Design takeaway

When designing tools for languages with sparse digital resources, consider adapting robust algorithmic approaches and investing in the creation of targeted linguistic datasets.

How to apply

Adapt the trie, dynamic programming, and weighted Levenshtein distance algorithms to create spell checkers for other languages with limited digital footprints. Focus on building relevant lexicons and error corpora.

Project actions

  • 01When choosing a language for a design project, consider if there are existing digital resources or if you'll need to create them.
  • 02Explore how algorithms like tries and dynamic programming can be applied to solve design problems, not just in language.

Method & Evidence

AimTo develop and evaluate a spell checker and correction tool for the Wolof language using a combination of data structures and algorithms.
MethodAlgorithmic development and empirical evaluation
ProcedureA spell checker was developed using a trie data structure for efficient word lookup, dynamic programming for generating correction candidates, and weighted Levenshtein distance for ranking suggestions. Novel linguistic resources, including a lexicon and a corpus of misspelled Wolof words, were created through a semi-automatic annotation process. The tool's performance was evaluated based on predictive and suggestion accuracy.
ContextComputational linguistics, natural language processing, indigenous language technology

Strengths & Limitations

Strengths

  • +High accuracy achieved for an under-resourced language.
  • +Novel contribution of linguistic resources.

Limitations

The accuracy achieved is dependent on the quality and size of the created linguistic resources. Generalizability to highly divergent dialects or entirely different language families may require significant adaptation.

Reliability & validity

Reliability could be assessed by running the spell checker multiple times on the same set of misspelled words. Validity is supported by the high accuracy metrics achieved, indicating the tool correctly identifies and corrects errors as intended.

Think critically

How might the 'semi-automatic' nature of the linguistic resource creation process introduce bias or affect the generalizability of the spell checker's performance?
