Solrians, We have a request to drop phonetic strings from xlsx as the default in Tika. I'm not familiar enough with Japanese to know if users would generally expect to be able to search on these as well as the original. The current practice is to include them. Any recommendations? Thank you!

Takahiro Ochi created TIKA-2440: ----------------------------------- Summary: Phonetic strings handling for multilingual environments. Key: TIKA-2440 URL: https://issues.apache.org/jira/browse/TIKA-2440 Project: Tika Issue Type: Improvement Components: parser Reporter: Takahiro Ochi Priority: Minor Hi there, I would like to propose an idea to improve phonetic strings handling for multilingual environments. I believe Tika should not concatenate phonetic strings because text with phonetic strings is recognized as noisy text in most situations of natural language processing. Excel files include phonetic strings in some languages such as Japanese, Chinese and so on. Apache POI concatenates phonetic strings onto the shared strings when Tika extract text from Excel files. Recent Apache POI has an switch flag for phonetic strings concatination as follows: https://poi.apache.org/apidocs/org/apache/poi/xssf/eventusermodel/ReadOnlySharedStringsTable.html#ReadOnlySharedStringsTable(org.apache.poi.openxml4j.opc.OPCPackage,%20boolean) Tika should set the 2nd argument "includePhoneticRuns" as false. Here is the simple patch for my idea. {code:java} $ diff -ru XSSFExcelExtractorDecorator.java ./tika/tika-1.15/tika-parsers/src/main/java/org/apache/tika/parser/microsoft/ooxml/XSSFExcelExtractorDecorator.java --- XSSFExcelExtractorDecorator.java 2017-06-10 19:13:33.355412625 +0900 +++ ./tika/tika-1.15/tika-parsers/src/main/java/org/apache/tika/parser/microsoft/ooxml/XSSFExcelExtractorDecorator.java 2017-06-10 19:14:30.452411830 +0900 @@ -130,7 +130,7 @@ styles = xssfReader.getStylesTable(); iter = (XSSFReader.SheetIterator) xssfReader.getSheetsData(); - strings = new ReadOnlySharedStringsTable(container); + strings = new ReadOnlySharedStringsTable(container,false); } catch (InvalidFormatException e) { throw new XmlException(e); } catch (OpenXML4JException oe) { {code} -- This message was sent by Atlassian JIRA (v6.4.14#64029)
