What do you think about our new web site?

Love it, indeed
Really good solution
Same as old one
The old one was better
This is a new option

AI based scientific search engine aims to accelerate the research process

RATE THIS! +45
Posted in Science on 8th Nov, 2015 10:37 PM by AlexMuller

The Allen Institute for Artificial Intelligence (AI2) this week launches its free Semantic Scholar service, which allows scientific researchers to quickly cull through the millions of scientific papers published each year to find those most relevant to their work.

 

Leveraging AI2's expertise in data mining, natural-language processing and computer vision, Semantic Scholar provides an AI-enhanced way to quickly search and discover information. At launch, the system searches over three million computer science papers, and will add new scientific categories on an ongoing basis..

 
"No one can keep up with the explosive growth of scientific literature," said Dr. Oren Etzioni, CEO at AI2. "Which papers are most relevant? Which are considered the highest quality? Is anyone else working on this specific or related problem? Now, researchers can begin to answer these questions in seconds, speeding research and solving big problems faster."
 
With Semantic Scholar, computer scientists can:
 
• Home in quickly on what they are looking for, with advanced selection tools. Researchers can filter results by author, publication, topic, and date published. This gets the most relevant result in the fastest way possible, and reduces information overload.
 
• Instantly access a paper's figures and tables. Unique among scholarly search engines, this feature pulls out the graphic results, which are often what a researcher is really looking for.
 
• Jump to cited papers and references and see how many researchers have cited each paper, a good way to determine citation influence and usefulness.
 
• Be prompted with key phrases within each paper, to winnow the search further.
 
Using machine reading and vision methods, Semantic Scholar crawls the web, finding all PDFs of publicly available papers on computer science topics, extracting both text and diagrams/captions, and indexing it all for future contextual retrieval. Using natural language processing, the system identifies the top papers, extracts filtering information and topics, and sorts by what type of study and how influential its citations are.
 
It provides the scientist with a simple user interface (optimised for mobile) that maps to academic researchers' expectations. Filters such as topic, date of publication, author and where published are built in. It includes smart, contextual recommendations for further keyword filtering as well. Together, these search and discovery tools provide researchers with a quick way to separate wheat from chaff, and to find relevant papers in areas and topics that previously might not have occurred to them.
 
Only a small number of free academic search engines are currently in widespread use. Google Scholar is by far the largest, with 100 million documents. However, researchers have noted problems with the current generation of these search engines.
 
"A significant proportion of the documents are not scholarly by anyone's measure," says Peter Jacso, an information scientist at the University of Hawaii who identified a series of basic errors in search results from Google Scholar. While some of the issues have recently been fixed, says Jacso, "there are still millions and millions of errors."
 
"Google has access to a lot of data. But there's still a step forward that needs to be taken in understanding the content of the paper," says Jose Manuel Gomez-Perez, who works on search engines and is director of research and development in Madrid for the software company Expert System.

Semantic Scholar is good idea and can help scientists get most out of published material. However, according to number of scientists, the key step in ensuring quality and impact is evaluation before work is published

Finding out published facts is one thing and evaluating them another. Both are important but for evaluation more than AI is clearly required Reply
