Re: extract multi-features for one solr feature extractor in solr learning to rank

Hi Jianxiong, this is definitely interesting. Briefly reviewing the paper you linked the use case seems clear : You want similar "family" of features, to be calculated on each field. Let's take as example the TF feature, you may want to define in the features.json only one feature including all

Backup not working

How to use Wordnet in solr?

Hey, I'm planning to use Wordnet and I want to know how. There's a class called *WordnetSynonymParser *, does anybody use it? It says it is experimental... I'm using solr 5.2.1 Briefly speaking about my needs: I have different collections in different languages (fr, pr, sp, en). When the user

Re: How to use Wordnet in solr?

I am not sure WordnetSynonymParser is accessible from Solr. At least I never heard anybody mention it. I am also aware of https://github.com/nicholasding/solr-lemmatizer but that's lematizer, not a synonym builder. But perhaps there are some lessons/code in there that could be useful. Regards,

Re: Modify solr score

It isn’t going to work. The score is not an absolute relevance measurement. It only says that the first document is more relevant than the second, and so on. Scores are not comparable between different queries. The score cannot be used to say that the first hit for query A is a better match

Re: How to use Wordnet in solr?

Hi Pablo, with wordnet format , Solr will just parse synonyms from a different file format [1] . The rest will work exactly the same. You will use a managed resource to load the file and then potentially update it. If you were thinking to use directly the online resource, you may need to customize

Re: Modify solr score

It has been discussed countless times, never rely on score values. Rely on the ranking of your results. It seems you model a as a least of keywords and then you just run a query for each topic. Essentially for you, a is a query. The ranking of your results will already be affected by how many

Re: Modify solr score

Since we report the score, we think there will be some relation between them. As far as we know scoring (and then ranking) are calculated based on tf-idf. What we want to do is to make a qualitative ranking, it means, according to one topic we will tag documents as "very related", "fairly

Re: Modify solr score

Well, maybe I explain it wrong. We have entry points, each of them are related to a topic. It mens that when we select the first topic all information has to be related in some way to this vocabulary. So, it can work since we select documents not related to each vocabulary of every entry point.

Re: Modify solr score

Using a minimum score cut off does not work. The score is not an absolute estimate of relevance. The idf component of the score is a whole-corpus metric. When you add or delete documents, the scores for the exact same query can change. wunder Walter Underwood wun...@wunderwood.org
