QUESTION
I'm new to Python and nltk, so I would really appreciate your input on the following problem.
Goal:
I want to search and count the occurrence of specific terminology in tokenized sentences which are stored in a pandas DataFrame. The terms I'm searching for are stored in a list of strings. The output should be saved in a new column.
Since the words I'm searching for are grammatically inflected (e.g. cats instead of cat) I need a solution which not only displays exact matches. I guess stemming the data and searching for specific stems would be a proper approach but let's assume this is not an option here, as we would still have semantic overlaps.
What I tried so far:
In order to further handle the data I preprocessed the data while following these steps:
- Put everything in lower case
- Remove punctuation
- Tokenization
- Remove stop words
I tried searching for single terms with str.count('cat')
but this doesn't do the trick and the data is marked as missing with NaN
. Additionally, I don't know how to iterate over the search word list in an efficient way while using pandas.
My code so far:

QUESTION
I'm using solr 6.6.0. (and The core was created with "sample") When I importing rich document (here HTML) using ExtractingRequestHandler, unnecessary line feed code(\n) and tab characters(\t) are indexed. I tried setting MappingCharFilterFactory etc, but it was ineffective. I also referred to the following URL, but there was no effect.
How do you prevent tabs and newline codes (\ n, \ r \ n, \ t) from being indexed?
[Steps I took]
- access to "http://localhost:8983/solr/#/sample/documents"
- select my core (sample). And click "document" link in left menu.
fill the forms
- Request-Handler "/update/extract"
- Document Type File Upload
- Documetn (s) test.html
- Extracting Req. Handler Params * unspecified
- Commit Within 1000
- Overwrite true
Select "text.html" above and execute it.

...ANSWER
Answered 2017-Jun-26 at 10:22Indexing and storing are two different things. To make it simple : - indexed content is used to perform search - stored content is used to be returned in the search results
You may remove those special characters from your indexed content playing with the analysis chain as you have done ( I have not tested them but they may be ok). But removing those special characters from the stored content ( the content that is returned in the response) is a different thing. You need to clean that content before it reaches Solr OR use some custom Solr plugin to do it at update request processor time.
In case you just don't want that to reach your API response, you could clean just the solr response in your intermediate API layer and return the clean content to the client.
QUESTION
I try to lemmatize a text using spaCy 2.0.12 with the French model fr_core_news_sm
. Morevoer, I want to replace people names by an arbitrary sequence of characters, detecting such names using token.ent_type_ == 'PER'
. Example outcome would be "Pierre aime les chiens" -> "~PER~ aimer chien".
The problem is I can't find a way to do both. I only have these two partial options:
- I can feed the pipeline with the original text:
doc = nlp(text)
. Then, the NER will recognize most people names but the lemmas of words starting with a capital won't be correct. For example, the lemmas of the simple question "Pouvons-nous faire ça?" would be['Pouvons', '-', 'se', 'faire', 'ça', '?']
, where "Pouvons" is still an inflected form. - I can feed the pipeline with the lower case text:
doc = nlp(text.lower())
. Then my previous example would correctly display['pouvoir', '-', 'se', 'faire', 'ça', '?']
, but most people names wouldn't be recognized as entities by the NER, as I guess a starting capital is a useful indicator for finding entities.
My idea would be to perform the standard pipeline (tagger, parser, NER), then lowercase, and then lemmatize only at the end.
However, lemmatization doesn't seem to have its own pipeline component and the documentation doesn't explain how and where it is performed. This answer seem to imply that lemmatization is performed independent of any pipeline component and possibly at different stages of it.
So my question is: how to choose when to perform the lemmatization and which input to give to it?
...ANSWER
Answered 2019-Jul-13 at 07:42If you can, use the most recent version of spacy instead. The French lemmatizer has been improved a lot in 2.1.
If you have to use 2.0, consider using an alternate lemmatizer like this one: https://spacy.io/universe/project/spacy-lefff
QUESTION
I've recently begun working on a sentiment analysis project on German texts and I'm planning on using a stemmer to improve the results.
NLTK comes with a German Snowball Stemmer and I've already tried to use it, but I'm unsure about the results. Maybe it should be this way, but as a computer scientist and not a linguist, I have a problem with inflected verb forms stemmed to a different stem.
Take the word "suchen" (to search), which is stemmed to "such" for 1st person singular but to "sucht" for 3rd person singular.
I know there is also lemmatization, but no working German lemmatizer is integrated into NLTK as far as I know. There is GermaNet, but their NLTK integration seems to have been aborted.
Getting to the point: I would like inflected verb forms to be stemmed to the same stem, at the very least for regular verbs within the same tense. If this is not a useful requirement for my goal, please tell me why. If it is, do you know of any additional resources to use which can help me achieve this goal?
Edit: I forgot to mention, any software should be free to use for educational and research purposes.
...ANSWER
Answered 2017-Jul-11 at 11:33As a computer scientist, you are definitely looking in the right direction to tackle this linguistic issue ;). Stemming is usually quite a bit more simplistic, and used for Information Retrieval tasks in an attempt to decrease the lexicon size, but usually not sufficient for more sophisticated linguistic analysis. Lemmatisation partly overlaps with the use case for stemming, but includes rewriting for example verb inflections all to the same root form (lemma), and also differentiating "work" as a noun and "work" as a verb (although this depends a bit on the implementation and quality of the lemmatiser). For this, it usually needs a bit more information (like POS-tags, syntax trees), hence takes considerably longer, rendering it less suitable for IR tasks, typically dealing with larger amounts of data.
In addition to GermaNet (didn't know it was aborted, but never really tried it, because it is free, but you have to sign an agreement to get access to it), there is SpaCy which you could have a look at: https://spacy.io/docs/usage/
Very easy to install and use. See install instructions on the website, then download the German stuff using:
QUESTION
Assume a very large corpus of any inflective language. Does the following make sense? By applying LSA on such corpus, words with similar concepts converge together in vector space, thus inflected word forms reffering to the same concept should ideally be identical with their lemma in the space. With such assumption, any lemmatization or stemming of queries or corpus is not necessary. Or am i totally wrong?
...ANSWER
Answered 2019-May-22 at 15:17According to the founders of LSA, stemming is not necessary. Though, I think there is general disagreement in the literature about this. I have read a few papers where stemming was found to improve results for a given information retrieval task.
Generally, there is recent research that shows stemming does not help in topic modeling and may even hurt topic coherence.
