Complete List of Matchers

IMatcher Javadoc / Source Code

Generic matcher interface which just implements one method called match. It gets a source and a target ontology / knowledge graph, an input alignment and additional parameters.

Keywords: I Matcher

MatcherURL Javadoc / Source Code

RawMatcher which implements the minimal interface for being executed under the SEALS platform. The only method which should be implemented is the align(URL, URL, URL) method.

Keywords: MatcherURL

MatcherString Javadoc / Source Code

Keywords: Matcher String

IMatcherCaller Javadoc / Source Code

A matcher interface which allows the matcher to call other matchers as well.

Keywords: I Matcher Caller

MatcherFile Javadoc / Source Code

For this matcher the results file that shall be written can be specified.

Keywords: Matcher File

MatcherPipelineSequential Javadoc / Source Code

Executes all matchers one after the other.

Keywords: Matcher Pipeline Sequential

MatcherCombination Javadoc / Source Code

Combines multiple matchers. This can be very inefficient because the alignment has to be serialized after each matcher. Better use a more specialized MatcherCombination like: TODO

Keywords: Matcher Combination

SealsWrapper Javadoc / Source Code

This class implements the SEALS interface (via MatcherURL) and calls the provided matcher class (the matcher class is provided via a file in the SEALS package in folder /conf/extenal/main_class.txt ). If this class is renamed or moved, then the name needs to be adjusted in matching assembly project in file SealsDescriptorHandler.java (method finalizeArchiveCreation - line 45).

Keywords: Seals Wrapper

MatcherDockerFile Javadoc / Source Code

This matcher creates a docker container based on a given docker image name. Within this container a matcher server should be started. Therefore it will use the MatcherHTTPCall internally to run the matcher. For this Matcher to work you have to add the following dependency to YOUR pom:

 
<dependency>
    <groupId>com.github.docker-java</groupId>
    <artifactId>docker-java-core</artifactId>
    <version>3.2.7</version><!--maybe update version-->
</dependency>
<dependency>
    <groupId>com.github.docker-java</groupId>
    <artifactId>docker-java-transport-httpclient5</artifactId>
    <version>3.2.7</version><!--maybe update version-->
</dependency>
 

With this in place everything should work.

MatcherSeals Javadoc / Source Code

This matcher wraps the SEALS client such that a SEALS zip file or folder can be executed. If multiple matcher should be instantiated, have a look at MatcherSealsBuilder buildFromFolder.

Keywords: Matcher Seals

MatcherCLI Javadoc / Source Code

Matcher for running external matchers (require the subclass to create a command to execute).

Keywords: MatcherCLI

MatcherCLIFromFile Javadoc / Source Code

This component adds negative samples to the alignment. The number of negative samples is defined by an absolute number.

Keywords: Add Negatives Randomly Absolute

AddNegativesViaMatcher Javadoc / Source Code

This component adds negative correspondences to the input alignment via a recall optimized matcher. This also means that the input alignment should contain positive correspondences. After applying the recallMatcher given in the constructor, a new alignment is returned which contains positive (equivalence relation) and negative(incompat relation) correspondences. With the help of this alignment, supervised matchers can be trained.

Keywords: Add Negatives Via Matcher

AddNegativesRandomlyShare Javadoc / Source Code

This component adds negative samples to the alignment. Negatives are added as long as the share of negatives is not fullfilled.

Keywords: Add Negatives Randomly Share

ParisMatcher Javadoc / Source Code

This is a wrapper for PARIS matching system by Fabian Suchanek et al. The corresponding paper is called PARIS: Probabilistic Alignment of Relations, Instances, and Schema. It will download the matcher if not already done and execute it as an external process. The equivalence files of the last iteration are then read into a YAAA aligment. It is tested to run with java 1.7 and 1.8.

Keywords: Paris Matcher

MatchPropBasedOnInstances Javadoc / Source Code

Keywords: Match Class Based On Instances

MatchPropBasedOnClass Javadoc / Source Code

Graph-based Matcher: Checks all matched classes and matches also properties between them (domain and range) with mean value of both classes. Example:

 foo  ---already matched with c=0.5---  foo
  |                                      |
 blub  --new with c=(0.5+0.4)/2=0.45--  bla

BackgroundMatcherStandAlone Javadoc / Source Code

Matcher which applies String matching and matches then with the provided background knowledge source and strategy.

Keywords: Background Matcher Stand Alone

BackgroundMatcher Javadoc / Source Code

Template matcher where the background knowledge and the exploitation strategy (represented as ImplementedBackgroundMatchingStrategies) can be plugged-in. This matcher can be used as matching component. It is sensible to use a simple string matcher before running this matcher to increase the performance by filtering out simple matches. If you want a pre-packaged stand-alone background-based matching system, you can try out BackgroundMatcherStandAlone.
This matcher relies on a similarity metric that is implemented within the background source and used in BackgroundMatcher#compare(String, String).

Keywords: Background Matcher

SimpleStringMatcher Javadoc / Source Code

A relatively simple matcher that can be used before running BackgroundMatcher to filter out simple matches.

Keywords: Simple String Matcher

StopwordExtraction Javadoc / Source Code

Keywords: Synonym Text Matcher

ExactStringMatcher Javadoc / Source Code

Matcher which creates correspondences based on exact string match.

Keywords: Exact String Matcher

ScalableStringProcessingMatcher Javadoc / Source Code

 Function<String, Object> lowercase = (text) -> text.toLowerCase();
 ScalableStringProcessingMatcher matcherOne = new ScalableStringProcessingMatcher(Arrays.asList(
              new PropertySpecificStringProcessing(equality, 1.0, RDFS.label),
              new PropertySpecificStringProcessing(lowercase, 0.9, RDFS.label)

OpenEAMatcher Javadoc / Source Code

This matching module uses the OpenEA library to match entities. It uses all correspondences which are provided through either the constructor or match method(inputalignment) with equivalence relation to train the approach. It only need positive correspondences and samples negative correspondences on its own.
If you apply your own configuration you can use the parameters from openEA and also the following additional parameters:

  • predict_top_k - the number of matching entities which should at least retrived for one single entity
  • predict_min_sim_value - the similarity measure which should be applied for every correspondence. All sim values are greater than the given one (not equal or greater).
