"./result" folder contains results on a sample of 50k Yelp reviews.

We will take Ubuntu for example.

• python 2.7

$ sudo apt-get install python

• numpy

$ sudo apt-get install pip
$ sudo pip install numpy

• scipy

$ sudo pip install scipy

• scikit-learn

$ sudo pip install sklearn

• TextBlob and data for its POS tagger

$ sudo pip install textblob
$ sudo python -m textblob.download_corpora

• lxml

$ sudo pip install lxml

$ ./run.sh  

We will take Yelp dataset as an example.

Input: dataset folder. There are one sample Yelp review dataset (yelp) and one NYT news dataset (nyt).

DataPath='data/yelp'

Input data file path.

RawText='data/yelp/yelp_sample50k.txt'

Input: type mapping file path.

• Format: "type name \TAB typeId \n". "NIL" means "Not-of-Interest".

TypeFile='data/yelp/type_tid.txt'

Input: stopword list.

StopwordFile='data/stopwords.txt'

Output: output file from candidate generation.

• Format: "docId \TAB segmented sentence \n".
• Segments are separated by ",". Entity mention candidates are marked with ":EP". Relation phrases are marked with ":RP".

SegmentOutFile='result/segment.txt'

Output: entity linking output file.

• Format: "docId \TAB entity name \TAB Original Freebase Type \TAB Refined Type \TAB Freebase EntityID \TAB Similarity Score \TAB Relative Rank \n".
• Download Seed file for Yelp dataset.
• Download Seed file for NYT dataset.

NOTE: Our entity linking module calls DBpediaSpotLight Web service, which has limited querying speed. This process can be largely accelarated by installing the tool on your local machine Link.

SeedFile='result/seed.txt'

Output: data statistics on graph construction.

DataStatsFile='result/data_model_stats.txt'

Output: Typed entity mentions.

• Format: "docId \TAB entity mention \TAB entity type \n".

ResultFile='result/results.txt'

Output: Typed mentions annotated in the segmented text.

ResultFileInText='result/resultsInText.txt'

Threshold on significance score for candidate generation.

significance="1"

Switch on capitalization feature for candidate generation.

capitalize="1"

Maximal phrase length for candidate generation.

maxLength='4'

Minimal support of phrases for candidate generation.

minSup='10'

Number of relation phrase clusters.

NumRelationPhraseClusters='50'
