The results show that our proposed scheme significantly outperforms ACM Portal in terms of retrieval precision as measured by most common metrics in Information Retrieval including Normalized Discounted Cumulative Gain (NDCG), Expected Reciprocal Rank (ERR) as well as a newly introduced lexicographic rule (LEX) of ranking search results.
Precision, recall and F-measure are commonly-used evaluation metrics in information retrieval and machine learning.

In this regard, some evaluation metrics are commonly used to describe the results obtained on an information retrieval system, namely precision, recall and F1 [10], which are classical metrics commonly used in information retrieval tasks.
By applying precision and recall metrics, which are common in information retrieval domain [24], it becomes clear that to maximize the precision, one only needs to consider very few or possibly just the most relevant terms and to discard all others.
Appropriate oversight can facilitate the integration process by promoting interoperable standards, assisting in the development of quality control metrics for information used in CDS tools, and assessing the impact of the tools on outcomes and performance measures.
In informal terms, good metrics provide information that helps one avoid costly mistakes, and good metrics cost less than the expected of the mistakes one avoids by using them.
We never store anyone's emails on our servers, only the minimum information needed to provide email metrics (only information found in the email header, only for those emails on which the user requests metrics).
When no previous information exists, the metrics (in both time and frequency) will not use CSI information.
However, some important conclusions in the application of partial metrics to information sciences cannot be obtained in this way.
And you don't want information or metrics in the deck about your business that look stale or outdated.
