deviating number of documents and document display

Post by Jirka » Wed Jul 27, 2022 9:14 am

Dear Espacenet Team,
while working with the database, I keep noticing that the number of hits for the same search query differs quantitatively (not to small extent) and that the hit display is not the same. What is the reason for it? However, my search results should be reproducable. On the one hand, this is important for my work as a patent searcher. On the other hand, the display confuses our course participants, whom we train in working with Espacenet. Thank you very much for a quick reply!
Best regards, Kristin

Dear Kristin,

Thank you for your comments.

The Espacenet database is actually continuously updated every day from 02.00 to 11.00 hrs CET.

This would explain possible increases of hits on the same day during this period of time.

With regards to the different hit displays, this could also be due to the daily upload of new documents in Espacenet. Indeed, the result list is displayed by default according to the relevance. The algorithm then recalculates the relevance/position of hits in the result list taking into account the newly added documents.

One way to minimise the impact of these daily Espacenet uploads on your training sessions could be to show examples combined with dates or date ranges, e.g. 2015:2020. Except for the infrequent but possible upload of older documents, the number of results and display should remain unchanged.

In case you would also notice decreases in the number hits, it would help to try understand what happens if you could send some examples with screenshots mentioning the time at which they were taken, showing the query used, as well as the different number and displays of hits obtained.

Kind regards,

Andrée

If the document display is paginated, ensure that you are navigating through all pages to see the complete list. Pagination might limit the number of documents shown on a single page. Uno Online
