Subject [jira] [Commented] (TIKA-2038) A more accurate facility for detecting Charset Encoding of HTML documents
Date Mon, 01 Aug 2016 11:15:20 GMT

    [ https://issues.apache.org/jira/browse/TIKA-2038?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15401867#comment-15401867

Tim Allison commented on TIKA-2038:
-----------------------------------

bq. Unfortunately, I didn’t compare the results of my algorithm against the charsets in
meta tags. 
Wait, as I reread your paper, you did do this in the second half of the paper on the language-focused
corpus.  Further, below, you state that nearly all of the pages in the first corpus had meta-headers
but that you had turned off the metaheader detection for the first corpus.  If you had turned
it off, why wouldn't you have used it as ground truth for mozilla+icu4j as you did in the
second part of the paper?

> Currently, Tika uses icu4j for detecting charset encoding of HTML documents as well as
the other naturally text documents. But the accuracy of encoding detector tools, including
icu4j, in dealing with the HTML documents is meaningfully less than from which the other text
documents. Hence, in our project I developed a library that works pretty well for HTML documents,
which is available here: https://github.com/shabanali-faghani/IUST-HTMLCharDet
> Since Tika is widely used with and within some of other Apache stuffs such as Nutch,
Lucene, Solr, etc. and these projects are strongly in connection with the HTML documents,
it seems that having such an facility in Tika also will help them to become more accurate.
