Getting Started

Finding entities and relations via NLP on text and documents

To get easily started, simply install the deepsearch-glm package from PyPi. This can be done using the traditional pip install deepsearch-glm or via poetry poetry add deepsearch-glm.

Below, you can find the code-snippet to process pieces of text,

from deepsearch_glm.utils.load_pretrained_models import load_pretrained_nlp_models
from deepsearch_glm.nlp_utils import init_nlp_model, print_on_shell

load_pretrained_nlp_models(force=False, verbose=False)
mdl = init_nlp_model()

# from Wikipedia (https://en.wikipedia.org/wiki/France)
text = """
France (French: [fʁɑ̃s] Listen), officially the French Republic
(French: République française [ʁepyblik fʁɑ̃sɛz]),[14] is a country
located primarily in Western Europe. It also includes overseas regions
and territories in the Americas and the Atlantic, Pacific and Indian
Oceans,[XII] giving it one of the largest discontiguous exclusive
economic zones in the world.
"""

res = mdl.apply_on_text(text)
print_on_shell(text, res)

The last command will print the pandas dataframes on the shell and provides the following output,

text:

The NLP can also be applied on entire documents which were converted using Deep Search. A simple example is shown below,

from deepsearch_glm.utils.load_pretrained_models import load_pretrained_nlp_models
from deepsearch_glm.nlp_utils import init_nlp_model, print_on_shell

load_pretrained_nlp_models(force=False, verbose=False)
mdl = init_nlp_model()

with open("<path-to-json-file-of-converted-pdf-doc>", "r") as fr:
    doc = json.load(fr)

enriched_doc = mdl.apply_on_doc(doc)

Creating Graphs from NLP entities and relations in document collections

To create graphs, you need two ingredients, namely,

1. a collection of text or documents
2. a set of NLP models that provide entities and relations

Below is a code snippet to create the graph using these basic ingredients,

odir = "<ouput-dir-to-save-graph>"
json_files = ["json-file of converted PDF document"]
model_names = "<list of NLP models:langauge;term;verb;abbreviation>"

glm = create_glm_from_docs(odir, json_files, model_names)	

Querying Graphs

TBD

Install for development

Python installation

To use the python interface, first make sure all dependencies are installed. We use poetry for that. To install all the dependent python packages and get the python bindings, simply execute,

poetry install

CXX compilation

To compile from scratch, simply run the following command in the deepsearch-glm root folder to create the build directory,

cmake -B ./build; 

Next, compile the code from scratch,

cmake --build ./build -j

Run using the Python Interface

NLP and GLM examples

To run the examples, simply do execute the scripts as poetry run python <script> <input>. Examples are,

1. apply NLP on document(s)

poetry run python ./deepsearch_glm/nlp_apply_on_docs.py --pdf './data/documents/articles/2305.*.pdf' --models 'language;term'

2. analyse NLP on document(s)

poetry run python ./deepsearch_glm/nlp_apply_on_docs.py --json './data/documents/articles/2305.*.nlp.json' 

3. create GLM from document(s)

poetry run python ./deepsearch_glm/glm_create_from_docs.py --pdf ./data/documents/reports/2022-ibm-annual-report.pdf

Deep Search utilities

1. Query and download document(s)

poetry run python ./deepsearch_glm/utils/ds_query.py --index patent-uspto --query "\"global warming potential\" AND \"etching\""

2. Converting PDF document(s) into JSON

poetry run python ./deepsearch_glm/utils/ds_convert.py --pdf './data/documents/articles/2305.*.pdf'"

Run using CXX executables

If you like to be bare-bones, you can also use the executables for NLP and GLM's directly. In general, we follow a simple scheme of the form

./nlp.exe -m <mode> -c <JSON-config file>
./glm.exe -m <mode> -c <JSON-config file>

In both cases, the modes can be queried directly via the -h or --help

./nlp.exe -h
./glm.exe -h

and the configuration files can be generated,

./nlp.exe -m create-configs
./glm.exe -m create-configs

Natural Language Processing (NLP)

After you have generated the configuration files (see above), you can

1. train simple NLP models

./nlp.exe -m train -c nlp_train_config.json

2. leverage pre-trained models

./nlp.exe -m predict -c nlp_predict.example.json

Graph Language Models (GLM)

1. create a GLM

./glm.exe -m create -c glm_config_create.json

2. explore interactively the GLM

./glm.exe -m explore -c glm_config_explore.json

Testing

To run the tests, simply execute (after installation),

poetry run pytest ./tests -vvv -s
