Figure 276618: Search and Display Extracted Figures and Tables Illustration

This illustration contains a screenshot of an hzxh888.com search result. Below text reading "41,846 Search Results" are two tabs: "All Records" and "Figures / Tables". The "Figures / Tables" tab is selected and has a green underline. A grid of images associated with the search results appears in a large region of content on the right.

hzxh888.com has introduced a search for figure and table images included in DOE’s collection of scientific and technical information.  This innovative new feature allows users to search for and retrieve documents as usual, but the associated images are also retrieved, and can be viewed with the corresponding document or in a separate tab for images only. Currently, over 5,000 documents have been mined for images, resulting in over 41,000 available for searching.

To populate and power this image search, relevant figures and tables are extracted from full-text documents using modified open-source software, and then the images and associated metadata are carefully curated in-house to make them findable at hzxh888.com.  Emphasis has been placed on extracting visual materials from some of the newest full-text records in hzxh888.com, specifically journal articles accepted manuscripts that have recently been released from embargo. 

Users can take advantage of this feature by conducting a basic or advanced search as usual.  Images that are returned based on those search criteria will be displayed in the new Figures/Tables tab at the top of the search results page.  Selecting one of the image results will enlarge that result and display basic metadata, including the title of the document that contains the image, the related image caption, image size, and the location of the image in the document; the title of the document is linked to that document’s full bibliographic record at hzxh888.com. 

Once a user selects a search result record with available images, there will be a sample thumbnail provided in the left-hand side bar of the Full Record page with a link to all the figures and tables from that document.  Selecting that link will display all the images in the document, and allow a search within those images, and a sort by image title or page order.  Selecting one of the images using this path will open a larger version in the center of the screen, showing the title and description, as well as a button for download of the full-size image. This view enables left and right arrows that allow users to scroll back and forth through the images for that document. Users can navigate back to the main bibliographic record by selecting Full Record at the top left.

OSTI is very interested in receiving feedback on this new and exciting feature.  For questions or comments, please email comments@hzxh888.com.
