The task of choosing the correct sense for a word is called word sense disambiguation (WSD). WSD algorithms take an input word w in its context with a fixed set of potential word senses Sw of that input word and produce an output chosen from Sw. In the isolated WSD task, one usually uses the set of senses from a dictionary or theasurus like WordNet.
In the literature, there are actually two variants of the generic WSD task. In the lexical sample task, a small selected set of target words is chosen, along with a set of senses for each target word. For each target word w, a number of corpus sentences (context sentences) are manually labeled with the correct sense of w. In all-words task, systems are given entire sentences and a lexicon with the set of senses for each word in each sentence. Annotators are then asked to disambiguate every word in the text.
In all-words WSD, a classifier is trained to label the words in the text with their set of potential word senses. After giving the sense labels to the words in our training data, the next step is to select a group of features to discriminate different senses for each input word.
The following Table shows an example for the word 'yüz', which can refer to the number '100', to the verb 'swim' or to the noun 'face'.
Sense | Definition |
---|---|
yüz1 (hundred) | The number coming after ninety nine |
yüz2 (swim) | move or float in water |
yüz3 (face) | face, visage, countenance |
After annotating sentences, you can use DataGenerator package to generate classification dataset for the Word Sense Disambiguation task.
After generating the classification dataset as above, one can use the Classification package to generate machine learning models for the Word Sense Disambiguation task.
You can also see Java, Python, Cython, C++, Js, or C# repository.
Install the latest version of Git.
In order to work on code, create a fork from GitHub page. Use Git for cloning the code to your local or below line for Ubuntu:
git clone <your-fork-git-link>
A directory called NER-Swift will be created. Or you can use below link for exploring the code:
git clone https://github.com/starlangsoftware/WordSenseDisambiguation-Swift.git
To import projects from Git with version control:
XCode IDE, select Clone an Existing Project.
In the Import window, paste github URL.
Click Clone.
Result: The imported project is listed in the Project Explorer view and files are loaded.
From IDE
After being done with the downloading and opening project, select Build option from Product menu. After compilation process, user can run WordSenseDisambiguation-Swift.
In order to sense annotate a parse tree, one can use autoSemantic method of the TurkishSentenceAutoSemantic class.
let sentence = ...
let wordNet = WordNet();
let fsm = FsmMorphologicalAnalyzer();
let turkishAutoSemantic = TurkishSentenceAutoSemantic(wordnet, fsm)
turkishAutoSemantic.autoSemantic()
