Semantic search—a new option to help make sure you don’t miss critical patent information.

LexisNexis® Semantic Search powered by PureDiscovery can help improve your search results by adding concepts that relate to your search query. You can then review the concepts suggested, assign relative importance (weighting), eliminate concepts you don’t wish to use, and even add more concepts of your own. Once you run the semantic search and review the results, you can narrow your search using either semantic or Boolean searching.

Benefits

  • Save time—enter what you do know about the technology or topic you’re researching. Then let the semantic technology uncover related concepts and terms.
  • Greater recall—utilize the semantic search option to bring more results to you that are related to your search query, whether or not you used the specific terms in your initial search.
  • Greater precision—by combining Boolean and semantic search technology, your results will be highly relevant to the technology or topic you are researching, even when terms used in the patent or non-patent prior art is vague or obscure.
  • Full transparency—you do not have to guess what’s being done away from your view and control. The terms and concepts suggested by the semantic technology are returned to you for your review before the actual search is run.
  • Greater control—you are in complete control of editing and prioritizing the terms and concepts you choose to include in your research. 

Features

We use Latent Semantic Analysis (LSA), a type of machine learning that ensures that the semantic search returns more relevant documents that are deemed on-point based on concepts, not just key words.

Our semantic intelligence began learning with the USPTO patent index and over 2.5 million Elsevier journal articles.  And we continue to provide more patent-related documents for learning so that it is growing every day.

Fully federated  so that you can apply the semantic search to not only the LexisNexis® sources on which it is available, but also to Web sources you may include in your search.

The semantic search option is available to you when using these solutions and sources:

  • TotalPatent™
  • PatentOptimizer
  • Elsevier Journals
  • IP.com and Research Disclosure
  • Selected news and business sources
  • LexisNexis® Toolbar, when you select sources on the toolbar that have semantic search as an option.
