Puzzling XQuery result
by Meredith Gregory 09 Apr '11

09 Apr '11

Dear BaseXers, i've got a result from an XQuery that i don't understand and am looking for insight and guidance. i've got a collection called 'Squibble' with three documents in it. They are listed below. The query for $rcrd in collection( 'Squibble' )//record where $rcrd/*[1] = <contentChannel><String>email</String></contentChannel> return $rcrd returns record elements from the first *two* documents. This is surprising to me because the first child of the first record element in the first document is <contactMeUsing>...</contactMeUsing>, not <contentChannel>...</contentChannel>. i was expecting it to return just the record element from the second document. i confess, i don't know anything about XQuery. So, it could be that i don't understand how the where clause is supposed to work. Any clues would be most appreciated. i'm running my tests using - BaseX 6.6 - on Mac OS X 10.6.7 Best wishes, --greg <?xml version="1.0" encoding="UTF-8"?> <record> <contactMeUsing> <String>email</String> </contactMeUsing> <String>{&quot;com.biosimilarity.lift.model.store.MonadicTermTypes_-Ground&quot;:{&quot;v&quot;:{&quot;@class&quot;:&quot;string&quot;,&quot;$&quot;:&quot;for the win Mikail.Mauz(a)gmail.com &quot;},&quot;_-outer&quot;:{&quot;@class &quot;:&quot;com.biosimilarity.lift.model.store.PersistedMonadicTS$TheMTT$&quot;}}}</String> </record> <?xml version="1.0" encoding="UTF-8"?> <record> <contentChannel> <String>email</String> </contentChannel> <String>{&quot;com.biosimilarity.lift.model.store.MonadicTermTypes_-Ground&quot;:{&quot;v&quot;:{&quot;@class&quot;:&quot;string&quot;,&quot;$&quot;:&quot;for the get Donald.Duque(a)yahoo.com &quot;},&quot;_-outer&quot;:{&quot;@class &quot;:&quot;com.biosimilarity.lift.model.store.PersistedMonadicTS$TheMTT$&quot;}}}</String> </record> <?xml version="1.0" encoding="UTF-8"?> <record> <phone> <var>cell</var> </phone> <String>{&quot;com.biosimilarity.lift.model.store.MonadicTermTypes_-Ground&quot;:{&quot;v&quot;:{&quot;@class &quot;:&quot;string&quot;,&quot;$&quot;:&quot;2xx.6xx.3xxx&quot;},&quot;_-outer&quot;:{&quot;@class &quot;:&quot;com.biosimilarity.lift.model.store.PersistedMonadicTS$TheMTT$&quot;}}}</String> </record> -- L.G.

tf/idf
by Wiard Vasen 06 Apr '11

06 Apr '11

Dear sirs of Basex, I am doing my Master thesis on the letters of Vincent van Gogh at the University of Amsterdam. For that purpose I use BaseX to analyze the letters. I wonder, is there the possibility to generate a tf/idf score automatically? In your faq I noticed there needs to be a special term like 'SET SCORING 0' to be able to get a tf/idf score. This information I get from the following page: http://docs.basex.org/wiki/Full-Text Could you help me with this? I would be very grateful. Kind regards,

Hi, Does Basex have trigger? If not, can you please show me how to recognize which documents are changed after the execution of an xquery update? Thanks. Cheers, An

Re: [basex-talk] Updates and indexing

Hi, Just wondering if there is something available to test from the index update effort. Thanks, Gary From: basex-talk-bounces(a)mailman.uni-konstanz.de [mailto:basex-talk-bounces@mailman.uni-konstanz.de] On Behalf Of Gary Larsen Sent: Tuesday, March 15, 2011 3:09 PM To: basex-talk(a)mailman.uni-konstanz.de Subject: Re: [basex-talk] Updates and indexing Hi Dimitar, Thanks for the info. I see that adding a document changes the database indexing status to off. A query to locate a document by node value in a database with 54k documents went from 3 seconds to 4 minutes. I can image its difficult to balance performance in different aspects of the application and maintain database stability at the same time. For the past couple of weeks Ive tested query performance on a half dozen databases and BaseX queries were almost always quickest and never crashed even when running with lower memory. Depending on how things go with my research I may be able to help test the index updating feature when you are ready for that. Thanks, Gary >Hi Gary, >I'm the one who's working on the index updating.

using variables along with namespace prefix
by Sony Vijay 05 Apr '11

05 Apr '11

Hi, I am using the sample xml document(xyz) shown below: <entry xmlns:libx="http://libx.org/xml/libx2"> <libx:libapp> First libapp </libx:libapp> <libx:libapp> Second libapp </libx:libapp> </entry> I am using BaseX 6.5.2 and am trying to use a variable along with a namespace prefix in my sample xquery like so: declare variable $libx_ns as xs:string external; declare namespace libx=$libx_ns; let $type := 'libapp' return doc('xyz')/entry*[libx:{$type}]*[1] When I pass the value "http://libx.org/xml/libx2" to the parameter libx_ns and run the above xquery I see the following exception: [XPST0003] Incomplete expression. However, the following xquery works: declare variable $libx_ns as xs:string external; declare namespace libx=$libx_ns; let $type := 'libapp' return doc('xyz')/entry*[libx:libapp]*[1] The child nodes could be libx:libapp or libx:module etc. So, I will have to use a variable rather than hard wiring the actual child name. But, I am not sure how to use a variable along with a namespace prefix. Am I doing something wrong or is this a bug ? Thanks, Sony

You can change the input type in the left combobox to XQuery and then enter your full text query. However, I would suggest to use the XQuery view, because it offers detailed error feedback and syntax highlighting. -- Andreas Am 02.04.2011 um 18:01 schrieb Wiard Vasen: > Thanks a lot Andreas for your answer on my question. > I will look at your solution this week. > > I was in Berlin this weekend. > > Is it possible to use set scoring * and then enter full text queries in the upper text-bar? > > Thank you for the live-demo as well. > > If I succeed I come back to you. > > Regards, > > Wiard Vasen > > Vrije Universiteit van Amsterdam > Masterthesis: Deep diving into Van Gogh > > 2011/3/31 Andreas Weiler <andreas.weiler(a)uni-konstanz.de> > Dear Wiard Vasen, > > you just need to set the scoring property once. > If you work in the GUI: > > Go to the top input bar, choose command and type: > > set scoring * > > as * set the scoring algorithm you like. > > In the console just type: set scoring * > > After setting this you can use the score function, like in the 8th query of our online demo (basex.org/products/live-demo) > > let $names := ('Jack London', 'Jack', 'Jim Beam', 'Jack Daniels') > for $name at $pos score $score in $names[. contains text 'Jack'] > order by $score descending > return <name pos='{ $pos }'>{ $name }</name> > > Don't hesitate to ask for more, > Andreas > > Am 30.03.2011 um 22:02 schrieb Wiard Vasen: > >> Dear sirs of Basex, >> >> I am doing my Master thesis on the letters of Vincent van Gogh at the University of Amsterdam. >> For that purpose I use BaseX to analyze the letters. >> >> I wonder, is there the possibility to generate a tf/idf score automatically? >> In your faq I noticed there needs to be a special term like 'SET SCORING 0' to be able to get a tf/idf score. >> >> This information I get from the following page: http://docs.basex.org/wiki/Full-Text >> >> Could you help me with this? >> >> I would be very grateful. >> >> Kind regards, >> _______________________________________________ >> BaseX-Talk mailing list >> BaseX-Talk(a)mailman.uni-konstanz.de >> https://mailman.uni-konstanz.de/mailman/listinfo/basex-talk > >

Dear all, thanks to everyone who gave us great feedback on BaseX 6.6, either by e-mail or directly at the XMLPrague conference! This way, we were able to finish Version 6.6.1 just one week later, which offers some exciting performance improvements and some more bug fixes: XQuery: [ADD] index rewritings added for .../text()[. = ..] syntax [ADD] optimizations of mixed axis path expressions, e.g.: //x/name() [MOD] index rewritings on collections fixed and generalized [MOD] faster evaluation of filters with pos. predicates, e.g.: $x[5] [FIX] fixed relocation of let clauses in GFLWOR expressions [FIX] trace function returned wrong original results [FIX] variables in catch clauses were discarded [FIX] HOF optimizations and fixes GUI: [FIX] language option (for Japanese, German, etc. interface) fixed To be continued, Christian BaseX Team, 2011
