MITIE: library and tools for information extraction
Hi,
First of all thank let me thank you for this great tool.
We are using MITIE via python 2.7. To my best knowledge we have to convert our strings from unicode to plain bytes before passing them to MITIE.
When using tokenize_with_offset this can lead to some offset detected in the middle of some unicode character spanning over multiple bytes which results in "UnicodeDecodeError: 'utf8' codec can't decode bytes in position 4-5: unexpected end of data" after attempt for decode.
Any ideas?
Many thanks,
Jakub
Sourceforge has a troubling history of hijacking projects and should be considered harmful.
Github has arbitrary file downloads associated with releases (git tags). An admin should be able to add the data download for MITIE to the repo's releases and away from Sourceforge.
I'd like to build a simple sentence classifier using the spectral embeddings a simple average-of- bag-of-words approach.
Thinking about forking this and creating a model using dlib, but it might make sense anyway to write some functions which just return the embeddings for a list of tokens which can then be wrapped in python and other bindings. Let me know what you think
Good afternoon.
Thanks for such awesome library.
I'm getting an error Invalid range given to ner_training_instance.overlaps_any_entity(). It overlaps an entity given to a previous call to add_entity().
.
Can you please explain me what is going on?
Thanks again.
from the comments in the code base, I understand that the confidence score can range from negative to positive value larger than 1. But it's unclear to me that when I have a result with score 1.3, I'm still not sure how confidence this value is, because I don't have a [min, max] range in mind. If possible, may I have some statistical background in how this value is calculated? thanks!!
Hello,
I just have started with MITIE, I would like to understand how can i create a model for binary relationship.
Unfortunately I need italian models so I must create them from scratch. Reading the examples i found a good way to create NER models (here: https://github.com/mit-nlp/MITIE/blob/master/examples/java/TrainNerExample.java)
and here: https://github.com/mit-nlp/MITIE/blob/master/examples/java/NerExample.java for BinaryRelationDetector, the problem is how can i create a .svm ? and how can I train it?
Is there a tutorial to understand how can i create a good binary relation model ?
Thank you for your support!
Hi , when trying to run face_detection.cpp
by g++ -o output -lpng -ljpeg -O3 -I.. ../dlib/all/source.cpp -lpthread -lX11 face_detection_ex.cpp
./output test.jpg
exception thrown!
Unable to load image in file test.jpg.
You must #define DLIB_PNG_SUPPORT and link to libpng to read PNG files.
Do this by following the instructions at http://dlib.net/compile.html.
the instructions was not clear for me
Note also that if you want to work with jpeg/png files using dlib then you will need to link your program with libjpeg and/or libpng. You also need to tell dlib about this by defining the DLIB_JPEG_SUPPORT and DLIB_PNG_SUPPORT preprocessor directives.
i have installed libjpeg and libpng and added the flags ... but can"t figure out what's wrong
I would like to point out that identifiers like "MITLL_MITIe_H__
" and "MIT_LL_CONLL_PaRSER_H__
" do not fit to the expected naming convention of the C++ language standard.
Would you like to adjust your selection for unique names?
For my project I also need Coreference between sentences to extract information. Is there a good way with MITIE. Any help or pointers will help.
Thanks
Do you have any documentation on how to install or use the wordrep tool. I attempted to build it with cmake but haven't had any success.
I attempted to adapt the steps in the ReadMe for /tools/ner_stream:
cd tools/ner_stream
mkdir build
cd build
cmake ..
cmake --build . --config Release
but I am getting this error.
-- Check size of void*
CMake Error: The following variables are used in this project, but they are set to NOTFOUND.

I dont see an example for custom relationships in java. Is this supported? How can I learn more about how to use this feature?
Hi there,
Can I add more entities to the existing ner_model.dat model in MITIE-models folder?
Thanks,
Hello Davis,
I am training a NER where in I have about 63 sentences with lot of key works per sentence. This is primarily wikipedia extracts and I am training the words for a specific domain.
My cpp code is @ https://github.com/skprasadu/wikipedia-extraction-framework/blob/master/train_movie_relation/train_my_ner.cpp . And my main code @ https://github.com/skprasadu/wikipedia-extraction-framework/blob/master/train_movie_relation/train_relation_extraction_example.cpp calls the train method.
When I run the training process, it takes a long time, that is understandable, but the memory growth is crazy, it sucks up close to 16gb to complete the NER. Can you see what I am doing wrong?
Can you tell me how to optimize this?
Thanks
Krishna
Are there any plans to update mitie on the NPM? It's almost a year old, and I suspect many users would want to have mitie integration in Node as exists in Java, Python, and other languages.
Hi Davis,
Thank you so much for this high performance open source library. I have one question that I couldn't find an answer to wrt training the entity recognizer.
I would like to take advantage of already known entities, but also be able to recognize entities not already known to the dictionary. For e.g. the wikidata project provides millions of entities and it would be nice to seed the model with those known entities. Couple of approaches I can think of:
Hello,
This library is really like a dream.
Right now, I need to have Java api to train customized model. So is it possible to provide Java API by using https://github.com/bytedeco/javacpp.
Thanks.
Hi, I've come across this library, and found it is really amazing! The accuracy is even better than Stanford NER demo!
Although I understand it contains a high dimensional space with over 500,000 dimensions, is it possible to reduce the model size?
MITIE is a cool tool and much more focused and ease of use. I have Cygwin on windows and company restriction is that I cannot have VS.Net..
Can someone guide me how to build it. Thanks in advance.
Krishna
Hi guys,
I am using MITIE for java. I see that your example python program, shows how to train the ner, with a sentence and indices.
However, I am using MITIE for java.
How would I do the same thing in java?
For example, I need to train the NER, to extract the 'holiday' entity from: When is Christmas?
I am using the compiled java library you linked to.
Is the NER process fast, and does it consume a lot of memory?
P.S. By the way, for NER, is this library better than OpenNLP and others? What's the advantage in using this library over others? Does it have state of the art advanced algorithms?
Is there any memory leak? its taking a lot of memory for a very few training samples .
Its getting killed after printing this
num feats in chunker model: 4095
train: precision, recall, f1-score: 0.984615 0.984615 0.984615
now do training
num training samples: 198
I observed the memory usage and saw that it kept on increasing gradually once it reaches here, as if in each iteration some memory is getting filled garbage.
Hi there,
Can you explain what does total_word_feature_extractor.dat in MITIE-models contain?
Thanks in advance.
Hi guys,
I am working on a c++ project that requires named entity recognition and text classification.
For the entity recognition, I discovered this MITIE library, which is fast and excellent.
I would also really like to see text classification (c++) built into the project, since entity recognition and text classification can complement each other.
For example, OpenNLP has text classification. Can you guys create a similar text classification, where I have the data in Tab-spaced format.
Example training data:
category text
If you guys do not have this or not going to implement this, can you please guide me to a C++ library that has good text classification. I am aware of implementations in other languages, but I need to do this in C++.
It would be really great if you machine learning wizards can include a C++ library for text classification!
In the example it mentioned it looks at morphological features. What kind of features are they? Thank you!
I'm currently writing a paper, and I'd like to include a reference to the MITIE system. However, there's no mention of it on the CSAIL (?) site, nor any author names, etc.
Can you suggest a paper or technical report that I could cite? - it would be very helpful (and possibly good for the authors too).
All the Best (and thank you for releasing such excellent software)
Martin
:-)
Davis,
Just found a small cosmetic error (missing closed ']' mark) on how ner_stream
produces the output for the last detected entity when it's not in a proper sentence (not ended with punctuation).

I've tried to used wordrep to train the word embedding on a specialized corpus. However a std::bad_alloc
occurs during the process:
number of raw ASCII files found: 127
num words: 200000
saving word counts to top_word_counts.dat
number of raw ASCII files found: 127
Sample 50000000 random context vectors
Now do CCA (left size: 50000000, right size: 50000000).
std::bad_alloc
I've tried to launch gdb (after compiling in DEBUG mode) to see the error, but there is no stacktrace.
The training data is quite large (but fits in RAM), but it contains some non-ASCII characters (the files are encoded in unicode). Could this be due to encoding?
I have seen good number of examples of ner and binary relationship, are there plans for Sentiment Analysis?
Also can I get an example of binary_relation_detector_trainer in Java. It will help.
Thanks in advance.
I ran into a few problems on OS X with the instructions for Using MITIE from a Java program:
Also note that you must have Swig 1.3.40 or newer, CMake 2.8.4 or newer, and the Java JDK installed to compile the MITIE interface.
In addition, it was necessary to install FFTW to get the build scripts to work properly. Without it, I was getting errors like error: fftw3.h: No such file or directory
.
That will place a javamitie shared library and jar file into the mitielib folder.
The build scripts created the javamitie.jar
and libjavamitie.jnilib
files, but I had to move them from MITIE/mitielib/java/build/lib
into MITIE/mitielib
manually. Otherwise, I saw errors like this when trying to compile NerExample.java: NerExample.java:6: error: package edu.mit.ll.mitie does not exist
.
Once you have those two files you can run the example program in examples/java by running run_ner.bat if you are on Windows or run_ner.sh if you are on a POSIX system like Linux or OS X.
In run_ner.sh
, export LD_LIBRARY_PATH=../../mitielib
doesn't have the desired effect in OS X -- you'll wind up with errors like this:
Native code library failed to load.
java.lang.UnsatisfiedLinkError: no javamitie in java.library.path
You need to use DYLD_LIBRARY_PATH=../../mitielib
instead, or set it using the -Djava.library.path
VM option.
Davis,
Any plan to support smartquotes as modern text editors these days tend to use them instead regular quotes? This may have impact on the result. For example, this is the original text.
Mozilla CEO Exit Exposes Silicon Valley’s Equality-Freedom Rift.
[ORGANIZATION Mozilla] CEO Exit Exposes Silicon Valley’s [MISC Equality-Freedom Rift] .
and this is after preprocessing (smartquotes replaced). Silicon Valley
is now detected.
Mozilla CEO Exit Exposes Silicon Valley's Equality-Freedom Rift.
[ORGANIZATION Mozilla] CEO Exit Exposes [LOCATION Silicon Valley] 's [MISC Equality-Freedom Rift]
Cheers,

Hi Davis,
Looking at the code, it seems to me that everything is language agnostic apart from the english stemmer used in text categorization.
What would be the best way to replace the stemmer with another one, or even better have multiple stemmers for different languages?
Thank you very much!
Can MITIE work with python 3?

Hi there,
I am working on integrating Mitie with Apache Tika along with Prof Chris Mattmann. It would be really helpful if the shared library for Mac OS was also added in the precompiled binaries as well as published to the maven central repository. So then Tika can use the jar directly as an external jar to enable Mitie named entity recognition.
Hi Davis,
Thanks for your help always.
We always want to reduce the memory usage. Since normally we can not control extractor, so at least we hope that multiple models can share the same extractor.
With the current C++ implementation without using pointer, it seems that there is no way to share the extractor among multiple models. I tried to write the following code in three cases.
TotalWordFeatureExtractor totalWordFeatureExtractor = TotalWordFeatureExtractor.getEnglishExtractor();
NamedEntityExtractor ner = new NamedEntityExtractor(file.getAbsolutePath(), totalWordFeatureExtractor);
The above code consumes around 680 MB JVM memory.
TotalWordFeatureExtractor totalWordFeatureExtractor = TotalWordFeatureExtractor.getEnglishExtractor();
NamedEntityExtractor ner = new NamedEntityExtractor(file.getAbsolutePath(), totalWordFeatureExtractor);
NamedEntityExtractor ner2 = new NamedEntityExtractor(file.getAbsolutePath(), totalWordFeatureExtractor);
The above code consumes around 975 MB JVM memory as following.
TotalWordFeatureExtractor totalWordFeatureExtractor = TotalWordFeatureExtractor.getEnglishExtractor();
NamedEntityExtractor ner = new NamedEntityExtractor(file.getAbsolutePath(), totalWordFeatureExtractor);
NamedEntityExtractor ner2 = new NamedEntityExtractor(file.getAbsolutePath(), totalWordFeatureExtractor);
NamedEntityExtractor ner3 = new NamedEntityExtractor(file.getAbsolutePath(), totalWordFeatureExtractor);
The above code consumes around 1.26 GB JVM memory.
For the detailed code, please refer to the following link.
https://github.com/wihoho/MITIE/blob/master/mitielib/java/maven/src/test/java/edu/mit/ll/mitie/NamedEntityExtractorTest.java#L41
Obviously, there is not what we want. The ideal case is that the memory shall still be around 690 MB even there are three different models. So I assume that using pointer in the C++ code will be the only way to overcome this issue. We would like to seek your opinions on resolving this issue because actually we are not good at C++.
Thank you.

I'm training a new NER model in MITIE on a machine with a bunch of cores. Training it with a few thousand samples takes a couple hours, so I'd really like to be able to multithread it. When I set it in my code, though, it seems to default to 4 regardless of what I set.
import sys, os, json
sys.path.append("/home/ahalterman/MITIE/mitielib")
from mitie import *
from collections import defaultdict
trainer = ner_trainer("/home/ahalterman/MITIE/tools/wordrep/build/total_word_feature_extractor.dat")
trainer.num_threads = 8
[all the other stuff here]
When I start the training, though, it says only 4 threads are in use:
now do training
C: 20
epsilon: 0.01
num threads: 4
cache size: 5
loss per missed segment: 3
Sure enough, running ps -o nlwp <pid>
says it's got 5 threads (I don't know much about multithreading so I'm not sure what that extra one is).
Any idea what's going on?

Hey guys, sorry for disturbing you.
Have the same problem while building Mitie's nodejs wrapper. It seems that an error occurs in Mitie, not in node-gyp, but I might be wrong.
What can it be? Maybe I miss something? Thanks!

Hi Davis,
I am really sorry to disturb you again. But I could not build the java interface on Windows 7.
The environment which I use is as following:
The error message is as following.

I really appreciate your help on builds on windows. Thanks a lot.
I need to handle Chinese language, so is there any method or some steps that i could try to train NER and binary relation extration model?
Thanks for any help!
Hello,
So far I'm greatly impressed with the product. The assessment in #12 is spot on and I'm looking forward to training some binary relationships as soon as I can think of an interesting one.
I was wondering if there were plans to update the basic NER model over time. Further, is there some kind of way to submit missed entities within text in an organized fashion?
This isn't be best example since it's hard to determine from the context but running
"Popular Science is your wormhole to the future. Reporting on what's new and what's next in science and technology, we deliver the future now."
missed 'Popular Science' as miscellaneous or otherwise without any kind of score.
I'm currently downloading them at 100k/sec while trying to test an automatic provisioning script and not thrilled about it :)
Sourceforge has definitely seen better days, I think.
For display of highlights natively in a web browser as a user visits pages in the wild, it is necessary to pass XPath-based offsets to the highlighting JavaScript code running in the browser. It doesn't appear that MITIE generates XPath offsets currently. This ticket is a feature request for adding such output to MITIE.
See here for further details:
It is possible to wrap a tool like MITIE with a converter that reparses the HTML and generates XPath offsets. The python example linked below works in more than half of web pages, but has issues with incomplete tags. We have experience solving this issue in some other contexts. If this feature request gets prioritized by MITIE, we would be glad to help MITIE engineers.

Hi,
I am observing some misalignment of the token indexing when calling Java method edu.mit.ll.mitie.mitie.tokenizeWithOffsets with a string containing multi-byte characters. For example, calling it with the string funny “quotation marks” and so on
produces tokens:
Token 0: index=0, value=<funny>
Token 1: index=6, value=<“quotation>
Token 2: index=19, value=<marks”>
Token 3: index=28, value=<and>
Token 4: index=32, value=<so>
Token 5: index=35, value=<on>
Note that the quotation marks are Unicode 201c and 201d. token 2's index (19) is out by 2 (it should be 17), and token 3's (28) is out by 4 (it should be 24). So there appear to be cumulative indexing errors when "multi-byte" characters are encountered.
hi. i am new to python and trying out MITIE Python API to train a named_entity_extractor. But i am getting Undefined variable: ner_training_instance error. How can i resolve that?
MITIE library makes a really exciting impression at first glance. However it would be very helpful if you could provide one or two examples of what the library actually outputs when being used on a text. Especially for people like me not totally into language processing it is hard to get a clear picture of what the library actually does and what it can be used for.
Cheers
Holger
First, THANK YOU! The world has needed this forever for the reasons you outline in the readme, so I'm very glad you're building this. Dlib is awesome as well.
I'm able to build and run the example but make test fails with:
$ make test
./ner_stream MITIE-models/ner_model.dat < sample_text.txt > /tmp/test.out
Loading MITIE NER model file...
time: 2.86sec
diff /tmp/test.out sample_text.reference-output
diff: sample_text.reference-output: No such file or directory
maybe just a git add sample_text.reference-output
?
Hello,
First I'd like to thank the makers of MITIE. It's great to have a state-of-the-art NER free for commercial use. I've been finding that it has issues identifying Amazon and McDonald's as companies, as described below.
Throughout this post I'll run the following code with different input and display the output:
toks = mitie.tokenize(eatiht.extract(fd))
ents = ner.extract_entities(toks)
[(e[1], ' '.join(toks[e[0][0]:e[0][-1]+1]), e[2]) for e in ents]
I've been finding that Amazon is usually tagged as a location. Here's an example of such a text:
"Amazon is among a host of companies asking the Federal Aviation Administration to expand the abilities of small commercial drones and the traffic control system that would monitor them."
which yields
[('LOCATION', 'Amazon', 0.6497587837582173),
('ORGANIZATION', 'Federal Aviation Administration', 1.2338242977625724)]
Here's another:
'Its earnings season again and Amazon, for the first time ever, has broken out the financial results of its cloud services division, Amazon Web Services (AWS). The results are impressive. In less than a decade, Amazon has grown AWS into a $5 billion business that is still growing at 50%.'
which yields
[('LOCATION', 'Amazon', 0.6857005959408439),
('ORGANIZATION', 'Amazon Web Services', 0.8302322174217054),
('LOCATION', 'Amazon', 0.5971181888647527)]
I've been finding similar problems with McDonald's. Take this story, for example: http://www.foxnews.com/leisure/2015/04/27/not-lovin-it-mcdonald-is-trying-to-fix-its-business/
which yields

This means that out of the 16 times McDonald's occurred, it was tagged as a PERSON 14 times and as an ORGANIZATION 2 times.
MITIE very often does quite well from what I've seen. There seem to be some major companies though for which it doesn't. I know that we can train our own models using MITIE, but it just seems like it should work for one of the most prolific companies of our time (Amazon) and a company as prevailent as McDonald's. I don't think the problem is a training/inference domain mismatch since the English section of the CoNLL 2003 NER task was a Rueters corpus and I'm applying it to news wire. Beyond training my own model, all I can think to do is find these cases MITIE gets terribly wrong and create custom rules that are used to change the output of the NER. Do you have any other suggestions?
Hi,
using the ner_conll
example I found the train-ner
script in MITIE/tools/ner_conll/train-ner
:
./ner --train-chunker eng.train_all_some_sentences_combined $THREADS > $LOG
./ner --train-id eng.train_all_some_sentences_combined $THREADS >> $LOG
./ner --test-id eng.testb >> $LOG
./ner --tag-conll-file ner_model.dat eng.testb | ./conlleval
echo $LOG
As I cannot find a executable called "ner" - I'm just wondering if it should be train-ner
instead, but the train-ner
command line arguments only provides:
parser.add_option("h", "Display this help information.");
parser.add_option("train", "train named_entity_extractor on CoNLL data.");
parser.add_option("test", "test named_entity_extractor on CoNLL data.");
parser.add_option("threads", "Use <arg> threads when doing training (default: 4).",1);
parser.add_option("tag-conll-file", "Read in a CoNLL annotation file and output a copy that is tagged with a MITIE NER model.");
See MITIE/tools/ner_conll/src/main.cpp
.
So my question is if that small train_ner
script should be updated then?
Thanks in advance (+ I'm really looking forward to train a model for German),
Stefan
Hi Team,
Could you please help me how to update a saved model with new training data? Do I have to run the entire trained samples along with the new samples to through a trainer and create a new model for updating an existing model? I tried serializing the trainer and reuse it. However since there are pointer references, I am not able to save the trainer. I am trying to periodically update my model with new samples.
Kind Regards,
rp
