Simple application using sentece embedding to project the documents in a high dimensional space and find most similarities using cosine similarity.

The purpose is to demo and compare the models. To deploy in scale, it is necessary to compute and save the document embeddings to quickly search and compute similarities.

The first load take a long time since the application will download all the models. Beside 6 models running, inference time is acceptable even in CPU.

The demo text has 4 sentences about each topic: Apple, Operating Systems, Java and Python.

It is possible to see the semantic search works well filtering out only documents about the specific query, even tought the query doesn't have the exaclty words in documents.

The Raw BERT performs poorly (as expected)

It is necessary to download the Infersent model 1 and glove.840B.300d.txt.

Download and put the files in the infersent_files in each respective folders.
