Cool, something I missed in Signal

No More Phone Number Swaps: Signal Messaging App Now Testing Usernames

Offering usernames will allow people to stop giving out their phone number —a sensitive piece of information— in order to connect with others on the messaging app.

@kjr still my preferred messaging app even though I only use it with my wife, kids and a friend.
@paul have you developed an app?
@kjr no, I'm more of a dabbler with code and tend to do more data processing and analysis lately.
@paul data processing and analysis... I like it. What kind of analysis do you do?
I am quite active in text data analysis.
@kjr I recently started doing some data analysis with sales data, mostly using Looker and Superset. I also have a set of personal workflows written in Python that process text notes in Obsidian, and generate some of my routine reports at work
@paul I am currently finishing two projects in Hebrew archival text analysis.
One is to detect entities (people, places, locations, dates and organizations) from archival collections and the relationships between them, so we can extract biographic information about the people: when and where born, name of the parents, organizations the person belonged, etc.
The second one is just to extract the entities, link them to bibliographic entity files and improve the search of the data and the linking between documents of different archives.
@kjr how old is the information you're working with?
@paul
The first project is Holocaust data, the customer is Yad Vashem.
The second one goes from old to brand new data. The customer is the Archive Network Israel

@kjr amazing! It must be fascinating work.
@paul
Yes, I love it.
Outside of archives, I have worked a lot with bio-medical data and with customer care data, that in the private sector.
Are you currently working for a company in your area?

@kjr

Have you or do you plan to use Relation Ontology in your projects? ➡️ http://obofoundry.org/ontology/ro.html

@paul

OBO Foundry

@rameshgupta @kjr I haven't come across this at all. 🤔 I suspect I'm not the intended audience for the tool though.

@paul @kjr

This tech is rooted in #graphDB rather than #relationalDB, although some implementations use relational db for storing triples for each edge of graph (2 vertices + edge relation). You then use #SPARQL instead of #SQL to find information.

What caught my eye was https://babka.social/@kjr/111381934379266332
& https://babka.social/@kjr/111381988654130074

#OBOFoundry is used extensively in bio sciences & research.

A schema-less graph repo could work well here, especially with new standardization around https://www.nist.gov/system/files/documents/2021/10/14/nist-ai-rfi-cubrc_inc_004.pdf

A big part of this technology is automated reasoning (not AI) with #OWL Direct Entailments & more.

In #relationalDB, you may only retrieve what you've explicitly put into the database.

In #graphDB with OWL reasoning, the system INFERS additional info beyond what you put in, based on strict definitions of Descriptive & First Order Logic.

So, you can glean additional inferences, sometimes subtle, based on what you actually input into the DB.

@paul @kjr

There is no preset schema. Just store triples like:
<x> <is aunt of> <y>.

Using configured ontologies, the system will infer x and y are both people (as opposed to Car or Furniture), even though no data type was specified, and x is female, even though no gender was entered.

<x> <occurs at> <y>.
entails x is a Process, y is a Site

<x> <occurs on> <y>.
entails x is a Process, y is Time or TemporalRegion

Non-obvious but correct conclusions may follow with intersecting triple groups
