Regarding relevancy ranking

This is regarding relevancy ranking. During migration from 2.1.1 to 11 the relevancy of products are different though the configuration is same.
So I am trying to find which ranking module is affecting this. While testing this, I am seeing strange behavior.
One v11.0, I see that NUMFIELDS module is giving two different relrank scores for a record in two different but similar queries.
In one query, I am allowing relrank modules to be chosen as it is configured in recsearch_config.xml and in other query I am specifying Nrr parameter, with same relrank modules.
Here are the log lines from Dgraph log
Query without Nrr
Nty=1&Ntx=mode+matchall&Ntk=primary&Nx=whyrank&N=0&Ntt=book%20tape
Query with Nrr
Nrr=nterms,maxfield,numfields&Nrk=primary&Nrt=book%20tape&N=0&Ntk=primary&Ntt=book%20tape&Nty=1&Ntx=mode+matchall&Nx=whyrank
Result for the Query without Nrr
DGraph.WhyRank:
[ { "nterms" : { "evaluationTime" : "0.001220703125", "stratumRank" : "100", "stratumDesc" : "Matched 2 of 2 terms" }}, { "maxfield" : { "evaluationTime" : "0.001220703125", "stratumRank" : "26", "stratumDesc" : "field match", "rankedField" : "p_name_pr" }}, { "numfields" : { "evaluationTime" : "0.001220703125", "stratumRank" : "1", "stratumDesc" : "Matched 1 of 54 fields", "fieldsMatched" : ["p_highsm_stmt"] }} ]
DGraph.WhyDidItMatch:
p_highsm_stmt: Was Gaylord® Bookcraft® 6 mil Paper Write-On Book Tape
Result for the Query with Nrr
DGraph.WhyRank:
[ { "nterms" : { "evaluationTime" : "0.001708984375", "stratumRank" : "100", "stratumDesc" : "Matched 2 of 2 terms" }}, { "maxfield" : { "evaluationTime" : "0.001708984375", "stratumRank" : "26", "stratumDesc" : "field match", "rankedField" : "p_name_pr" }}, { "numfields" : { "evaluationTime" : "0.00244140625", "stratumRank" : "4", "stratumDesc" : "Matched 4 of 54 fields", "fieldsMatched" : ["Category", "p_highsm_stmt", "p_mfg_sku_pr", "p_name_pr"] }} ]
DGraph.WhyDidItMatch:
p_highsm_stmt: Was Gaylord® Bookcraft® 6 mil Paper Write-On Book Tape
You can see that it says 4 fields matched in one results and 1 field matched in another results.
Cross field is enabled for the search interface.
Does anybody know what's happening here. I would like to get the results as they come in "With Nrr" query for "Without Nrr" case too.

Hello!
   We replaced --stat-brel with the following URL parameters to enable "whyrank" properties on the results (you can see them in a JSP reference app automatically when enabled):
   Why Rank is enabled per-query by using the existing Dx parameter (Dx=whyrank), or the new Nx parameter (Nx=whyrank) in the URL.
   Results are returned in a new Dgraph.WhyRank property.
   They provide a little bit more info than the old --stat-brel flag.

Relevance ranking, how?

Hi,
I am newbi in Oracle Text and I need help.
Is there any one who can tell me how to use the Relevance Ranking in Oracle Text?
best regards
Nasser

You can use the static module in the rel rank or if you wish to stratify to boost certain records to appear at the top of your search results then you can use this approach with your current rel rank search interface. This is an example using the wine demo with cross field matching enabled on the search interface All
In order for the query * portion to respect you current rel rank you will need to construct a Ntx query like so and not use Ns.
&Ntx=mode+matchallpartial+rel+stratify(collection()/record[P_WineID="89955"],collection()/record[P_WineID="73036"],*),All

Relevance Ranking Documenation

Anyone know where I can find information detailing how TREX assigns relevance to documents?

Hi Eric
Even though there is no detailed information on how TREX assigns relevance to documents, you could take a look at this thread: TREX Algorithms For Relevance Ranking of Results
I believe that could enlighten you a bit.
Kind regards,

Configuring relevance ranking evaluator 2.1.2 to MDEX engine 6.4.0

Hi CAN some body explain me why is this occuring when i am trying to configure relevance ranking evaluator to my current endeca work bench
Unable to query the MDEX Engine.
Specified MDEX Engine is:
Host: localhost
Port 15000
MDEX Engine query failed: make sure that an MDEX Engine is listening on the configured host and port. Verify that you're using the appropriate API version for your Endeca installation. The jar files in WEB-INF/lib should match those of the MDEX Engine version.
If you would like to connect to a different MDEX Engine, click the "Change MDEX Engine" button above.

Hi Praveen,
Follow below steps to configure:
1. Copy rel rank evaluator in
<Endeca>/PlatformServices/6.1.3/tools/server/webapps (You can keep it any where on disk but provide correct path in relrankEvaluator.xml)
2. Update path in relrankEvaluator.xml accordingly.
3. Copy relrankEvaluator.xml to
<Endeca>/PlatformServices/workspace/conf/Standalone/localhost (you can copy this to <Endeca>/ToolsAndFrameworks/3.1.2/server/workspace/conf/Standalone/localhost mostly preferred approach)
4. Copy updated endeca libs from jspref application to relrankEvaluator lib dir
5. Restart platform services (or EndecaToolsService if you have copied/configured relrankEvaluator.xml with TF)
6. Try to access the URL,
http://<host name>:8888/relrankEvaluator/index.jsp (or http://<host name>:8006/relrankEvaluator/index.jsp if configured with TF)
If issue still persist click on change MDEX engine, enter <host name>, <port> and click ok on config box. This should work

IFCORE-1565: The Dgraph could fail when using a relevance ranking strategy.

Hi,
I just saw the release notes for Endeca 6.2.2 and read this bug:
IFCORE-1565: The Dgraph could fail when using a relevance ranking strategy.
Is there someone who could provide some more information on this bug? What is it and when does it occur? Reading the word 'could' would suggest a kind of unpredictability?
Thanks,
Maarten

The known trigger for the bug was doing relrank on a query that contained multiple text searches.

Relevance Ranking Module

Is the Relevance Ranking Evaluator Module in Workbench available for Oracle Tools Framework 3.1?

Hi. Yes, it's available as a Workbench Extension and is still a separate package (for now). The previous version works with 3.1, so it's still:
Oracle Endeca Relrank evaluator 2.1.2 for Generic Platform

Maxfield relevance algorithm ranking dimensions higher than properties

We are using MaxField as one of the relevance algorithm in our search interfaces and observed that dimensions with low rank is matched first than compared to property of higher rank.
Records that match with dimensions are ranked in the results though their "relevance_rank" is lower than property. But the endeca documentation explains that records will be ranked based on "relevance rank" and doesnt treat dimension and property with differnce.
Here's the example
+<SEARCH_INTERFACE CROSS_FIELD_BOUNDARY="ALWAYS" CROSS_FIELD_RELEVANCE_RANK="0" DEFAULT_RELRANK_STRATEGY="All" NAME="All">+
+     <MEMBER_NAME RELEVANCE_RANK="77">D_Type</MEMBER_NAME>+
+     ....+
+     ...+
+     <MEMBER_NAME RELEVANCE_RANK="50">P_Type</MEMBER_NAME>+
+     .....+
+     .....+
+     <MEMBER_NAME RELEVANCE_RANK="64">D_Category</MEMBER_NAME>+
+     ......+
+     ......+
+     <MEMBER_NAME RELEVANCE_RANK="1">P_Name</MEMBER_NAME>+
+</SEARCH_INTERFACE >+
The records that match for D_category are given higher rank, though it matches for the property "P_Name".
Need some validattion here, if our understanding is correct.
-M

Muthu,
Still records matching D_Category where retrieved first compared to P_Name. Currenlty have modified this search interface to include only "MaxFiled". Are you setting the Relevancy Rank module via a URL query
EXAMPLE
controller.jsp??N=0&Ntk=P_Desc&Ntt=sonoma&Nrk=All&Nrt=pear&Nrr=field&Nrm=matchall
Or via a relrank_strategies.xml. If the later have a look at your ./{APP_DIR}/data/forge_output/ directory and verify if the {app_prefix}.recsearch_config.xml contains the order you expected. If ./{APP_DIR}/data/forge_output/ does -not- include your changes, you may be using the Forge Configuration Manager (FCM), the hyEnd integration with hybris, or another customization that updates ./{APP_DIR}/data/processing and is overriding your changes.
In the example of the hyEnd integration, if the changes -can- be found in ./{APP_DIR}/data/complete_index_config you can copy your changes after ConfigurationGeneratorForge has run but before Forge runs
EXAMPLE
<script id="BaselineUpdate">
<bean-shell-script>
<![CDATA[
          // Generate instance configuration
         ConfigurationGeneratorForge.archiveLogDir();
         ConfigurationGeneratorForge.run();
          cp("/app/dir/apps/MuthuTest/data/complete_index_config/recsearch_config.xml.xml","/app/dir/apps/MuthuTest/data/processing/MuthuTest.recsearch_config.xml");
         // archive logs and run ITL
         Forge.archiveLogDir();
         Forge.run();
         Dgidx.archiveLogDir();

Endeca Relvance Ranking on Workbench - not working

Hi,
I have installed the Workbench, Platform service, Endeca Server 7.4 and now installing and deploying Relevance Ranking module. I have have followed all steps as provided in the document. ONce I open the workbench, I am able to see the Relevance application but when I open it it gives me following error. :
HTTP Status 404 -

I am also not able to see the image which I specified in the ws-extensions.xml
Any verification step or any correction then do let me know. I am trying to do relevance ranking on dataset in MDEX on urgent basis.
Thanks and Regards,
Ashwani

The Oracle Endeca Information Discovery product ships with a different version of the Endeca Server (aka. MDEX engine). It boasts a web service API whereas the Oracle Endeca Guided Search product still uses the Java API which the relevancy rank module was written against.
If you're ambitious enough, you could re-"plumb" the relevancy rank module to work against the Endeca Server's web services (assuming there are no search "troubleshooting" features that are no longer supported in OEID). At this point, you'd have something completely custom, and helpful, if you could get it to work.

What is ranked list ?

Hi SAP-ABAP Experts .
(a.) What is ranked list ? How it is different from simple list disply or ALV display .
May some body give any small example of ranked list ?
(b.) Difference b/t Report Painter and Sql Query ?
Regards : Rajneesh

hi ,
Ranked lists
You can use the APPEND statement to create ranked lists in standard tables. To do this, create an empty table, and then use the statement:
APPEND <wa> TO <itab> SORTED BY <f>.
The new line is not added to the end of the internal table <itab>. Instead, the table is sorted by field <f> in descending order. The work area <wa> must be compatible with the line type of the internal table. You cannot use the SORTED BY addition with sorted tables.
When you use this technique, the internal table may only contain as many entries as you specified in the INITIAL SIZE parameter of the table declaration. This is an exception to the general rule, where internal tables can be extended dynamically. If you add more lines than specified, the last line is discarded. This is useful for creating ranked lists of limited length (for example "Top Ten"). You can use the APPEND statement to generate ranked lists containing up to 100 entries. When dealing with larger lists, it is advisable to sort tables normally for performance reasons.
Examples
DATA: BEGIN OF WA,
        COL1 TYPE C,
        COL2 TYPE I,
      END OF WA.
DATA ITAB LIKE TABLE OF WA.
DO 3 TIMES.
APPEND INITIAL LINE TO ITAB.
WA-COL1 = SY-INDEX. WA-COL2 = SY-INDEX ** 2.
APPEND WA TO ITAB.
ENDDO.
LOOP AT ITAB INTO WA.
WRITE: / WA-COL1, WA-COL2.
ENDLOOP.
The output is:
          0
1         1
          0
2         4
          0
3         9
This example creates an internal table ITAB with two columns that is filled in the DO loop. Each time the processing passes through the loop, an initialized line is appended and then the table work area is filled with the loop index and the square root of the loop index and appended.
DATA: BEGIN OF LINE1,
        COL1(3) TYPE C,
        COL2(2) TYPE N,
        COL3    TYPE I,
      END OF LINE1,
      TAB1 LIKE TABLE OF LINE1.
DATA: BEGIN OF LINE2,
        FIELD1(1) TYPE C,
        FIELD2     LIKE TAB1,
      END OF LINE2,
      TAB2 LIKE TABLE OF LINE2.
LINE1-COL1 = 'abc'. LINE1-COL2 = '12'. LINE1-COL3 = 3.
APPEND LINE1 TO TAB1.
LINE1-COL1 = 'def'. LINE1-COL2 = '34'. LINE1-COL3 = 5.
APPEND LINE1 TO TAB1.
LINE2-FIELD1 = 'A'. LINE2-FIELD2 = TAB1.
APPEND LINE2 TO TAB2.
REFRESH TAB1.
LINE1-COL1 = 'ghi'. LINE1-COL2 = '56'. LINE1-COL3 = 7.
APPEND LINE1 TO TAB1.
LINE1-COL1 = 'jkl'. LINE1-COL2 = '78'. LINE1-COL3 = 9.
APPEND LINE1 TO TAB1.
LINE2-FIELD1 = 'B'. LINE2-FIELD2 = TAB1.
APPEND LINE2 TO TAB2.
LOOP AT TAB2 INTO LINE2.
WRITE: / LINE2-FIELD1.
LOOP AT LINE2-FIELD2 INTO LINE1.
    WRITE: / LINE1-COL1, LINE1-COL2, LINE1-COL3.
ENDLOOP.
ENDLOOP.
The output is:
A
abc 12          3
def 34          5
B
ghi 56          7
jkl 78          9
The example creates two internal tables TAB1 and TAB2. TAB2 has a deep structure because the second component of LINE2 has the data type of internal table TAB1. LINE1 is filled and appended to TAB1. Then, LINE2 is filled and appended to TAB2. After clearing TAB1 with the REFRESH statement, the same procedure is repeated.
DATA: BEGIN OF LINE,
        COL1 TYPE C,
        COL2 TYPE I,
      END OF LINE.
DATA: ITAB LIKE TABLE OF LINE,
      JTAB LIKE ITAB.
DO 3 TIMES.
LINE-COL1 = SY-INDEX. LINE-COL2 = SY-INDEX ** 2.
APPEND LINE TO ITAB.
LINE-COL1 = SY-INDEX. LINE-COL2 = SY-INDEX ** 3.
APPEND LINE TO JTAB.
ENDDO.
APPEND LINES OF JTAB FROM 2 TO 3 TO ITAB.
LOOP AT ITAB INTO LINE.
WRITE: / LINE-COL1, LINE-COL2.
ENDLOOP.
The output is:
1         1
2         4
3         9
2         8
3        27
This example creates two internal tables of the same type, ITAB and JTAB. In the DO loop, ITAB is filled with a list of square numbers, and JTAB with a list of cube numbers. Then, the last two lines of JTAB are appended to ITAB.
DATA: BEGIN OF LINE,
        COL1 TYPE I,
        COL2 TYPE I,
        COL3 TYPE I,
       END OF LINE.
DATA ITAB LIKE TABLE OF LINE INITIAL SIZE 2.
LINE-COL1 = 1. LINE-COL2 = 2. LINE-COL3 = 3.
APPEND LINE TO ITAB SORTED BY COL2.
LINE-COL1 = 4. LINE-COL2 = 5. LINE-COL3 = 6.
APPEND LINE TO ITAB SORTED BY COL2.
LINE-COL1 = 7. LINE-COL2 = 8. LINE-COL3 = 9.
APPEND LINE TO ITAB SORTED BY COL2.
LOOP AT ITAB INTO LINE.
WRITE: / LINE-COL2.
ENDLOOP.
The output is:
         8
         5
The program inserts three lines into the internal table ITAB using the APPEND statement and the SORTED BY addition. The line with the smallest value for the field COL2 is deleted from the table, since the number of lines that can be appended is fixed through the INITIAL SIZE 2 addition in the DATA statement.
SQL query is used for the fetching data from different tables,while report painter is used to display the data in some format.

Ranking feature not working in RoboHelp 8 - FlashHelp project

I'm testing RoboHelp 8, we use FlashHelp because we like the skins. I just converted my project from RH7 to RH8 and am doing testing of new features.
After I generated my converted FlashHelp project, i selected to view it on my C drive. I did a search for "wash account". The results display 18 topics but NO ranking information.
Out of curiosity, I generated the same project using WebHelp --- the Ranking works fine.
Search setup in the project layouts for FlashHelp and WebHelp are the same:
Enable Highlight Search Result (with gray color selected for highligh)
Enable substring search
What's the problem with FlashHelp in RH8 with ranking?
Will I have the same problem when I finally get RoboHelp Server 8 up and use FlashHelp Pro as our primary layout?
Please don't tell me that ranking only works with WebHelp or WebHelp Pro in RoboHelp 8.

Hi! Ranking works with WebHelp Pro when project is published using RoboHelp Server 8. You do have to make sure if you want the topic to be ranked highest that the keyword is in the topic title and sub-titles as well as in the body.
I've done no more testing in regards to ranking with FlashHelp Pro because we haven't moved to RoboHelp 8.
Hope this information is useful.

When I click on my user ID when I'm signed in I can see my email address under 'Public Statistics' - yet I can't see anybody else's. Is it only me that can see it? I ask because I really don't want my email address visible in case spam robots read it - this might be a silly question to an experienced user of this forum but do I need to worry? Thanks! Dave T.

Dimension Search - Rel Rank Not Working

I see for 6.4.0, 6.4.1, and 6.4.1.1 there is a known issue:
IFCORE-1637: A dimension search query with D=* produces results ordered
according to the default dimension value ranking, regardless of the value
of the Dk (Dimension Search Rank) parameter. Relevance ranking works as
expected for other types of dimension search queries
Has anyone figured out an acceptable workaround that doesn't involve post-processing to re-sort?

Ah, I think I answered this in your other thread. D=* isn't really a search (it's actually a special feature they added in a few releases ago) to list all dimension values. My guess is that since it's not a search, the MDEX doesn't pass the results through relevancy ranking to re-order them.
Note also that D=* can be very very slow in a production environment. Building out the dimension values + ancestors can be very slow.
Also, when you start working with D=* you'll notice that it can do some strange things. For instance, if your hierarchy includes:
Electronics->Cameras->Lens
.... then in the results you will see:
- Electronics
- Electronics->Cameras
- Electronics->Cameras->Lens
So you'll probably want to do some post-processing + caching anyway because of that.

[suggestion] make rank display optional.

2 posts and I get.. "Congratulations! You have a new rank in Skype Community"
Seriously ? "Novel Adventurer" ?
That is just 2 words thrown together, and grammatical, and contextual nonsense.
No books are being discussed, and no surprises or interesting things have happened. Equally I am also not a book, surprising or remotely interesting.
Is there a way to disable this pointless rank display ? It seems I can disable kudos, but not this !
I am not a child, and don't require enticement to post. I only need a valid reason.
Post counts and kudos are fine, but there is no need to create a competitive edge with posts, as it only breeds idiocy and spam.
The quest for prizes and ranks is what cripples Yahoo answers, as no matter what level of knowledge, the quest is to win a gold crown, not actually help people.
This leads to "political" voting on posts, thus corrupting the idea of having any form of user ratings.
In the forums I moderate, it is quite clear that often people with the most to say, regularly have the least to contribute.
Ranks are decided by the staff and awarded to those that deserve it. They are then a true badge of honour.
In some of the gaming sites and services I use, they are becoming a migraine inducing display of worthless awards for playing a game, visiting a page, clicking a button, scratching your ear, or putting your shoes on the correct feet.
In between this mess of adverts, awards and people shouting for attention, you often struggle to find valuable content.
I have no desire to show an auto-generated rank here, and no desire to see other peoples.
I would like to see the rank display equally as optional as the more valuable kudos, which could then become more valuable.
You already know this to be true, as kudos is what you display on the front page.
about.me/dr.flay

The word "novel" is not only a noun, it is also an adjective and is used correctly in that context.
Of all the issues facing the Skype platform this seems a bit nitpicky... if you don't care for ranking systems then simply ignore them. Surely, as you state, you are "not a child" and so filtering this information out while reading threads should be an effortless skill.
I have moderated several forums as well, and I understand what you are saying in regards to "rank boosting" via meaningless posts, but I seriously do not find that to be an issue on this site. I do not think any user wants to achieve rank on a SKYPE community site for any other reason other than genuine interest in helping users or the service. Furthermore the ability to hide ranks will do nothing to solve the problem of rank boosting; at that point what you are asking for is a tedious aesthetic change.

Rel Rank Not Working with Boost & Bury Catridge

Hi everybody,
I am facing problem on record boost and bury,
The individual records that are selected for boost or bury. It is my understanding that, while we can boost or bury certain target records,
the unselected records would still be ranked according to the Rel Rank strategy, unless a sort property was engaged (Price, Width, etc.).
The cartridge does have drop-downs for Sorts and Relevance Ranking, both of which I switch to default,but the ranking of the unselected records still seems incorrect.
I have set Relevance Ranking using EQL,
String relStrategy = "static(P_ImageValid,descending),nterms,maxfield,glom,static(P_VendorInventory,descending),static(P_Popularity,descending)";
ERecRank relRank = new ERecRank("Site_Search", relStrategy, "matchall");
query.setNavRelRankERecRank(relRank);
I am using PBX-0.6.
Can any one help me out, how can i get result in Relevance Ranking order.
Any help is appreciated.
Thanks,
Sunil

Sunil
You need to use the stratify as part of the rel rank strategy. Here is an example using the pbx example wine app with crossfield match turned on in the search interface 'All' . This is just the parameters but it shows you how to construct the rel rank with bury and boost.
In order for the query * portion to respect you current rel rank strategy as defined in the 'All' search interface you will need to construct a Ntx query like so and not use Ns.
&Ntx=mode+matchallpartial+rel+stratify(collection()/record[P_WineID="89955"],collection()/record[P_WineID="73036"],*),All
Hope this helps
