Great guide..One doubt..is this a better approach in 2024, given this tutorial was made in 2022 ? Do you recommend the same method now or using the latest LLMs ?
We have the problem such that we have extract the text from images after extracting we need to recognise the particular entity from that text for eg. Entityname: weight and extracted text be djskhsns jjsnbss. 20 gm then the model need to give 20gm as in output. For what should be our approach
Great work Pradip ! Really liked the way you explained the application part. Few Follow up questions 1. Is there any alternative few shot learning model. Say we have very less tagged data. Does Spacy NER model holds good if we have limited data points. 2. Do we have a rough estimate how much samples are required for each label ? 3. Is there any open source tagging tool which could help in building this dataset ?
Hi Sarthak, Appreciate your support. 1. Yes its not few shot learning we are using fine tuning of model. Spacy has good model for NER , you can use Spacy Transformers model. 2. Ideally we should have 100 examples for each NER tag. 3. These are two good open source tools github.com/tecoholic/ner-annotator github.com/doccano/doccano
Very helpfull video mate. One question please, what if i want to create and train the model from scratch and fine tune one of the existing spacy models? Thank you
Good tutorial. But when I run the python command for training, the output ends at '[INFO] Added vectors: en_core_web_lg' and then the cell stops executing. I do not even get into the training pipeline where I get the losses etc. What could be the reason for this?
As per my understanding there is issue with updating model, it forgets existing NER tags. Better train from scratch again. This might be usefull github.com/explosion/spaCy/issues/2124
Well, this code work well for custom data. But, when we train for particular entities. It forgot all the earlier entities he was able to predict. How to deal with this?
Thanks a lot Pradip for this Video!!! It was very helpful. I just had 1 question here. So after we train the model, when the model figures out the annotations on the unseen text, does it consider the context of the sentence because the training data merely had the start, end and tag_name. So while making predictions will it consider the context or will it simply predict based on the positions. I know you used "long" model. I just wanted to understand if "long" model will consider context or should we use "en_core_web_trf". please clarify
@@FutureSmartAI Thank you So Much Pradeep. That really helps. Also how do we measure the performance of these models if it did well or not. For example for classification we measure performance using F-measure or ROC Curves. However for this how do we measure the performance of these models
Hi Pradip , Really great work on the video!!. I tried to follow your steps you followed the steps to create the NER model but the output varied. For example on the training dataset It recognized only Pathogen though there are medical conditions and Name and location related entities in my test data. Any suggestions to improvise the model
Nice one thank you for this simple and easy NER, so wanted to know does this only work for these medical only now? will it be in conjunction with the _lg model ???
To train ner model, we need start,end location of entity. If you already have entities then you can pragmatically find where they start and end and eventually create training data.
@@FutureSmartAI i have already trained model like in your tutorial. And now i have testing data which includes not only text, but also entities. 1 entitie for 1 text. It's easier. I just want to say to my model "Find this concrete entite in this concrete text" and he gives me some concrete sentence from text. I really need to solve that problem. How can i do it? Thank you!
sir i have a question you use directly a json file containing indexes of conditions is their any other method can i extract tags without making json file or i do it manually tag labels for each condition and then convert into json
instead of using the base model (spacy.blank("en") i am using the spacy.load("en_core_web_md") model. But whenever I pass my json file with custom annotations, my model-best only uses those new custom entities and not the one from the en_core_web_md model. Also, the md model is about 44mb big but my new model-best and model-last are 4mb each. Shouldn't they be around 44mb since its building ON TOP of the preexisting model? please help
it forgets old data, called catastrophic forgetting since new training data does not contain those tags. I don't know about the size difference but it may be related to embeddings lack of presence in new saved model ?
Thanks Prajith. Spacy transformers (en_core_web_trf) model use roberta-base which is improved version of BERT. You can read more about models and their architecture here spacy.io/models/en
When I try to load blank spacy model using "nlp = spacy.blank('en')", it throws an error "ModuleNotFoundError: No module named 'spacy.gold'" Could you please help with this ?
Really good tutorial!! Do you think NER could be used for Intelligent Data Capturing especially invoices data? And if we have to extract data from pdf, can NER be used?
Yes we could but we will need training data if invoices has custom entities. One good solution will OCR service like textract + GPT-3 fro custom entities detection. textract even extract tables and forms from documents.
Hi i have tried this and its working but I have query. I have created a training model for particular one word "Software Engineer" with custom object created. Now text has only this word "Software Engineer" so I have set start and end as 0 and 17. Now its identifying Software Engineer as DESIGNATION (label) but its also identifying other words as DESIGNATION. For example "Hi, This is Software Engineer." So its taking This is as DESIGNATION as well. As per given example it will work for fixed sentence but for real time example its not working. Please help me for same. Please check below logs (This is, Software Engineer, . My, name is Victor, . I, am from, USA) doc This is entity DESIGNATION: This is Software Engineer entity DESIGNATION: Software Engineer . My entity DESIGNATION: . My name is Victor entity DESIGNATION: name is Victor . I entity DESIGNATION: . I am from entity DESIGNATION: am from USA entity DESIGNATION: USA

Wonderfully explained! Great Help!😊
Glad you think so!
Thanks pradip for this video...Really helped🤓👍
My pleasure 😊
Thanks mate... was looking for this and luckily found it. Many thanks
Glad I could help. Do watch other videos related to GPT-3, Transformers etc.
Awesome video. Learnt alot
Glad to hear it!
Great video. keep it up
Thanks, will do!
Thanks for the video tutorial this is really useful for the project I'm working on

Glad you liked it
hello! thank you for your video! But I've a question. How can I calculate confidence on every entity? i need %
Can we train the similar way if we have to extract patterns in the data like 7digits_4digits pattern?
Really Nice.
Thanks!
Very helpfull video mate. One question please, what if i want to create and train the model from scratch and fine tune one of the existing spacy models?
Thank you
Really well explained with spacy :) Could you also explain for Spacy LLM model with Openai ?
Thanks. Sure
Which are the tools to auto label the data or to create custom data for training can you please give some info about it

Good tutorial.
But when I run the python command for training, the output ends at '[INFO] Added vectors: en_core_web_lg' and then the cell stops executing.
I do not even get into the training pipeline where I get the losses etc. What could be the reason for this?
Thanks for the video. Just a quick question, is it possible to perform NER using GPT ?
Yes, absolutely
Here is video related to NER using GPT-3

Thanks for the quick response
How can we update the already trained spacy ner model with a new dataset instead of retraining from the beginning?
As per my understanding there is issue with updating model, it forgets existing NER tags. Better train from scratch again.
This might be usefull

@@FutureSmartAI thanks 👍
Great tutorial. After predictions, how can you place the predicted named entities and their values into a dictionary to be used later on?
Hey that should be normal python code. can you ask this in discord if you face any issue
Well, this code work well for custom data. But, when we train for particular entities. It forgot all the earlier entities he was able to predict. How to deal with this?
It is called "catastrophic forgetting".
you can find more details here: github.com/explosion/spaCy/issues/2204

I didn't face this issue. are you using google colab or local GPU?
@@FutureSmartAI Google colab
Great video...thanks. Can you tell me How to get confidence score for each entity for custom NER model?
I am not sure whether this is possible now, this thread may be helpful for you.

Nice one thank you for this simple and easy NER, so wanted to know does this only work for these medical only now? will it be in conjunction with the _lg model ???
It can work with any NER data and with any model.

Hi, I'm getting very high TOK2VEC loss and NER loss. Could you please something to reduce the same.
Can you post this in discord? if you could share screenshots that will be helpful
Thanks for great explanation Pradip.
What model does spacy NER use? Is it a BERT model?
Thanks Prajith.
Spacy transformers (en_core_web_trf) model use roberta-base which is improved version of BERT.
You can read more about models and their architecture here spacy.io/models/en
Can this be used to extract specific data points from unstructured text. Such has find the interest rate from a doc?
Yes, you can treat interest as custom entity.
When I try to load blank spacy model using "nlp = spacy.blank('en')", it throws an error "ModuleNotFoundError: No module named 'spacy.gold'"
Could you please help with this ?
Hi Which version of Spacy are you using? Our code is for v3
kaggle dataset link??
I'm getting something like, skipping training for these due to annotations misalignment, can you help?
You should check your annotations ? are they correct and consistent?
Pradip if we want to tag a word meter so we have perimeter and meterboard as text will it still classify both of them to the tag meter
Depends on your training data. NER is not string matching, entities will be identified as per patterns in your training data
