There are quite a lot of tools to extract text from PDF files[1-4]. However the problem with most scientific papers is the hardship to get access PDF directly mostly due to the need to pay for them. There are tools that provide easy access to papers' information such as metadata or bibtex , beyond the just the bibtex information[5-6]. What I want is like taking a step forward and go beyond just the bibtex/metadata:
Assuming that there is no direct access to the publications' PDF files, is there any way to obtain at least abstract of a scientific paper given the paper's DOI or title? Through my search I found that there has been some attempts [7] for some similar purpose. Does anyone know a website/tool that can help me obtain/extract abstract or full text of scientific papers? If there is not such tools, can you give me some suggestions for how I should go after solving this problem?
Thank you

The “title” should be descriptive, direct, accurate, appropriate, interesting, concise, precise, unique, and should not be misleading. The “abstract” needs to be simple, specific, clear, unbiased, honest, concise, precise, stand-alone, complete, scholarly, (preferably) structured, and should not be misrepresentative.
An abstract summarizes, usually in one paragraph of 300 words or less, the major aspects of the entire paper in a prescribed sequence that includes: 1) the overall purpose of the study and the research problem(s) you investigated; 2) the basic design of the study; 3) major findings or trends found as a result of your ...
The function of an abstract is to describe, not to evaluate or defend, the paper. The abstract should begin with a brief but precise statement of the problem or issue, followed by a description of the research method and design, the major findings, and the conclusions reached.
If the article is on PubMed (which contains around 25 million documents), you can use the Python package Entrez to retrieve the abstract.
