IR-NLP Lab Faculty of Computer Science University of Indonesia

The IR-NLP Lab at the Faculty of Computer Science, Universitas Indonesia, focuses mainly on the research areas of Information Retrieval, Speech Processing, and Computational Linguistics.

Our Mission

Elevating Research Through Minimalist Design

Kingster University was established by John Smith in 1920 for the public benefit and it is recognized globally. Throughout our great history, Kingster has offered access to a wide range of academic opportunities. As a world leader in higher education, the University has pioneered change in the sector.

What We Do

Advancing Information Retrieval and NLP through systematic, insight-driven research.

Information Retrieval

Information Retrieval seeks to explore the methods and techniques of organizing, representing, storing, and searching of information in textual and multimedia forms (speech, image, and music).

In our lab, we have conducted several research topics in the area of information retrieval:

  • – Cross Language Information Retrieval
  • – Geographic Information Retrieval
  • – Music Information Retrieval
  • – Image Retrieval

Natural Language Processing

Natural Language Processing is a field which tries to model natural language in formal rule representation, or formalism grammar. This representation can be categorized into phonetics, morphology, syntax, semantics, and discourses. 

We have developed several NLP tools, especially for Indonesian Language, such as:

  • – Indonesian Stemmer
  • – Morphological Analyzer
  • – Part-of-Speech Tagger
  • – Named Entity Recognizer

Language Resources Development

Indonesian Language is still considered as an Under-resourced Language, which means that we are still lack of language resources to support most of the natural language processing tools.

In our lab, we are also developing several language resources such as:

  • – Indonesian Treebank
  • – Indonesian WordNet
  • – Lexicon (KBBI)
  • – Text Corpus & Speech Corpus

Text Mining & Knowledge Management

Text Mining seeks approaches for structuring textual data, deriving patterns from the structured textual, and finally interpreting and mining useful information from the results.

We have been doing research on the following areas of text mining:

  • – Text Summarization & Classification
  • – Text Clustering & Sentiment Analysis
  • – Information Extraction
  • – Mining User Generated Contents (UGC)

Machine Translation

Machine Translation is a sub-field of computational linguistics that seeks computational models to automatically translate text or speech expressed in one language to another language. The Lab has been publishing several works in this area, especially for Indonesia-English translation.
