Show HN: Search for a domain expert on Reddit
- wingerlang 8y agoWhen I searched for my own account, it didn't show up. When I searched for a topic, it showed me a user with the same name as the topic. When I did find some users claimed to be experts, I found their mood over the year and the main link was to a HN comment of them. I am not sure how to use this, what makes a user a domain expert? It's all kinda confusing.
- lettergram 8y agoI only show accounts that were active in the past year (in the subreddits it’s tracking). Do you have examples of the errors? I’d love to try and figure out the issue. Regarding a domain expert it’s identified by the terms a person uses and related terms people are interested in. The learn more section might help clear some of that up.
- wingerlang 8y agoNot tracking all subreddits makes sense I guess. But I searched for "Jailbreak". But got a user with that username. Searching for "ios programming" shows me some guy wyager and the discussion link is to HN, not reddit.
- lettergram 8y agoThanks for the heads up -_- The full blown system creates what I call "metaprofiles" merging profiles across various domains. Basically, it can identify people based on conversation (regardless of username or domain). One thing I do, is create these "metaprofiles" and will return the first linked account. Apparently, I forgot to add a "data source" as an input to the function, thus you may get some of the cross profiles.
- dewey 8y agoCan you just use the name “Reddit” in your Domain like that?
- CarVac 8y agoI searched for photography and none of the regulars on /r/photography (including myself) came up.
- lettergram 8y agoFYI the system just looks at a subset of subreddits: /r/dataisbeautiful /r/news /r/worldnews /r/technology /r/programming /r/cars /r/stock market /r/cryptocurrency /r/all Basically didn't want to build an insanely large database for a simple demo.
- chx 8y agoWell that kills it. The gems of reddit are to be found in small subreddits. For example, awesome bag advice can be found in /r/onebag/ (41k subscribers) /r/ManyBaggers/ (783 only but don't let that fool you, the knowledge in that place is astonishing) and somewhat on /r/BuyItForLife/ (500k). Even that 500k is very small.
- klohto 8y agoEveryone I searched for have an unhappy mood...

- forgottenpass 8y agoSemantic analysis belongs to the third category in "lies, damn lies, and statistics." I'm sure it's slightly better for Metacortex's real use case - which is an employee surveillance system - because people won't use strong language, hyperbole, share their real opinions, or talk about certain topics as much in professional communication. But I still find the whole domain to be a fraud with just enough signal in the noise to trick people.
- dsfyu404ed 8y agoThis tool is interesting but it is fundamentally an exercise in turd polishing because Reddit is a completely terrible place to get "expert" advice. It's designed to be a place for show and tell with commentary and false appearance of consensus. If you want expert advice you should be asking for it somewhere that's properly formatted for long form discussion. You should also seek out advice in a specialized community, not a general one like Reddit. For every piece of good advice on Reddit there's ten pieces of terrible advice and ten pieces of mediocre advice you could find yourself on Google offered up by the riff-raff that happen to be passing through that day. Reddit is just polite 4chan. If you want expert advice to somewhere where only people who are interested in the topic you want advice on are (usually forums). Edit: Also this tool thinks I am an expert in hipsters. I like to think I'm an expert in calling people hipsters.
- gepoch 8y agoCalling people hipsters is the most hipster thing of all. Source: am a hipster.
- fhood 8y agoI thought the most hipster thing was hating stuff that is popular.
- acconrad 8y agoIs anyone aware of a catalogue that houses all of the various forum domains? For example, if you want to seek fashion advice, probably better to head over to StyleForum instead of /r/malefashionadvice (or HypeBeast for streetwear). I know someone asked on here recently for investing forums and were pointed to Corner of Berkshire and Fairfax (as well as /r/securityanalysis) but that is indeed better than /r/investing or /r/wallstreetbets which are garbage.
- Balero 8y agoI think r/wallstreetbest is supposed to be garbage, but with lots of in jokes.
- jwilk 8y agoThe same thing but for HN: https://news.ycombinator.com/item?id=17942981 https://news.ycombinator.com/item?id=17942981
- josefresco 8y agoSearched for "trump", site returned PoppinKREAM so this seems pretty accurate!

- mfoy_ 8y agoLove his write-ups. Shame the people who don't want to hear his message can just say "fake news" and carry on... :(
- yorwba 8y agoIf you want to find mods and bots, try searching for "please". It works on the HN version to pick out dang and sctb and it seems to work on Reddit as well. There are some false positives, however. E.g. a comment saying "Zuck Fuck" being interpreted as discussing "please" might be due to uncleaned word vectors. https://www.reddit.com/r/worldnews/comments/85y46f/facebooks_stock_tumbles_again_value_drops_by_more/dw1bxc4/ https://www.reddit.com/r/worldnews/comments/85y46f/facebooks...
- jwilk 8y agoI tried https://hnprofile.com/author_profiles?utf8=%E2%9C%93&search=please https://hnprofile.com/author_profiles?utf8=%E2%9C%93&search=... to no avail; there's neither dang nor sctb on the first 5 pages.
- lettergram 8y agoSo.. the system learns what the subject of a sentence is over time. It's since learned "please" is not a subject, so I imagine that's what's dropped them in the results. Still appear first for YCombinator, because that's the links they constantly post

- dimitry12 8y ago@lettergram In lettergram.com, when it says "{} opinion ({}) in {} separate discussions" - are these discussions from Reddit and HN?
- lettergram 8y agoIt’s what ever is fed into the system. So currently it’s monitoring 12 or so data sources. I could monitor more, but I figure I’ll scale it with interest.
- dimitry12 8y agoCool! What are they? Have you considered adding the feature of listing the conversations which contributed to the score?
- lettergram 8y ago100% of the conversations on this website come from subreddits (main ones listed in another comment here). Overall I also monitor some forums, hacker news, and others for https://projectpiglet.com https://projectpiglet.com which identifies company insiders then recommends trades. So I don't feel comfortable with sharing exact sources. Regarding the score - The paid version I'm offering to companies has said feature. It also has a bunch of other items as well, find duplicate accounts, automated related project notification, etc.
- dimitry12 8y agoThanks! I will consider trying paid version.
- lettergram 8y ago> The paid version I'm offering to companies has said feature. Should note! That is not the projectpiglet.com version (that wont show you any user information, don't want you to pay unnecessarily). I'm offering the paid version which can be hosted and deployed by a given company internally. To do that you'll need to contact direct via email.
- DanBC 8y agoI searched for "suicide". I got a list of people back who had interesting opinions in a thread about suicide, but who are not domain experts. It's an interesting idea though, and it worked a lot better than I was expecting it to. The limitations are clear from the description on the page ("note we only track a small number of subreddits").
- indentit 8y agoisn't "domain expert" and "reddit" contradictory?
- ketralnis 8y agoFortunately I'm not the kind of person people would be searching for, but this just seems impolite. Posting to an internet forum on a topic that interests you is not an opt-in to have random internet people or reach out to you asking for free advice. If I were a domain expert I wouldn't want to be searched for on Reddit using a tool like this because the implicit goal is to then be spammed about it. If I wanted to be reached out to, I'd say so on a web site somewhere
- megamindbrian2 8y agoNeither is it proof of being an expert.
- scopecreep 8y agoBut semi-anonymous posts on social media are? If so there's a lot more Navy SEALs than I was lead to believe.
- jsonne 8y agoInteresting. As someone who has a marketing subreddit dedicated to my content that's about 3k people I wish this was a bit more inclusive outside large subreddits. There's a lot of value in the "longtail" subreddits as it were.
- thethirdone 8y agoA few characters (' ) ( :) (And probably more) lead to an error screen: https://redditprofile.com/author_profiles?utf8=%E2%9C%93&search=%27 https://redditprofile.com/author_profiles?utf8=%E2%9C%93&sea... https://redditprofile.com/author_profiles?utf8=%E2%9C%93&search=%28 https://redditprofile.com/author_profiles?utf8=%E2%9C%93&sea... https://redditprofile.com/author_profiles?utf8=%E2%9C%93&search=%29 https://redditprofile.com/author_profiles?utf8=%E2%9C%93&sea... https://redditprofile.com/author_profiles?utf8=%E2%9C%93&search=%3A https://redditprofile.com/author_profiles?utf8=%E2%9C%93&sea...
- lettergram 8y agoThanks for catching the error! Should be fixed now, for reference the error was because I was estimating the count. Turns out that couldn't handle only special characters.
- mothsonasloth 8y agoInteresting stuff, how do you calculate a users "mood". Are you willing to explain your algorithm?
