Hi Armin,
I used it a while ago. I had to apply the following patch to make it work:

Hi all,
thanks for the hint. As far as I could see by a quick glance into the docs, it integrates UIMA AEs as Lucene TokenStream components. This is a good idea for a more sophisticated NLP analysis in my opinion. However, I think it is not suited for largely scaled-out applications. If your UIMA pipeline needs serious processing power, the Lucene pipeline is a bottleneck because you either write directly into a Lucene index (thus single threaded) or into Solr (threads equal to the number of Solr instances). Your could, of course, also write multiple Lucene indexes in parallel which would require a merging-post-processing step.
Either way, I feel you would give up on the scaling capabilities of UIMA. Perhaps you could use UIMA AS from the inside of a Lucene analysis component but it seems overly complicated to me.
With LuCas I can use the full power of UIMA and just send the results into a Lucene index or Solr. All the big processing stuff can be done with UIMA AS or, in my case, with an arbitrary large set of synchronized CPEs.
My UIMA pipeline runs two and a half days on 10 (older) server machines for the complete set of documents I am working with. I wouldn't want to squeeze this into a Lucene analyzer.
Again, correct me if I'm mistaken and my points wouldn't be valid. I'd be glad to learn about alternatives, and be it only to be properly informed.
Best,
Erik

Hello Erik,
in Lucene 4.9 (maybe earlier), you can replace the Lucene analyzer
with a UIMA pipeline. At least the docs say so. I don't know how good
it is becaus I've never used it.

Re: AW: AW: Lucas
Posted by Erik Fäßler <er...@uni-jena.de>.
Hi all,
actually, I don't use LuCas anymore to write a Lucene index but rather to send the created documents to Solr or ElasticSearch. There are two reasons I continue to use LuCas: It's field merging capabilities and the term cover mechanics.
Regarding the field merging: I have a lot of machine learning components in my pipeline, nothing I could do within a Lucene analyzer. So when I recognize entities with an ML component in the text and each entity has an ID, then please consider this example:
Barack Obama entered the White House.
Let's pretend we would require an ML system to recognize "White House" as THE one White House and let's say we gave it the ID "entity1".
My goal is to be able to search for the ID in the same way I would do using a synonym filter, thus finding a document by terms that originally were not included in this document's text, AND be able to correctly highlight the corresponding text snippet. So, when I search for "entity1" (e.g. because the user wants to see documents dealing with the White House), I want to find the above example document with the string "Whit House" highlighted.
LuCas can do this for me be aligning or merging the text TokenStream with the entity TokenStream, just as it is done within the CAS itself.
If this functionality can be achieved without using LuCas, please tell me, I'd be happy to switch to up-to-date maintained default-components. Until now I am under the impression this cannot be done by another component.
The term cover mechanics allow me to easily distribute terms across document fields in a predefined, possible overlapping, set division, the set cover. I use it to automatically deal with a lot of faceting fields. Here, I can model n:n mappings from CAS indexes to Lucene fields, e.g. mapping terms originating from one CAS index to 10 Lucene fields, or the other way round.
Again, if this is easily possible with another existing, maintained component, please point me to it.
In short: I, too, ultimately don't use Lucene but Solr/ES. However, LuCas has some (Lucene) document fine-tuning-tuning capabilities I need/work with.
This means: I don't necessarily need LuCas in an Lucene-updated version. I use it more as a fine-tuned TokenStream-smith. I could require it to be updated in the future when LuCas is not able to express a specific feature of a newer Lucene version.
I hope this wall of text was understandable, thanks for reading through it ;-)
Best,
Erik

Hello,
when I helped out with the Solr integration we still used UIMA to index
documents in our search servers.
We don't do that anymore. The indexing code now runs directly as a
MapReduce job for batch indexing, and
in Storm for real time indexing.

Hi Erik and Jörn,
I've used Solr in the meantime. It is so easy to quickly write a CAS consumer that sends documents to a Solr web service. Writing to a Lucene index is minimally more work. Could this be the reason why nobody cares about the outdated version? Is there really a need for Lucas and Solrcas anymore? What do you think? It would be nice to have some opinions on this.
Of all people reading this list, who wants to have a Lucas or Solrcas for the current version of Lucene?
Cheers,
Armin

Re: AW: Lucas
Posted by Erik Fäßler <er...@uni-jena.de>.
I am using LuCas in production in the last SNAPSHOT version that can be found in the SVN but not in the maven repository. I was also not aware a patch would be required to get it to work, I am using it in its current SVN state, including the splitter filter.
I would be willing to help with a migration and contribute to discussions/plans. However, I won't have time to do it all on my own, especially since I use it as a bridge to Solr/ElasticSearch that kind of remedies the version difference. Thus I use it with newer Solr/ES versions without problems so far.
I will be on vacations for two weeks, after that I'd be available for contributions.
Best,
Erik

It would probably nice to migrate those to the current versions of
Lucene/Solr.

Hi Renauld,
that's nice, thank you. Are you using Lucene 4.x or an older version?
It's a while ago, that I've asked that question and I didn't get much response. Is the project dead? Is it just to easy to code a simple annotator for Lucene or Solr to justify the effort maintaining Lucas and Solrcas?
Cheers,
Armin

Hi Armin,
I used it a while ago. I had to apply the following patch to make it work:
