- mark_l_watson 14y agoThe Stanford NLP tools are very good, and also GPLed, which works for a lot of projects. If the GPL doesn't work for you, the Apache OpenNLP project is also good.
- mark_l_watson 14y agoBTW, it is not just having software packages to use: it is a ton of work obtaining and preparing training data. That said, Stanford NLP and OpenNLP tools come out of the box with trained models for tagging, entity name recognition, etc. For lots of uses, these pre-trained models will work well for you.
- tcwc 14y agoThe Stanford parser is great, but isn't really the same. The Stanford entity recogniser is limited to the standard types of people, places, companies, but we identify and disambiguate into a far richer ontology from wikipedia, and can recognize topic abstractions that aren't explicitly mentioned. Also we found the Stanford tools (and the other open source NLP tools) were difficult to integrate into "production" apps for various reasons. One big one was performance - we aim to run the full parsing and extraction pipeline on an average news story in a few hundred milliseconds, which can be an order of magnitude faster than the others.
- JPKab 14y agoHow does your offering compare to Calais from Thomson-Reuters? Edit: To be specific, it looks very similar. What do you have that Calais doesn't?
- mark_l_watson 14y agoI have been using the free tier (50K API calls per day) of Open Calais for years and have also used it in code examples in three books I have written. One thing that Open Calais does that I really like is that they attempt to have a single URI uniquely identifying recognized named entities. This is useful because, for example, when it recognizes President Bill Clinton, you get a reference to a unique URI, even if his name, title is different in different processed texts. Thomson-Reuters bought ClearForest several years ago, thus acquiring Calais. If you are interested in text mining, and if you haven't experimented with Open Calais, then please put that on your TODO list.
- gsharma 14y agoJust tried http://nlp.stanford.edu:8080/parser/ http://nlp.stanford.edu:8080/parser/ it only allows up to 70 characters for parsing.
- mark_l_watson 14y agoTry downloading the distribution of code and data and run it locally. Java stuff, maven based, easy to run. Use the example code listed on the installation web page to see how to set it up.
- gsharma 14y agoAhh, thanks. I didn't realize it was just a demo. Sounds like a fun weekend project.
