<div class=Section1>
<p class=MsoNormal>Can anyone confirm my understanding of how DSpace performs keyword
indexing/searching? I suspect that it is doing automatic mapping of singular and
plural forms of words.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>How I came to this understanding was as follows.<o:p></o:p></p>
<p class=MsoNormal>I was searching for an item authored by Alys (alternate
spelling of Alice) Clark.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I retrieved three items none of which had the word alys in the
metadata or bitstream. If I searched for alys on its own I got 168 hits
and a cursory glance at the results list showed that they all had an author
with some part of their name being ali.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I then tried searching for each of the following forms<span
style='font-family:"Arial","sans-serif"'><o:p></o:p></span></p>
<p class=MsoNormal><span style='font-family:"Arial","sans-serif"'>aly, ali,
alis, alys alies <o:p></o:p></span></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>All of these as single search terms retrieved exactly the
same number of records – 168. Results included items with the following
strings in Abstract<o:p></o:p></p>
<p class=MsoNormal><u><span style='font-size:9.5pt;font-family:"Arial Unicode MS","sans-serif";
color:black;background:yellow;mso-highlight:yellow'>- ALIS</span></u><span
style='font-size:9.5pt;font-family:"Arial Unicode MS","sans-serif";color:black'>

system<o:p></o:p></span></p>

color:black'>- Current Trends in Periodontal Diagnosis & Disease
Recognition in Malaysia / T.B. Taiyeb <u><span style='background:yellow;

color:black'>- Radiology in the acute abdomen / P.G. Devitt, A. <u><span
style='background:yellow;mso-highlight:yellow'>Aly</span></u>, M. Thomas<o:p></o:p></span></p>
<p class=MsoNormal><span style='font-size:9.5pt;font-family:"Arial Unicode MS","sans-serif";
color:black'><o:p> </o:p></span></p>
<p class=MsoNormal><span style='font-size:9.5pt;font-family:"Arial Unicode MS","sans-serif";
color:black'>My conclusion is that DSpace is doing some process of mapping
plural to singular forms of words including allowing for alternate endings.
If it is doing this it is very clever but just a little annoying as Alys is not
the plural of Ali.<o:p></o:p></span></p>
<p class=MsoNormal><span style='font-size:9.5pt;font-family:"Arial Unicode MS","sans-serif";
color:black'><o:p> </o:p></span></p>
<p class=MsoNormal><span style='font-size:9.5pt;font-family:"Arial Unicode MS","sans-serif";
color:black'>Also if clever enough to do this why can’t it map fiber to
fibre and color to colour which would have much greater benefits in searching a
database that includes North American and European data.<o:p></o:p></span></p>
<p class=MsoNormal><span style='font-size:9.5pt;font-family:"Arial Unicode MS","sans-serif";
color:black'><o:p> </o:p></span></p>
