Which knowledge management system to choose?

Question

Knowledge base

Good afternoon! Tell me which KMS can be selected for such tasks:
Knowledge base requirements:
1. Quick access to information, quick online search in a large amount of information:
• Semantic search (expansion of a search query with words that are similar in meaning);
• Search by tags;
• By content types;
• Fuzzy search (presence of typos and errors in textual information).
2. Support for a variety of document formats (HTML, PDF, Word, Excel, PowerPoint, Visio).
3. Levels of access and information protection: access control at the level of individual documents, flexible management of user rights.
4. Integration with the IT management system (we have HPSM) (search in the KB according to the classification of the request, filling in the KB according to the decision of the specialist - sending to the moderator for consideration of adding the solution as a KB article).
5. Versioning.
6. Categorization.
7. Filtering.
8. Building tables.
9. Alerts about changes (to the person responsible for the service or the entire group in the related service).
10. News feed with the ability to attach files, add comments.
11. Comments and remarks to articles with moderator notification.
12. Logging and the ability to rollback edits.
13. Backup.
14. Lack of binding to cloud services, it is necessary to have the ability to deploy locally, within the company.
15. Regulations, normative legal acts, rules and instructions, documentation, processes.
16. Directory of regulatory information (such as: BCC - budget classification code and SPPP - directory of items of state order and others).
17. Register of free/paid software indicating analogues.
18. Register of employees.
19. Management of contact data (for example, suppliers, warranty services), communication with the current list of employees.
In my opinion, this is no longer for the knowledge base, but suddenly it is possible to enter into one product or group of products:
1. Register of contracts (deliveries to the central warehouse, tender documentation).
2. Logins / passwords (to information systems, to portals, to personal accounts), a protected area (for personal use, or groups of people).
3. Versions of the budget.
4. Journal account manager for working with quality reviews.
And most likely a completely separate software, but also suddenly there is a group of products that can work together:
1. In the user interface, display tasks in accordance with the calendar (both fixed, assigned by the manager, and personal, added by the user).
2. Accounting for software licenses.
3. Database on goods and materials.
I considered many different options, now I focused on xwiki, but it seems to me that I could have overlooked a number of any commercial products, probably due to their absence in the public domain, here the question is not to find it for free, but it is desirable that the list of requirements for the product fits as much as possible in its ability, ideally to combine all the points, in a worse scenario, the first two blocks, well, in the worst case, at least the first 19 points, although it seems to me that xwiki might be suitable for them. Perhaps someone has already faced a similar task and you have seen from your own experience that it is better not to try to combine any of the points. I would be grateful for any ideas.
From all that I have already considered: Yandex Connect, OneNote, Mediawiki, Dokuwiki, Xwiki, Confluence, smartportal.pro, zoho, kbpublisher, mindtouch, rizzoma - this is one of those that have at least something hooked, those that are absolutely nothing, even to list I will. Thanks for any ideas!

Answer 1

look at Alfresco, but maintaining / creating features is not cheap
- the easiest way is the Jira zoo with a downloaded license
or any with API - practice shows that it is easier to create functionality separately with integration than to climb into the system code
