regex101 has a few more distinguishing features:

- more flavor support,

- a regex debugger,

- code generator, with support for a lot of languages,

- a complete quick reference with examples,

- an extensive regex library,

- a regex quiz for "golfing" and learning purposes,

Perhaps, most importantly, it runs entirely client side and does not submit any information to the server unless you hit save (which returns a delete link to remove all data). You can even run the website and (most) of its features offline.

Regexr submits all input to the server for processing.

But, I'm biased, since I wrote regex101 :)

Typically not. Sometimes they are tagged as nominal mentions.

Don't agree. LSTM is a very good option for NER. I have personally experimented with simple FFNN and language models to accommodate variable width input and achieved very good results. I will be publishing a paper on this soon.

The system in the article fails at quite simple sentences, such as:

"Rex Tillerson is the secretary of state."

It tags "Rex Tillerson" as ORG instead of PER. If you change "is" to "was" it tags it as PER.

The unit testing feature is located in the menu on the left, under the submenu "TOOLS" (the checkbox icon).

I posted this last night but was told it was incorrect format so I'm giving it another try. Hope this is alright! Please enjoy the site and any feedback is appreciated.

Hello

I'm the creator. PCRE offers a neat feature to limit backtracking, Python does not. I still havent found a decent solution to this issue.

Javascript is run in your own browser so you'll only be screwing yourself there :p

I have thought about this, but in cases where it would be useful, it's impossible to generate a sample match string. For example, creating a match string for /(?:a|[bc])efg?/ is super simple, but for something like: /(ab(?1)*)/ it becomes much harder. Not to mention the performance hit you would see for these more complex expressions. (These are just dummy expressions for illustrative purposes, but I'm sure you get my gist.)
