __
* Linkable: All upper case tokens with a searchable length
* Matchable: All upper case tokens shorter as the min searchable length; All
lower case tokens with a searchable length
* Other Tokens: All lower case tokens shorter as the min searchable length
__ LinkUpperCaseTokens is disabled __
* Linkable: All tokens with a searchable length
* Other Tokens: All tokens shorter as the min searchable length
