lucene - Document similarity framework -


i create application searches similar documents in database; eg. user uploads document (text, image, etc.), , query application similar ones.

i have created neccesseary algorithms process (fingerprinting, feature extraction, hashing, hash compare, etc.), i'm looking framework, couples of these.

for example, if implement in lucene, following:

  • create custom "tokenizer" , "stemmer" (~ feature extraction , fingerprinting)
  • than adding created elements lucene index
  • and using morelikethis class find similar documents

so, lucene might choice - far know, lucene not meant document similarity search engine, rather term-based searchengine.

my question is: applications/frameworks, might fit above mentioned problem?

thanks, krisy

update: seems process described above called content based media (sound, image, video.) retrieval.

there many projects use lucene this, see: http://wiki.apache.org/lucene-java/poweredby (lire, alike, etc.), still didn't found dedicated framework ...

since you're using lucene, might take @ solr. realize it's not dedicated framework purpose either, add stuff on top of lucene comes in quite handy. given pluggability of lucene, track record , fact there lot of useful resources out there, solr might job done.

also, answer @mindas pointed to, links the blog post describing technical details @ how accomplish goal solr (but read in meantime).

linux - Does gcc have any options to add version info in ELF binary file? -

i mean whether gcc can insert source code version infor elf binary section or similar. not want change source file, add info gcc option in makefile. you can emit version info text file, turn text file object file statically link executable. the first step simple have write code: script or write version info in format plain text file. write makefile rule produce version.o version.txt, using objcopy . you'll have object file 2 useful symbols defined in it: beginning , end of textual version info. add generated object executable, , you'll able access version 2 ways: running strings on binary, or writing code in application print version string (you'll need declare start , end symbols variables in header file).

i'm using named queries fetch entities database using jpa , hibernate , came across puzzling me: how come there no default implementations of javax.persistence.parameter interface? i rather impressed how @staticmetamodel used criteriabuilder in jpa2 meaning type safety , don't have mess around setting string names. wanted apply similar of jpa1 ejb's i'm working on: dealergroup_.class: public dealergroup_ { public parameter<integer> id = new parameterimpl<integer>("id"); /// etc... } dealergroupfacade.class: // ... public dealergroup fetch(integer id) { typedquery<dealergroup> query = em.createnamedquery("dealergroup.fetchbyid", dealergroup.class); query.setparameter(dealergroup_.id, query); return query.getsingleresult(); } // ... i surprised find there no implementations of parameter interface - of course, implement myself absence makes me suspicious may mistake using in way? should implementing parameter...
