<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Arial",sans-serif">OCLC Metadata Quality teams implement a variety of measures—both manual and automated—to improve the quality and usefulness of WorldCat data. These extensive and ongoing efforts
ensure that WorldCat data supports the needs of our membership and our global network of thousands of libraries across a wide range of services. As the technologies and tools that allow us to do this important work evolve, we are continually exploring new
methods for enriching, repairing, and de-duplicating WorldCat records—data that powers the global discovery and sharing of library resources.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Arial",sans-serif">At OCLC, we believe Artificial Intelligence (AI) is at its best when guided by human expertise. Our journey with AI is a partnership—where the insights and values of library
professionals shape how AI serves communities. A core component of many AI systems is machine learning, which involves training algorithms on data to enable them to make predictions or decisions without explicit programming.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Arial",sans-serif">We’ll soon implement the latest of our AI record-merging technology as part of our ongoing efforts to resolve duplicate records in WorldCat. On 11 February 2025, we will do a
test run of 500,000 record pairs, targeting only print English books in WorldCat, and merging 500,000 duplicate records. Print English books represent the largest category of duplicates in WorldCat and is the format that has been most rigorously tested and
improved in our machine learning de-duplication activities to date. <o:p></o:p></span></p>
