<b>Subject:</b> [CWB] Strange issue with character encoding (?) in frequency lists<o:p></o:p></span></p>
<p class="MsoNormal"><o:p> </o:p></p>
<div>
<p class="MsoNormal">I've run into a strange issue that might have to do with character encoding (or it might not). <o:p></o:p></p>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">When I go to Corpus Queries > Frequency lists, select my full corpus, choose to view a list based on lemmas, and then hit Show Frequency List, I get a list of lemmas in which quite a few have phantom accent marks and other diacriticals,
e.g. "sì", "còmo", "èn", "sú", "ïgual", "cúando" (obviously, this is a Spanish corpus).<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">However, when I click on the links for these words and go to the concordance, not a single word has these marks. When I further click through and go to the source texts, the marks also aren't there.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">I've grepped through my tagger's dictionary files (FreeLing), and none of these forms exist as lemmas or lexemes. I've also grepped through the *.vrt files that the corpus was compiled from, and none of these forms are present.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">I've run into an additional strange issue that is probably related. When I make a subcorpus that is an exact copy of the source corpus, the same problem occurs,but most of the spurious accents and such are
<u>different</u> (e.g. "qúe", "nó", "á", "sì", "én"). <o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">I'm attaching an edited screenshot that shows the top of the frequency list based on the full corpus on the left and the subcorpus that contains the full corpus on the right, with errors in red boxes. <o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<div>
<p class="MsoNormal"><img width="174" height="502" style="width:1.8083in;height:5.2333in" id="_x0000_i1025" src="cid:image001.png@01D5132E.F1ED9400" alt="Lemmas.png"><o:p></o:p></p>
</div>
</div>
<div>
<p class="MsoNormal">Of course, in some cases both of the highlighted forms exist in Spanish (e.g. #28, "mi" and "mí"), but in spite of being different they have the same frequencies in the corpus and the subcorpus, which further suggests that it's not the
underlying data that's causing this.<o:p></o:p></p>
