    Abstract
    A commonly used technique for improving search engine performance is result caching. In result caching, precomputed results (e.g., URLs and snippets of best matching pages) of certain queries are stored in a fast-access storage. The future occurrences of a query whose results are already stored in the cache can be directly served by the result cache, eliminating the need to process the query using costly computing resources. Although other performance metrics are possible, the main performance metric for evaluating the success of a result cache is hit rate. In this work, we present a machine learning approach to improve the hit rate of a result cache by facilitating a large number of features extracted from search engine query logs. We then apply the proposed machine learning approach to static, dynamic, and static-dynamic caching. Compared to the previous methods in the literature, the proposed approach improves the hit rate of the result cache up to 0.66%, which corresponds to 9.60% of the potential room for improvement.

    Abstract
    The Association for Manitoba Archives has created a database where members can deposit archival descriptions to provide a central search for users. Library of Congress Subject Headings (LCSH) were chosen as the controlled subject vocabulary to use in the descriptions, but changes were made to LCSH to better describe material about or by Indigenous peoples. Examples include: the word "Indian"; geographic place embedded in terms such as "Indians of North America"; changes related to Manitoba peoples specifically; and miscellaneous changes not part of a larger pattern. New terms were also added.
