IEEE Xplore Updated – Electrical and Computing Literature

[tweetmeme source=”Intellogist” only_single=false]

There’s a lot to catch up on in the world of patent and prior art searching. Putting aside all the developments in US Patent Reform legislation (which can and probably should be it’s own post when it’s all set in stone), there’s plenty to learn about the search systems and databases you know, love, and have come to rely on. If you read on, you’ll find out about changes to IEEE Xplore–a great source of journal and conference non-patent literature–with more to come soon!


The Institute of Electrical and Electronics Engineers (IEEE) maintains the IEEE Xplore digital library. IEEE Xplore contains a comprehensive collection of full text documents in electrical engineering, computer science, and electronics journals. Access to IEEE Xplore is available to individual IEEE members and to subscribing institutions. Guests may search and access abstracts free of charge. Publications of interest are available for purchase to guests.

My computer and electrical engineering search colleagues at Landon IP love IEEE Xplore. It’s a great resource that really hones in on the non-patent literature they need, since the service and database focus on a subset of topics relevant to many of their searches.

One of the many progressive aspects of IEEE Xplore is the “faceted” search interface. Common to many newer systems, a sidebar allows users to quickly tweak and refine searches based on the most frequently occurring elements in several categories (subject, source, origin, author, etc).

The helpful Refine interface can be used for statistical analysis or to further drill down into specifics of a result set.

In their most recent collaboration, IEEE and Access worked together to “complete a comprehensive re-indexing of approximately 2.1 million of the 2.8 million IEEE article records in the IEEE Xplore® Digital Library database.”

Access had this to say about the process used for re-indexing:

To complete the latest project, Access Innovations used an implementation of Data Harmony® Metadata Extractor to determine the article’s content type and then built an improved rules base to identify content types in order for each type to be indexed in a specific way using the IEEE Thesaurus.

Using M.A.I.® (Machine Aided Indexer) provided highly accurate, rules-based indexing (text categorization) of the content types. M.A.I. is part of Access Innovations’ Data Harmony suite of knowledge management products.

Users should benefit from the re-indexing process by having access to records with better and more appropriate content tags and metadata (depending on the content, records will also include terms such as Inspec Controlled Indexing and Non-Controlled Indexing). For more information on the IEEE Thesaurus and its terms, which are directly impacted by this update, please visit the IEEE Thesaurus information page.

Have you used IEEE Xplore? What do you think of this search system? We’d love to hear from you in the comments.
