sõnagraafs

Sõnagraafs is an Estonian term that translates to "word graph." It refers to a visual representation of the relationships between words within a text or a collection of texts. This concept is rooted in linguistics and computational linguistics, often employed in natural language processing and text analysis.

A sõnagraafs typically uses nodes to represent individual words and edges to depict the connections or co-occurrences between them. The strength or type of relationship can be indicated by the weight or label of the edges. For instance, an edge might signify that two words frequently appear together, are synonyms, antonyms, or belong to the same semantic field.

The construction of a sõnagraafs can vary. Simple methods might involve counting adjacent word pairs, while more complex approaches utilize co-occurrence matrices, dependency parsing, or semantic similarity measures. The resulting graph can reveal patterns of word usage, thematic structures, and the overall conceptual landscape of the analyzed text.

Sõnagraafs have practical applications in areas such as information retrieval, where they can help understand query intent and document relevance. They are also used in lexicography, in the study of language evolution, and for generating word association norms. By visualizing word connections, sõnagraafs offer a powerful tool for exploring and understanding the intricate web of language.
